Are you tired of blurry images in your favorite mobile games? Even on modern smartphones, the default graphics settings are often lowered to save battery power and ensure stable FPS. But what if you're willing to sacrifice a couple of hours of battery life for crystal clear images? In this article we will look at 7 proven ways to increase the resolution in games on Android from basic settings to hidden functions for advanced users.

It is important to understand: not all games support manual resolution adjustment. In some cases (for example, PUBG Mobile or Call of Duty: Mobile), developers limit the maximum quality depending on the device model. However, even on budget phones you can get more out of it if you know where to look. We will also tell you how to bypass restrictions and what to do if the game automatically resets its settings after an update.

We warn you in advance: increasing the resolution increases the load on the processor and video accelerator. On weak devices this can lead to FPS drops, overheating or rapid battery discharge. If your smartphone is older than 2-3 years, first check it for performance in benchmarks (for example, 3DMark or GFXBench).

1. Graphics settings inside the game: where to look and what to change

The first thing you need to do is look at the settings menu of the game itself. In most modern projects (especially in shooters and MMORPGs) There is a separate section for graphics. Usually it is called Graphics, Video Settings or Display. Here is what you can configure there:

  • 🎮 Resolution: select the maximum available (for example, 1920×1080 instead of 1280×720may be displayed as "HD", "FHD"). or "Ultra HD".
  • 🖼️ Texture Quality: is responsible for the detail of objects. Optimally - "High" or "Ultra".
  • 🌿 Effects: includes shadows, reflections and particles. It is better to leave it on weak phones. on "Medium".
  • 🔄 Frame rate (Frame) Rate): if available, choose 60 FPS or 90 FPS, but remember that this drains the battery a lot.

In games from Tencent (for example, PUBG Mobile or Call of Duty: Mobile) there is an additional parameter - Graphics Style. Here you can choose between "Balanced", "HD" and "Smooth". data-i="66">, but be prepared for increased load. HD, but be prepared for increased load.

⚠️ Attention: In some games (for example, Genshin Impact) high resolution is automatically blocked on devices with low RAM. If the option is grayed out, try closing background applications or using the methods in the following sections.

Close all background applications

Connect the charger (for long sessions)

Check the free space on the device (at least 2-3 GB)

Disconnect energy saving mode -->

2. Using Game Booster and Game Mode: hidden Android functions

Many smartphone manufacturers build special modes for gamers into their shells. They not only optimize performance, but also allow you to manually set the resolution for games. Here's how it works on popular brands:

  • 📱 Samsung (Game Launcher): Open Game Launcher, select the game → click on the three dots → Game Booster Plus → Resolution. Here you can force install FHD+ or WQHD+.
  • 📱 Xiaomi (Game Turbo): Go to Settings → Accessibility → Game Turbo, select the game and activate the option High resolution.
  • 📱 ASUS (Armoury Crate): In the game menu, enable Performance Mode and set the maximum resolution to Display Settings.
  • 📱 Realme/Oppo (Game Space): Open Game Space, select the game → Gaming Tools → High-Res Mode.

On "pure" Android (for example, on Google Pixel) there are no such functions, but you can use third-party utilities like Game Tuner or GFX Tools (we'll talk about them later). Also, some games (for example Fortnite or Apex Legends Mobile) have a built-in Performance Mode, which automatically adjusts the resolution to the hardware.

⚠️ Attention: On devices with MediaTek processors, a forced increase in resolution through Game Mode may cause image artifacts. If you notice flickering or blurriness, return the settings to standard.
Brand Function name Max. supported resolution Features
Samsung Game Booster Plus WQHD+ (3200×1440) Works only on flagships (S22 Ultra, S23+)
Xiaomi Game Turbo FHD+ (2400×1080) Requires activation in developer settings
ASUS ROG Armoury Crate 4K (3840×2160) Supports external monitors
Realme Game Space FHD+ (2400×1080) Automatically turns off when the battery is low

3. GFX Tools and other utilities for forcing resolution changes

If the built-in tools do not give the desired result, third-party applications come to the rescue. The most popular is GFX Tools for [Game Name] (there are separate versions for PUBG, COD, Free Fire etc.). These utilities allow you to bypass game limitations and set custom graphics settings, including resolution, FPS and level of detail.

