Are you using a Sony Xperia device?

We are currently experiencing sign-in issues on Sony Xperia devices. Until we have a proper solution for this problem in place, please try update the SoundCloud app to the latest version, and try signing in again.

There are two known workarounds for this issue:

• doing a full factory reset while not using an SD card
• logging into a different account (does not always work)

Once we have a proper fix for this problem in place, we will post an update on our status blog.
