I have a Huawei P20 phone. I have installed Ad-on for Huawei and also Mobile 1 add-on, but i can not use teamviewer quick-support.
Huawei's P20 Pro is one of the most powerful Android phones you can get right now. It also doesn't support expandable storage or have a headphone jack. Your browser does not currently recognize any of the video formats available mykfcexperience.
Acording to apk.cafe and other resources, the P20 is fully supported after version TEAMVIEWER QUICKSUPPORT 15.2.41.
Did you tried it?
