After a successful clean install, three points come to the fore:
IMEI present
MAC adress: 00-a0-c6-eb-5c-d8 problem …
BlissLauncher 3.0.1-beta crashes at the first opportunity and is practically non-functional. A window constantly pops up and indicates that the BlissLauncher app has been terminated. I had to deactivate the BlissLauncher in order to get some peace and quiet into the system.
I have tried several alternative launchers, including Lawnchair, but - compared to a working BlissLauncher, all other Android launchers on a tablet are not a good alternative and only stopgap solutions.
