I use a compact mode in AnySoftKeyboard, which might work well for tiny screens! The keyboard is only 5 keys wide, and most keys have two corresponding letters (double tapping to type those letters). It is quite nice even on normal sized phones for individuals who are prone to mis-tapping resulting in typos like myself, I recommend giving it a try.

the biggest bull of the expenses probably comes from the way the manufacturing and materials are checked.

Could you expand on this? I am unfamiliar with Fairphone’s methods for determining and checking sources for materials and manufacturing. Is it flawed?
