Unresponsive to touches and blank screen after dropped
I dropped my Note 4. Now screen is blank and doesn't respond to touches. I have display on HDMI. But because it is locked, I cannot enter any PIN. If I remove the SIM card, then McAfee security locks the phone and waits for an other PIN. If I connect to the PC and run Smart Switch, it says the connection mode should be MTP. I thought using a mouse, but I haven't bought a Bluetooth mouse yet and I cannot enter a PIN on HDMI to turn on the Bluetooth. Also I have Mobizen app but it says I have to update it on the phone. I want to try soft reset, but I don't want to loose my stuff. Does soft reset is a factory reset? I looked at the questions and comments on this site and saw two ways to reset: remove battery, wait 1 min pressing power button; and pressing home and power button 10 sec together. Which one is true?
