I'm new to Huawei phones having had an iPhone for years and feeling a bit confused! Ive just bought the p20 lite and was looking forward to using the camera as I'd heard good things. I know it's not as good as the p20 or pro so wasn't expecting that quality but the quality I'm ending up with is pretty dreadful. Even in good light pictures are always grainy and fuzzy looking. When you zoom in the detail is really poor. What am I doing wrong?
