Review from A Google User
Used to be the best mail app I used but it's quite buggy with Android 6+... Major bug is syncing is erratic - sometimes works, sometimes doesn't unless you disable battery optimisation for the app to exempt it from Doze. Minor bug is sometimes old read emails gets marked as unread. Some aesthetic update wouldn't hurt like some icons.
Installed on my s7 Samsung edge, works well but will not poll automatically, says syncing disabled ????? Not sure why they can not fix it. I filed a trouble ticket online but it was ignored. My guess is they can not figure out the syncing disabled problem. JUST FOUND A POSIBLE FIX ON FORUMS. TRYING NOW .....
Puerile icon. Sync issues- force close and restart app and sync starts to work- until it falls over again. This sync issue has been going on for well over a year now, no idea how long. After a while it starts to eat away at you. I'll give it another couple of months and then another star's going. Trouble is- what alternatives exist? I came back to K9 when K10 ceased to be supported. No one listened there either.
K-9 Mail is having trouble when OpenVPN connect is activated. All other apps and web sites work fine. Even when the VPN is then disconnected on LTE the problem persists. Moving next back to WiFi the problem still persists as well. Only a reboot of the phone seems to help.
I have been using this app for several years and whilst it was good to start with, it's been going rapidly downhill. It's constantly returned server authentication errors, despite the fact the settings are correct and that I'm not having these issues with other apps. I am currently using Gmail as a backup. Chances are, I may look for another email client.
Actually, it is a very good email app. The new icon totally sucks and the main developer seems to be completely deaf to users feedback about it. Don't be fooled by the icons you see on the Google play page for k9. It isn't showing the new icon. Even if the old icon doesn't come back, the icon needs a different look from what it is now.
Update to original review... still stalls and then just sits and chews on data, with the little working arrow spinning at the top of the screen until I force stop the app!! Cmon guys, fix the bug already!!! Have used k9 for years, after updating last time it has started stalling, with the polling circle running nonstop until I force stop it, which has also caused data usage to skyrocket... just installed new update, hopefully will fix issue
- Fixed bug that caused 'Quiet Time' to behave erratically
