Same here. Nothing will stop this
pioce.com nightmare, even restore. Pioce will appears again as soon is possible. Pioce is a present from Leagoo, it is malware and we must clean it. My phone is leagoo elite 5 and I have two same devices in my home with the same problem.
I think that I found the solution! Now my phone is clean (I hope for ever). Pioce.com is hiding on leagoo launcher. What you can do?
1. Install Sophos Security (
https://play.google.com/store/apps/details?id=com.sophos.smsec). You will see there all the problems and you can delete many of them, but not all if your phone is not root. Disable all these apps from the settings/apps/all. Unistall programs with chineze letters. Beauty MakeUp it is a nice program but not safety.
2. Clean cache, history, cookies etc (settings/apps/all): a) Leagoo launcher and b) Browser that you use (mine is UC Browser), c) all leagoo apps
3. If pioce is still there, then you can change launcher (nova is nice) and browsers will be clean. You can test this, if you run your browser from leagoo launcher and after from nova (or else).
4. There are two "clean" browsers: CM Browser ...sorry, I don't remember the other one. Pioce.com doesn't run there!
5. For more security, block
pioce.com in your router's firewall.
Good luck
