Impressive spec on paper but performance slowed down in just 2 weeks of usage Loaded 1600 contact and phone would not show the contact name most of the time and only number would get displayed I had he same problem with my Gionee Marathon 2 M2 All these phone with Mediatek processor and big battery slows down the phone I guess So check with others before buying but it provides great battery life display is not so good performance is okay
