Sony xperia e3 comes on bit then turns its self off and on and of again

Solution
Hmm, perhaps there is a software/firmware glitch or even an app that is causing the problem. Try loading it in "Safe Mode" (instructions below) and see if it will actually turn on and stay on. If it does stay on, then you need to find what app or other downloaded software is causing it to keep resetting. I would look at uninstalling anything new, and removing any recent updates, then restart the phone out of "Safe Mode" and see if it has the problem again.

To get into "Safe Mode" please do the following.

1. First turn off the phone.

2. Next press and hold "Power" until you see the manufacturers logo on the screen, then release the power button.

3. "Quickly" press "Volume Down" and hold it for few seconds until you see the message...
