So I have this phone that I bought at the start of 2013 and it worked just fine. Earlier this year I got myself an iphone and I gave the S3 to my grandmother--her first introduction to smartphones.
Well, shortly after I gave it to her she was apparently having a problem with the charging port not working so she took it to a repairman. I don't really know what he did, but I guess he replaced the entire motherboard. My grandmother showed it to me and I had to set it up from a factory reset. Now when you boot it up, on the screen with the 'samsung' logo, it shows an unlocked padlock and the word 'custom' underneath. I assume this means it's rooted? I don't know. All I can tell is that it's running Android 4.3.
Anyway, now it's having various problems that it's never had before. There is a software update available and a message comes up several times a day saying that it needs to be installed. But it won't work. When I try to install it, it reboots and then a message pops up saying that something went wrong. I'd be just as happy to not install it and disable the notices, but I can't figure out how to do it.
The other problem is that there's a message that frequently pops up saying that the wifi connection is unstable and it cannot connect. This is on the home network--I don't believe my grandmother ever tries to connect anywhere else. But I know there's nothing wrong with the wifi itself because there's like 8 other devices in the house that work just fine.
I have no idea how to fix either of these problems, but unfortunately my grandmother gets annoyed when I tell her as much. Are there any ideas on what's wrong? I have a feeling it stems from it being rooted, but I don't know a thing about that. I've never tried to root any of my phones.
