I did the update to Android 8 using "Local update" method, followed by a factory reset (Android didn't manage to load without it).
Unfortunately, I noticed fast charging isn't working at all (I tried multiple times).
Without fast charging it takes ages to fully charge the phone.
Could you please solve this issue with a high priority, as soon as possible?
Fast charging is really vital to me and I wouldn't like having to downgrade to Android 7.
I'm a software developer, see my projects
if you're interested.
