Samsung and their entry level devices:
I am not an anti-Samsung, my first android phone was also a Samsung. Samsung is currently the leading brand in the android market, but there are some considerations that you should consider before buying a Samsung device. Samsung’s market share is rapidly decreasing in the entry level segment as the users are getting better specifications in lower price point. For a light or regular user, Samsung devices work well but when it comes to gaming on entry level Samsung devices it simply sucks. Due to the heavy bloat ware and custom UI, a huge amount of RAM is being consumed hence heavy gaming becomes a catastrophe on an entry level Samsung device.
Their flagships are too good:
But on the other hand, the high-end Samsung devices like the S series and the Note series are the top end performing devices in the world as they have the top end specs and high optimizations with apps and games. The developers and Samsung really try to test each and every apps and game on the top end devices. So the optimization is far better. All these things create a misconception that android devices are laggy and insecure. Although the feature rich apps require high-end hardware thus they perform well on flagship devices but not in entry level devices.
