Video does not play on Android: reasons and solutions (2026)

Are you trying to open a video on your smartphone, but instead of a picture you see a black screen, a “Could not play” error, or endless loading? The problem is familiar to millions of users, from budget ones to flagship ones. The reasons may lie in both software failures (90% of cases) and hardware failures. In this article we will look at Android - from budget Xiaomi Redmi to flagship Samsung Galaxy S24. The reasons may lie in both software failures (90% of cases) and hardware failures. In this article we will analyze all possible scenarios from basic settings to hardware diagnostics.

Important: solutions differ depending on video format (MP4, MKV, AVI), source (YouTube, local files, streaming services) and device model. For example, without Google services, videos with DRM protection may not work, and older ones often lack codecs for Huawei Without Google services, videos with DRM protection may not work, and on older ones Sony Xperia often there are no codecs for H.265/HEVC. We have structured the instructions so that you can quickly find a solution to your situation.

1. Checking basic parameters: Internet, sound, brightness

Start with the obvious - sometimes the problem lies not in the video, but in the smartphone settings. In 30% of cases, users simply forget to turn on the sound or reduce the screen brightness to zero, which makes it seem like the video is not playing.

• 📶 Internet connection: Open the browser and check the speed on speedtest.net. For video in 1080p requires at least 5 Mbit/s, for 4K - from 20 Mbit/s. If the speed is low, switch from Wi-Fi to mobile data or vice versa.
• 🔊 Sound and media: Press the volume buttons during playback. Check to see if Silent mode is activated in the notification shade. Some Samsung have a separate slider for media - it's worth checking that too.
• 🌞 Screen brightness: Swipe down from the top edge of the screen and move the brightness slider. On Xiaomi i Realme automatic adjustment may work - disable it in Settings → Display.
• 🔄 Reboot the device: Close all applications and restart the phone. This will clear temporary OS errors that may block playback.

⚠️ Attention: If the video does not load in only one application (for example, TikTok or YouTube), the problem may be in the platform servers. Check the status of the service on Downdetector.

2. Updating applications and codecs

Android uses software codecs to decode video. If the codec is outdated or missing, the video will either not open or will play without sound/picture. Especially relevant for formats MKV, FLV or videos with rare resolutions (for example, 1440p on older devices).

Update the applications first:

1. Open Google Play Market.
2. Click on the profile avatar → Manage applications and device.
3. Select Update all or find a specific application (for example, MX Player, VLC) and update it manually.

If the video still does not play, install a universal player that supports all codecs:

• 🎬 VLC for Android - supports H.265, VP9, AV1 and DRM.
• 📺 MX Player - optimized for Android, has built-in codecs for AC3 i DTS (need to be downloaded additionally in the player settings).
• 🌐 Kodi - suitable for streaming and local files with rare formats.

Video format	Required codec	Supported player
MP4 (H.264)	Built-in Android	Any standard player
MKV (H.265/HEVC)	libhevc or libx265	VLC, MX Player (with additional codecs)
AVI (DivX/Xvid)	libavcodec	MX Player, BSPlayer
WebM (VP9)	libvpx	VLC, browser Chrome

3. Clearing cache and application data

A clogged cache or damaged application data is a common cause of playback failures. For example, YouTube temporary files may accumulate that conflict with new versions of the video. Cleaning helps in 40% of cases when videos do not load in only one application.

Instructions for Android 12+:

1. Go to Settings → Applications.
2. Select the problematic application (for example, Gallery, YouTube, Chrome).
3. Click Storage → Clear cache.
4. If that doesn’t help, press Clear data (⚠️ this will delete all settings and inputs!).

For system applications (for example, Google Play Services) the path may be different:

Settings → Applications → Show system → Google Play Services → Storage → Clear cache

⚠️ Attention: Clearing data in Google Play Services may cause temporary disruptions in other applications. procedures, reboot the device.

Remember the login/password for your account in the application

Close the application through the "Recent" menu

Check the free space in memory (you need at least 500 MB)

Make a backup copy of important data (for some applications)-->

4. Problems with DRM and protected content

Videos from DRM protection (for example, movies from Netflix, Kinopoisk or Disney+) require special certification of the device. If your smartphone has not passed the verification Widevine L1, the video will be played in low resolution or will not open at all. The problem is typical for:

• 📱 Devices without services Google (for example, Huawei after 2019).
• 🛠️ Smartphones with custom firmware (LineageOS, Pixel Experience).
• 🔓 root access (even if they have been deleted, a trace may remain in the system).

