ICS 4.0.4 update for Galaxy Note is arriving, globally

July 12, 2012 in Galaxy Note Guides, Galaxy Note News

ics-4.0.04-galaxy-note-300After 2 months of the initial ICS update(4.0.3) for Galaxy Note, Samsung now quietly roll out ICS 4.0.4 globally. I was a bit surprised when I saw the update notification, because I just got the information the 4.0.4 update would be roll out gradually.

Apparently, immediately after releasing the ICS update for AT&T’s version Galaxy Note on July 11, Samsung also pushed out the ICS 4.0.4 update for Galaxy Note users in German. And today, more regions including most European countries and Asian countries get the Android ICS 4.0.4 update for Galaxy Note.

Hopefully, this update will solve some of the battery issues most users experienced in GB and ICS 4.0.3.

Now, all Galaxy Note users are expecting the next major update for Jelly Bean (Android 4.1). The information we have is that Galaxy Note  and S3 will get the Jelly Bean update, probably in Q1 2013.

Also, the coming Galaxy Note 2 (with ICS pre-installed, not Jelly Bean) will be very likely announced in the IFA 2012 (August 31-Sept. 5) and start to shipping in November (roughly one year after the release date for Galaxy Note) . So, hopefully, in the Q1 of 2013, both Galaxy Note and Galaxy Note 2 will get the Jelly Bean (4.1) update.

Anyway,today’s minor update (from 4.0.3 to 4.0.4)  is about 100MB.  So, please try to download through WiFi or Kies if your mobile data is very limited.

Any questions? please post the  in the comments section below or in the Galaxy Note Forums.

Why did I get less free RAM after the ICS update in my Galaxy Note?

June 28, 2012 in Galaxy Note Guides

Some users felt the sluggish immediately after the ICS update on the Galaxy Note. Some users even want to go back to Gingerbread, as commented by some users on the post of Top 10 questions on ICS update for your Galaxy Note and Ice Cream Sandwich is coming to your Galaxy Note

Of course, it is NOT necessary to go back to GB. Don’t over-react on the feeling. In this post, I will share with you how to read your available RAMs, and some tips to make your Note more responsive.

During the ICS update, for some unknown reasons, all apps will be started (we all know all apps will be re-installed by the updater, but I am not sure why they are started). So, after the update, your Note will not so responsive. A quick solution is rebooting your phone after the update. Most apps will not run automatically, so, after the reboot, only some apps started.

Now, you can check your memory (RAM) usage through Settings–Applications–Running. You should have 200-400MB free RAM. This is more than sufficient for most apps!! For example, for my note as shown below, it still have 299MB free RAM after running a few days.

ram-reported-by-system

This shows the actual available RAM.

But if I use the bundled Task Manager, it reported only 101MB free RAM as shown in the screenshot below. This is why a lot of  users get scared!. Do not trust any task manager or system info apps. Most of them suck. Most of apps report available RAM inaccurately.

ram-reported-by-task-manager

This shows why most Task Manager suck!

Wait a minute, the specification says my Galaxy Note have 1GB ram, but it shows I only have about 800MB.  Is Samsung cheating us? Surely not. The about 200MB RAM is reserved by the system, mainly for GPU.  In your Galaxy Note, there is a GPU (Mali 400-MP, to be precisely) whose duty is to render whatever to be shown on the screen. All such embedded GPUs do not have “dedicated” memory: they have to share the system RAM (your 1GB RAM). As GPU need contiguous (both physical and virtual)  address, memory should be reserved.  This is something similar (but not identical)  to your integrated graphics card on your PC (if you still have such a PC).

Your Android kernel (ICS) and drivers will use about 200MB RAM. Another about 200MB were used by your launcher and other bundled apps (both essential and bloated). So, after rebooting your Galaxy Note, you should have 300-500MB available RAM. Don’t use any task manager to check!! 

