Taken from

Q&A coming soon from cooleagle

Basic noobie questions:

Q1: What is Android? I heard that my phone has this as said by the guy who sold me this phone......
A1: Hello new user, Android is an Operating System (a.k.a OS) for phones, like how Windows is for computers. It is meant to be simple, efficient and customisable.

More can be seen here:

Q2: What is root? What does it do?
A2: Rooting is the process of attaining superuser (su) access to your phone. It is similiar to the jailbreaking process on Apple phones

Q3: What are the different Android versions available for our phone?
A3: Currently only 2.3.3 to 2.3.6. Don't worry, Cyanogenmod 7 will have 2.3.7

Q4: I've heard all this commotion about "stock" firmwares. What are they?
A4: Okay, stock firmwares are update files from Samsung which are available for download. This stock firmware may also stand for factory firmware (if you didn't update)

Q5: What's build.prop? What are some of the build.prop tweaks and meanings?
A5: Build.prop is a file that defines the build properties of the build and phone. It is a necessary part of the phone and if it's missing, the phone may not be able to boot.
Here are some build.prop tweaks:
pm.sleep_mode=(0 or 1)
Enables the phone's sleep mode.
0 to disable, 1 to enable. or 1)
Disables the network power collapse, allowing the phone to sleep better.
0 to disable, 1 to enable tweak.
dalvik.vm.heapsize=(amount in mb, e.g 48m)
Defines the Dalvik Virtual Machine Heapsize for games to run better.
ro.sf.lcd_density=(0-999, Galaxy R default is 240)
Defines the LCD density (in dpi) for your device. It's recommended not to change your density for Samsung phones as they will cause problems with your phone's Dialer service.
wifi.suppliant_scan_interval=(time in seconds, e.g. 60)
Defines the time taken to scan for new WiFi networks if no open networks are found. Setting the option higher may save more battery as it scans lesser. or 1)
Turns off the camera shutter sound (Be careful with this, it may be illegal in yoir region!)
You can also try this suggestion by pudup:

1. This one is kinda annoying but if the sound annoys you more, you could just put your phone on silent or hold the volume down button until the volume is off. The camera shutter sound shouldn't be heard.

2. Download an alternate camera application. Eg. LGCamera.

3. Wait for the CyanogenMod 7 rom. That has the option to disable the sound in it's settings.

0 to turn sounds, 1 to turn off sounds.
video.accelerate.hw=(0 or 1)
Enables hardware decoding of videos. Only for video formats natively supported by phone.
0 to disable, 1 to enable., 1, 2 or 3, default is 1)
Determines the speed of your HSUPA.
0 = HSUPA disabled (very slow upload)
1 = Stock HSUPA enabled and capped (slow upload)
2 = HSUPA enabled but capped (good upload)
3 = HSUPA enabled and uncapped (best upload)

Q6: Does this phone support overclocking? I feel that I'm not getting the most out of this phone :/
A6: Yes this phone does support overclocking. The kernel by ardatdat should be in the Development section. It even supports undervolting to save battery!

Q7: Why is there a yellow triangle below "Samsung Galaxy R GT-i9103" on boot?
A7: That's because you probably flashed a non-stock kernel through Odin3. Try reflashing a stock ROM and use CWM to flash the phone next time.....

cooleagle and I will add more info to come

Guide 1: How to make use of ADB (Android Debug Bridge) for debugging and testing

By now, you all should've known that Android makes mistakes. Actually, not just Android. EVERYONE makes mistakes. Well, for this case it's something going wrong with a game, or just something wrong with a ROM.

The developers @ Google were smart enough to make this logging binary called
and it logs everything going on inside Android, from bootup, to dexopt, basic processes and even to shutting down!

