Before we try to fix screen flickering on BLU J4, let’s first understand-
What is Screen Flickering?
Screen flickering or screen flashing on a smartphone refers to the rapid and repeated flashing or blinking of the display.
It is a phenomenon where the screen’s brightness fluctuates or flashes intermittently, causing an unstable and distracting visual experience for the user.
This issue can occur on various smartphone models and operating systems. Screen flickering on a smartphone can be caused by a range of factors, including software glitches, hardware problems, incompatible apps, or incorrect display settings.
It is important to address this problem promptly to ensure optimal functionality and user experience on your smartphone.

However, it’s crucial to remember that screen flickering alone is not a definitive indication of a virus infection. Other symptoms, such as slow performance, unexpected pop-ups, or unauthorized access, are typically more indicative of a virus.
To address the possibility of a virus causing screen flickering, it is advisable to perform a thorough malware scan using reputable antivirus software. This will help identify and eliminate any potential threats.
How to Fix Screen Flickering on BLU J4
Now, you know the possible causes of screen flickering let’s see how one can solve this problem and get rid of it permanently.
There are many ways to fix screen flickering and get your BLU J4 back in working condition. Here are some tested methods that you can take to resolve the issue.
1. Disable Adaptive Brightness
The first thing you can do to fix screen flickering is to disable Adaptive Brightness.
Adaptive Brightness is a feature that adjusts the brightness of your screen based on the lighting conditions around you. While this is a helpful feature, it can sometimes cause screen flickering, particularly if the sensor is malfunctioning.
To disable Adaptive Brightness, go to Settings > Display > Adaptive Brightness and toggle the switch off.
2. Adjust the Screen Refresh Rate
Screen flickering is a common problem that can occur on mobile phones and it can be caused by various reasons, including incorrect display refresh rates settings.
The screen refresh rate is the number of times per second that the display refreshes itself. A higher refresh rate means that the screen updates more frequently, resulting in smoother animations, faster performance and response times, and less flicker.
BLU phones come with a range of refresh rate options, typically ranging from 60 Hz to 120 Hz. If the display refresh rates is set incorrectly, it can cause screen flickering, which can be quite distracting and may even cause eye strain.
