Experience with recent upgrade 15.1 -> 16.0
Following instructions https://wiki.lineageos.org/devices/FP2/upgrade
- lineage-16.0-20190601-nightly-FP2-signed.zip
- no microG, no adonsu, no encryption
- TWRP 3.2.3, no wipes
Absolutely painless!
All data, apps, configs retained.
Great work! Kudos to @chrmhoffmann !
Remarks
- dual-sim works fine, no other ‘special’ use case
- Further updates (nightlys) - TWRP/Reboot now works directly (15.1 had to be done manually)
Observations
-
On reboots battery level sometimes displayed wrongly (~20% too low)
Remaining capacity shown correctly only after full shutdown

-
Volume control doesn’t work with phone (neither buttons nor headset)
Constant volume level even if slider is at max or down at 0.
Works fine with music player, though
