Samsung screen problems fall into a short list, and each one has its own page: a black or white spot (pixels, pressure, backlight), a line (panel connector, cable, or graphics), a colour cast (settings or panel ageing), flicker (settings, cable, or connector), burn-in ghosts (OLED ageing), a blurry image (settings), half the screen blank (panel driver), or touch that stops responding in one area (digitiser).

Test it now

Full-screen white, black and grey, then the three colours. Note what you see, on which colours, and whether it changes with pressure. Then answer the questions on the home page, or pick the matching symptom from the list below.

What it is

Samsung screen problems fall into a short list, and each one has its own page: a black or white spot (pixels, pressure, backlight), a line (panel connector, cable, or graphics), a colour cast (settings or panel ageing), flicker (settings, cable, or connector), burn-in ghosts (OLED ageing), a blurry image (settings), half the screen blank (panel driver), or touch that stops responding in one area (digitiser). Run the full-screen colours and use the three questions below to land on the right one. Samsung AMOLED phones burn in at the navigation bar, status bar and keyboard first. Samsung service replaces the display assembly; there is no repair short of that.

Can it be fixed?

Settings and software faults: yes. Cables and connectors: usually, as a small repair. Panel faults: replacement. The pages linked below say which is which for each symptom.

What to do

Full-screen colours.
Screenshot: fault in the screenshot = software or graphics, not the screen.
Match the symptom to a page below.
In warranty and no impact or pressure: claim before paying.

What a repair costs

United States	$80–200 for a display on most Android phones; $200–380 at Apple for an iPhone screen out of warranty ($29–99 with AppleCare+)
India	₹2,000–6,000 for a display on budget and mid-range Android phones at an independent shop, ₹6,000–20,000 for flagship OLED screens at the brand service centre; iPhone screens ₹12,000–35,000 at Apple-authorised service

Typical ranges from repair-shop and manufacturer price lists, 2026-09-06. Get two quotes; prices vary by model and city.

Warranty

Most makers replace a panel under warranty for physical panel faults that are not accidental damage; pressure marks, cracks and liquid damage are treated as accidental and are not covered. For dead pixels, each brand has a threshold (typically 3–5 bright or 5–8 dark pixels on a laptop; Dell's premium-panel guarantee replaces at one bright pixel).

Every phone symptom

Why is there a purple line on my iPhonePurple vertical lines on an iPhone screen are almost always the display itself: the flex connector between the panel and the board has lifted (often after a drop or a swollen battery pushing from behind), or a row or column driver on the panel has failed.Depends — see test Bright spot on iPhone screenA white spot on an iPhone screen that glows on black is one of two things.Depends — see test Galaxy S8 screen linesA line on a Galaxy S8 screen is almost always the display itself: the flex connector between the panel and the board has lifted (often after a drop or a swollen battery pushing from behind), or a row or column driver on the panel has failed.Depends — see test Note 9 screen color issueA phone screen that has turned off-colour — the whole screen, not a patch — is one of four things, in order of likelihood: a colour setting (Eye comfort / Night Light / a colour filter under Accessibility / a wallpaper-based theme), an OLED panel ageing or damaged so its colour balance has drifted (a cast that is worse at low brightness), a lifted display connector after a drop, or liquid in the display.Fixable Yellow spot on my phone screenA yellow spot on a phone screen is heat or adhesive: on an OLED the organic layer has aged where the phone runs hottest (the bottom, near the charging port and the processor), and on an LCD the optical adhesive between glass and panel has yellowed or separated.Depends — see test Phone screen turning greenA phone screen that has turned green — the whole screen, not a patch — is one of four things, in order of likelihood: a colour setting (Eye comfort / Night Light / a colour filter under Accessibility / a wallpaper-based theme), an OLED panel ageing or damaged so its colour balance has drifted (a green cast at low brightness is the classic AMOLED sign), a lifted display connector after a drop, or liquid in the display.Fixable Phone display problemPhone screen problems fall into a short list, and each one has its own page: a black or white spot (pixels, pressure, backlight), a line (panel connector, cable, or graphics), a colour cast (settings or panel ageing), flicker (settings, cable, or connector), burn-in ghosts (OLED ageing), a blurry image (settings), half the screen blank (panel driver), or touch that stops responding in one area (digitiser).Depends — see test Grainy screen protectorA grainy, sparkly or slightly rainbow look after fitting a screen protector is the protector, not the screen: matte protectors scatter light and make white look like fine sand, and a cheap glass protector with a thick adhesive layer adds a faint moiré against the pixel grid.Fixable S8 black dot on screenA black dot on a phone screen that shows on white and vanishes on black is inside the panel: a cluster of dead pixels (a sharp-edged tiny square), a pressure mark (soft-edged, where something pressed the panel), or dirt under the glass (moves if you press gently, on tablets and monitors only).Depends — see test Why is my phone screen green?A green tint over the whole phone screen — or a screen that goes fully green — has two very different causes.Depends — see test Blue spot on phone screenA blue spot on a phone screen is OLED damage: the blue sub-pixels in that area have been knocked out of balance by pressure or a knock, so the area renders blue where it should be white.Depends — see test Grey spot on phone screenA grey spot on a phone screen is a dimmed patch: pixels that still work but weakly.Depends — see test
