Samsung a20 corrupt boot up file

Is there a way to repair or remove a bad file in the bootup screen. I have reset and hard reset my phone four times. It says my sim card has no data. Restore files aren't working right. At one point it said their were 8 users on my phone. Wifi list showed all users were connected to my phone...it turns wifi and wifi calling, bluetooth on all by itself. The phones history is no place I've been. It tried to log into my bank info over and over...changed every password I had. Finally this morning  it locked me out of the phone all together. I tried putting the first rbackup in the samsung cloud but it fails..doesnt matter Google takes over without even logging in to anything google... I'm at a loss

Re: Samsung a20 corrupt boot up file

I would like to look into this issue for you. Let's look into a couple of things first.

  1. Did you try with the previous person mentioned?
  2. What are you symptoms exactly?
  3. Have you tried clearing the cache partition on your phone? 
  • Turn off the device.
  • Press and hold the Volume Up key and the Bixby / Power key.
  • When the Android logo displays, release both keys.
  • An 'Installing system update' message may show briefly before the Android Recovery menu options appear.
  • Press the Volume down key several times to highlight Wipe cache partition.
  • Press Bixby / Power key to select.
  • Press the Volume down key to highlight Yes, then press the Bixby / Power key to select.
  • When the process is complete, Reboot system now is highlighted.
  • Press the Bixby / Power key to restart the device.
