How Do I change from PTP to MTP mode? Cannot find options in settings That may be the issue why I can't see my captured videos from my phone when connected to my pc. How do I access PTP and MTP modes? Can't see any options in settings.
You can do that via adb or a terminal app (in the latter case, ommit the leading adb shell from the examples):


read settings: adb shell getprop sys.usb.config
find valid settings: adb shell grep usb.config= /init*rc
change settings: setprop with the appropriate values (e.g. adb shell setprop sys.usb.config "mtp,adb" or adb shell setprop sys.usb.config "ptp,adb")


EDIT: If the above doesn't yield the expected results, it might need root powers. So if your device is rooted, you could try to run adb root prior to above commands. If your device does not accept this ("not available in production builds"), instead run:

PC&gt; adb shell
Android $ su
Android #


Now at the root prompt (#), run above commands without the adb shell prefix (e.g. simply setprop sys.usb.config "mtp,adb").