There are 2 ways of accessing Android's logcat:

WAY #1: Using Terminal Emulator

  • A working phone that boots
  • Rooted with Superuser

  • It's harder to debug using the phone, especially if it is stuck at the bootanimation or splash screen.
  • Root is needed otherwise you will get
    logcat: permission denied
    in the terminal

  1. Download Terminal Emulator from Google Play or the link above
  2. Once you've entered it, type in
    using the virtual keyboard
  3. Allow it in the Superuser prompt
  4. Then go ahead and type
    , you will see a bunch of crazy things.
  5. If you want to save a log, do:
    logcat > /mnt/sdcard/logcat.txt

WAY #2: Using Windows/Ubuntu for logcat using the Android SDK (Software Development Kit)

  • Allows debugging using the computer for more accurate findings
  • Allows logging much better than the method in Terminal Emulator
  • Ubuntu allows live copy/paste in its Terminal so there is no need to save a log.txt file

  • It uses the Internet to download the required packages
  • You need a USB cable to connect the phone
  • If the USB cable/port is malfunctioning logcat will not work
  • This is more complex than the phone method as it requires you to set a path in Windows's environment and in Ubuntu's .bashrc if you want to be able to use it in the Terminal/Command Prompt at any time.

Steps for Windows:
  1. Launch the Android SDK Manager in
    32-bit Windows:
    C:\Program Files\Android\android-sdk\SDK Manager.exe
    64-bit Windows:
    C:\Program Files(x86\Android\android-sdk\SDK Manager.exe
  2. Wait for it to finishing loading all the repositories
  3. Install the Android SDK platform-tools and let it finish its install
  4. You have now installed the Android SDK's Platform Tools, which is in
    C:\Program Files\Android\android-sdk\platform-tools
    and it contains the Android Debug Bridge (adb.exe), which fits this description:

    The adb tool has moved to platform-tools.

    If you don't see this directory in your SDK, launch the SDK (execute the android tool) and install "Android SDK Platform-tools"

    Please also update your PATH environment variable to include the platform-tools/ directory, so you can execute adb from any location.

  5. To test whether adb will work, run Command Prompt and go to the folder described above , respective for 32 and 64-bit.
  6. Run:
    adb logcat
    and if it works, the same crazy code will be there

Q. Does Galaxy R have a locked Boot loader?
No, it isn’t locked and you can flash custom ROMS & Kernels, but do read the terms and conditions & instructions before rooting/ flashing as it can void your warranty.
But there’s a workaround to unroot it & flash it back to the stock ROM & kernel to give it for repairs. Gather all the information required before rooting and root it only after you are confident of rooting it as its better be safe than sorry and brick your Galaxy R.

No, Samsung did not make a fool out of you.
It actually has 8GB internal storage which is divided as follows:
2GB ROM + 2GB for applications + 4GB user available.
Q. WTH my device shows only 724MB RAM available but I was promised of 1GB! I will sue Samsung!
Don’t sue Samsung you’ll surely make a fool of yourself.
Some part of the RAM is used by the OS & GPU and isn’t available to the user.

Yes it’s a known issue for devices on stock kernel. It can be solved by using ardatdat’s kernel as it has a fix for that or wait hoping that Samsung solves it in the next update.
Q. Does Galaxy R have any freebie Apps & Games from Samsung?
Yes it does ! There are so many available just go to Samsung Apps(Application) in your Galaxy R to get the full list. Specifically Modern Combat 3(by Gameloft) & Dead Space(by EA) are available for free.
Q. Can I retrieve my Galaxy R & protect my personal data if God forbid it’s lost?
Yes, you can but it depends on many variable factors to get a lock and use all the available features. It natively supports it by using Samsung Dive to:
  • Track your mobile.
  • Ring your mobile.
  • Send an SMS if the SIM is changed to a pre-defined number.
  • Erase all your Personal Data on the mobile.
Q. My Galaxy R has freezed/hanged ( It’s mostly due your antics or some app specific bug and not due to the device’s fault as it normally does not hang even on heavy usage ) What to do?
Hold the power button for more than 7 secs and it should automatically restart.
Q. Can I flash Custom ROMs?
Yes you can use Odin or ClockWorkMod(CWM) to flash them but beware you can lose your warranty.
Q. Does flashing increment my counter?
Yes & No. Wondering how both are possible? If you flash using Odin then it increments your counter but if you flash using CWM packages it doesn’t, so it depends on the method you use. But flashing a rooted / custom kernel will increase your counter even if you flash it using CWM.
Q. My device is DEAD & shows APX mode driver required on connecting to my PC! What to do?
You are lucky! Here’s a solution to it. Head to => LINK
Q. My device is not being detected on being connected to my PC but I can charge it via the wall / normal charger ! What to do?
First of all check if you have the latest Samsung Kies software installed as it also installs the latest Samsung USB drivers along with it which are required to connect your device to the PC. If they are installed & still your PC doesn't detect the device then you probably have corrupted drivers. To resolve this follow these steps: Uninstall Samsung Kies / Samsung USB drivers currently installed => Restart your PC => Reinstall Samsung Kies / Samsung USB drivers.
Q. I can't charge my device & my device is not being detected after connecting to my PC & Odin is not detecting my device ! What to do?
(The solution is valid only if you are experiencing all of the above conditions simultaneously)

