The most mentioned feedback item over the last month has been small font sizes.
This was something of a mystery as it appears to be correct in the Android emulator and on the real phone which the app is developed against (a Samsung i7500).
However, after adjourning to the pub and viewing the application on several colleagues phones, the font size on some devices is indeed far too small. On inspection the small fields did not have an explicit font size set:
Update 1.22 sets explicit font sizes for all fields. This should result in more consistency across different devices.
Update 1.23 is an interim fix which applies a new font size preference to the article screen. This preference will be progressively rolled out to the remaining screens in coming updates.
