Crash happens always. Steps to reproduce:

1. Open the app.
2. Click on any of the entries of email list to display it.
3. Use either system back gesture/button or click the ui back botton at top left of the activity intending to return to the email list view. App crashes immediately.

Crash trace as attachment below.

Did not register a fc, but I can reproduce the "back gesture" in any mail will close the application.

Thanks for the report. It's an unpatched Android bug in the OpenGL rendering path: the fade animation on opening/closing a message composites the WebView offscreen, and on GL-rendered devices the system renderer hits a null pointer there. Recent Pixels render with Vulkan and are immune, which is why it slipped through my own testing.

Attached is a test build with a fix, plus a safety net: if a device still manages to crash once, the fade is permanently disabled on that device instead of crashing again. Could you try it on your OnePlus 5T? Opening a few mails and going back each time is the crashing path.

Note: it installs over your current version and keeps your account (same signing key, works over the F-Droid build too). It carries a temporary high version number though, so once a fixed release is out you'll need to uninstall it and reinstall from F-Droid to get back on regular updates.
