If your vivo S50 screen starts flickering, flashing, or dimming randomly, it can make the phone difficult to use. The display may blink when adjusting brightness, opening apps, or even while idle. In most cases, this issue is related to brightness settings, software glitches, or display calibration problems, not hardware damage.
Before visiting a service center, try these proven fixes.
Why Your vivo S50 Screen Is Flickering
- Adaptive or auto brightness is misadjusting the display.
- A recent software update introduced display bugs.
- Third party apps are interfering with screen rendering.
- High refresh rate conflicts with certain apps.
- Physical damage or loose internal display connectors.
1. Restart Your Phone
A simple restart refreshes the display driver and clears temporary software issues. Many flickering problems disappear after a clean reboot.
Press and hold the Power button, and then tap Restart.
Wait for the phone to fully boot up, and then observe the screen.
If flickering stops, it was likely a temporary glitch.
2. Turn Off Adaptive Brightness
Auto brightness sometimes keeps adjusting the screen rapidly, which may look like flickering. Disabling it allows you to test whether brightness control is the cause.
Open Settings, and then tap Display and brightness.
Turn off Auto brightness, and then manually adjust the brightness slider.
Use the phone for a few minutes and see if the issue continues.
3. Lower or Change the Refresh Rate
Higher refresh rates can cause instability in certain apps. Switching to a standard refresh rate can stabilize the display.
Open Settings, and then tap Display and brightness.
Tap Screen refresh rate, and then select Standard instead of High.
Check if the flickering improves afterward.
4. Check for Software Updates
Display flickering sometimes appears after minor system bugs. Installing updates can patch these issues quickly.
Open Settings, and then tap System update.
Tap Check for updates, and then install any available update.
Restart the phone after installation to apply changes.
5. Boot Into Safe Mode
Some apps with screen overlays or brightness controls can cause flickering. Safe Mode disables third party apps so you can test the phone safely.
Press and hold the Power button, and then tap and hold Power off.
Tap Safe mode, and then wait for the device to restart.
If flickering stops in Safe Mode, uninstall recently installed apps.
6. Reset Display Settings
Incorrect display configurations may trigger instability. Resetting them restores the screen to default calibration.
Open Settings, and then tap System management.
Tap Reset, and then select Reset all settings.
This will not erase personal data, but it will reset system preferences.
If none of these steps fix the flickering, the issue may be hardware related. In that case, a display inspection at an authorized service center is recommended.
Screen flickering on the vivo S50 is usually software related and fixable within minutes. Start with brightness and refresh rate adjustments, then move to Safe Mode and resets if necessary.
FAQs
Why does my vivo S50 flicker at low brightness?
OLED panels sometimes flicker at very low brightness levels due to PWM dimming. Increasing brightness slightly can reduce the effect.
Can screen flickering be caused by apps?
Yes. Apps with screen overlays, blue light filters, or custom brightness controls can interfere with display rendering.
Is screen flickering a sign of hardware damage?
Not always. Most cases are software related, but if flickering persists after resets, the display panel may need professional inspection.
