I bought the samsung galaxy s5 back in 2014 when it was newly launched. A fingerprint scanner and a heart rate sensors in 2k14 was very futuristic but now it is extremely common even a smartphone under 8000 has it. when it was just launched I bought it for 40000-rs.
I still sometimes use it.I came with android kitkat version 4.4.4 but now its running on the latest android marshmallow(techinally not the latest because android 7.0.0 nougat has released in a few smartphones). The phones runs quite smooth even though it has just 2gb of ram and 16gb of internal memory which can be expanable with a microsd card.The highlight is the back and front camera which perform extremely well. I hope this review helped you in any way.
