Oneplus 1 was a flagship killer developed by company Oneplus itself. It has been a while since it’s lauch and many other competitor phones have arrived but still till date I find this phone totally reasonable choice at such a reasonable price. Sleek design with sandstone back , 64 Gig of massive storage capacity , 5.5’ full HD display, 3 gig RAM . it’s hard for other phone to compete this beast.
