Overall this rom is awesome.
But I think it could be improved.

This is a bug that I encountered in Reddit app. When I click on the picture, instead of showing the whole thing, the picture actually zoomed out.

I think it has to do with the Screen Size & Screen Density.
(I purposely changed my Screen Resolution)
But I don't know how to change the others.

Oh and adaptive charging didn't work.
I set it to stop charging at 90% battery but it didn't stop.

I'm experiencing issues with charging. When i tap the screen on, the rapid charge falls to charging ... I don't think the charging is as good as miui ... Thoughts ?
Hi @guitarbite, apologies for the delay on my reply. Would you kindly provide logs for this?, and thank your very much for your feedback. Btw, regarding reddit issue, must be an app issue related to your resolution/dpi.

Best regards,

I have version 4.16.
Is it possible to set options for reboot e.g. recovery, fastboot, or restart the phone ?
