I had been using a Meizu MX6 for almost two years, and for most of that time it felt perfectly fine. At some point, though, the camera started getting worse and worse. Photos came out unclear, with a soft blur over the whole image, and the edges often looked pale and foggy.

At first I assumed it was simply because the phone was getting old. But thinking back, the camera had been much better when I first bought it, so it did not feel like normal aging alone could explain it.

After looking through discussions on the Flyme forum, I found that quite a few MX6 users had run into the same issue. After reading through dozens of posts, the suggested fixes generally came down to two possibilities:

• The Flyme system updates had negatively affected the camera, so the phone should be downgraded back to the factory firmware.
• The glass in front of the rear camera had become scratched or worn, so the camera glass needed to be replaced.

Both explanations had plenty of people supporting them. In my case, I had always installed system updates as soon as they were pushed, so the software explanation seemed possible. I decided to try the easier route first: downgrade the system, and only consider replacing the camera glass if that did not work.

With a try-it-and-see attitude, I downloaded the original factory system package from the official website. After backing up my data, I downgraded the phone.

Once the system was rolled back, I opened the camera and tested it over the next two days. I took dozens of photos, and the hazy, blurry problem did not appear again. The images looked good, which made it pretty clear that the system update had been the cause in my case.

I used to think keeping the system up to date was always the best choice, since new versions usually bring new features and a more polished interface. But more features can also mean more resource usage, and not every update necessarily works better on older hardware. The factory system is the version the phone ships with, and because it has to support the product at launch, it is usually tested very carefully. For this MX6, returning to that original system turned out to be the most stable solution.
