I presently used this phone. This phone has 3gb ram 32gb rom and octa-core processor and speaker is also good. Mic and speaker on the front of the display and its design are also nice, screen quality is super fine.
Talking about its camera quality, HTC provides 13 megapixels back and 5mp pixel front and the battery is about 3000mh and its weight is 196gm, screen size 6inch.
