Htc one A9 is good phone. The feature of this phone are its weight is 143gm, its screen is about 5.5 inch large & its is available in Android 6.0. It is fantastic phone. The camera of this phone is 13megapixcle in back & the front camera is about 4 megapixle. I also have this phone. The internal memory is about16/32 gb. The ram is 2/3 gb & it also support memory card also upto 2TB.
The only bad thing about this phone is the front camera t is 4mp & the battery is non removeable this is bad this about this phone & the total phone is good. The company should improve the bad thing.
