Why screenshots on Android are of poor quality - a complete analysis of the reasons and solutions

Did you take a screenshot on your smartphone, but instead of a clear image, you got a blurry mess, dark spots or pea-sized pixels? The problem of poor quality screenshots on Android occurs more often than it seems - and the reason for this is not always “crooked hands”. Even flagship devices from Samsung, Xiaomi or Google Pixel can produce screenshots with artifacts, if you do not take into account the nuances of system settings, firmware features or hardware limitations.

In this article we will analyze 12 key reasonswhy screenshots lose quality - from a banal reduction resolutions to hidden bugs in the graphics driver. You will learn how to diagnose a problem in 30 seconds, what settings Android affect the result, and why sometimes it is not the phone that is to blame, but the messenger into which you upload the picture. And also - step-by-step guide for every case, including rare bugs that are kept silent even in service centers.

Spoiler: in 80% of cases the problem is solved without root access and flashing. But there are exceptions - for example, when it is to blame a hardware defect in the display controller that “cuts off” the color profile when capturing the screen. How to distinguish a software bug from a hardware bug - read below.

1. Reduced screen resolution in system settings

The most obvious, but often ignored reason is screen resolution in the smartphone settings. Many users set the value HD+ (720p) or FHD+ (1080p) instead of the native display resolution to save battery power. However, screenshots are taken at the same resolution as the current screen output. If your Samsung Galaxy S23 Ultra physically supports 3088×1440, but works in 2316×1080mode, then the screenshot will be in 1080p —with a corresponding loss of detail.

How check:

• 📱 Open Settings → Display → Screen resolution.
• 🔍 Look at the current value. If it is below the maximum, this is the first reason for bad screenshots.
• ⚡ Please note: increasing the resolution will increase battery consumption by 10-15%.

Exception: on some devices (for example, OnePlus 11) screenshots are taken in native resolution, regardless of the current screen settings. But this is the exception rather than the rule.

2. Compressing screenshots by the system or applications

Android by default saves screenshots in format .png or .jpg with compression. In most cases this is not critical, but some manufacturers (for example Xiaomi in firmware MIUI) aggressively compress images to save memory space. The result is artifacts in the form of “squares” in monochromatic areas or blurry small details.

How it works:

• 📁 The system can automatically convert .png (lossless) in .jpg (lossy) when saving.
• 🤖 Some shells (for example, ColorOS on Oppo/Realme) reduce the JPEG bitrate to 70–80%, which is noticeable in the text and gradients.
• 📱 Applications like WhatsApp or Telegram additionally compress screenshots when sending, even if the original was in high quality.

Solution:

1. Check the saved format screenshot (file extension).
2. If this is .jpg —try taking a screenshot via ADB (command below) or a third-party application like Screenshot Easy.
3. To send to messengers, use archives (.zip) or cloud services (Google Drive, Dropbox).

3. Graphics driver or firmware errors

If screenshots are obtained with stripes, a greenish tint or “torn” edges, the problem may lie in the graphics driver (GPU driver) or a firmware bug. This is especially true for devices on chips. data-i="96">(series Mediatek (series Helio and Dimensity), where drivers are often updated with errors. Bugs also occur after major updates Android (for example, when switching to Android 14).

Signs of problems with the driver:

• 🎨 Distortion of colors (for example, a blue tint instead of black).
• 🖼️ Artifacts in the form of horizontal stripes or “snow”.
• 🔄 The problem appears only in certain applications (for example, in games or Chrome).

How to fix:

1. Update the firmware to the latest version (check in Settings → System → Software update).
2. If the problem appeared after the update, roll back to the previous version (instructions for your model are on the forums 4PDA or XDA Developers).
3. For devices with Mediatek try manually updating the GPU drivers via Mtk Droid Tools (an unlocked bootloader is required).

4. Defects in the matrix or display controller

If the screenshots are obtained dark, with spots or uneven backlight, but these defects are not visible on the screen itself, the problem may be a hardware defect in the display controller or matrix. a rare but critical case when, when capturing a screen, the system reads distorted data from the display module.

