Why is my Signal QR code not working?

How do I transfer my Signal to my new Android phone?

I upgraded my Signal to a new Android phone (Samsung Galaxy Note 4) over the weekend, and can't access my Signal. The connection information is still there on my old phone, but I can't figure out how to get the old version of the app to run on my new phone. Does anyone have any ideas how to do this?

Open the app settings in the Google Play store on your old phone and disable the old signal app from being reinstalled when you update your software. This will prevent the app from being updated while it's running on your old phone.

Open up the app settings in the Google Play store on your new phone and click on uninstall under the signal app. It will uninstall the signal app, no need to worry about deleting any data from your signal app.

Make sure that the data/files from your signal app that you'd like to transfer to your new device doesn't include any personal information (eg account login). If it contains any personal information such as your password it could give other people access to that information if they are able to use your Google Account to sign in. The safest way to prevent this is to not store passwords in any online accessible way.

You can use a simple tool like Keepass (free open source) to keep track of your passwords and other account information and sync them to your new device if you're concerned about someone else accessing your Google account from the app. After uninstalling the signal app, the connection info in your settings on the Google Play store should also be available to your new device if you signed in with a Google Account prior to the upgrade. If you don't have a Google Account, you'll need to use your device's email address and set up a password when you first set it up.

Why is my Signal QR code not working?

I've created a QR code that directs to a website.

In the instructions, it says that the website will be displayed on the first page of the website. When I scan the QR code, nothing happens. The website isn't displayed. What's wrong?

I don't think it is about the code but more about the fact that you have added your own website in the QR code. It should be a link or rather a reference to your website. You can test this by creating an e-mail address as a part of the link and send an email to it.

If you want to use your own website, you must add the HTTP scheme (which in this case is http://) to your URL. To get a working example, try this: It will generate a QR code that points to google.com.
