Since the 6.01 Marshmallow roll-out on T-Mobile, both our families Galaxy Note 4's have begun to act crazy. These issuess started on both phones almost simultaneously - within 48 hrs.
1.) Phones began shutting off at 25-30% and entering a continuous reboot cycle. This lasted a week, now it doesn't enter endless reboot, it just dies. Putting on the charger it will start around 5-10%, then immediately jump back up around where it was (25-30%).
2.) SD card is not supported. I've read this was due to file system change on 6.01 making the SD Card appear corrupted. I cannot even find the SD card thru the UI anymore to try re-format - it's there for the error, but not recognized in Storage.
3.) Waking the phone up from a black screen takes 5-10 seconds after hitting the button. This is sometimes reduced if you catch it immediately after shutting off, but if you wait more than a few seconds, your forced to wait for it to 'wake up'.
I have tried a factory reset thru the Marshmallow UI and 2x by holding the power/vol.up/menu button and doing the factory reset that way - always the same results in the end.
Is there a way to roll-back the Android version to Lollipop? I've browsed the forums for previous answers, seems a number of people have the same issue but no resolution from T-Mobile.
Anybody have an answer yet to these issues or know how to roll-back to Lollipop?
Even this forum does not have troubleshooting for 6.01 - they only go up to Lollipop.
