[Q] S4 Touch not responding
I picked up my S4 from Best Buy and got the insurance plan on it. A few weeks back, I dropped it, and the touch screen stopped responding. A simple reboot did not fix it. When I took it in, the Geek Squad guy took a look at it, then it looked like he booted it into recovery (though I didn't see exactly what he did) and did something there that fixed it without a factory reset. He gave a really quick runthrough of what he did, but since I wasn't the one doing it myself, I don't remember what he said.
Anyone here know what it might have been? It's happened again, and I tried recovery and clearing the cache, but that didn't help, and I didn't see any other options that a person free-standing in a room would use to fix something (no updates to apply from cache etc. and I tried clearing the cache to no avail) and I'm hoping to avoid having to either take it apart or *shudder* deal with a flip phone loaner for a few days while I wait for a replacement.
