It made me wonder about anyone who might have transferred some bitcoins to his phone only to have it die and need to be reformatted/returned, yadda. The point here isn't to slam Nexus -- there are other phones and any of them could die.
I suppose I'm wondering about other people's experiences with buying stuff offline with bitcoins face to face. I assume even on iPhone I could get to an online wallet via Safari but I'm wondering how cumbersome it'll be to have to deal with passwords in that scenario.
No idea what issue you are talking about with Nexus 4??? I have a nexus 4 rooted (running xylon and franco kernel) and it is a stellar phone. I can match it pretty much against any phone (even s4). I also have bitcoin apps & widgets installed. Haven't installed a wallet on it, but would have no hesitation. Not sure where you are getting your info. XDA forums have excellent resources to help you with your potential Nexus or any other phone.
Edit...was able to get the broken link you posted working. Most of the people on the google forum didn't know what they were talking about. Holding down power key for 10sec will give you a full reset. Some also were upgrading to new 4.2.2 OS. Regardless, I am sure if you got a defective unit google would replace it. Also make sure you always do a backup regardless of what device you have. I use titanium backup pro.
