I recently bought and have been using the Huwawei P20 Pro. As a longtime iPhone user, I am actually enjoying the phone, especially the camera, very much. I also think the Android operating system has some advantages over IOS and understand why people love it. That being said, however, I have been having problems with several apps that either don't function or have stopped working altogether. For example, the NBA app was working fine for a few days, then started crashing upon opening. After uninstalling and re-installing, it still wouldn't work. I then did a factory reset and re-installed it. It worked fine for a few days, then mysteriously started crashing again. Everyone else I know with Android phones has no problem with the app. Another app, iWatermark+ will not run properly on the phone. It opens but then doesn't function as it should. Again, i un-installed it, then re-installed it and it still wouldn't work. Again, other people I know with Android phones have no problem with iWarermark or iWatermark+. This has now led me to the conclusion that there's something wrong with the phone and not the apps. Because of this, I don't really trust using the phone. Any ideas or suggestions would be appreciated. Thanks very much.