How to diagnose:

• 🔦 Take a screenshot of a plain background (for example, a white screen in Google Keep). If dark spots or gradients are visible on it, this is a hardware problem.
• 📸 Compare the screenshot with a photo of the screen taken on another phone. If there are no defects in the photo, but there are defects in the screenshot, the controller is at fault.
• 🔧 Check for physical damage (shocks, falls, moisture).

Solution:

In this case, software methods are powerless. Contact a service center to diagnose the display module. The cost of repair depends on the model:

5. Incorrect color profile settings

Many modern smartphones allow you to select Screen color profile —for example, Saturated, Natural or AMOLED Cinema on devices Samsung. These profiles change the color gamut Display only, but some manufacturers also use them when capturing the screen. As a result, the screenshot may turn out too dark, greenish or overexposed.

Where to look settings:

• 🎨 Samsung: Settings → Display → Screen Style.
• 🖌️ Xiaomi/Redmi/Poco: Settings → Display → Color Mode.
• 📺 Google Pixel: Settings → Display → Colors.

How to check the influence profile:

1. Take a screenshot in the current profile.
2. Switch to Natural (sRGB) and take a screenshot of the same screen.
3. Compare the files - if the colors are different, it's the culprit profile.

Install the profile Natural (sRGB)|Take a test screenshot of a white screen|Compare with previous screenshots|If necessary, reset the display settings to factory settings-->

6. Conflict with screenshot applications

Side screenshot applications (for example Screenshot Touch, Super Screenshot) may conflict with system services or use their own compression algorithms. Sometimes they even intercept standard combination of buttons (Power + Volume Down), but save the image in low quality.

Signs of conflict:

• 🤖 Screenshots are saved in application folder, and not in the standard one Pictures/Screenshots.
• 📉 The quality deteriorates only when using hot keys, and not through the system menu.
• 🔄 After uninstalling the application, the problem disappears.

How to fix:

1. Uninstall all third-party applications for screenshots.
2. Reset the default settings for the “Screenshot” action in Settings → Applications → Default applications.
3. If you use Nova Launcher or other launchers, check their settings for interception screenshots.

⚠️ Attention: Some applications (for example Screenshot Easy Pro) offer “improved” quality, but in reality they simply increase sharpness after the fact, adding noise. This does not correct the actual resolution, but only masks the blur.

7. Performance limitations (thermal throttling)

When the smartphone overheats, it automatically reduces performance to prevent damage to the chipset. In rare cases, this also affects the process of creating screenshots - the system can reduce resolution or apply aggressive compressionto reduce the load on GPU. This is true for devices with poor cooling (for example, Redmi Note series or Poco X).

How to check:

• 🌡️ Install the application AIDA64 and check the processor temperature while taking a screenshot.
• ❄️ If the temperature is higher 60°C —let the phone cool down and try again.
• 🔋 Close background applications (especially games or Chrome with many tabs).

Additional measures:

• 🧊 Use a cooling pad or fan (for example, Black Shark FunCooler).
• 🔄 Turn off Adaptive brightness and Adaptive screen refresh in settings.
• 📱 For Samsung disable Performance optimization in Settings → Device maintenance → Battery.

8. Bugs in specific applications (games, social networks, banking applications)

Some applications block or distort screenshots for security reasons:

• 🎮 Games (PUBG Mobile, Genshin Impact) can save screenshots in low resolution due to protection against cheats.
• 🏦 Banking applications (SberBank Online, Tinkoff) often make screenshots black or blurry.
• 📱 Messengers (Viber, Signal) can hide notifications in screenshots.

Workarounds:

1. For games: use the built-in screenshot function (for example, Game Tools on Xiaomi or Game Launcher on Samsung).
2. For banking applications: take a photo of the screen with another phone (but be careful with confidential data!).
3. For instant messengers: disable Content protection in the application settings (if available).

⚠️ Attention: A Android 12+ restriction has appeared that prohibits screenshots in some applications. It is impossible to bypass it without root access. If the screenshot turns out black, this is exactly your case. FLAG_SECURE, which prohibits screenshots in some applications. It is impossible to bypass it without root access. If the screenshot turns out black, this is exactly your case.
