Question: This application is sending a lot of spam to my phone recently, two or three times a day. I deactivated broadcast messages, tried converting USSD pop-ups into notifications to avoid being interrupted (didn't work). Basically, everything I tried didn't work, so now I want to remove it from my phone. Is it possible to do it without root, with ADB or something? I'm not a power user but I have used ADB to give permissions to some apps before.

Answer: 
1. Connect Your Phone to PC Using Data Cable.
2. Turn on USB Debugging
3. Setup ADB Connection
4. Type 

```
adb shell

```
5. Hit Enter and type again this

```
pm uninstall -k --user 0 com.android.stk

```

or 

```
pm uninstall -k --user 0 com.android.stk2

```
