We got our first glimpse of the imminent OnePlus 13T(Image credit: OnePlus)The next OnePlus phone launch is almost upon us, with the OnePlus 13T officially arriving on April 24. We can take a good, long look at the handset before then, though, because OnePlus has released a short video showing the phone in three different colors.We can see a flat back, curvy corners, and a new button that's replacing the standard OnePlus alert slider on this handset.

Samsung’s One UI 7 rollout hit some serious snagsThe Samsung Galaxy S24 (Image credit: Future | Roland Moore-Colyer)Getting One UI 7 out to the masses has proved to be quite the challenge for Samsung, and just when we thought owners of Galaxy S24, Galaxy Z Fold 6, and Galaxy Z Flip 7 phones would be getting the update, the rollout was put on pause amid reports of a serious bug.It's likely to mean that owners of older phones, including the Samsung Galaxy S23, are going to have to wait even longer to get their One UI 7 upgrade. With Android 16 (and therefore One UI 8) just around the corner, it's not a good look if you're Samsung.

The music died in Spotify’s biggest outage in yearsIt's not been the best of weeks for Spotify (Image credit: Shutterstock / Diego Thomazini)We found ourselves scrambling for our CD decks and radio dials on Wednesday – or maybe just YouTube – as Spotify suffered one of the most serious outages in history. Reports of unresponsive apps came flooding in from across the world for most of the day.

We still don't know exactly what happened to trigger such a major problem on Spotify's servers. Perhaps the music streaming service is too embarrassed to tell us, but the company did specifically say that it wasn't a cyberattack causing the extensive issues.Read more: Spotify was down – here's everything we know about its huge outage4.
