From what i've read, I'm starting to think it's the 64gig units that are a problem. Hubby has 32 gig wifi... He's had zero problems. Sitting next to him with the 3G 64 gig I have a weaker signal, and the signal isn't steady.
Nothing scientific, but I was surprised to run into an issue since it's all been flawless with my husbands for the last two weeks.
I will test it but not sure how. Is there an app that will show you the reception? I already did a wifi speed test and they were pretty much identical.
