@dobey No apt isn't. But the Playstore is evidently a malware distribution channel, and UT's only real method to install non-core software is the open-store, which follows (as you say) the same methodology as the iOS appstore (or the Playstore). It is IMHO only a question of time before we see malware in the open-store as well and no amount of app-confinement it going to stop a dedicated malware author.

@luke AFAIK you need to get the .apk and then install it via adb.

The developer of P2 is willing to add Ubports push notification support for XMPP clients, but it would need to be implemented by someone with Java knowledge. According to him it should be really easy though.

On an unrelated note, this might also be a portable qt native xmpp client: https://github.com/ksiazkowicz/lightbulb

It's the only battery I have, as the original one before was completly borked. But yeah, might be a hardware issue.
