Google has just released the fourth beta update for Android 15. This one doesn’t add much in terms of new features, but it does push the software to another key milestone in terms of platform stability. Developers can lock in all the crucial changes before the final public release.

This would be the second one, actually, as Android 15 reached the first platform stability stage with the arrival of the Android 15 Beta 3 update in June. “Developer APIs and all app-facing behaviors are now final for you to review and integrate into your apps, and apps targeting Android 15 can be made available in Google Play,” explains Google.

One of the biggest shifts in the latest beta update is the move away from PNG-based emoji font files to those based on the vector format. A crucial benefit of vectors is that they are scalable without losing visual quality, making them an ideal choice for responsive design across various screen sizes and resolutions.

The decision was made a couple of years ago with Android 13, but Google kept both in flux to give developers time to shift from PNG to SVG vector foundations. Now, Google is ready to make the jump, and as a result, some phones (read: Pixels) will exclusively rely on vector emojis.

Nothing screams design revolution better than crisp vector emojis, eh?

The update also tweaks app activity behavior, keeping apps active unless they are launched or the user interacts with them. With this update, Google is also releasing Private Space to the masses.

One of the most eagerly anticipated features of Android 15, Private Space lets you create a hidden space for apps behind a layer of passcode or biometric security. This is a perfect space to keep banking, communication, gallery, and social media apps hidden in plain sight from prying eyes.

There are a whole bunch of other features that are now ready for developers to integrate. Among them is a new exposure model for camera capture that lifts the quality of images captured in lowlight situations. Partial screen sharing is among my favorite additions.

The ability for an app to flag when it’s being recorded is also a solid addition. We have a detailed overview of Android 15 from its preview days and will soon bring an exhaustive review as the public release inches closer.

Apple’s new Upgrade program launches on Tuesday with major changes

Buying your next Apple device could soon look like leasing a car. Apple is launching its new Apple Upgrade program on Tuesday, July 28, replacing new enrollments in the long-running iPhone Upgrade Program with a lease-based option that covers iPhones, iPads, Macs, and Apple Watches.

Backed by Klarna, the program is designed to lower the upfront cost of Apple's premium devices, but it is also raising questions about whether you'll actually own what you're paying for.

Setting up your dorm desk? These are the phone stands I’d actually spend my money on
From a $2 folding stand to a three-in-one Apple charging dock, these are the phone stands worth setting up this semester.
Analog Clock, Clock, Electronics

A phone stand is one of the smallest purchases on any back-to-school list, but it's also one of the easiest to get wrong, especially since there are dozens of options available on Amazon. A good phone stand is one that does its job well and, more importantly, doesn't put much of a dent in your budget.

This is one of those product categories where you don’t need to spend big, unless a MagSafe dock or a multi-device charging stand is genuinely useful for your desk or dorm setup. That is why this list begins with the most affordable options and works its way up to the more expensive ones. From a two-pack that costs about as much as a coffee to a three-in-one Apple charging station, I picked eight of Amazon's best-reviewed phone stands worth considering this back-to-school season.

I picked four wireless chargers so you can stop making your iPhone, AirPods, and Apple Watch fight over one dorm outlet
The best back-to-school wireless chargers for dorm desks, study spaces, and travel
Computer, Electronics, Laptop

A dorm-room desk can disappear surprisingly quickly beneath a laptop charger, phone cable, Apple Watch puck, and the growing collection of adapters required to power them all. Add textbooks and other academic materials, and finding enough room to study becomes the first assignment of the semester.

A wireless charging stand can consolidate several of those cables into one station. It also gives your phone a dedicated place to sit, which helps when you are checking the time or watching a lecture. Every charger here still needs one connection to the wall. So finding a peripheral that works with all of your gadgets isn't just convenient, it's smart. I picked four models ranging from an inexpensive two-device stand to a fast 25W wireless charger capable of powering an entire Apple setup.
