Samsung S3 freezes after 4.3 update and doesn't recognise my sim
I just updated my S3 to 4.3 (my network is 3 - UK) and the phone is so slow! All programs crash after a few minutes of going onto them. I keep getting messages like "unfortunately the process com.android.phone has stopped".
Also I have no mobile network!! Everytime I click on mobile data is tells me to "insert an active sim to access network" but when I put the sim in my brothers phone the sim works.
I really don't want to do a factory reset as I have a lot of internal things saved such as pics and whatsapp conversations that I really need!
Please can anyone help me?
Is it possible to go back to 4.2?
I feel like I want to cry!
Help someone.... please!
