Home Screen has reset and cannot customise
Hey everyone. I got my HTC one a few days ago and I got a message saying something along the lines off "I new SIM card has been dectected, do you want to install SIM apps". I clicked asked later and customeised the home screen and the 'toolbar' at the bottom (i switched the stock messenger app for whatsapp).
The messege came up again today and I clicked install. I now have an app called Best Deals and my home screen was reset, the wallpaper stayed the same but the apps disappeared. Now I can't swap the messenger app for whatsapp.
Does anyone know how to fix this? I've attached a picture of the 'toolbar thing.
