Mine is running sice Nov. 2016.
But I’m not happy with it anymore. It has too many issues I could not solve.
I tried a new battery - did not help.
I tried power managers - did not help.
I tried a factory reset - did not help.
I tried new installation of Android 9 - fastboot did not run.
Issues:
Random reboots (5-10 per day).
Battery empty over night - never holds a hole day.
Apps crashes somethimes.
Loses Wifi and has a bad telephone connetion.
Screen black during/afters calls.
Reboots while charging.
