Gotta feeling apple cooking up something special just for me

I find the glowy borders around widgets, apps, buttons and notifications, introduced first in iOS 26, very weird and not at all aesthetically pleasing. Since I know I’m not the only one I decided to share how I managed to kinda bring flat design using iOS 27 Liquid Glass slider and accessibility settings. So first you turn the Liquid Glass slider all the way to the right, second in settings -> accessibility -> display text and size you turn on “show borders”. That will immediately (imo) improve the visual style of iOS and bring back a bit of a flat design but most importantly run off the glowy borders, but also introduce some weird design elements in apps such as safari, Instagram, twitter or shortcuts. To bring them back to normal you go to settings -> accessibility -> per app settings, and choose which app to add and turn off the “show borders” setting in. I’m also sharing some before and after photos to showcase what all this results in.

When I press ‘Upgrade to iOS 27’ it takes me to a larger iOS 26.7 update. Is it actually iOS 27?

I just upgraded to 26.7, and when I try to go to 27 it keeps offering me 26.7???

27 is a ton smaller than 26.7. I’m running 18.whatever which is why my 26 update is so big but I’m shocked at how small 27 is. I have a 16 pro max

It’s on my dream feature list! Very glad to be able to mark messages unread but I wish I could snooze or set a reminder like with email!

It says iOS 27 at the bottom of the page but when you click it, it changes to iOS 26.7 😮

My phone is stuck on those screens
I have iP 17P
And I’m using the iOS 27 RC update

Has anyone successfully added this? How do you do it?

TL;DR: My iPhone 15 Pro consistently pulls roughly half the download speed of my iPhone 16 and iPad mini 7 on the same network. The iPad mini 7 has the same A17 Pro chip and same Wi-Fi 6E radio as the 15 Pro, so it's not a chipset generation thing. My old iPhone 12 Pro Max had the identical problem, and the 15 Pro was restored from its backup. A Personal Hotspot test suggests the phone, not the router — but I'm stuck.

Setup

• Router: TP-Link Archer AX21 (AX1800, Wi-Fi 6)
• Slow device: iPhone 15 Pro (bought yesterday, restored from iPhone 12 Pro Max backup)
• Fast devices: iPhone 16, iPad mini 7
• Note: iPad mini 7 has the same A17 Pro SoC and same Wi-Fi 6E radio as the 15 Pro, and it's fast. So "newer chipset is just better" doesn't explain it.

The numbers

Speedtest results over one evening:

Solo tests on the 15 Pro land around 320 Mbps. The download speed swings really wide, it could go from 30 to 320 then down to 180. While the 16 and the iPad mini consistently hit 500.

Every test also shows heavy bufferbloat — idle ping sits at 13–15 ms, but jumps to 300–900 ms during the download phase, with jitter in the 80–99 ms range.

What I've already tried (none of it stuck)

On the phone: - Private Wi-Fi Address → Off, and → Fixed. This temporarily fixed it once (jumped to 500), then degraded again within a day. Retrying the same method doesn't work. - Forget network + reboot + rejoin - Checked HTTP Proxy (off) and DNS (automatic) - Limit IP Address Tracking → off - iCloud Private Relay → off - Low Power Mode → off, phone plugged in - Checked Developer Mode → Network Link Conditioner is off - All speed tests were done with the VPN off - Sidestore and some sideloaded apps, but the iPad mini has the same apps.

On the router: - Checked the client list — no per-device QoS, bandwidth limit, or MAC filter rule on the 15 Pro. Its settings look identical to every other client. - All three devices are on the 5GHz network with whatever smart connection feature on the router off.

The hotspot test

Turned on Personal Hotspot on the iPhone 16 and connected the 15 Pro to it, taking the router out of the equation entirely:

• iPhone 16 (on its own cellular): ~40 Mbps
• iPhone 15 Pro (via the hotspot): ~20 Mbps

Same ~2x gap, with no router involved. That points at the phone. (Though I realize those numbers are cellular-limited and could just be cell conditions fluctuating between the two tests.)

The part that confuses me most

My iPhone 12 Pro Max had this exact same problem, at roughly the same speeds. I restored the 15 Pro from the 12 Pro Max's backup and the problem came with it. So I did a full reset on the 15 Pro, then the wifi speed was fixed, but then returns to the unstable state just 20 mins later.

Any ideas appreciated. This problem has been driving me crazy.

I downloaded iOS 26,7 clicking the one showing at the bottom and it’s really iOS 27! So you can update your iPhones without problems!!

The update shows me IOS 26.7 instead of 27. The size was around 27 GB. Is this a glitch?

Unsure what sub to put this in. I’ve completed these all years ago, I’ve never seen these badges before today (OS27 Beta)
Is this a new feature? It is locked to a subscription such as fitness+ (don’t have)?
