Hi
I have got a Pipo M9 pro 3G and I have some trouble with the screen brightness.
Sometimes the brightness automatically goes to the maximum. So I try to reduce the brightness in the settings panel but whatever the position of the slider is, the brightness is still very high (at the maximum I think). Sometimes it toggles between the actual setting and the maximum setting. I precise that I am not in auto mode and I have no apps or widget to set the brightness (Actually I deleted everything that can interfere with the setting).
Someone has the same behaviour or an idea ?
Regards.

Hi
Actually it is a hardware issue.
I opened the tablet. When I pressed on the screen PCB the issue is more frequent. So I removed the kapton adhesive tape and found the led backlight PWM controller was badly soldered. I re-soldered it and now the brightness setting is working very well !
I hope it will help.
Regards.

Even on lowest brightness, the slider is on 20% and screen is still bright for me subjectively speaking. If I try moving slider to the most left side, the brightness stays same and is not getting dimmer. Look on this picture and you will see that I moved slider to its most left where typically screen should be almost dark but it is still bright in my case:
I also think that is the reason my battery lasts less than it should normally. I did not update firmware that my tablet came with but if I do, whether it will fix brightness issue.
