The Samsung galaxy S5 is a decent device, I’ve used this device alot so here are my pros & cons.
Pros- 5.1 inch FullHD super amoled display 432 ppi, 16MP camera with lots of great features, Good video quality, NFC, IR blaster, expandable storage, fast charging, heart rate sensor.
Cons- exynos processor which heats the phone a lot & reduces battery backup within 7 months, back is made up of cheap plastic, single sim, fingerprint scanner sometimes fails.This was a flop device of samsung S series.
