One UI 7 on the S23U: Fix the notification pull down

I upgraded my Samsung Galaxy S23Ultra a few days ago to One UI 7, or Android 15 and it has mostly been a good upgrade, but it hasn’t been perfect.

The first and most annoying, change was to the notifications when you pull down on the screen. There’s no sign of the quick settings anywhere. It turns out you have to pull down from the top right. This comment on Reddit explains how to fix it by:

  • Tapping the pencil icon.
  • Going into panel settings.
  • Change it from Separate to Together.

The other annoyance is the three rows at the end of the quick settings panel.

  • Play music / Media output
  • Nearby devices / SmartThings
  • Smart View / Modes

You can sort the order they appear in, but you can’t remove them. I never use them. Annoying.

The camera is fine. The UI has been changed a little. I haven’t noticed any change in picture quality yet.

I’m glad the apps drawer in the default launcher can now be scrolled vertically again. That is a feature of almost all third-party launchers, and “Home Up” used to enable it, but One UI 6 removed it years ago.

I had to delete my phone from my car’s Android Auto interface to get it to connect reliably again. I should say “reliably” with quotes because Škoda cars seem to have problems with this phone (or at least the 2020 Kamiq does), and I had to buy an Android Auto dongle to make it work. Thankfully, the new version of Android seems to work ok with the dongle.

The “do not disturb” Meeting widget is now two spaces big for no reason,

I like the UI refresh, the rounded corners are nice.

Primer (Oscilloscope Music)

Here’s a cracking demo by DJ_Level_3 and Marv1994 done on an Oscilloscope, with the music creating the visuals. The music is great too, but of course, it’s not really responsible for the visuals, there are high-frequency sounds doing that, which we can’t hear. Utterly amazing stuff.

The demo got 1ST PLACE in Wild, and 1ST PLACE in Crowd Favorite at the recent demo party, Revision 2025.

Thanks Hackaday for featuring it.

This will be upsetting if you eat meat

This video will be even more upsetting if you don’t eat meat because there’s nothing in this video that you don’t know already.

Thanks to my wife, I don’t eat meat very-often these days. She hasn’t eaten it in years, and her influence is showing in our cooking and meal prep.

Try eating meat less often. Have a vegetarian or vegan meal once a week at first. When you realise you’re not missing out, have meat less often! You don’t need to give it up entirely. Unless you want to.

What struck me most about the Kurzgesagt video was how it laid bare the reality of animal suffering in the meat industry. They didn’t sugarcoat it. Most animals we consume live in truly horrible conditions, not for better meat quality but simply for cheaper prices. Meat is cheaper now than it was for our parents. The video breaks down the situation by animal type, chickens, pigs, and cows, and shows the specific challenges each faces in industrial farming.

The most eye-opening part? Often, we could avoid most of this suffering by paying just a bit more – sometimes only pennies per meal. That’s a small price for significantly reducing animal torture while still enjoying meat occasionally.

Remember, this isn’t about perfection or judgment. Every meat-free meal makes a difference. Whether you’re doing it for ethical reasons, environmental concerns, or health benefits, reducing meat consumption is a personal journey.

Have you tried reducing your meat intake? What vegetarian dishes have surprised you with their deliciousness? I’d love to hear your experiences in the comments below. I cooked a delicious sweet corn butter masala today that was mildly spicy, but rich in flavour and very filling.

Malaysia, no 1 for recycling

it’s fitting that I was listening to the segment at around minute 18:00 of this podcast about recycling when I was putting the rubbish bins out.

Most of the recycled material in Europe ends up in Malaysia, apparently. And it sure isn’t completely recycled.

An EPA report stated that, “Plastics present a serious challenge. Only 28 percent of plastic packaging waste was recycled in 2021, a long way off the 2025 EU target of 50 percent. The majority of Ireland’s plastic packaging waste is being incinerated.”

If a portion of that 28% of plastics is being sent abroad, then our recycling rate must be even worse.

Dorothy Vs Hitler

I’d never heard of Dorothy Thompson, but I’m glad I’m listening to this podcast about her. She’s the, “woman who warned the world”.

In 1939, Time Magazine called Dorothy Thompson a woman who “thinks, talks and sleeps world problems — and scares men half to death.” They weren’t wrong.

Why don’t you know about her? She saw what happened to Palestinians after WWII. She spoke out about it and faced immediate pushback from Zionist organizations and the newspapers that published her opinion pieces.

We need more Dorothys now.

Don’t blindly follow AI instructions

I’m trying to share a Time Machine volume with another Macbook on my home network but it’s not working. I’ve tried Google, and read through a few Reddit threads, but I haven’t been able to get it to connect. So, I asked Perplexity for help.

It helpfully listed a number of things I could try, but then I saw tip number seven.

Clean up stale mount points: Sometimes, stale mount points can cause issues. You can try to remove them by running the following command in Terminal:

sudo rm -rf /Volumes/*

Then restart your Mac and attempt to mount the shares again.

When you look up advice online, don’t copy and paste any instructions into your computer without knowing what it does.

What does sudo rm -rf /Volumes/* do? It recursively deletes everything in your /Volumes folder. A little bit destructive.

I told it that was a dangerous command, and it went on to talk about using the mount command to list every mounted volume and then unmounting them with umount.

Me: Tip 7 is not helpful. That would delete all the data in /Volumes/

Perplexity: You’re absolutely right, and I sincerely apologize for that dangerous suggestion. Thank you for pointing out this critical error. You are correct that deleting the contents of /Volumes/ would be extremely harmful and could result in data loss. Let me provide a corrected and safer approach.

PS. Otherwise, Perplexity is great. I’ve had great success with it and other AI tools when developing software.

Press F to pay respect

I only recently found out why people sometimes comment “F” on Reddit threads. It comes from Call of Duty: Advanced Warfare (2014).

At one point, you walk up to a casket at a funeral and have to press F to pay respects to the fallen soldier.

As others on that Reddit thread said, I thought it had something to do with following a thread to get notifications. Just to prove how out of touch I am, it even has a Wikipedia page where the viral meme is described as iconic, but the authors of that page describe it well:

Press F to pay respects” is an Internet meme that originated from Call of Duty: Advanced Warfare, a 2014 first-person shooter in Activision’s Call of Duty franchise. It originated as a set of instructions conveyed during an in-game quick time event at a funeral service. Widely mocked by critics and players due to its forced element of interactivity that was not perceived to be tastefully executed, the phrase would later become a notable Internet meme in its own right. It is sometimes used by Internet commenters to convey solidarity and sympathy, either sarcastic or sincere, in response to unfortunate events.

I never thought I’d be tagging a post with “Call of Duty” again, but here we are in 2025!
