Solid test colors make some screen defects easier to spot than a busy photo. Device Status⁺ includes Hardware → Color & Brightness for a visual inspection of the display.
Inspect the panel
- Clean the screen and open Hardware → Color & Brightness.
- Show the available solid colors one at a time.
- Look across the whole screen for a dot that stays dark or stays bright on different colors.
- Compare a bright field with darker fields for patches, bands or persistent image outlines.
- Try more than one comfortable brightness setting.
- Return to ordinary content and check whether the same issue remains visible.
Keep ambient lighting consistent. Reflections, dust and a marked screen protector can resemble panel defects.
Separate settings from a defect
Night Shift, True Tone, Reduce White Point and automatic brightness can change the appearance. Note their state before comparing two phones; different settings can make healthy displays look different.
A single solid color does not measure color accuracy, maximum nits or refresh rate. Visual inspection is also affected by viewing angle and your surroundings. Persistent defects across colors and normal content are more useful evidence than a photograph of one unusual frame.
Does it test touch input?
No. A display can look normal while touch response fails. Use the multitouch test to check coverage and simultaneous touches separately.