How to use GFX Tools:

  1. Download the version for your game (for example, GFX Tool for PUBG) from Google Play or the official website.
  2. Run the utility and select the desired game from the list.
  3. In the section Resolution set the maximum value (for example, 1920×1080 or 2560×1440).
  4. Activate the option 60 FPS (if supported).
  5. Click Apply and run the game through GFX Tools.

Other useful utilities:

  • 🛠️ Game Guardian: Allows you to change graphic parameters on the fly, but requires root access.
  • 🖥️ Octopus: Keyboard and mouse emulator with the ability to fine-tune the resolution.
  • 🔧 GLTools: For advanced users - changes OpenGL settings at the system level (requires root).
⚠️ Attention: Using GFX Tools and similar utilities can be considered cheating in multiplayer games. In PUBG Mobile and Call of Duty: Mobile your account is blocked for this. To avoid bans, do not change the settings associated with Anti-Aliasing or Hitbox.
💡

If the game crashes after using GFX Tools, try reducing the resolution by 1 step (for example, from 1080p to 900p) or disable the option Force OpenGL ES 3.2 in the utility settings.

4. Changing resolution through developer settings

Android hides many useful features in the developer menu. One of them is the ability to force permission for individual applications. Here's how to do it:

  1. Activate developer mode: go to Settings → About phone and tap 7 times on Build number.
  2. Go back to the main settings menu and find the new section For Developers.
  3. Scroll down and find the option Minimum width (dp) (Smallest width).
  4. Set the value 480 for 720p, 600 for 1080p or 720 for 1440p.
  5. Reboot the device.

This method does not work in all games, but it may help if the game automatically lowers the resolution on your device. For example, in Genshin Impact after a change Smallest width sometimes an option appears 60 FPSeven if it was not there before.

Another useful parameter in the developer settings is Disable absolute volume (Disable absolute volume). Enabling it may improve the sound in games, but this does not apply to resolution.

⚠️ Attention: Incorrect values ​​in Smallest width can lead to crashes in the Android interface. If, after the changes, applications begin to be displayed incorrectly, return the value to 0 (default) and restart the phone.
What to do if there is no Smallest width option?

On some firmware (for example, MIUI or ColorOS) this parameter may be called Minimum width or hidden in the section Drawing. If it is not there at all, try using the ADB command:

adb shell settings put global forced_resolution 1920x1080

But remember that this may break the display of system applications!

5. Using ADB commands for advanced users

If you are not afraid of the command line, ADB (Android Debug Bridge) will open up new opportunities for you to configure resolution. This method requires connecting the phone to a PC, but allows you to bypass many restrictions.

Instructions:

  1. Download Platform Tools from the official website Android Developers and unpack the archive.
  2. Enable on your phone USB debugging in the developer settings.
  3. Connect your phone to the PC and open the command line in the folder with Platform Tools.
  4. Enter the command to check the connection: 
    adb devices

    Your serial number should be displayed device.

  5. Set the desired resolution (for example, 1080p): 
    adb shell wm size 1080x2340

    (replace 2340 with the height of your phone screen).

  6. Fix the changes: 
    adb shell wm density 480

To return the standard resolution, use:

adb shell wm size reset

This method works even on devices without root access, but after a reboot the settings will be reset. To make the changes permanent, you will need to create a script or use Tasker.

⚠️ Attention: On some devices (especially with Exynos processors), forcing a resolution change via ADB may lead to artifacts in games. compatibility on forums (for example, XDA Developers or 4PDA).

6. Root methods: maximum graphics customization

If you are ready to take radical measures, root access will open full control over graphic settings. With it you can:

  • 🔧 Change the resolution at the GPU level (via Build.prop or Kernel Adiutor).
  • 🎯 Unlock hidden settings in games (for example, Ultra HD on PUBG on unsupported devices).
  • 🔄 Install custom drivers for the video chip (for example, Adreno Tuner for Qualcomm).
  • 🛡️ Disable FPS restrictions imposed manufacturer.

