Well I recieved my parcel to try out the ultra z and when we opened it as wife was going to use it rather than me. We was a little shocked at how big it was.
Overall the ultra is a very good phone.
Screen nice and clear very gd for watching videos.
Battery is very reasonable for the size of screen would last for a day at least.
Operating system is good (first time with high end andriod) smooth and fast when opening apps.
Speaker having only one is a bit rubbish if you want to watch films on the ultra. It would benefit from having two. But if connected to a bluetooth speaker or headphones sound is very gd.
Camera is good
My wife has used it mainly with her kindle app.
I would recommend this phone to somone who is maybe on a budget and wants a tablet/phone but maybe can't afford to get both. This is not a phone that will be put in your trousers pocket, it will need to be in a school bag or handbag. If you are looking for a tablet, phone and e-reader all in one this is the phone for you.
Overall my wife likes the phone and is now looking at the z3.
