The problem
Here we discus a common camera problem of some Xiaomi Redmi 2 (and Redmi 2 TD, and Redmi 2A). The problem is that the camera cannot focus on distant objects (and apparently cannot focus on infinity) but can focus on close objects (macro).
Symptoms
This can be noticed also as a lack of sharpness on distant object contrary to close objects which appear sharp. Other symptoms are the difficulty to focus when trying to focus on distant objects. Focus in that case is "hunting" and even when appears to "lock" in fact it is out of focus.
How to repair
Generally you need to sent it back for repair. But when you buy from china postage might be more expensive than repairing it yourself.
