Today I am gonna say somthing about HTC desire 616 dual sim. This device is older version of androide OS Jelly Bean.
It has good preccessor Octa core. But its RAM is so small. which is only 1GB. This is very bad for phone performane.
It is small size display 5". 8mega pixel rear and only 2 megapixel of front camera. the battery is 2000mAh. If want use it for small use then this device is ok. But not usefull mutitasking and gamming. Bcos the small RAM has hang issues.
