Missing letter S

[carom]

Hi

I use the phonepad keyboard, I just prefer it. When I am typing normally all the letters for that button appear across the top so you can select the letter you want to use. However the letter s has been replaces with 's, when I hit the button for pqrs7 the options are P 7 R 's Q so no letter S just 's

I had a similar issue when I got my last phone, an Xperia SP, and found a fix on this forum but have been searching and can't seem to find it.

Any suggestions appreciated. 

Thanks

Just an update, this happened again. This time the letter 'l' disappeared! Cleared the data and restarted phone then updated all my settings again and seems to be back to normal. Still no idea why letters would randomly disappear!

Getting VERY frustrated with this as now the 'S' is missing AGAIN!

Can anyone shed any light on this? Is there some sort of glitch/bug??
