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.
There are also combinations of secret codes, thanks to which you can learn a lot regarding the gadget. So, the key combination * # 06 # will allow you to find out the unique identification number of the device.
