I'm not sure if it's a software problem or a hardware problem that's not the motherboard.
This is my phone's original stats, as I have written down.
N7105
ROM: DN3 v3.2
kernal: AGNi v3.9
bootloader: 4.1.2
Recovery: Philz 6.07.9
The problem is that the phone just randomly stopped waking from sleep. Not all the time, but it just started one day and slowly increased in frequency. I eventually figured out that the phone was simply not waking up, causing the phone to (presumably) freak out, because if the freeze happened hours ago, then the phone would be very warm when I picked it up and, after forcibly rebooting via the power button, the battery would be way down.
I noticed IndexServices was using a lot of battery power, and google tells me that it freaks out at files over 200mb in size, but best I can tell, I have no such files. I can't recall anything that would change this when the freezes started happening. It may not be relevant at all.
I could live with the forced reboot for a while, but having my battery capacity killed for no reason sucked.
Screw this, I thought, I have a spare motherboard, I'll figure out the problem later or never.
Nope.
My phone's current stats.
SGH-t889
ROM: DN3 5v2 final slim
kernal: default
bootloader: 4.1.2
Recovery: TWRP 2.8.0.0
I swapped the motherboard in and used Titanium to restore my most-used apps and their data. Unfortunately, the problem seemed to have followed the change, although in a different way. The phone just freezes and doesn't accept any kind of input- no touch, no buttons, nothing. I have to pull the battery to reboot. It doesn't just happen when asleep. I've had the phone literally just stop responding as I was scrolling through a webpage. It seems to happen mostly at night and early morning, which is no bueno. I can't use it as an alarm anymore. But it's still better than leaving it alone only to find the battery down 40%.
It also occasionally reboots on its own. I haven't found a pattern to any of these problems.
I played with this motherboard when installing the ROM and such and never had the above problems, so it may or may not be related to the problem I had with the other motherboard.
It's not my SD card. I pulled it when I still had the N7105 motherboard in. It didn't make much of a difference.
I installed SysLog and got a bunch of logs from the N7105 motherboard right after one freeze/reboot. But I'm not entirely sure what I'm looking at nor what to look for. It's been a while since I've fiddled with my phones, so I'm not very enthused at the idea of reflashing my phone.
What can I do to better pin down the root of the problem, short of reflashing everything and hoping the problem goes away?