Android (and its father or mother? Linux)  is very efficient in memory management. Any unused RAM is wasted!  Android caches some apps in the RAM so that when you want to launch these apps, it will be super fast because they will be loaded from memory instead of from the storage card. Most of the time, your newly closed apps get higher priority of being cached. Of course, Android will not use up all your RAM; it will always leave 100-200MB as unused in your Galaxy Note so that you can launch any apps without feeling the sluggish. If the unused RAM is not sufficient, some cached RAM will be released immediately based on priority and other factors.

So, you should never worry about RAM management in your Galaxy Note. Most task managers and RAM boosters are useless.

If you feel the phone is sluggish, the problem can be caused by some poorly-written apps or some other settings (e.g., excessive power saving settings). You can always check the running apps from Settings–Applications–Running to find out which app is hogging the resources.

As mentioned, some apps start itself automatically when you reboot your phone. If you are curious to know which apps in your phone will start automatically (usually during boot time), you can install this Autorun Manger (https://play.google.com/store/apps/details?id=com.rs.autorun). If your phone is not rooted, you can only temporally stop such apps through Settings–Applications–Downloaded–choose the app–Force Stop. Anyway, for most users, this is NOT necessary.

Ok, a few tips to make your phone more responsive:

  • Turn off Power Saving. Based on my personal experience, the Power Saving can extend the battery life only about 10%, and your CPU seldom goes to 1.4GHz with Power Saving on. I tested for a few days. When it is off, my Note became far more responsive,and may battery is still enough for my daily use. Occasionally I still turn it on if I know I need user it for longer time on some days.
  • Turn off Screen Rotation. You can always turn it man when you need it, e.g., browsing web pages, watching videos.
  • Turn off Touch sounds and vibrate on touch. You can do this from Settings–Sound–System

What are your tips to make your Galaxy Note more responsive? Or do you have comments to share with us?

 

AllAboutGalaxyNote updated: from one-way communication to N-way

June 24, 2012 in Galaxy Note News

galaxy-note-owners-communityYou may already notice this blog was updated this weekend: from a blog to a community.

Blogging is an effective to share experience, to discuss some specific issues with a small group peers. This is the original format of AllAboutGalaxyNote.com, powered by WordPress.

However, when a blog post has 100-200 discussions, the limitation is obvious: it is hard to navigate (although WordPress is really a solid platform). In addition, it is very hard for a visitor to start a new topic  due to the default security control in WordPress. So, an integrated forum is needed.

Sometimes, some people prefer private discussions. This is also hard to implement in WordPress.A private messaging system would be also helpful.

After some comparison, I chose BuddyPress, which is a social plugin for WordPress to extend the functions of WordPress.  So, all contents (posts and comments) are preserved. Now we get additional features with this update:

  • Private messaging (for registered users)
  • Forum
  • Chat room (coming soon)
  • Facebook integration (some users want to receive update from Facebook)
  • Google+ page (again, some users, like me, prefer receive update through RSS or Google +)

Now the communication is N-way.

Please give us feedback on any features, as well as your other suggestions.

What else do you want to have here?

 

 

 

How to solve battery issues after ICS update in your Galaxy Note

June 17, 2012 in Galaxy Note Guides

galaxy-note-battery-issuesAfter ICS update, some Galaxy Note users complained about poorer battery life compared with that with Gingerbread. Initially, I thought it is a problem of “feeling” because I personally felt similar battery life after the ICS update. I was a bit disappointed because I had expected some sort of battery life improvements.

Suddenly, last week, I encountered the battery drain issue: battery just draining crazily. In one hour it can drain 3-10% battery capacity when the phone is idle. So, I know the users complaining are not alone.

As I finished my investigation and found the culprit, now I share with you how to solve battery issues on your Galaxy Note after the ICS Update. If you already have battery issues or you feel you have battery issues, you may follow my steps.

First, I installed an free app called CPU Spy (https://play.google.com/store/apps/details?id=com.bvalosek.cpuspy), which will give you the duration of  each CPU state. When your phone is idle (screen off, no music playing, no downloading), normally, your CPU should be in “Deep Sleep” state. For example, after one night, you check your CPU Spy, it should look like this.

cpuspy-normal

Normal CPU state in a Galaxy Note when you are sleeping.

