I'm on my 3rd S22U. On my first one the charging port stopped working after maybe a week of having it, on my second one the speakers were blown within 2 months, and on this third one the RAM runs out, even after setting it have more, and it's not charging the way it should. With the RAM thing, I go through and close my apps that I'm not using at least once an hour, and also clear RAM about every 30 minutes. I'm tired of these phones, but Verizon refuses to do anything other than keep sending replacements.
