Samsung Sch-u370

[Rav116]

I have a Samsung sch-u370.  Recently the phone automatically powers back on every time I power the phone off.  I cannot seem to power off the phone.  I hit the power off button and then the phone powers off but then quickly powers back on all by itself.  Does anyone have any suggestions on what the problem may be? Thank you.

You can try removing the battery with the phone powered on; let it sit for a few minutes without the battery.  Then reinsert the battery and see if it powers up normally and shuts down normally after that.

Thank you.  I tried several time but it still did not work.

Press and hold the power off button?

Is the phone still under warranty?
