About this app

Does your phone really support HDR? HDR Check gives you a clear, instant answer — reading your display's true HDR capabilities straight from the Android system. No guesswork, no test patterns to stare at, no account, and no internet connection.

Open the app and see at a glance whether your screen is HDR-capable, which HDR formats it supports, and how bright it can actually get.

WHAT HDR CHECK TELLS YOU
• HDR verdict — a simple "HDR supported" or "No HDR" answer for your display
• Live HDR indicator — see whether your screen is in HDR mode right now
• Supported formats — Dolby Vision, HDR10, HDR10+ and HLG, shown as clear badges
• Declared luminance — peak, average and minimum brightness in nits
• Wide colour gamut — find out if your display covers a wider range of colours
• HDR capability — confirm hardware-level HDR support

WHY HDR CHECK
• Reads directly from the system — accurate, device-reported data, not a visual guess
• 100% offline — no network access, nothing leaves your phone
• Privacy-first — no sign-in and no tracking of your personal data
• Fast and lightweight — get your answer in a second
• Clean Material You design with light and dark themes

PERFECT FOR
• Checking a new phone or tablet before you buy, or after a software update
• Confirming HDR before streaming Netflix, YouTube, Disney+ or playing HDR games
• Comparing the displays of two devices side by side
• Anyone curious about what their screen can really do

HDR (High Dynamic Range) delivers brighter highlights, deeper contrast and richer colours — but not every display that plays an HDR video actually supports HDR well. HDR Check shows you exactly where your device stands, using the same capability data Android reports to apps.

Download HDR Check and find out what your display is really capable of.