As you can see, this is the normal situation. In the night, 95%of the time, the CPU is in deep sleep, and after 11 hours, about 6% battery was drained (I also checked emails before sleep).  If your phone does not go to deep sleep, you will find the duration on other state is higher. Very likely, you have battery drain issues if more than 20% battery are drained when you are sleeping (6-10 hours),  You probably will find far larger percentage on 200MHz state. If more than 30% are drained in one night, very likely, your phone never goes to Deep Sleep state.

So, install the CPU Spy (free), use your Galaxy note as usual for a few hours,  fully charge your phone, disconnect your Note from the charger, close all apps (it is NOT necessary to clear the cache; but is a good idea to disable WiFi). Then go to sleep. Check the battery status after 6-10 hours (if you can sleep that long).

If the battery drain is less than 1% per hour  (this gives discharging rate of less than 25mA, as your Note has a 2500mAh capacity) in idle state, you phone should be able to go to deep sleep state and don’t worry for the battery drain issue for the time being (as you may encounter another issue as I did).

If your phone drains battery faster than 1% per hour when you are sleeping. It means the phone has an insomnia problem. You need find out which app casues the problem.

Now you need installed another app named Better Battery Status (https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats&hl=en). If you want to support the author for this incredible app, you can buy it for about $2. Yes, if you are just want to do a short time test, you can download the identical (and also official) free one from XDA-Developers (http://forum.xda-developers.com/showthread.php?t=1179809). This is an official copy the author released for XDA-Developer community for free. You can find the download link for the APK file in the second post. Once the APK file is saved on your Note, you can then use any file exploer (e.g., MyFiles) to browse it and you will be offered to install it. Please make sure the Unknown sources is checked (under Settings–Security–Device Administration) if you install from APK file instead of the paid one from the Play store.

Once you start Better Battery Status, you can straightaway see a lot of info. You can select Partial Wakelocks since unplugged if you want to find out which app prevents your phone from going into deep sleep.  Here is an example (normal situation, no issues).

better-battery-status-app

This is a normal situation; no major issues.

So, in the past 19 hours, some apps just keep the phone awake for a few mins. If you find any apps that listed here has long time associated with it (do NOT judge on the length of the bar; you should make judgement based on the percentage of this time to the total time), congratulations, you find the culprit. You can proceed to check the app settings.

Again, the image above indicates there are no problems. The longest partial wakelock is only a few mins. Don’t be panic when you look at the bar.

As I told you at the start of this post, last week I encountered battery drain issues caused by the kernel, possibly a kernel bug. All of a sudden, my Note went crazy: draining the battery very fast. Initially I though it could be caused some apps. But after I checked the battery status, I found out it was caused by the kernel  (fuel_alerted).  and here is the screenshot.

better-battery-status-kernel-wakelock-fuel-alerted

If you encounter this fuel_alerted guy, you have to shutdown your phone, remove the battery.

Anyway, this is a kernel bug in ICS, we have to wait for new update. The solution for this is: shutdown your Note, peel off the back cover, remove the battery; hold the battery for more than one min, put the battery back, put back the back cover; start the phone. Then, everything goes back to normal. Reboot your phone will NOT solver this issue, at least for me.

Next time, when you encounter this issue again, try the procedure again.

But it seems it is hard to hit the bug again. I tried to enable/disable power saving; tried to reboot, tried to turn on/off GPS, I simply cannot get the problem again. I know the problem is NOT fixed, it will come out someday, but I don’t know when.  We have to wait for another update to permanently fix this issue.

Do you have any other battery issues?

 

Top 10 questions on ICS update for your Galaxy Note

June 4, 2012 in Galaxy Note Guides, Galaxy Note News, Galaxy Note Stories

galaxy-note-ics-update-girl-with-phonesYes, ICS update is available for about one third Galaxy Note users. To get the most current    status on the availability of ICS update in different regions, you may check this post (I will update it once new info is available).

I received some inquiries on ICS update for Galaxy Note: some are through comment of the post mentioned above; others are through Google+.  For all these questions, I tried my best to answer them, and will continue to answer them.

