1. Run a phone virus scan – which can easily be found on Google Play. There are numerous apps that can help you to scan viruses and get rid of them and they are easily installed.
2. You can also manually uninstall malicious apps. The safe mode on Android turns off the access of all third-party apps to stop them from running. It is a great tool to find a reason for your phone’s unusual behavior.
If the problem goes away in the safe mode, you know that you are dealing with a virus. Most Androids will Reboot to Safe Mode after holding the Power off button, while some of them require a bit more complicated process. However, if you do it correctly you should see the ‘safe mode’ words at the bottom of your phone screen.
3. You can download an app that will keep your phone protected and optimized at all times. It will automatically run the cleaning and check-ups and you will get notified whether is your phone clean or not.
