All sorted thanks Hi, I've been trying to get into my work books to finish up, and it says that after a year I would need to upgrade it... I haven't had it for a year and this is the app that we were asked to download for our course work? Plus I've updated this app many times over the last 3 to 4 months which make the app slower now unless it's my phone that's struggling. Could you help me with this please?

When you enter an one arabic letter, it is automatically placed on the side and cannot be edited. The alternative way is to use one latin letter, then replace it with an arabic letter. Inefficient!
