So got my hands on that phone and it's just a piece of delicious cake (figuratively ofcourse). But i have a small problem with connecting it to my PC wich runs under Windows 10. There was one odd thing when i first connected it. At first a chose it as MTP, emmideately after it has instaled drivers and phone became visible on "My computer" i gone to internal storage and started copying some music from PC to phone, all was fine until i got an error message on PC that was telling something about that "device is used by another process" or something similar, i didnt payed attention to it. Then the phone was gone from "My computer". I gone to the device manager in Windows and saw that there was an "unidentified device" amongst all others. I switched USB connection to PTP on phone and it was shown again but as "camera". So i want to ask how to resolve this little issue and what is actual diffirence between PTP and MTP connection types.
P.S. I had tried to connect it to my wife's laptop and had the same results on it but without doing anything. I had patiently waited for it to install everything.
