OK Kernel V8.2
So I've came across a few issues such as random reboots, crashes, hangs. All of those should be gone now, on top of that camera should work much better, less buggy and faster.
With this release the worst issues such as freezes while waking up the phone or turning on the camera should be gone. Some of those even go as far as doing better what sony did with camera. This release is mostly bufixing, but with less bugs there's faster phone and better battery.

sdcards should also work better, if you're using sandisk sdcard and had any issues, there will be none with this kernel, hopefully.

If anybody will get a random reboot or crash then please get me last_kmsg

You can always just open file manager, go to /proc/ and copy last_kmsg from there anywhere else and upload it for me. I'll make sure to fix the issue.
What to keep an eye on:
idle temps
wifi
sdcard performance/reliability
camera - all of it
Gaming performance/temparature
random reboots
This version isn't rock stable, it's quite experimental, but I decided not to just test it myself, but give it out to all of you to test it.

All in all, I expect it to be the best, most stable and perfect version yet, but i can't guarantee. Don't worry tho, I never do something that can damage your device, but it's always on your own risk.
