[OnePlus 2 Q&A, Help & Troubleshooting] djc82k:
Dear All

Since long i use my op2 only anymore as a navigation system, since i use my P20 - however, thats not the problem.

My Problem is that the Wifi and the following hotspot function is not more working.

Since i am having only less knowledge about android but a generell understanding about linux, thats how i got the debug output of dmesg:

I used this to fetch the log

dmesg -w | grep -Ev 'healthd|smbchg|mdss' > wifi.log

Output Log
