You can change the fonts on your UIQ devices. You need to copy the fonts files into your memory card. You must place the files in X:/resource/fonts/ where X: represent your memory card.
There will be four fonts files inside the folder. If you do not have the above folder, you can create yourself using Windows Explorer. Everytime, you can only load 1 type of fonts in your UIQ. Delete the four files in the font folder before u download new fonts files to the folder. Restart your UIQ device after u copy the new fonts files.
