    It's a good phone, but flickering on the screen is unacceptable. It causes a lot of headache and you cannot stare at it for longer than 30 minutes.

    This phone gets really hot and i dont even play games on it. After downloading a few apps, there is only 2gb of ram left out of 8 and only like 35gb are being used out of 265. Plus only one case fits properly on this phone
