I have been using this phone since last 3 years. It is very good phone but in terms of performance only as it has Octa-core processor and 2GB RAM. Also it has 16MP camera which is of very good quality.
This phone has 2 variants 3G(SM-G900H) and 4G(SM-G900F). I am using 3G variant but now a days 4G sim’s are becoming more popular. That’s why I can’t use these sim’s in my phone. This is the main drawback of this phone. But otherwise this phone is good in every aspect.
Also the 3G variant has octa-core processor and 4G variant has quad-core processor. now it depends upon you what you want? If you want a powerful processor than go for 3G variant otherwise 4G.
At starting this phone was launched with price tag of Rs.50, 000-55, 000 but now you can buy this phone from any shopping website with a price of Rs. 15, 000-20, 000.
