Top 10 new features in Galaxy Note after ICS update

July 16, 2012 in Galaxy Note Guides, Galaxy Note News

After the official release of ICS 4.0.3 update for Galaxy Note  in May and ICS 4.0.4 update last week, some users asked me what the new features are. Thanks to Samsung’s Touch Viz UI, most users will not visually find any changes after the update. Here I prepared the top 10 new features in your Galaxy Note after the ICS update.

Each update fixes some bugs and the performance should be improved, so we usually recommend users to apply the update, although some new problems may be reported, e.g. battery issues, RAM issues. Given the short lifespan (1-3 years) of samrtphones, it is impractical to wait for the perfect firmware.

In this post I will try to introduce you the features. I will create  tutorials for some of these features later.

1. Pop- up play (ICS 4.0.4 update is needed)

pop-up-play-galaxy-notePop up play was debuted on Galaxy S3  last May. In the Googl Play store, there are a few paid apps (e.g., Stick it! (Pop-up Player)) doing the similar job. What it does is quite simple, you can watch your video and use other apps at the same time. The video will be re-sized as thumbnail and you can move it to any locations on your screen. Pretty cool, right?

Of course, only the built-in video player support this. Once the video is open, you can find the re-sizing (or pop up play?) button in the top right corner. If you want to stop the video, just touch the video area and release your finger. If you want to go to full screen, you can long press the home button to get the task manager and open the video player.

Two limitations: 1). the size of the video cannot be adjusted, at lest I did not find any ways to adjust it; 2). If you want to go back to full screen, the video will be played from the beginning, not from where you stop in the pop up play mode. Thanks to julien for correcting me. (Tap the video,  it will go back to the full screen and continue.)

2.  S Note

S Note is part of the Samsung’s Premium Suite for Galaxy Note and is installed as part of ICS update. It comes with 6 samples, 6-page S Note Tips, and a 6-page productivity Tools Tips. So, you can start to use it quite easily.

With S Note, you can directly convert your handwriting into text, convert your drawing into polygonal shapes, and convert your writing into mathematical formulas. You can even import PDF file for annotation!

After the ICS update, you should be able to find this app among your applications.

3. My Story

My Story is also part of the Premium Suite for Galaxy Note. But it is not installed automatically during your ICS update. You can download it either from Samsung Apps or Google Play store (https://play.google.com/store/apps/details?id=com.sec.android.app.mystory)

This apps help you create multimedia letter or a card or an album. It comes with 4 templates (birthday, thank you,  letter in a bottle, ans memory).

This apps need verify your phone number. So, when you open it first time, it will ask your phone number and a verification code will be sms to you. So, remember to provide correct phone number, especially country code.

4. Face unlock

Face unlock is a standard feature in ICS (Android 4.0). You can unlock your phone by using your face (and the front camera). You can turn on this by going to settings–security–screen lock. Of course, if the light is so weak, you cannot use this feature. So, your Galaxy Note will ask you to setup PIN or password as well in case your face is not recognized.

5. Notification

In ICS, notification is significantly improved. Shortcut for Settings is added there. From the lock screen, you can also launch apps directly.

6. Data usage monitor

ics-data-usageFor people with data quota, monitoring mobile data usage is important to avoid hefty and stupid charges from the greedy telecom operators. In the past, you may use some apps, e.g. 3G Watchdog to monitor the data usage. Now, it is not necessary.

Under settings, now you can find Data Usage. All your data usage will be reported here. You can set the limit, and disable background data if your data quota is very low.

7. Developers options

Occasionally, some background processes (usually from poorly written apps) may drain your battery  quite quickly, and hog on the ram. So, your system may be not so responsive. IN ICS, you can go to Settings–Developer options to setup the background process limit. You can choose No Background processes as a test if you suspect the battery drain is due to background process. Normally, you should not choose no background processes, as Android system may need this function to improve performance.

Under developers options, you have a quite a lot advanced controls, e.g., show CPU usage, or force GPU rendering.

8. Quick access to task manager/ Swipe to close

ics-task-manager-swipe-to-closeAt any time, long press Home button, you will get the task manger (pop up). From the thumbnail list of running and recent apps, you can swipe to left or right to close it . Touch it once to open the corresponding app.

9. Signature unlock (ICS 4.0.4 is required)

This is a cool feature, although not so useful. You can unlock your phone with your S Pen by signing on the screen. That’s it.

You can set it up from Settings–Security–Screen lock.

10. Chrome browser

ICS has a improved web browser. You can open up to 16   8 tabs (thanks for Thomas who found we can actually open 8 tabs in Galaxy Note, not 16, It seems Samsung gave us 50% discount.).  It sounds good?

Even better, you install Chrome browser ( https://play.google.com/store/apps/details?id=com.android.chrome) on your Galaxy Note. It is super fast and you can even share the bookmarks and browser windows with your desktop!.

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
