First off, lately it's been not turning the backlight on when I try to use it. I can hold it up to a light and see that the screen is on, but the light doesn't turn on. This doesn't happen 100% of the time, probably around 30% or so. I can't tell if it's softare related or hardware related, if I push the power button a ton of times I can get it to turn on.
Next issue is that last update that was put out. I had my phone rooted and apps frozen and whatnot, but I wasn't thinking and went ahead with the OTA update. I was reading that a lot of people had this break their root, but mine seemed intact because I still had the SuperUser icon, I can still do a nandroid backup etc. Then I tried to go into TitaniumBackup and it told me it can't give root access to the app. I went into BusyBox and it too told me that it couldn't gain root access, and to go into SuperUser and disable/re-enable it. I tried that and it did nothing.
I guess what I'm asking about the root issue is what would cause this, and am I truly rooted? My screenshot app still works, I can make nandoid backups, so I would say it is rooted, but why did my other stuff stop being able to gain root?
