Fix: Constantly rebooting of Android phones

Scenario: When you install a bunch of new applications from Android Market, you find that your Android phone not doing any good other than constantly rebooting at every few minutes (say five minutes in my case).

 

You don’t know which application is that  causing the reboots and you don’t have any idea as what’s going on with your Android. Moreover, your Android doesn’t let you do any activity on the phone as it remains busy getting rebooted all times.

 

Troubleshooting:

 

-1.   It’s quite possible that your Android applications configuration files residing on your SD card got corrupted. Try moving folder named “Android” and let your phone have it created then the Android  should start up all just fine.

1. Disable internet access from your phone to avoid any of the online updates that’s causing your Android to constantly reboot.

1. Use Android process explorer to view which applications constantly running on the system and their CPU and Memory usage.

 

1. Use Dalvik Debug Monitor to see what actions going on on the phone. What kind of errors, warnings and information events taking place.

Based on these observations, guess what application could be causing the reboots issue and then start uninstalling all such suspicious applications.

1. Ensure that there is at least 33% of your phone internal memory is available free for it to be able to launch the applications successfully.

 

1. Unmount your SD card for a while and let the phone be relaxed from it’s constant reboot issues.

 

1. Let your Android processor be cooled down and then bring the android up without mounting the SD card

6.  Observe the Android performance for couple of minutes (say #10) and then if it all behaves well then

7.  Mount the SD card and let the Android to come up

 

Cause:

1. System ran low on internal RAM resources and couldn’t launch the auto startups of newly installed applications
2. One of the rouge application caused your system to go into reboot mode
3. SD Card access might got broken due to constantly IO activity with the reboots
4. Android config files on your SD Card got corrupted, please have them recreated

 

Fix: Uninstall couple of Apps and make sure you have at least 33% of phone internal memory available free for your Android to operate. Avoid installing apps like dual SD mount, Apps2SD, etc.,. Have the “Android” folder on your SD Card recreated by the android by removing/renaming the existing folder.
