This is one of the best functional and affordable smart phones available. The Google Play Store is awesome on this phone! Battery Life Its battery life has a decent amount of time on it as long as you're using it moderately. Display/Screen Quality The LCD screen has a very high picture quality. What it has to offer makes everything look real life like. Call Quality I have never had any problems with any calling features with this phone. All of the settings work very well. Ease of Use No headaches or regrets for this phone. Even a first time user would be able to get the hang of it even though it is a high quality in phone, because the Android icon on the home screen offers a very good tutorial wizard. Durability This phone new or used provides good function and can last a user a long life of the phone itself. Unless you are using it also for a hotspot other than making calls or/and in those jeans and other little activities and applications this phone has to offer, it very durable. Design It has become a very common piece of equipment and is very attractive to the eye of its beholder.
