Yes. It almost sounds like there is something on the phone that shouldn't be there, or an app that shouldn't be acting like it is. You might want to try starting the phone in "Safe Mode" and see if the problem still happens. If it doesn't, then you definitely have something app or otherwise, on the device that is interfering.
To get into "Safe Mode" please do the following.
1. First turn off the phone.
2. Next press and hold "Power" until you see the manufacturers logo on the screen, then release the power button.
3. "Quickly" press "Volume Down" and hold it for few seconds until you see the message "Safe mode: ON" or something similar.
4. If you wanted disable it, simply repeat the steps above, and you should see "Safe Mode: OFF" rather than on.
