Solved: How do I fix phone calls not waking lock screen on One UI 6

If you’ve recently updated to One UI 6 and noticed that incoming calls aren’t waking up your lock screen, you’re not alone. This particular bug seems to have slipped through the cracks in the latest OS update from the South Korean tech giant, bringing both exciting features and a handful of glitches.


The problem is more than just an inconvenience. Users find themselves manually unlocking their phones just to see who’s calling, and it’s not limited to regular phone calls – even third-party apps like WhatsApp are affected.

The good news? There’s a simple workaround to fix this issue. In this guide, we’ll walk you through the steps to get your lock screen responding to incoming calls smoothly on One UI 6. Let’s dive right in.


Let’s tackle the issue upfront – it’s not a bug; it’s part of the new One UI design. After updating, you need to grant apps permission to show full-screen notifications, even if they had it before. To do this, go to Settings > Apps > overflow icon > Special Access > Full-screen alerts. That’s it!


Give the suggested tweak a try, and you should see your lock screen waking up for calls on One UI 6. Any questions about these steps? Drop them in the comments, and we’ll provide a solution promptly.
