I have the P30 Pro, VOG-AL10, 8GB/512GB model; gifted from a friend
I have a couple annoyances
1) My biggest problem (along with any other mainland Android phone I've owned) is there is no way to force full encryption. You can only add stuff to the "safe."
2) My second annoyance is the aggressive power management. I've done a lot of my own tweaking so it doesn't force close my Cisco AnyConnect client for example. I use LastPass for password management and for whatever reason, whenever I re-open the app it requires I use my 2FA again even when I choose remember for 30 days. I don't know if this is a LastPass problem or what. The only way to keep it from resetting is to keep it active in my open apps.
3) Even though I use Chrome as the default browser, for certain tasks (like using a WiFi hotspot that requires registration), it will still open in the default browser which you need to accept their TOS to use...
4) I use SwiftKeys as my default keyboard. I have the Huawei IME unchecked. I use the phone, after a while the Huawei IME will get enabled again.
