Hi, So I received my Sprint GS6 Edge 64gb on 4/8/15 and immediately I noticed all other hairline scratches some one have been getting. Does anyone know how long it would take to replace the phone or even if its worth replacing considering all the backorder and that people haven't even gotten the phone yet? Also, ever since I setup the device, I have lag here and there. The phone is ultra fast but still stutters MORE than my Nexus 5... I can get tasks done faster on my Nexus just because it doesn't have all these hickups here and there. Anyone notice this or experiencing this? Does anyone know the solution? I already got a Sprint OTA of 100 and something MBs, that didn't do anything. :(
