I bought this phone in 4k from ebay, In my using experience phone is good but some very important things are not present.
1) No auto brightness senser.
2) Auto screen off while calling is not present, since while calling anyone call get disconnect or speaker on from touch and therefore it’s use more battery.
3) It is have 5 mega pixel camera but not auto focus or tap to focus.
in my using experience mobile looks good, low lag but some very important things are missing, therefore I not recommend this mobile.
