I've bought a GPD Q9 from GeekBuying (delivered to Chile) and I don't understand the difference between "batch" or "firmware"
Is not the same, right?
I don't know the difference about the GPD Q9 and his new version. New Hardware?
Different batch is the same device with a different thing. In this case Analog has been changed in q9, so consider it a new device, becaue it uses a different firmware.
If you are not sure which device you have, just go to settings/about device and check the build number.
If it says Q9 it's a standard Q9, the old one, if it says Q9PSV then it's the new one with different analogs and different firmware.
