change the Android app so the standard keyboard makes suggestions and autocorrection.
As my sister told me, the standard keyboard on her HTC phone does neither offer suggestions nor does it autocorrect during input in the Tutanota Android app. However, I do not have that problem with Swiftkey or Minuum. But that problem should be fixed as it makes typing a pain.

I can confirm that for the AOSP keyboard that this is not an issue.
