I have an LG G4 that bootlooped so I sent it to Futuretel. I'm not going to put them down when it comes to the speed of their service since my phone was sent back to me that week but due to the shipping company being lazy I didn't get it back until about three weeks.
The real issue is that after I got it back I noticed that my phone was being weird. Every day it just got worse. I have been using it normally, the way I would use it before it bootlooped. Lately it's been dying in just an hour, two if I'm lucky. On top of that It overheats like crazy. I don't mean warm, I mean literally so hot that it's uncomfortable to hold. Now I'm constantly paranoid that it's gonna bootloop again.

Overall I'm really angry about this. Now I have to get a new phone because I can't even stand this phone anymore. Yeah, be careful everyone.