Checkout this thread which could help you: => [Partial Fix] Galaxy R not getting detected on PC nor charging via a charger.
Q. I didn't backup my /efs folder and my IMEI is messed up ! Is there any way I could recover my IMEI number ?
There is a GUIDE to recover your IMEI for Samsung Galaxy S2, as being from the same manufacturer there is a chance that it may work but there is not guarantee that it'll work, you are going to use it completely at your own risk (it may hard brick your handset). I am not aware if any member was able to recover Galaxy R's IMEI using this method.
So if you willing to take the risk then Head To => Thread & do tell us if were successful in recovering your IMEI by following a particular procedure.
Q. Which Custom ROMs are available for Galaxy R?
  1. Infected ROM v2[2.3.6][ZSLE5]

  6. Anatasia ROM[2.3.6]
  7. Turkbey ROM[2.3.6]

  2. AOSP Build (No new developments)
Q. Which Custom ROMs do we want?(State it and I’ll update it here )
CM9, MIUI, AOKP, AOSP, PARANOID ROM & any other ROM with better features and functionality!!
So if you are a dev then kindly help or if your friends are developers don’t forget to request them to make it available for our device !

  • 3G / 2G Mobile Data count applications don't function correctly.
    Can be solved by using a custom kernel which has this bug fixed.
  • Date & Time of the handset changes randomly even when it's set to update automatically according to the network.
    Go to Settings => Date & Time => Uncheck & then Recheck 'Automatic' to re-sync with your carrier's / service provider's time & date. No known solution which permanently resolves the issue.
  • The person at the other end can't hear you at all / Headset Jack bug
    Sometimes after unplugging your headset you experience problems while making a call, usually a reboot solves the problem but sometimes it doesn't. It can be identified by the following symptoms: When you're making a call, the person at the other end can't hear your voice but you can hear them clearly / you pick up the call then you can't hear any voice & the person can't hear you either.

    It's most probably a software bug as the handset thinks the headset is still attached to the handset & routes the call as if it were being made when a headset would have been connected. But in some cases it could also be due to a hardware problem i.e a faulty 3.5mm headset jack.

    To confirm if this is the problem you are facing:
    - Plug in Samsung's headset & make a call to check if you can communicate / talk with the person at the other end normally & without any problem.
    - If you can talk normally then it's confirmed that it's due to a software bug if not then it could be due faulty 3.5 mm jack.
    To resolve it:
    - Update your firmware to the latest version available even though it may not be for your region as it could have possible fixes. i.e (ZSLE5 / ZSLE6 / Latest firmware of any region)
    - Plug in & out the headset a couple of times while playing music till it gets resolved i.e when the firmware understands that the headset has been removed & then it'll work normally.
    - You can also take it to a service center where they could replace the headphone jack & may also reflash the stock firmware which should resolve the problem if it's due to a faulty 3.5mm headset jack.

If any of the above helped please don't forget to appreciate by hitting 'Thanks'.
