Today I've only been getting an Edge signal on my S4 whereas previously I was getting 3G. Strangely enough my S2 has a good 3G signal on the same network. Is there a reason for this? At first I thought it was because of the new case I was using may have been blocking the signal but it's the same even without the case. The case does contain a magnetic strip for closing it, could this have damaged anything? Or is it just T-Mobile/EE playing silly buggers?
