I dislike that it has no expandable memory. My 16gb filled up fast. I dislike that it has non removable batteries....as the battery performance , especially idling, is quite poor. I dislike that it uses glass screens as I just dropped it from 30cm height and it shattered.
I also dislike how difficult it was (shortages) and how difficult it is to find one ...limited markets, limited payment options....
That said I just ordered another replacement as I really really hate the carrier/vendor-customized software. Otherwise the HTC One or the Sony Xperia Z would be much more attractive
I thought the galaxy nexus was a better phone
