I use K9 only on my vacation phone and i transferred the version which i had on Android 2.1 again and again to the next phone. its version 4.400.
this version runs fine on Android 4.1, but when i migrate to next phone (Xperia) with Android 6, k9 crashes always when select emails (eg. for delete). Only the screen with the email list disappears, and an crash error pops um, then i see the screen for selecting folders.
actually i like this small and fast version and dont want to go the the newest one. the new interface is too much gmail lookalike
i checked on another Android 6 phone (Honor), and here is the same behavior.
i just found in github:
K-9 Mail v5.003 (stable)
- Fixed crash when selecting multiple messages on Android 5.1
so i just have to try 5.003 ?
