Reasons why S21 Ultra screen has stripes
The S21 Ultra screen has stripes that usually appear as straight lines or irregular colored streaks that stretch across the screen, causing the displayed content to be distorted. This problem can occur for many reasons, from hardware failures to software errors and needs to be handled promptly to avoid the situation from getting worse.
Hardware error
● Screen damage due to impact or fall: Strong impacts or falls from heights can deform or crack the screen, leading to stripes. This impact creates pressure on the screen, affecting the pixels, creating stripes.
● Loose or damaged cable between the monitor and the motherboard: This cable plays a role in transmitting signals from the motherboard to the monitor. When the cable is loose or damaged, the transmission signal is interrupted, causing stripes on the screen. Loose or damaged cables can be caused by careless use of the device, causing the cable to be stretched or compressed.
● Faulty display controller IC: The display controller IC is responsible for processing signals and displaying images on the screen. When the IC is faulty, the signal is distorted, resulting in abnormal stripes appearing on the screen. This error is often caused by the manufacturing process or using the device in harsh environments, causing the IC to be damaged.
Software error
● Android operating system error: The Android operating system may have errors, leading to incorrect display, creating stripes on the screen. The operating system error may be due to an error that occurs during the update process, or due to a virus attack.
● Application errors: Faulty applications or conflicts with the operating system can cause display problems, including screen stripes. Faulty applications are often caused by errors that arise during installation or updating.
● Faulty display settings: Inappropriate screen resolution settings, faulty display mode, or conflicting display settings can also lead to screen stripes. This error is often caused by the user accidentally changing the display settings, or by system settings errors.
