How to Troubleshoot Crashes, Freezes, and Poor Performance in Mobile Games

Identify whether a mobile game is crashing, freezing, stuttering, or lagging online, then work through low-risk fixes before trying steps that could erase data.

First identify whether the problem is an app crash, a freeze, choppy performance, or online lag: each points to a different cause. Then restart and update the game and device, check storage and requirements, and test the network if the issue is online. Save data-clearing, reinstalling, and factory reset for later because they can remove data.

Why does my mobile game keep crashing or freezing?

A crash means the game closes or returns to the home screen. A freeze means the picture or controls stop responding. Choppy animation is a performance problem; delayed actions or a dropped connection are more likely to involve network conditions. These distinctions matter: Riot Games Support treats a frozen game, a crashed app, and a game that will not download as separate problems in its Android mobile troubleshooting guide.

Note when the issue happens and whether it affects one game or several apps. Record the device model, operating-system and game versions, any error message, and whether the problem began after an update. This helps separate a title-specific fault from a broader device or connection issue.

What should I try first?

  1. Close and reopen the game. If it is unresponsive, close it using your device’s app-switching controls, then start it again. Apple explains how to close an unresponsive app in its slow iPhone or iPad troubleshooting guidance. Avoid force-closing apps routinely: Apple warns that doing so unnecessarily can slow a device because apps must reload their data.
  2. Restart the phone or tablet. Reopen the same game and repeat the action that triggered the problem. A restart is a low-risk first check recommended in official Android and Samsung troubleshooting guidance.
  3. Install available updates. Check the game’s official app-store listing, then check for an operating-system update in your device settings. Menu names vary by Android manufacturer and OS version; use the device maker’s instructions if you cannot find the update controls. Restart and retry after updating.
  4. Check free storage. Google says Android phones can start having issues when less than 10% of storage is free; see its Android device troubleshooting guidance. Apple recommends keeping at least 1 GB free on iPhone and iPad to avoid slowdowns. These are separate platform-specific recommendations, not interchangeable thresholds.
  5. Close background apps only if it is useful for the case. A game publisher may recommend this as a troubleshooting step, but closing every app is not a universal performance fix. Retry the same gameplay after closing any apps you choose to stop.

How do I stop lag in mobile games?

First distinguish a low frame rate from online latency. If animation looks uneven even in offline play, investigate device performance, compatibility, storage, software, or heat. If the game responds late, rubber-bands, or disconnects during online play, compare network connections before changing graphics or deleting data.

Yojaro 4Pack Silicone Suction Phone Case Mount, Silicon Adhesive Smartphones Stand Sticky, Hands-Free Phone Accessories Holder for Selfies and Videos (Black & White & Translucent & Light Pink)
  • 【Strong Adsorption】The inspiration of the silicone phone suction case comes from the adhesive force of the octopus. Each suction cup phone mount is 3.15 inches long and 2.17 inches wide, with 24 independent suction cups providing a stronger and more stable suction force, so you don't have to worry about your phone falling during use.
  • 【Back of Phone Suction Grip】Remove the adhesive film on the phone suction cup and stick it on the phone case. You can then fix the phone on any smooth surface, which is very convenient. (The phone suction cup cannot be removed and reused after being attached to the phone case. It is recommended to attach it to a regular phone case, not a valuable one.)
  • 【Widely Used】Our non-slip silicone phone sticky grip mount attaches to almost any flat phone case and make it compatible with common mobile phones such as iPhone and Android.You can shoot, watch videos or video calls in the kitchen, gym, dance studio, bathroom and other places.
  • 【Capture the Wonderful Picture】Whether you are a TikTok creator or just like to share videos and photos, this phone suction cup can help you hands-free capture wonderful videos and photos for sharing with friends.
  • 【Note】You can fix the phone suction cup on a smooth surface such as a mirror or glass. If necessary, wipe the suction cup with a damp cloth to obtain stronger suction. Before releasing your hand, make sure the phone is firmly fixed. (Not applicable to rough walls, wooden surfaces, and other uneven surfaces)

Test Wi-Fi, cellular service, and location

  • Try the same game action on Wi-Fi and cellular service, if available, and compare the result.
  • If you are moving, try again from one location. Apple notes that a device may reconnect as it moves between cellular towers, and that network congestion can slow apps even when the signal appears strong.
  • If connection problems persist, check network settings and contact the network administrator, internet provider, or mobile carrier. Google’s Android guidance for speeding up a slow device also recommends checking connection settings and seeking help from the relevant network provider when trouble continues.
  • If other online services work but only one game has trouble, check that game’s official support or service-status channel for a title-specific incident. The available information here does not establish a current outage.

Check the game’s requirements and temperature guidance

Compare your device with the affected game’s current minimum and recommended requirements; do not assume requirements for one title apply to another. For example, HoYoverse lists Tears of Themis Android minimums of a 64-bit ARM v8a processor, 4 GB RAM, and Android 6.0 or later; its recommended Android memory is 6 GB or above. Its page also lists title-specific iOS device, chip, memory, and OS requirements. See HoYoverse’s Tears of Themis troubleshooting and requirements.

That same page recommends Tears of Themis players use Smooth graphics, enable Low-Temp mode, make space, close other apps, update the OS, and avoid playing while charging. Treat these as advice for that game, not a guarantee that the same settings will improve every title or device.

Apple EarPods Headphones with USB-C Plug, Wired Ear Buds with Built-in Remote to Control Music, Phone Calls, and Volume
  • SUPERIOR COMFORT — Unlike traditional circular ear buds, the design of EarPods is defined by the geometry of the ear. Which makes them more comfortable for more people than any other ear bud–style headphones.

  • BUILT-IN REMOTE — EarPods with USB-C plug also include a built-in remote that lets you adjust the volume, control the playback of music and video, and answer or end calls with a pinch of the cord.
  • COMPATIBILITY — Works with all devices that have a USB-C port.
  • INTEGRATED MICROPHONE — A built-in microphone precisely captures your voice while you’re on the phone, taking a FaceTime call, or summoning Siri — so you’re always heard loud and clear.

What if only one game still crashes?

Use the game’s official support steps before making broad changes to the device. A game update, account-specific issue, or compatibility problem can affect one title while other apps work normally. If the game offers an in-app repair option, follow its instructions and confirm that your account progress is synced before taking steps that could remove local data.

When contacting support, include the device make and model, OS and game versions, exact error text, when the problem started, whether it followed an update, steps already tried, and whether it happens on another network or in other games. This gives support concrete details to distinguish a game-specific fault from a device or connection issue.

Which fixes risk losing game data?

Restarting and updating are less disruptive than clearing app data or reinstalling. On Android, manufacturer steps differ. Samsung describes clearing an app’s data as a possible reset, but warns that it erases app-stored data and may log you out; see its app-crash troubleshooting guide. Before clearing data or reinstalling, verify that your account is linked and progress is backed up or synced.

Android Safe mode temporarily disables downloaded apps and can help test whether one is associated with a wider device problem; the steps vary by manufacturer. It is more relevant when multiple apps misbehave than when only one game fails. A factory reset is a last resort, not a normal game fix: Google says it removes apps and their associated data. Back up the device before considering it, and use the manufacturer’s official instructions.
