What you said is all about the advantage of this phone , can you show me sth on its shortage

This phone is going to be a top seller without a doubt. It's memory alone makes it easier to use than previous android phones. It has 32GB on-board memory but does not have an microSD card slot. It has a Honeycomb multitasking feel to it and Samsung has made some incredible improvements in its auto correction. The Face to unlock is a great security feature and is extremely easy to use. It has a proximity sensor so that no one can just hold up a picture of your face to unlock it. If, for some reason, the face to unlock does not work, you can always put in a pattern to unlock. Overall this is winner and I recommend it to anyone wanting a great looking phone.
