With the new I had less trouble, they seemed at least to be processed properly, but after a year or so also occurred because of system failure, unfortunately, I had no guarantee ..
In general I have to say in my use, that this brand is really nothing for me to now 4 Samsung phones. Everything is produced as plastic, processing up to scratch and the phones get all the latest after 2 years strong system errors and operation difficulties. And again without a debate on Apple VS. Begin Samsung, I want to mention only times that my iPhone that now is 5 years old has (since 2010) never made me such problems, super processed was (not so squeaky or wobbled) and always was perfect to use and more sensitive to touch etc reacts as it did the Samsung, although the iPhone was older.
2 stars I was only because of the AMOLED screen from Samsung was very colorful and also one of my main reasons for purchase and had the camera itself also was quite good. By today's standards the phone, however, with currently 360 totally overpriced. I paid 2 years ago grad mal 250th
