When Android is introduced newly, there is a company which is getting high responce was Samsung. but now and this mobile is very defective piece in Samsung history.
It hangs very much even I run only Whatsapp, mouthshut and m-indicator in my phone. There are many resons for it main reason is only Samsung’s preinstalled app.
which is very Disliked apps. no need of that apps on phone.
also I saw S3, s4 also hangs. That’s why today samsung is Saam-Sum.