One of the most popular tools is GLTools (requires root). It allows you to:

  • Emulate another device (for example, Samsung Galaxy S22) to bypass restrictions.
  • Force anti-aliasing. (Anti-Aliasing) and anisotropic filtering.
  • Change the render resolution regardless of the screen resolution.

Example settings GLTools for Genshin Impact:

  1. Open GLTools and select Genshin Impact in the list of applications.
  2. In the section Resolution install 1920×1080 (even if the phone screen is smaller).
  3. Activate Force AA and select 4x MSAA.
  4. B Device Settings emulate Adreno 650 (for maximum compatibility).
  5. Save the profile and run the game.
⚠️ Attention: Using root methods may void your warranty, unstable operation of the system or even a “brick” of the device. Before experiments, make a full backup via TWRP or OrangeFox.
💡

Root access gives maximum freedom of configuration, but requires technical knowledge. If you are not confident in your abilities, it is better to use methods without root (GFX Tools or ADB).

7. Performance optimization: how to avoid it. lags at high resolution

Increasing resolution is always a compromise between picture quality and performance. To prevent the game from slowing down, follow these tips:

  • ⚡ Close background applications: Use Settings → Applications → Runningto stop unnecessary processes.
  • ❄️ Device cooling: For long sessions, use a cooling pad or fan. Overheating above 45°C leads to throttling (automatic lowering of processor frequencies).
  • 🔋 Energy saving: Disable Adaptive battery i Application optimization in the settings power supply.
  • 📶 Network: In online games use 5 GHz Wi-Fi or 4G/5Gto avoid delays.

You can also use optimization utilities:

  • 🛠️ Greenify: "Freezes" background processes, freeing up resources for the game.
  • 🔄 SetCPU (requires root): Allows you to manually set processor frequencies for maximum performance.
  • 🧹 SD Maid: Clears cache and junk files that can slow down the system.

If even after optimization the game lags, try lowering the resolution by one level, but increasing FPS. For example, 1280×720 at 60 FPS will look smoother than 1920×1080 at 30 FPS.

💡

In games with support Vulkan API (for example, PUBG Mobile or Call of Duty: Mobile) enable this mode in the graphics settings. Vulkan gives a 10-20% increase in FPS compared to OpenGL.

FAQ: Frequently asked questions about resolution in Android games

Is it possible to increase the resolution above the native screen resolution?

Technically yes, but it makes no sense. For example, if your screen has a resolution 2400×1080, installing 4K will not improve the picture, but will only increase the load. The exception is games that support dynamic resolution (for example, Genshin Impact), where rendering can occur at a higher resolution followed by downscaling.

Why is there no option in the game to change the resolution?

This may be due to:

  1. Hardware limitations (weak processor or little RAM).
  2. Developer policy (for example, Free Fire fixed resolution).
  3. Regional settings (in some countries, graphics options are blocked).

Try to use GFX Tools or change the region in the Google Play settings.

Will there be a ban for changing the resolution through GFX Tools?

In most games - no, unless you change parameters related to gameplay (for example Hitbox or Aim Assist). However, you may be banned for using GFX Tools if the system detects changes in the graphics config. To reduce risks: PUBG Mobile And Call of Duty: Mobile You may be banned for using GFX Tools if the system detects changes in the graphics config. To reduce risks:

  • Do not use "cheat" presets (for example, "No Grass" or "Transparent Walls").
  • Do not change FPS higher 60 (if the game does not support 90/120 FPS officially).
  • Periodically return the settings to standard.
How to return the standard resolution if the game does not start after the changes?

If the game crashes or displays incorrectly:

  1. Delete the game cache in Settings → Applications → [Game name] → Memory → Clear cache.
  2. If you used GFX Tools, reset the settings in it or delete the game profile.
  3. For ADB changes, run the command: 
    adb shell wm size reset
  4. If all else fails, reinstall the game.
Which resolution is best to save battery?

Optimal balance between quality and autonomy:

  • 1280×720 (HD) + 30 FPS - minimum consumption.
  • 1600×900 + 40 FPS —the gold standard for most games.
  • 1920×1080 (FHD) + 60 FPS —only for flagships with a 5000+ mAh battery.

Also turn off Shadows i Particle effects —they drain a lot battery, but have almost no effect on gameplay.
