Hi I like to share my personal experience about Samsung Galaxy S4 Mini. I brought this mobile two year back in 2014. it has good speed of RAM and the camera quality is also good it support up to 64 GB external memory card.
I use to handle it roughly and very light weight compare to other mobiles almost 80% android apps were supported in this mobile. the looks and performance is also good but now these mobile is not in market.
Battery durability is average. Its worth to your money.
If it was lollipop version then I may give 5 STAR rating.
Thank you.
