If youre buying for clicking nice photos and videos, then swiftly avoid it, the camera is not for you. Other than that, it’s a fine phone, fast processing, superfast fingerprint censor and cool weight distribution and not like typical light weight phone of realme brand. Only weird thing is that I couldn’t find a FILE MANAGER and GALLERY application in it. Very very weired.
