For about a week my Strat has been shutting itself off without warning in the middle of use. No shut down animation, just a black screen. Usually I can just turn it right back on, but today it got stuck in a boot loop. It will only display the Samsung logo, go to black, and do it again. Trying for a factory rest (Volume Keys and power button) does not work, the phone just resets and displays the Samsung logo again and again. Same issue with holding just the down volume key. Even after taking out the battery for a few hours, as soon as I put it back in the loop restarts regardless if I touch the power button. My phone is not rooted, and I have had it for about one year. My google fu is weak, and I have been unable to find any solution to this. Has anyone solved this issue? Thanks!
