Why online games crash on Android: a complete analysis of the reasons and solutions

You launch your favorite online game on your smartphone, 5-10 minutes of gameplay pass - and suddenly exits to the desktop. Or worse: the game freezes while loading, and then just closes without an error. Is this a familiar situation? Online game crashes on Android is one of the most common problems faced by gamers. There can be dozens of reasons: from a banal lack of RAM to hidden conflicts in the firmware.

In this article we will not just list the possible culprits of failures, but will analyze them from a technical point of view. You'll learn how to distinguish between hardware limitations and software bugs, why some games crash more often than others, and what to do if the problem only occurs on a specific device. And most importantly, get checklists and step-by-step guide for diagnosing and troubleshooting without flashing and going to the service center.

Spoiler: in 80% of cases it is not the “crooked hands” of the developers who are to blame, but the settings of your device. And this is good news - because you can fix most of the reasons yourself.

1. Overheating of the processor: why games “cut out” under load

The most obvious and common cause of crashes is thermal throttling (thermal throttling). When the chipset temperature exceeds a critical threshold (usually 85–90°C for Snapdragon or Mediatek), the system forcibly reduces performance or completely closes resource-intensive applications. Online games with their constant loading of textures and network requests come first.

How to understand that overheating is to blame?

• 🔥 The smartphone body becomes hot after 5-10 minutes of play (especially in the processor area).
• 📉 Performance drops sharply: FPS drops from 60 to 20–30, and then the game crashes.
• ⚡ The battery discharges unevenly: in 15 minutes of play it can “eat up” 10–15% of the charge.

Solutions depend on the device model. For most smartphones this will help:

• 🧊 Dust removal (especially relevant for devices with a removable back cover). Dust between the radiator and the chipset impairs heat dissipation by 30–40%.
• 🔄 Replacing thermal paste (for collapsible models). Over time, it dries out and loses its properties.
• 🛠️ Disabling background processes via Settings → Applications → Special access → Battery optimization.

⚠️ Attention: If the processor temperature exceeds 95°C during idle time (without games), this is a sign of a malfunction. There may be problems with the battery, power controller, or chipset itself. In this case, diagnostics in the service is required.

2. Lack of RAM: when Android "kills" games

Android actively manages RAM (RAM), and when it is not enough, the system begins to forcefully close background processes. Online games, with their constant network requests and texture caching, often fall victim to this mechanism. Especially on devices with 3–4 GB RAM.

How to check if there is enough memory?

• 📊 Open Settings → Memory and look at the usage graph RAM during the game.
• 🔍 Use applications like Game Bench or DevCheckto track the memory consumption of a specific game.

Optimization methods:

1. Disable autorun of unnecessary applications via Settings → Applications → Autorun.
2. Use "Game Mode" (available at Samsung, Xiaomi, Realme). It blocks notifications and background processes. Use "Game Mode" data-i="87">300–500 MB RAM
3. Close all applications before starting the game (even messengers like Telegram or WhatsApp can "eat" up to 300–500 MB RAM).

RAM volume	Recommended settings for games	Max FPS without crashes
3 GB	Close all background applications, graphics - "Low"	30
4 GB	Leave 1-2 background applications, graphics - "Medium"	45–60
6 GB+	You don't have to close instant messengers, graphics - "High"	60–90

⚠️ Attention: On some firmware (for example, MIUI or ColorOS), the system aggressively cleans RAM, even if there is enough memory. In this case, disabling the "Memory Optimization" function in the developer settings will help.

3. Conflicts with firmware: bugs of Android and manufacturers

Sometimes games crash due to errors in the firmware itself. This could be:

• 🐛 A bug in the Android kernel (especially relevant for beta versions).
• 🔧 Incorrect energy saving settings from the manufacturer (for example, Huawei or Xiaomi aggressively closing games in the background mode).
• 📦 Conflict with shell (for example, One UI from Samsung or EMUI from Huawei).

How to diagnose:

1. Check whether the game crashes on another device with the same firmware.
2. Read reviews on 4PDA or Reddit - users often complain en masse about bugs after updates.
3. Try to roll back to the previous firmware version (if you have a backup).

Solutions:

• 🔄 Reset the settings to factory settings (before that, make a backup!).
• 🛠️ Disable battery optimization for the game in the application settings.
• 📥 Install a custom kernel (only for advanced users!).

How to disable battery optimization for the game?

Go to Settings → Applications → [game name] → Battery and select the "No restrictions" or "Maximum performance" option.

4. Problems with the Internet: why games are “thrown out” due to networks

Online games require a stable connection, and the slightest interruptions can lead to crashes. Reasons:

• 📶 Unstable Wi-Fi (especially at frequency 5 GHz, which passes through walls worse).
• 📡 High ping (more 150 ms) due to an overloaded server or problems with the provider.
• 🔌 Switching between Wi-Fi and mobile network (if the "Auto switching" mode is enabled).

How to check the quality of the connection:

1. Run a speed test on Speedtest.net or Ookla.
2. Check ping to the game server using the command:

   ping

   (the address can be found on the game website or in the connection settings).

