First identify whether the game is crashing, freezing, running at a low frame rate, or having an online connection problem. These symptoms have different causes, so try low-risk checks—restart, update, check storage, and compare networks—before clearing data or resetting the device.

Why does my mobile game keep crashing or freezing?

A crash usually means the game closes and returns you to the home screen. A freeze means the picture or controls stop responding. Choppy animation points more toward performance, while delayed actions or disconnections often point toward the network. Riot Games separates a frozen game, a crashed app, and a game that will not download as different problems in its Android mobile troubleshooting guidance.

Before changing settings, note the game, device model, operating-system version, game version, exact error message, and when the problem started. Record whether it began after an update and whether other games or apps are affected. This helps distinguish a game-specific fault from a device-wide issue.

What should I try first?

  1. Close and reopen the game if it is stuck. If it remains unresponsive, restart the phone or tablet. On Apple devices, follow Apple’s steps for closing an unresponsive app. Avoid force-closing apps routinely: Apple notes that unnecessary force-closing can slow the device because apps must reload their data when opened again.
  2. Install available updates. Check the game’s official app-store listing for an update, then check the device’s system settings for an operating-system update. Menu names and update paths vary by Android manufacturer and software version. Google’s Android troubleshooting guidance and Samsung’s app troubleshooting steps both include update checks.
  3. Check free storage. Google says Android phones can start having issues when less than 10% of storage is free. Apple recommends keeping at least 1 GB free on iPhone or iPad to avoid slowdowns. These are separate platform-specific support recommendations, not interchangeable thresholds. See Google’s Android guidance and Apple’s iPhone and iPad guidance.
  4. Retry the same action. After each change, reopen the game and repeat the step that caused the problem. Changing one thing at a time makes it easier to tell what helped.

How do I stop lag in mobile games?

If the animation is choppy

Choppy movement or delayed screen rendering can indicate low frame rate or device performance trouble rather than an internet issue. Close other apps only as a targeted test, especially if the game publisher recommends doing so; routinely force-closing every app is not a guaranteed fix. Check whether the phone is hot and compare performance after it has cooled. Then check the game’s current device and operating-system requirements: a game may run poorly or fail on hardware it does not support.

Requirements are specific to each title.

Those figures apply to that game, not mobile games generally. Consult the game’s own support page for its current requirements.

If actions are delayed or the game disconnects

Compare the same in-game action over Wi-Fi and cellular service, or try another location. If responsiveness changes, the network path may be contributing. A strong signal does not rule out congestion: Apple notes that network congestion can slow apps, and a moving device may reconnect as it switches cellular towers. Google’s Android guidance for slow devices and connection problems recommends checking connection settings and contacting the network administrator, internet provider, or mobile carrier if trouble persists.

If other online services work but one game does not, check that game’s official support or status channel for a title-specific problem. These symptoms alone do not establish that a current outage is occurring.

Why is my phone slow only when I play games?

A demanding game can expose limited free storage, device compatibility limits, background activity, heat, or an app-specific bug that is not noticeable in lighter tasks. Check the game’s published requirements against your exact device, and see whether the slowdown starts after a particular update or during a particular scene. If the phone is hot, stop playing until it cools rather than continuing to test under the same conditions.

Its support instructions also describe a repair tool on the login screen. These are recommendations for Tears of Themis; they do not guarantee a fix on every phone or apply to every game.

What can I try next on Android or iPhone?

Android

Android settings and menu labels differ across manufacturers and versions. If multiple apps are malfunctioning, Android’s safe mode can temporarily disable downloaded apps and help test whether one is associated with a broader device problem; use the device maker’s instructions because the steps vary. If only one game fails, start with that game’s official support steps.

Clearing an app’s data is more disruptive than restarting or updating. Samsung warns that clearing data erases app-stored data and may log you out. Before doing it, confirm that progress is synced to the game’s account or cloud service and that you can sign back in. Samsung’s app troubleshooting guide explains its device-specific options.

iPhone and iPad

Use Apple’s storage, app, and device guidance rather than Android menu instructions. If the game remains unresponsive, close it and reopen it, then restart the device and check for app and iOS or iPadOS updates. Apple also recommends keeping at least 1 GB of storage available to avoid slowdowns. Its slow iPhone and iPad guidance covers these checks.

When should I reinstall or reset the device?

Escalate gradually: confirm the issue, update, restart, check storage and network, then use the game’s own repair or support instructions. Reinstalling or clearing data can remove local progress or settings, so first verify account or cloud sync and confirm you know the login details.

A factory reset is an advanced last resort, not a normal first step for one game’s problem. Google’s Android guidance says a factory reset removes apps and their associated data. Back up important data before considering it, and use the device maker’s instructions.

What information should I send game support?

Include the device make and model, operating-system and game versions, the exact error text, when the fault began, whether it followed an update, and the steps you have already tried. Also say whether the issue happens in other apps or games and whether it changes on another network. These details help support teams narrow down whether the fault is specific to the title, device, or connection.
