Android & iOS Problems

Game crashes

Reason 1: GPU acceleration on some devices causes crashes.

• Solution: Disable GPU Acceleration in the settings.

Reason 2: Your device does not have enough RAM (less than 3 GB).

• Info: You can first check supported iPhones and iPads out. Unsupported Android devices are already filtered out by Google Play Store.
• Solution: Restart the device and disable Load Sound Banks in GnollHack's settings (you will hear no audio, then, though).​

Game starts with a dark gray GnollHack logo but then the main screen does not appear (except maybe for the background)

Reason: You have disabled animations.​

• Fix 1: (Samsung Galaxy phones and tablets) Go to Android's Settings → Accessibility → Visibility Enhancements and disable Remove Animations.

• Fix 2: Go to Android's Settings → (System) → Developer options and set:​

  • Window animation scale to 1x
  • Transition animation scale to 1x
  • Animator duration scale to 1x

  If you do not have Developer options enabled, you can follow these instructions to get them enabled, even though in that case it is unlikely that these settings are not at their default values. Note that the location of Developer Options varies by phone, so that it sometimes is in the root level of the settings and sometimes under Settings → System.​

Saved games have become incompatible

Reason: You have upgraded the installation to an incompatible version.

(This may be caused by auto-update.)

• Fix: Downgrade your GnollHack installation.
  • Android: Android Releases
  • iOS: iOS Releases
• Pre-emptive fix: To prevent this happening in the future, please disable auto-update.
  • Android: Go to Google Play Store → GnollHack and click three dots in the right top corner and disable Enable auto udate.
  • iOS: Go to Settings → App Store and disable App Updates.

GnollHack is killed while on the background

Reason: You have not disabled battery optimization for GnollHack

Android

• Fix 1: Go to Settings → Apps → GnollHack → Battery and set it to Unrestricted.
• Fix 2: Plug your device into power.
• Test Results: It's been tested on Samsung Galaxy A52s that the game is not killed within the first 10 minutes while on the background, when using the Unrestricted battery optimization mode. However, the game is in danger to be killed after that time due to excessive CPU usage.
