Help

I’m having a big freaking problem for days, it is driving me nuts… I am developing a 2D game(snakes and ladders)for Android using Godot, and I am experiencing an issue where some of my UI buttons do not respond to touch on certain Android devices.

Project Information

  • Version: Godot 4.6.3 stable (official)
  • Programming Language: GDScript
  • Target Platform: Android
  • Game Type: 2D
  • Orientation: Landscape
  • Designed Resolution: 1280×720

For the main UI buttons, I am using the standard Godot Button node.

The main buttons on my menu include:

  • SettingButton
  • ShopButton
  • RulesButton
  • CharacterButton
  • StartButton

I also use a TextureButton inside one of my popups.

The main scene structure is approximately:

mainmenu
├── Menu (Sprite2D)
├── SettingButton (Button)
├── ShopButton (Button)
├── RulesButton (Button)
├── Label
├── CharacterButton (Button)
├── StartButton (Button)
├── coinbutton
├── CoinLabel
├── FeatherLabel
├── Timer
└── NoFeatherPopup
    ├── DarkBG
    ├── NoFeatherCard2
    └── TextureButton

The Problem

The problem is that the buttons do not respond correctly to touch on some Android devices.

I am running the game on the phones through USB Debugging / Debug over USB from Godot.

These are the test results:

Device / Environment Result
Running the game inside Godot on my laptop :white_check_mark: Buttons work
One Android phone belonging to a team member :white_check_mark: Buttons work
My Android phone :cross_mark: Buttons do not work
Three other Android phones belonging to team members :cross_mark: Buttons do not work

We are a team of five people. In total, the problem occurs on 4 out of 5 phones. Only one Android phone is working correctly.

Therefore, the issue does not appear to be specific to a single phone.

Settings I Have Already Checked

I checked the Inspector settings of the buttons.

For the main buttons:

Mouse Filter = Stop
Behavior = Inherited

I also have the following option enabled in Project Settings:

Emulate Touch From Mouse

Despite these settings, the problem still occurs on several Android devices.

Possible Causes

I am not sure what is causing the issue. It may be related to:

*Different screen resolutions or aspect ratios

*UI scaling, Viewport, Stretch, or Content Scale settings

*The actual clickable area or position of the Button

*Another Node overlapping the buttons

*Android touch input behavior or device-specific differences

My Questions

What should I check to identify the cause of this issue?

Is there any specific Godot 4.6.3 setting related to Button, TextureButton, touch input, Viewport/Stretch, UI scaling, or clickable areas that I should check?

Also, is there a recommended way to debug this on an Android device and see the actual clickable area of a Button and which Node is receiving the touch input?