I noticed there are some repeated questions, so I decided to put some frequently asked ones in this post to save reader’s time. It will not be just 10, as I will always update it if it is necessary.

Question #1. Why did some users get the ICS update earlier than me? 

Normally, firmware update must go through local testing. For regions with more users (and so Samsung collected more money there), the testing usually is faster. And Samsung also may put some sorts of priority for such regions.

The second reason is that the local carrier may want to bundle more bloatware (in addition to that bundled by Samsung). This may slightly delay the update availability. If your handset is subsidized, the carrier always tries very hard to give you more bloatware.

Another possible reason is marketing scheduling. For example, if Samsung is planning to launch Galaxy S3 in your region, usually it is not a good idea to release ICS update for Galaxy Note (another flagship product) just a few days before the launching event. In this case, the update will be normally scheduled after the event.

Question #2. Why should I update to ICS?

ICS update for your Galaxy Note is just a software update. Software generally is getting better and better: more stable, more functions, more compatible apps. Android 4.0 (ICS) is a major update merging software stacks for phone (Ginger Bread) and tablet (Android 3.0, Honeycomb). So, it is almost perfect for Galaxy Note, which is somewhere between phone and tablet.

Specifically, with ICS update for your Galaxy Note, you get

  • Latest Android OS optimized for the form factor of your phone
  • Premium Suite makes your Note really outstanding from other phones and tablets
  • Some cool features included in ICS: face unlock, new default font

Question #3. Will all my apps works after the update?

Theoretically, all of them should work. But some apps may actually not. So, it is a good idea to check the individual app page in the Google Play to find out whether it works on ICS  or not, or whether there are some known problems.

Normally, for apps under active development (e.g., updated at least once in last 6 months), the developer very likely has tweaked the app for ICS.

Question #4. Where is the Premium Suite? I cannot find it after the upgrade.

Premium Suite is a collection of new apps (S Note, My Story) and  enhancements to S Memo and S Pen.

After the ICS update, you can find a new app, S Note, among your apps. You can start to use it immediately.

In some regions, the My Story app must be installed manually from Samsung Apps. You can go to Samsung Apps (an app installed by default), then search “My Story”. You can then install it. When you try to open it the fist time, you need register your mobile number (an SMS with a 4-digit pin code will be sent to your mobile for verification, so make sure the country code you select is correct).

If you cannot find the app through Samsung Apps, you can also try to use Kies.

Question #5. How to get My Story app? It is supposed to be included in the Premium Suite.

See Question #4.

Question #6. Are there battery issues with the ICS update? I heard some complaints on poorer battery life and performance after the update.

Based on my personal experience, there are no noticeable difference in battery life after the ICS update. I actually had expected some improvements. For most users, it is sufficient for full day use, and you probably need charge it every night, just like me.

Actually, you may hear complaints on battery life for almost all smartphones regardless of the OS, firmware, model and the brand. Most of the time, the only solution is a replacement. I guess this is very likely hardware defects.

Of course, sometimes, some poor written apps may drain battery quite fast. But this can easily found out.

On the performance, most of the time, it is just user’s “feeling” or the slowness experienced may be just related to specific apps.

It seems after the ICS update, most apps are started automatically when you reboot your phone. So, you may try to use force stop for most of the apps or kill them with some task managers. This may make your Note more responsive. (If you can use force stop for an app, it means the app has been started. Some task managers may miss most of them, it is better to do it manually to save your battery life significantly.)

Anyway, I feel the battery life is as bad (but acceptable) as that before the update. Performance is as good as that before the update. No major improvements, and no degradation.

Update: yes, even before the update, some users already have battery issues. Please check the post How to solve battery issues after ICS update in your Galaxy Note.

Question #7. Can I easily root my Galaxy Note after the ICS update?

Please note, in most regions, rooting your Galaxy Note may void your warranty. And, no rooting method is perfect.

Yes, Samsung phones are always easy to root. After the ICS update, you can root it with CWM  (http://forum.xda-developers.com/showthread.php?t=1647148 ) or PC Odin (a bit more difficult if you never use Odin before, so I do not give your reference).

