I used samsung galaxy s7.its a phone made out of metal and glass with corning glass 4 on screen and screen size is 5.2 inches.its has touchwiz OS and built on android 6.0.1.
I dont like the fingerprint semsor on that .it was too buggy in nature and does not read fingerprint properly.the touchwiz OS is very laggy and sometimes phone heats as hell when charging.no doubt it has best camera but sometimes pictures comes out to be really overexposed.overall its nt worth the price.
