why my phone self on off

[AC Question]

why my phone lg f160 self on off again and again

 

[belodion]

A poor battery connection? A faulty Power switch?
Also, does it persist in Safe Mode?

If it happens when you bump the phone, it's probably a loose battery like belodion says. Pull out the battery and clean the gold contacts gently. Put back in, if it seems loose, pack a bit of tissue behind it to push the battery onto the contacts..
