In the mean time there are number of things you can do to make the text larger on Android phones. None of these options are perfect, so if you are looking to buy a new mobile and have poor eyesight I wouldn’t recommend one of the Android range. However if you already have one, these might help a bit. I haven’t managed to get hold of a handset to check these fixes, they are from online research alone.
Large text for SMS on Android
The ‘ChompSMS’ app lets you increase the font size of SMS. It also lets you change the background colours, I find inverting colours so to display white text on a black background always makes things clearer. An alternative app is ‘Handcent SMS’
Large text for general menus
The ‘Spare Parts’ app can apparently change general text size on an Android, however it is apparently rather inconsistent and doesn’t save changes well. Give it a go and let me know how it works for you!
Increase font size for browsing the Internet
The Opera mobile browser has an extra large text size which could be good.
Please let me know how you found all the above, and any other fixes you have come across.
