Review from Wally Hale
Used this for years, unfortunately on Pixel and Android 8, I get regular crashes now. Can crash randomly in background, or more annoyingly, when composing an email and you lose it!
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.
This is a good clean mail client with no ads and no unnecessary perms. HOWEVER, it appears to have a major functional deficiency. It seems that it is poorly integrated with contacts and it cannot acquire/learn new addresses that are directly entered into the "to" field of a new email or email reply. It neither stores them in a local internal address book nor offers to add them to contacts. This is a very undesirable behaviour / deficiency. The app also appears to lack any mechanism for managing spam, i.e.,way to add addresses to a spam filter. There is also a problem with the way it parses and delimits manually entered email addresses.
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.
Been using K-9 Mail on my phones since my first Android. Brilliant email app, does everything I need flawlessly. Have to agree with all the other users complaining about the new icon though... it is truly truly awful (Sorry to the dev who designed it!). Any chance we can go back to the old, better-looking icon? Other than that, 5/5, would highly recommend (and often do).
I've been using this app for years, always steadily improving upon an already great app.... but what the heck is with the new icon?! Please, I join with many in asking "Please switch back to the old one!" [Edit] Still a great app, but the icon still hasn't been changed back. Looks like something K-9 actually threw up. When people complain about an icon enough that some are considering uninstalling what does that tell you? lol
Push mail has not been working reliably for years, always leading to the error message "Syncing disabled" and tp delayed incoming mail. Why K-9 disables syncing remains unclear. Other email clients, like Thunderbird, do not have any such problem. K-9 also has too many, too complicated settings and some user interface problems. Apart from these problems it is good.
- Fixed bug that caused 'Quiet Time' to behave erratically
