I am just starting to get my head around my new note (gingerbread os) and almost all my bloatware wants usb modify permission, (I cant believe that it is considered acceptable that so much open access to all areas is considered acceptable, anyway I have purchased it and only have myself to blame).
Can anyone help to clarify if this permission to modify/delete usb storage is also allows read access and if the internal phone memory is also classed as usb storage in regard to this permission.
Is nothing ever sacred anymore why do I feel my life, thoughts, pictures, audio files, txt and mms is open for the world to see. Can anything be done without rooting my device to shield my life from the ever probing eye of google?August 18, 2012 at 2:01 pm #318Galaxy NoteMember
Most Apps need access storage (to write something) or internet. Usually you should not concern about this. If the app cannot access internet, no access to storage, it can do nothing.
If an app requires access your contact, location information, or messages, then you need check whether the app is reliable (e.g., read the reviews).
Android is based on Linux, so the privilege control is very effective and well-tested. Normally, if you don’t root your phone, the app will not able to get full control of your phone. Of course, some malicious apps may try to read the pictures and files, but usually they cannot access private info (e.g., contact list, which is manged by Android system).
The bottom line is to install apps from reliable sources (e.g., Google Play store) only. Unless it is necessary, do not root your phone.
Android is more secure than Windows phone, or iOS.August 19, 2012 at 4:56 pm #320AnonymousInactive
Thank you for your advice on this matter, it was not so long ago that google was was found guilty of collecting private data from unsecured personal wifi networks here in the UK whilst gathering information for their street map application. No appology was issued and even more importantly no explaination was provided as to why they felt acceptble to design the equipment andwhat they intend to do with the data they stole.
Is it possible that the modify/delete usb storage permission allows applications to read information stored in my internal memory and or sd card.August 20, 2012 at 2:54 am #322Galaxy NoteMember
If the OS (in this case, Android) wants to get your private information, you have no way to block it, because all info is managed by the OS.
Many people trust Android because its source code is open (although less than 0.01% users ever read the source code). So, there are no hidden backdoors. This is fundamentally different from iOS, or Windows.
But as a company, Google is still a profit-driven company. The greedy Wall Streets always want to maximize their profit. It may be evil sometimes, just like the example you mentioned.
Android assigns a unique user ID (UID) to each Android application and runs it as that user in a separate process. This makes it even more secure than Linux, at least theoretically.
So in Android, no application, by default, has permission to perform any operations that would adversely impact other applications, the operating system, or the user. By default, no application can read or write the user’s private data, and another application’s files, or access network. All apps by default can access their own files only, or files you set as globally readable/writable (e.g., video files you transferred to the SD card from your PC).
When you install a new app, it will let you know what kind of access it requires. Read/Write USB storage usually means read/write own files (generated by this app). If it wants to access camera, then your camera and photos taken by the camera will be accessible for this app.
Of course, you can manually set the permissions for each file/directory using ADB shell (you need familiar with Linux first).
So, in short, you can not prevent OS from “stealing” any info on your phone. But as Android is an open source project (although there are some critics on the licensing), unlikely, it will steal your personal info. This is one of the most valuable feature of Android. Unfortunately, most people just read it as free.
It is the Apps that may do bad things, theoretically including the apps built by Google. But most of the time, it is the third-party apps. For third-party apps, they always need ask for permissions to access personal info, your only choice is not to install it.
Please note, the Encrypt device or Encrypt SD is to protect your phone in case it is stolen or lost, not for apps.
