For Polish (on computers) we have a keyboard layout called "polish programmer" widely adopted many years ago affectively making the original "polish typewriter" layout (that mapped diacritics to separate keys) almost extinct. For typing diacritics AltGr is used (eg. ą = AltGr+a). Typing without diacritics is considered clumsy at least within the groups of people I interact with. On mobile it is a bit more relaxed, but the dictionary autocorrection is sort of OK. Conjugation, declension etc. complicates things, but you have the stem + most common suffix autocorrected, so usually it is a matter of erasing last 1-2 letters and changing them if needed. Also the Markov chain alike logic of autosuggestion quite often is right with the inflection.
