Original OPPO Recommendations
The first thing you should do is put on a silicone protector that adheres to the module, protecting it from scratches or marks. The thickness of the hydrogel protector generally ranges from 0.3 to 0.5 mm and serves as a protective barrier against any falls from a height of 1 m. Qualities vary, as does their price, but they are still very economical. And you can easily apply them yourself every time it gets scratched or damaged. Thus, only the glass will break, and your OPPO screen will remain unscathed.
Additionally, we recommend applying a silicone protector which reduces the impact of falls preventing the screen from shattering. It protects the edges. One of the most commonly used ones has a border that protrudes above the display so that when it falls on the ground, it does not touch it.
Another popular recommendation is the wallet-simulating case. Not only can we carry our phone with style, but it also prevents theft.
How to know if your screen is damaged
Before concluding that it stopped working entirely, we must determine if it’s the screen protector or the module that is broken.
If the touch function fails, we will notice the exterior chipped but the display continues to work normally. However, the LCD will be damaged if the OPPO A78 5G stops working, meaning if only half is visible, horizontal lines appear, or it is all dark. To further verify if you need to replace it, go to settings. Then, to “Phone Information” and tap 7 times on “build number”. This will give you access to “developer options”.
Inside this section, select “pointer location” and trace the entire area of the screen. If these do not appear, it is assumed that there is an issue, and you will need to repair it.
