FAQ

Reporting Bugs
DO NOT Report bugs if you're running a custom kernel or you installed Xposed
Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)
If it is a random reboot, grab /proc/last_kmsg. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
If the problem disappears after running "setenforce 0" from a root shell, grab /data/misc/audit/audit.log

Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. Please also do not report known issues. Any bug not reported in the bug report format below may be ignored.

[Lenny Bard]

I just installed it on G980F, no major bug, no lags, only fingerprint enrollment doesn't work very well but I think you already know that.
Many thanks to the devs, you're the best !

Not offically yet, some users said its working, also there are new device trees on the git for the non G980F models, so it might be coming soon.

How did it go? I'm curious for my sm-g988b

How did it go? I'm curious for my sm-g988b

working fine for me on sm-g981b, just no 5g, i dont really mind tho, it chugged battery anyway

 

[1Michael23]

By the way guys, the solution for fingerprint enrollment is to tap very quickly at first until you get to the next screen, and then scan as normal

 

[UdirGa]

Stuck in a boot loop / first boot taking painfully long, going on 6 hours.

Anyone else experience that too?
