If still not workingl, we will have to Factory Reset the phone and test again to see if this is a hardware issue or software. Factory Reset will resolve most software issues.
Hi Nick sorry to only just get back to u got very poorly ( i do a lot ) very quickly so many apologies. I have now done all u suggested with no hapy resolution unfortunately. I am very concerned and worried if we di a factory reset that i will lose everything off phone e.g pictures videos of now passed on animals and friends, all things i have set on my phone all downloads, personalised rung tones etc. These are things( esp photos and videos) i cannot afford to lose as have no others the same. I wld be mortified and so so gutted if i lost them. I f there is a way to keepall as is to do this factory reset then i wld welcome any other help u can advise. I dont expect a reply tonight and offer my apologies now if i dont get back to u straight away.
Connect your phone to computer and select Restore. Select the Backup file that you did earlier to restore your phone back to where it was.
