I bought this phone in January. At first I was very happy, although 8GB internal memory in the end it is much too little! With the Android update for Lollipop I lost a lot of space and I end up with 4 GB of memory, which is not huge because I shoot a lot and I have a lot of applications . So good product, very easy to use and intuitive, no problem about that. Only problem: it a few weeks ago, the touch of my phone suddenly started bugue. I had to press 4 times a button to work and there is getting worse! Looking on forums I visited that this was a recurring problem in this model, apparently due to a defect in the model. So I had to get back to the service that will run my guarantee I will probably be repaid, but all that to say that if you do not want to be bothered, better get the Desire 820 that apparently works well. It is a bit more expensive but ... Otherwise other thing I found a little unpleasant passing HTC is no central HOME button like Samsung or Apple. I had a Samsung before and I admit that I lack a little button.
Conclusion: a good phone but I do not advise you as recurring problems touch !!
