This is a great security app and I have the desktop version for my PC. The only reason I haven't given it a full 5 stars is because the little always on widget that sticks to the edge of the screen is highly irritating and sometimes interferes with the way my phone screen reacts to touch input. Allow us to remove the obstructive widget and the rating will go up, status bar icon is quite enough to allow easy main app access.

Hello Kitala and thanks for taking your time. You may have enabled the shortcut option in the Accessibility settings. Make sure to put it back. If that doesn't help, please reach out at android@avast.com. David

Hi Steve, it seems some app keeps killing Avast running in the background. You can check https://dontkillmyapp.com, which is a nice summary of how various manufacturers use optimizing features. I hope it helps, David*Avast

Update. Still 5 stars but since I have reinstalled Avast again I am having problems saying the app is malfunctioning and is not working. At the end of my last subscription I had this so much it felt the same as not being protected at all. I really like this app. I went to my phone carrier and they could not find anything inferring. Help!!!! Also only one more feature would make this an absolute must have...... Taking a picture when someone tries unlocking/ snooping on devices. Is it possible?
