Am sure you must have heard SAMSUNG phones hang a lot. Because its famous for this purpose. Definitely, SAMSUNG is one of the best brands. Yes, it has improved a lot. And one thing is very genuine. The more you increase your budget, the better you get performance.
No doubt, its long lasting. The only phone which even if you drop it down by mistake or if it falls multiple times, it still gives service.
The problem which I faced is that it used to hang innumerably. The first few months, it worked nicely, but after a few months, you won't believe, the screen of my handset used to blink. Haha! Sounds funny, right? Yes, I showed to many servicing places, they said that its the problem of Software. So due to the Software issue, there was some kind of display problem and it appeared as if the screen is blinking.
Another major problem was the internal storage. It had 1 GB RAM which is really less. Even after days of downloading or updating the WhatsApp Messenger, it used to warn, Internal Storage is full. So I suffered a lot. And finally I had to buy another phone with a good storage. The sound quality also decreased day by day. So, I would suggest please don't buy it if you want to keep more number of things.
