Part 4: Frequently Asked Questions

Aside from the methods and tools discussed for fixing dead pixels on phone screens and stuck pixels on the phone, you may still have some questions regarding the issues. Whether you are dealing with a single stuck pixel or a cluster of dead pixels, this section aims to provide you with helpful insights.

1. Can Dead Oppo A2s Fix Themselves?

No, a dead pixel on the phone is permanent. There is a much lower chance that dead pixels will self-correct over time. They are often impossible to fix using any of the widely used techniques. Unlike stuck pixels, they rarely have a chance of recovery. Before giving up, verify if the pixel is dead, as stuck pixels may be fixable.

2. Can Dead Oppo A2s Worsen?

Dead pixels cannot spread because each pixel functions independently of the others. Thus, a dead pixel on the phone does not affect surrounding pixels. However, it can be a nuisance for users, especially if it appears in prominent parts of the screen. Call an expert if you see that it is spreading so they can diagnose the issue and assess whether a repair is possible.

3. Why Are Dead Oppo A2s Spreading on My Oppo A2?

It simply signifies that this specific area of your screen had poor manufacturing quality or is physically damaged if you have a patch of closely spaced dead pixels on your phone. When a group of dead pixels is close together, it indicates localized damage or defect to that specific area. So, the pixels in that region no longer produce light or color.

4. How Many Stuck Oppo A2s Are Acceptable?

It frequently happens throughout the LCD manufacturing process when one or more subpixels enter an unchanging state, leading to a bright or lifeless pixel. Generally speaking, an acceptable display has 1 to 5 fixed subpixels.

In addition, the essential factor in comparing dead pixel policies is whether or not the policy permits the Oppo A2 devices to be returned, swapped, or repaired when this frequent issue arises.
