My karbonn titanium S21 is more effective in look, battery, desing, processor, ram, internal storage, browsing as compare to other mobiles at this range.
I operate it very lightly , sometimes it become slow when lots of apps intalled in the phone but obviously this phone at this range is very good. I refer this app those who have to buy very good mobile in their budget. Only the camera quality is not so good but in this phone primary and secondary both camera are there.
