Hi guys,
I have been using Harmony OS 3.0 in my smartphone for a few months.
Here are my experiences :
1. This is just another custom ROM without google app and services
2. All of my apps created with B4A runs fine
I can live without any Google apps, Huawei's App Gallery provided enough apps for my need.
You can choose who is spying on you, google or chinese, for now I choose the later, at least they are not massive as google right now.
Yesterday, my other Android phone suddenly has Android System SafetyCore app installed, uninstalled it immediately.
