Severe freeze bug-drag image in WebView freezes entire UI (Android 8.1, Chrome 131+)

[ttt 444]

Hi Android WebView devs,

I’d like to report a severe freeze bug that affects my old Android 8.1 phone (Vivo 1811).

I’m not technical, but here’s what I’ve confirmed:

---

Device: Vivo 1811

Android version: 8.1.0

Chrome version where bug happens: 131.x and above

Chrome version where bug does NOT happen: 130.0.6723.103 and below

WebView: Forced to use Chrome (can’t be changed on this device)

---

Bug details:

When using any app that shows a webpage inside it (like some browsers or games that use WebView), if I long-press an image, the image becomes “floaty” and moves with my finger like it’s draggable.

When I lift my finger, the image freezes in place - and the entire screen becomes unresponsive.

The only things that work are the power and volume buttons. The frozen image stays stuck even on the lockscreen after turning the screen off and on.

The only fix is to force reboot by holding Power + Volume Down.

This happens in multiple apps that use WebView - for example:

* The 1DM browser (not Chrome)

* The ChatGPT mobile app

* A rhythm game that opens a profile page in a WebView: if I long-press the profile picture, same bug happens.

Important:

* The bug does not happen inside the Chrome app itself - only in other apps using WebView.

* Downgrading Chrome back to version 130 fixes it completely.

* Updating to any version above 131 brings the bug back.

Video proof:

Here’s a Google Drive link showing the bug:

Steps to reproduce:

1. Open any app that uses WebView.

2. Open any image in it and long-press it.

3. The image floats with your finger.

4. Release it.

5. The entire screen freezes-touch input is dead, only Power + Volume buttons work.

Extra notes:

* Even the fingerprint sensor works: I can pull down the notification bar by swiping the sensor, but nothing else responds.

* ChatGPT says this is probably a drag-and-drop regression in the Chromium WebView layer.

I hope someone can check this out - it’s scary because it locks the whole device with no way to tap anything.

Thank you for reading!
