Hello,

I have a trojan detected in com.android.tools.callassistant, which even stayed resistant after setting back to factory defaults.

What else can I do ?

OK,

Looks that I managed myself.

For that, I rooted my phone with kingroot, removed the trojan with stubborn trojan killer, and that it.

PS: my phone is a Omega Pro, Android 5.1

I rooted also the device. This time it was Blackview A8 Y806. After flashing with TWRP Recovery the trojan has been removed. Thanfully the process of rooting is simple.
