Phone Data

Step 1 Turn off your Android device. Reboot the phone or tablet into Recovery Mode. The process is specific to the device model. For the Motorola Droid, press and hold the "Power" button and the "X" key on the slideout keyboard. Release the "Power" button when the Motorola icon appears. Press the "Volume-up" and "Camera" buttons simultaneously to open the Recovery Console. To access Recovery Mode with the LG Ally, press and hold the "Power," "Home" and "Volume" buttons simultaneously.
Step 2
Press the "Volume-down" button to scroll to "Wipe Data/Factory Reset." Press the "Camera" button to select it.

Scroll to and select "Wipe Cache Partition."
Step 4
Highlight and select "Reboot System Now."

It is highly possible that the system has been corrupted. Your best bet is to hard-reset the android. Usually, it is achieved by turning off the device, then press Volume Down + Power until the recovery console appears. You can then use the Volume Controls to select your choice (usually Factory Reset) then press Power to execute your choice.

dear,
most probably it happens with stuck button. may be the casing is not properly fixed with the phone. check it first. sometimes, it happens, that a button seems to be ok but physically it is stucked. if problem persists, then try with removing the memory card and do a master reset, if necessary
