crwdns2890332:0bottom touch is nt workingcrwdne2890332:0It's going to be the digitizer. They are the most common cause of faulty touchscreens. Although there is a very slim chance that it is something to do with the motherboard. If this is the case it would most likely need to be sent off to some professionals. However that would cost lots. It would be better to attempt to fix it, but there is a chance of breaking it - if you have some common sense it will be ok. :) If you are in need of more help, contact me Regards, Elliot Edwards.
