My phone suddenly locked itself nearly 4 weeks ago, no reason for it, just suddenly would not accept my pass code. 4 weeks later, after constantly calling Samsung and being told they were looking in to it, being told the issue would be escalated, being told someone would come back to me (which they never did until I called them) being told they had tried to contact me to give me updates twice (which was a pack of lies because there were no missed calls on either of my phones), I have now been told to do a factory reset on my phone, which means losing all the information on it, which includes irreplacable photos (as I have tried to explain time and time again). Their response, maybe do a back up of your photos next time!!! Phone is going in the bin and I am buying an Apple - will never deal with this pack of uncaring, unprofessional, lying people ever again.
