An old flagship with many flaws.
My experience has been mixed with this device. Unfortunately, bad experiences outnumber the good ones.
I love to play heavy games and this phone heats up quite a lot, under stress. The front camera just gives up under low light scenarios. The battery can't get me through a rough day.
Rear camera is amazing though, one of the best legacy cam out there. The display is also much better than present day mid rangers. The software however, is quite ugly.
it's the old TouchWiz, not the refined one. So you'll have a ton of useless Samsung crap bloating your system.
There's update upto marshmallow 6.0, which is quite good of the company, considering this is a 3 year old device running KitKat 4.4 out of the box! But of course, updates slow down all phones, and this one isn't special.
I've been using it around 1½ years now and it has slowed down a lot. It shows lags and stutters more often now, even with anything related to the internet, like social media and YouTube.
Needless to say, there are better options out there and sadly, I can't recommend this old and now much cheaper 'flagship' to anyone.
