Recurring Malware! Help no solution!

[Rscx]

Hi All..
Im having a huge problem with a recurring malware or virus on my samsung galaxy s5. The following are things i have experienced:

*making random calls on viber and normal cell phone.
*picking up calls randomly
*googling random people on facebook with random messages
*sending random messages on viber
*changing phone settings vibrate to sound. Changing automatically of battery percentage icon on and off.

Etc

I have done a factory reset. I have taken it to a samsung certified technician. I have even got a brand new replacement samsung s5. But this problem still exists. Can someone please help me. Im very desperate for a solution!

Welcome to Android Forums.

Did you try running in Safe Mode disabling all apps you installed without uninstalling them? If the problem stops it is caused by an app that you added. Determine which one and uninstall it.
