I have a M3 note L91 version and I have upgraded to lastest 6.1.0.0 stable. At first, every function worked perfectly fine, but after few charged session, gesture wake up function didn't work anymore. I tried to factory reset and gesture wake up function work again and again, it didn't work again after few hours.
Is that hardware or firmware problem? I cannot figure out the reason. Is there anyone here also got the same problem with me?
