Hi,
My device is Xiaomi Redmi Note 4, Version of Avast is 6.10.4
After installing Avast fingerprint reader in my phone started work oddly. Sometimes it reads my fingerprint correctly but sometimes it only turns on lock screen. I tried uninstall Avast and the problem disappears, but when I installed program again it returns.
I have also problem with advanced web-defence. Avast keeps saying that it’s off even I have done what istruction had said.
