    Us cellular pre paid samsung galaxy s2 SCH-R760 just started shutting itself off and on and also lighting up and going dark like I'm pushing the power button to access the screen but I'm not. Haven't dropped it or anything. It happens literally ever 3-4 minutes over last week. Took it to us cellular the guy told me it's my battery, which it's not I have 3 batteries and it does it on all three. So then he told me it probably had corrosion, which I don't know how cause I do not take it in kitchen or bathroom or anything I'm very careful due to the fact that I have pre paid and no insurance. The power button seemed fine from outside but now will not turn off or on by button it stopped working completely. To get screen to come on I have to plug it in to power cord. When I take battery out and put it back in it comes back on automatically. and this doesn't happen when it's plugged in to power cord. Please someone help I can't afford a new phone..

    Welcome to Android Central! Try booting into Recovery and clearing the system cache partition. You won't lose any personal data. [Guide] Rebooting into Recovery Mode for the Galaxy S2, S3, and Tab2.

    It doesn't really sound like a boot loop--that where it tries to boot, then shuts off and powers back on by itself, never quite getting to a stable situation. I can't really tell you what's going on, the cache partition wipes can sometimes correct these situations. There's no harm in trying it.

    Welcome.

    It may be worth making sure first that the battery, power switch and other related internals are good.
