Fix 5: Update Your Phone
Although uncommon, certain build versions of an operating system might cause hardware-level bugs such as this. If the issue is widespread and popular, your phone must already have a software update. We recommend you always stay up-to-date with the latest Android version to squish bugs and have the best features and the strongest privacy.
To update your Samsung A03 and A03 Core, navigate to Settings > Software Update and tap on the Download & Install button next to an update, if available.
Fix 6: Factory Reset Your Phone
As the last straw, you can attempt to factory reset your Galaxy device and hope it fixes the issue. Do note that you will lose everything stored on your phone, including media such as photos and videos. We, therefore, recommend you take a complete backup of all your apps and data before factory resetting your phone.
To factory reset your Galaxy device, navigate to Settings > General Management > Reset > Factory Data Reset and tap on the Reset button. The process might take a few minutes, and your phone should boot up into a fresh operating system install.
Fix 7: Send It In For Repair
If all else fails, there is a good possibility that your phone’s display is damaged at a hardware level. This can unfortunately only be fixed properly by a technician. If your phone is still under warranty, you can try visiting an official Samsung Store to see if you can get a slight discount on the replacement.
