I have been swapping back and forth since the GN was released.I haven't had any issues or had to do any soft restarts,just pull from one and put in the other but I make sure the phone is off when I insert the sim card.My GN must be one of the ones with a bug because it is just slow in every aspect and the speaker sucks along with it dropping coverage alot.I cannot return it as I dropped it on my way into the store and it cracked the top left corner of the screen(not bad but noticeable) so I have to go through asurion.I do wish I could swap it to try another one as I did have to go through two prior razrs before I got a perfect third one.so there are deffinetely some phones out there that give a phone a bad wrap if someone got a bad one first.
I here alot of people getting on someone who wants a better camera on the gn. I for one agree the camera sucks,atleast on mine(as stated above all phones seem to be different).But the camera on my razr takes beautiful photos.I don't expect a digital camera but when there are better cameras on previous phones(charge) why would you put a less capable camera on your premier phone.
These of course are my 2 cents having both the razr and gnex to mess with.I hope this may be of some help to someone.