3. Disable the VPN (if you are using) - it can add delays.

Solutions:

• 🔄 Switch at 2.4 GHz (if you play via Wi-Fi and are far from the router).
• 📵 Disable auto-switching between Wi-Fi and mobile network in settings Android.
• 🛡️ Use a gaming VPN (for example, ExitLag or WTFast), if the problem is in routing.

⚠️ Attention: If the game crashes when connecting to the server, check whether it is blocked firewall (for example, in Avast or Kaspersky). Add the game to exceptions.

5. Outdated version of Android or drivers

Game developers optimize their products for the latest versions of Android and graphics drivers. If your device has not been updated for a long time, conflicts may arise:

• 🖼️ Outdated drivers Adreno (for Snapdragon) or Mali (for Mediatek/Exynos).
• 📱 Incompatibility with API (for example, the game requires Android 12, and you Android 10).
• 🔧 Bugs in older versions OpenGL or Vulkan.

How to update drivers:

1. Check system updates in Settings → System → Software update.
2. For Snapdragon: install the latest drivers Adreno via Google Play (application Adreno Driver Update).
3. For Mediatek/Exynos: driver updates come only with firmware.

Critical information: On some devices (for example, Samsung Galaxy S20 on Exynos 990updating drivers Mali may lead to artifacts in games. Before updating, check reviews on thematic forums.

💡

If the game. requires a new version of Android, but there are no updates for your device, try installing custom firmware (for example, LineageOSBut remember: this will void the warranty!

6. Viruses and malware: hidden threats

Malware can not only steal data, but also interfere with operation. games:

• 🦠 Miners (hiddenly use processor resources to mine cryptocurrency).
• 🕵️ Keyloggers (may conflict with game anti-cheats).
• 📦 Fake APK (if you have not downloaded the game from Google Play).

How to check the device:

1. Install an antivirus (Malwarebytes or Dr.Web) and scan the system.
2. Check the list installed applications for suspicious ones (Settings → Applications → All applications).
3. Open Settings → Battery and see which applications consume a lot of energy in the background.

If you find a virus:

• 🚫 Remove suspicious ones applications.
• 🔄 Reset to factory settings (if the virus is deep in the system).
• 🛡️ In the future, install games only from official sources.

7. Conflicts with other applications

Sometimes games crash due to conflicts with:

• 🎵 Music players (for example, Spotify or YouTube Music can block the audio stream of the game).
• 📱 Overlays (for example, Facebook Messenger or Discord with floating windows).
• 🔧 Overclocking applications (for example, Game Booster or CPU Tuner).

How to find the culprit:

1. Start the game in safe mode (hold the shutdown button → "Safe Mode") If the game does not crash, the problem is in one of the installed applications.
2. Disable background services one by one through Settings → Applications → Running.

💡

Safe mode disables all third-party applications, leaving only system ones. If the game runs stably in it, look for a conflict. among the installed software.

8. Hardware faults: when the hardware is to blame

If none of the above helped, the problem may be in the hardware:

• 🔋 Worn out battery (if it is swollen or its capacity has dropped below 70% from the nominal, the device may turn off spontaneously).
• 💾 Damaged memory (bad sectors on the internal drive).
• 🔌 Faulty power controller (can cause abrupt reboots).

How to diagnose:

• Check the battery status via AccuBattery or ##4636## (testing menu).
• Scan the memory for errors using SD Maid or DiskDigger.
• If the smartphone turns off under load, this is a sign of power or overheating problems.

⚠️ Attention: Details Hardware diagnostics may vary depending on the device model. For an accurate analysis, use the manufacturer's official utilities (for example, Samsung Members or Xiaomi Service Tool).

FAQ: Frequently asked questions about game crashes on Android

Why does the game crash when loading?

Most likely, the problem is:

• Lack of RAM (the system "kills" the game when trying to load textures).
• Damaged cache files (try clearing the game data in Settings → Applications).
• Conflict with the antivirus (disable it temporarily launch).

The game works on Wi-Fi, but crashes on the mobile data. Why?

Probable reasons:

• The operator is blocking the ports used by the game (try turning on the VPN).
• Unstable connection (check the signal level in settings of the SIM card).
• Traffic limits (some operators throttle the speed after exceeding the limit).

Is it possible to fix crashes without root access?

Yes, in most cases Root is only needed for:

• Removing system ones. applications that conflict with the game.
• Manually adjusting the processor/GPU frequencies.
• Installing custom kernels or firmware.

All other methods (clearing the cache, setting up the network, updating drivers) work without root.

Why do games crash more often on a new smartphone than on an old one?

Paradox, but this is possible due to:

• More aggressive battery optimization in new versions of Android.
• High screen resolution (new smartphones often have FHD+ or QHD+, which increases the load).
• New chipsets with unoptimized drivers (especially relevant for Mediatek Dimensity or Exynos).

How to return progress if the game crashes and is not saved?

Recovery methods:

• Check whether the account is linked to Google Play Games or a social network (progress is often synchronized automatically).
• If the game supports cloud saves, reinstall it and log into your account.
• For offline games, try restore data from a backup (if it is in Settings → Google → Backup).
