Smartphones have useful features that many do not even know exist. Associate Professor Evgeny Kashkin spoke regarding them.
One such feature is the operation of Android smartphones in “safe mode”, which can help if the phone has become infected with a virus or frozen. If the phone boots in this mode, all third-party applications stop working.
