Nokia Lumia 900 Sucks!

Here a Nokia Lumia 900 from CLARO PERU SAC with defects The carrier said that this device had any defects and it was returned however as you can see touchscreen doesn't answer to finger pressing you can only use buttons but touchscreen doesn't work. It's useless Let's make a call from another phone To see if we can answer it Maybe the phone is activated after receiving a call and let's expect what happen At this moment there is another phone calling to this phone and this cellular looks as it were disconnected. There is no reaction at the phone you can see and hear the other phone making a call (to this phone) to the Nokia Lumia 900 Nokia Lumia performs no reaction at all > And the phone doesn't show any information about missed calls. It's like a frozen (hung) phone According to my carrier there was no defect No failure at all And they asked me to record it the next time it happens and that is what we are doing since them do not trust in my words. One more reason to NOT TO BUY a Nokia Lumia 900
