the best thing to do if you have a Q+ box is to either flash it with a older firmware like i have which is the Sunvell Q+ 1.1.5.img android 8.1 which does not have the 720p bug' but you do lose the remote control function (best to use a air mouse remote anyways) or the best custom firmware i have found for this box is called T95 MAX-SCV2.img which is very stable from Beny.
Also using t95 max svc2 image from beny, great rom, just update nova launcher and install bromite system webview etc and it's a great rom
My box aeromedia nanomax 4/64gb which is a Chinese clone of the t95 max.
I downgraded from android 9 to this svc2 nougat rom from 4pda..... Lost a gb of ram but who cares. Box runs like a dream now, added active cooling (raspberry pi fan) and i wouldn't swap it for the world now :laugh::good:
