I recently upgraded the firmware on my Note (Build # 2019-06-13_12-37_2.1.2_23f6dab) and now whenever wifi is enabled the tablet freezes. Trying to reboot fails repeatedly until I plug it in to the charger, then it works fine both with wifi and without (as long as it is plugged in). Therefore it seems to be related to power consumption, but it happens even with a nearly full battery so I suspect it may have something to do with the way that the new firmware tries to optimize battery use. If I do not turn on wifi I have no trouble using aps like Libby, reading and annotating PDFs, or editing notes. Switching off the “power saving mode” does not help.
Others have posted somewhat similar problems and there has been some discussion related to battery failure. I purchased this tablet in June 2018, so I would have expected the battery to have lasted much longer. Also, I do not think I can rule out some problem with the firmware. However, if it is the battery, what are my options for getting back to normal operation? Is it possible to purchase a battery and replace it myself or do I have to ship it in for service? If it requires shipping, what is the cost and turnaround time (I use it daily for work).
I really love my Boox Note and would be very discouraged if I found out that after spending so much on it that I have to replace the battery every year.
