I am using MAX PRO M2 device, currently running on 'Android 10 beta 2'.... it is nearly gone 3 months im using this Beta 2 version.... i had some major issues with this updates...
1 . WIFI connectivity - the devices connection losts several times for no reason, even though i have speedy internet connection wifi...
2 . The Mobile Network- the network reception of device is very poor with numerous company sim card i tried...
3 . The Speaker Output is very low (if the device is in pocket i cannot hear the phone ringing, this is annoying)
4 . The battery backup is all good, but it must be more better....
for all these bugs to be resolved, im waiting for the 'STABLE VERSION of ANDROID 10' For 'MAX PRO M2' device....
( currently running on Android 10 Beta 2) Thnk U.
