What will i do when my phone keeps on rebooting?

[Davedo]

I got some problem with my galaxyS5 it keeps rebooting when I power it on . I already hard reset it, but it still did not solve the problem it still keeps rebooting ( I mean it power on then it power off it won't even reach the home screen then it power on again then power off, I can't do a thing with it not even pressing the hot keys unless I take the battery off.I'm sure it won't stop till the battery's dead or when I take of the battery)

Welcome to Android Central! The first thing I'd try is a new or different battery.

mine kept doing that from the beginning. about 9 months in, I had to reset back to factory and it hasn't done that since and my volume is so much better.
