Overall a good phone I am so impressed with this phonesamusng j7 is a very good mobile but we can get 3gb ram phones with in this budject but j7 is very special. it has ultra data saving mode and ultra power saving mode these things are so helpfull for me. and camera was good performence. and it had also some problems we cant lestin ringtone in noice places. and it does not contains back light. very good mobile from samsungI purchased the Samsung Galaxy J700/D a few weeks ago, I have had nothing but trouble with it. I only used the phone a few days, it started to act up, first, it froze lots, then, when I tapped the screen, it did not seem to respond until I did it a few times, then, it went super fast and turned itself off. Next, it would not receive Wi-Fi signals consistently, it is very sporadic. It is better with "Data" but even then, not too good. Today, I noticed I can not make calls from it as the reception is awful, it sounds like I am talking to robots, I cannot hear a word the other party is saying. My signal strength, no matter where I am is zero bars, so, I can not get reception at times at even the most powerful Wi-Fi hot spots. I have tried everything, uninstalled programs, re-installed, turned the unit off and on, you name it, I have done it; it just keeps getting worse and worse, however, once in a great while, it will work fine for an hour or so, then bang, it starts to shut down or act up again. I ordered it from Supero, it came from Hong Kong, I am wondering if it is a dud, the entire box, booklet, and keyboard was in oriental writing. I had to change it all over to English. I have written the company I purchased it from, but so far, they have not been very helpful. My Samsung Galaxy j5 works so much better, the only reason I wanted the J7 was due to more gigabyte room. I am sorry I did now. I certainly do NOT recommend this phone.
