Great work so far, the only issue I seemed to have was with saved wifi networks. It occasionally would disconnect and then on trying to reconnect it would simply hang at saying saved network and when I would press the network to connect it wouldn't even try to connect.This would go on for some time even after toggling wifi and airplane mode. In most cases it would eventually reconnect on its own but it seemed like it could be an issue for some.
Had this happen to me earlier, but it went a bit further. Seems like after the device has been on for a while (8+ hours? not sure yet), the Wi-Fi decides it doesn't want to connect to saved networks anymore. It seems like it kept trying to connect though, as during that period the phone got pretty warm and the battery started draining pretty quick. I had to reboot it to get everything back to normal.
If I can get it to happen again and I am in a place to gather logs and whatnot, I will try.
