Redarding AOD I though the fix Fairphone provided will be included into LineageOS and so in iodéOS as well? Like posted by you in the outher thread @rlees85 → [FP5] Always-On Display issue (pixels not black) fixed in iodéOS? - #3 by rlees85
Apart from that, my FP5 battery life is okayish with iodéOS.
I discovered a little strange issue since 6.x, that the tiles in quick settings are German (as well as the responses in the lock-screen like “Zeichne das Muster” [I use a pattern]) even my device configured to English. I can put German up in the settings and then English again and all settings are English again, but it does not stay like this. No clue why.