Anyway, unless you are very familiar with Android, you should not root your phone within warranty period (usually one year only) to avoid any possible issues. For most users, you don’t need root/superuser access.

Question #8. Does face unlock work well on this ICS update?

Yes, face unlock works very well on Galaxy Note. But please note, this is not a good option if security is your big concern. Password is still the safest unlock method, followed by pin code. Face unlock can be easily cheated by a photo as reported before.

Anyway, face unlock is very cool and fun.

Question #9. Why did I get the update only from Kies, not through OTA?

In most regions, the update can be obtained both through OTA and Kies. But it seems in some regions some users cannot get the update from the OTA.

The reason you cannot get the update through  OTA is mainly caused by your local vendor/carrier. Some carriers simply do not want to enable the OTA update. Another possible reason is the update server is overloaded. I also heard (unofficially) if your connection speed is regarded as too slow, you probably will not get the OTA update popup at all.

Anyway, Kies is more reliable, although sometimes is a bit slow. Familiarize yourself with Kies if you want to use Samsung phones effectively.

Question #10. Will I get Jelly Bean (Android 5.0 4.1) update for my Galaxy Note?

I contacted several Samsung offices with this question, and nobody could give any useful info. The common answer is it will be announced after Jelly Bean is officially available.

So, let me guess.

If there is no Galaxy Note 2 or some models to upgrade Galaxy Note, we will very likely get the  Jelly Bean maybe next year. The only problem is whether the 1GB RAM is sufficient or not for Android 5.0.  It seems 1GB is very likely the minimum requirement for Jelly Bean.

Updating Galaxy Note to Android 5.0 does make business sense. As the note was just release in Q4 last year, most users’ 2-year contract will only end by Q4 of 2013.The lifespan of ICS is not so long.

However, if there are something like Galaxy Note 2, then, we will definitely NOT get the official Jelly Bean update because Samsung then wants to sell more of  the new model. Just like the fate of Galaxy S. Very likely, Samsung will give you some consolations like new premium packages.

I guess Samsung was not very confident about the popularity of Galaxy Note even after the  initial release. So, they probably did not have a  plan for Galaxy Note 2.  But as the sales of Galaxy Note become far better than expected, it is very likely they started to think about a new Galaxy Note (not the Galaxy Note 10.1, which is targeted for different users.)

Anyway, there will be at least some unofficial Jelly Beans for Galaxy Note.

Do you have any other questions on Galaxy Note? Post them in comments (it won’t show up immediately, but I will receive it immediately and try to answer it ASAP).

Galaxy Note Android 4.0 ICS source code is available now, why Samsung must release the source code?

May 23, 2012 in Galaxy Note Guides, Galaxy Note News, Galaxy Note Reviews

Today, Samsung finally released the Android 4.0 (ICS) source code for Galaxy Note. If you are enthusiastic developer, you can work out your own ROM now very easily. Very likely, within one month, several different flavors of Galaxy ICS ROMs will be floating around.

open-source-softwareWhy does Samsung (and all other licensed Android hardware manufactures) have to release the source code to the public?  This is simply the obligation of using Android, because Android is using Apache license 2.0 except the Linux Kernel (which uses GPL v2 license).

Under Apache 2 license, user has the right to get the source code so that they can modify as they want (although this very likely will void the product warranty). So, the manufacturer MUST make the source code available to users, but it is NOT necessary to be under Apache license. For example, Samsung has its own license on using the the Android source code released by Samsung.

The Linux Kernel is released under GPLv2 license, which requires all modified work must also be released under such a license. Sometimes, this is named as “copyleft” license. Under this license, user get more controls of the source as manufactures are NOT allowed to impose additional terms on using the source code.  But due to its copyleft obligation, manufacturers usually want to avoid such license for competition reasons.

Although there are some critics on the openness of Android project,  Android is unarguably the best open source OS for mobile phones. It gives you the freedom you deserve.

This is one of the biggest advantages of using open source software, for consumers. You are not locked in; you can check how good or how crappy the code is.

For fruity fanbois, or M$ slaves, they never understand what freedom means, as a consumer.
