I have bv 8000 pro with latest firmware , start to straggle with my calls quality, i have 4g network with LTE services on but when i starting calling it goes straightaway down to network position E or G and each time i call is very bad reception in other side, no one could hear me properly, most likely in landlines or it cutting off , sometimes people saying they could hear them self via my phone as looks like loud seeker on, if i talking more then 20min phone goes crazy with network bar goes up as in full range and after goes down as,, E ,, from 4G very fast and affecting call quality i live in Uk , is any chance to improve reception or do something about?
i try go to battery and mark phone app as not being optimized, but same problem appears.
Before i had Blackview 6000 it was hd call option with this phone i never had any calling problems. with new on bv 8000 pro cant have normal conversation , via phone app, or Bluetooth etc.
Please advice .
