I bought this this phone 3 yrs ago and stopped using it within 1 yr. I will tell my personal experience with this phone.
For first few months it was working okay eventhough I had difficulty in handling such a big sized phone.
It is hard to use it with one hand.
This phn got hanging issues and I had to switch it off every now and then. It would take long tym even to make calls since the loading tym was too much.even opening the screen lock took a lot of tym.
I repaired it via samsung help centers few tymes but the issue came back again.
The camera was not of good quality. It was a struggle to take photos in dim lighting.
It got stuck all the tym and started to play music and open apps on its own. I had no other option than to throw away this phone.
The only positive I found is that it has a long battery life and the S pen was not that bad.
I would not suggest you to buy this.
Worst experience.
