The reviews from several others mentioning Touch-Screen not being very great/responsive(AND) the battery life being very poor are all 100% accurate. I bought a phone 2 days ago and have experienced the following problems in the last 2 days:
1) Wifi goes off on its own and when you search the network it does not pull up any UNTIL you restart the phone
2) Battery charged at night to 79%(with the phone unused all night through) shows up as only 23% in the morning - With NO USAGE
3) Touch Screen is slow to respond and you have to touch the option several times(sometimes) especially after just unlocking the phone to use it.
I plan to take the phone to the service center in a few days. Will let you know how responsive they are when I do that.
I did not buy the phone online, I bought it from an authorized dealer(a huge branded store) but I guess the phone is not worth its money with all these issue. I bought last Sunday 5th June 2016 is really good except the battery performance. battery drains very fast. I charge the battery at night and when I wake up and check the battery level, it comes down to 55 - 60 percent. I am shocked and dissapointed.
