Bad Product

I have a Sony experia Z1. Since march 2014 that I had this phone it was giving me endless problems whit the screen and the software issues. Yesterday I used the phone in the morning, about a half an hour later, when I wanted to use the phone again after being in my car the screen went all haywire again. I cannot use any of the top functions on my screen and need to rotate it like a mad person just to send an sms. Sony does not make their phones like they use to and actually cost me to go and buy a new phone as this one is still on contract and only due for upgrade next year. I will not be taking a sony again or recommend one to any person that ask me about it. It is the worst phone ever. Its just a pity that I own so much other Sony electronic. Because of one product, I will not be replacing them with a new model but rather a different brand.