How to check the level Widevine:

1. Install the application DRM Info from Google Play.
2. Open it and find line Widevine CDM.
3. If specified L3 —video in Full HD and 4K will not be played. L1 —full support.

Solutions:

• 🔄 Update Google Play Services and Google Play Protection manually via APKMirror (if the update is not available in Play Market).
• 📥 Install Magisk and module Widevine L1 Fixer (only for root devices).
• 🛒 Buy a device with official support Widevine L1 (list available on website Google).

Why doesn't Netflix work on Huawei in 4K?

Huawei lost its license for Google services after sanctions in 2019. New models (for example, Mate 50 Pro) use their own ecosystem HMS, which is not certified for Widevine L1. Netflix and other services forcefully lower the resolution to 480p or block playback.

5. Hardware problems: display, speakers, battery

If the video does not play in all applications, including the gallery and browser, the reason may be in hardware. Typical symptoms of hardware failures:

• 🖥️ The screen blinks or shows artifacts (stripes, spots) when you try to open a video.
• 🔇 There is sound, but there is no picture (or vice versa).
• 🔋 The phone turns off during playback (problem with the battery or power controller).

Diagnostics:

1. Test. display: Start the video and shine a flashlight on the screen at an angle. If the image is barely visible, the backlight has burned out.
2. Checking the speakers: Connect headphones. If there is sound, the problem is in the speaker or cable.
3. Battery diagnostics: Install AccuBattery and check the battery condition. If the capacity is below 70%, replace the battery.

Symptom	Probable cause	Solution
Black screen, sound yes	The backlight is burned out or the display cable is damaged	Replacement of the screen at the service center
Video lags, the phone gets warm	GPU overload or throttling due to overheating	Cleaning dust, replacing thermal paste
Sound is interrupted, video slows down	Problems with RAM	Test RAM in CPU-Z, in case of errors - repair

⚠️ Attention: If the phone has been dropped or wet, do not try to disassemble it yourself - this may lead to a short circuit. Contact a service center with diagnostic equipment.

6. Problems with the firmware and system kernel

After updating Android or installing custom firmware, codecs, display drivers or modules Widevinemay disappear. For example, on Samsung after updating to One UI 6 users massively complained about the lack of sound in the video. In such cases, it helps:

• 🔙 Roll back update: Go to Settings → System → Update Software and select Cancel last update (not available on all devices).
• 📦 Flashing: Download the official firmware for your model from the manufacturer's website (for example, Xiaomi — mi.com, Samsung — samfw.com) and install it via Fastboot or Recovery.
• 🐧 System kernel: If the video slows down after flashing the firmware, check the kernel version in Settings → About phone → Kernel version. For Qualcomm must be at least 4.19, for Mediatek — 5.4+.

For advanced users:

adb shell getprop ro.build.version.incremental # Checking the build
adb shell dumpsys media.codec --list # List of available codecs
adb shell dumpsys media.drm # Widevine status

7. Alternative playback methods

If the video does not open using standard methods, try workarounds:

• 🌐 Streaming via browser: Upload the video to Google Drive and open it through the browser Chrome in “For Computer” mode (there is a corresponding option in the browser menu).
• 🖥️ DLNA/UPnP: Install on your phone BubbleUPnP and stream the video to Smart TV or Chromecast. This will take the load off the smartphone's processor.
• 📁 Conversion formats: Use HandBrake (on PC) or Video Converter Android (on phone) to convert video to MP4 (H.264 + AAC) —the most compatible format.
• 🔌 OTG cable: Connect the phone to the TV via USB-C → HDMI adapter and play the video on the big screen.

For owners Samsung DeX:

1. Connect the phone to the monitor via DeX Station.
2. Open the video in DeX mode - this uses additional processor resources.

8. When to contact the service center

If you have tried all the methods, but the video still does not play, the problem may be:

• 🔧 Damaged memory chip (for example, after a fall or overheating).
• 🖲️ Faulty graphics accelerator (artifacts on the screen, lags in games).
• 🔌 Oxidized contacts (if the phone got wet).

Signs that repair is needed:

• Video does not play even after a factory reset settings.
• The phone turns off when you try to open the video.
• Colored stripes or flickering appear on the screen.

⚠️ Attention: If the warranty is still valid, do not open the case yourself! Manufacturers (for example, Samsung or Xiaomi) will void the warranty if there are signs of tampering.

FAQ: Frequently asked questions
