USB driver errors we may encounter including “USB device not recognized”, “USB driver failed to installed”, “MTP USB device driver failed” etc.
Here we provide a few options to fix the problem of Android USB driver.
Before we get started, check if USB port damaged to exclude the hardware issues. When computer reboots, the Android USB driver will be reinstalled.
Try the android device in another USB cable/port to check if the outcome is the same. Click next to “Universal Serial Bus Controllers” and right click on the Android device driver and tap “uninstall”. Many android phones (Android 4.0 or later) like Samsung S4/S5/Note 4, HTC One M7/M8, Sony, Motorola etc. If MTP USB driver failed to install, you are not allowed to transfer media files from/to android devices.
One way to prevent this would be to archive older messages off using Outlook's archiving functionality.
Also as a preventative measure you might choose to go to your advanced settings and select a shorter period to sync (for instance, if you have all days of email and appointments set to sync, you would be much better off to sync 1-2 weeks of mail instead, and also perhaps 1-2 months of appointments).
It’s better that you have someone do it for you; someone more knowledgeable in flashing firmware on an Android phone but still nothing is guaranteed here. If you also call Samsung or Google, you’ll be asked to verify the Google account, which you can’t because you don’t know the password in the first place.
Q: “After upgrade to Android 6.0.1 my email messages continue to accumulate; i.e., I delete emails from the server only when I have read them on my desktop computer.

Step 3: You need to do the master reset to delete system data, settings, apps, etc. This is where I screwed up I used Smart Switch to update it to Marshmallow.
It will bring the phone back to its factory default settings. I had made a new Google account and I have no idea what the password is. I also tried the OTG cable method with the unlock file on it but nothing happened when I did that.
