Finally got mine Q80 and I love it. I'm getting more than usual noise from the speaker though, clearly caused by display PWM. It changes with brightness settings, but never really goes away.
I found the same problem existed on the first PocketGo, and it also exists on PocketGo 2 (which is no surprise, as Q80 is clone). I even found fix for PocketGo 1, in form of script changing display PWM frequency, and people seemed happy with it.
Anyone knows about solution ? I'm also thinking about hardware solution, imho low pass filter should fix it, it well selected capacitor across the speaker.
