When a green bubble appears in the top-left corner of your screen — right behind your time or clock — this means you’re on a call or your iPhone is being used as a personal hot spot. If you’re not using it and you see the green bubble, another device may be connected to your hot spot and potentially using your data without your knowledge.
How to prevent unauthorized use
To prevent unauthorized access to your personal hot spot, ensure you have a strong password set up.
- Go to Settings
- Click Personal hot spot
- Tap on Wi-Fi Password to create a secure password. It’s also a good practice to regularly check and change this password.
Identifying who is using your hot spot
You can see how many devices are connected to your hot spot by opening the Control Center. For iPhones with Face ID, swipe down from the top-right corner; for iPhones with a home button, swipe up from the bottom. Press and hold the wireless section to see the number of connected devices.
Kicking off unauthorized users who are using your hot spot
If you find an unknown device connected to your hot spot, you can disconnect it by changing the hot spot password or turning off the personal hot spot feature.
- Go to Settings
- Click Personal hot spot
- Toggle off Allow Others to Join.
- Then, turn it back on and share the new password only with trusted devices. Also, consider using a password manager to generate and store complex passwords.
Remember, monitoring your hot spot connections regularly is important to ensure no unauthorized usage, which can lead to data loss and potential security risks.

When a purple bubble appears in the top-left corner of your screen — right behind your time or clock — this means your iPhone is using SharePlay, which can be used to share content such as games across iPhones.
Navigating apps, calls and hot spots with a tap
Now that you know what these different colors mean, you can be more aware if your iPhone is doing something you don’t want it to do.
Curious to see exactly what app or iPhone function is being used with these different color bubbles? If you tap on the clock when there is a color behind it, it will take you to the app or the control settings for the function that is being utilized.
For example, if you tap the clock when the bubble is green, and you are on a call, it will return you to the main window where you can see who you are speaking with.
If your iPhone is being used as a personal hot spot, tapping the green bubble will send you to the personal hot spot section of settings, where you can see who is using it and turn it off if you never intended it to be used as a hot spot in the first place.

This is where knowing what these color bubbles are comes in handy. On one hand, you can use them to maneuver apps or settings on your iPhone easily. From the security and privacy perspective, you can now be alerted when any apps or other people are utilizing information or functions from your iPhone you don’t want them to.
Uncover and block unwanted access to your iPhone’s camera and microphone
If you see that your iPhone’s microphone and/or camera are in use even though you don’t have an app opened, it likely means that an app has permission to use those features on your phone even when it isn’t being used or your phone may have been hacked. In our article, “Is your device spying on you?” you will find step-by-step instructions to see which apps have permission to access your microphone or camera and how to turn those features off.
If you’ve gone through your permission settings and your microphone and camera are being accessed without your consent, there is a chance that some malicious spyware may be using your device to spy. If you’re not sure your phone has been compromised, you can check for these additional signs outlined in our article, “How to tell if your phone has been hacked.”
To avoid this, consider adding good antivirus software to your phone to prevent malware. Also, the best way to protect yourself from clicking malicious links that install malware that may get access to your private information is to have antivirus protection installed on all your devices. This can also alert you of any phishing emails or ransomware scams. Get my picks for the best 2024 antivirus protection winners for your Windows, Mac, Android & iOS devices.

Kurt’s key takeaways
The colorful indicators on your iPhone serve as a visual guide to what’s happening behind the scenes. Whether it’s the blue bubble alerting you to location services or screen mirroring, the green bubble indicating an active call or hot spot usage, the red bubble warning of recording in progress or the purple bubble signifying SharePlay activity, each color plays a crucial role in enhancing your awareness and control over your device’s functions.
By understanding what these colors represent, you can take proactive steps to protect your privacy, manage your connections and optimize your iPhone experience. This subtle yet powerful feature underscores the importance of being informed and vigilant about the digital footprints we leave. So, the next time you notice a colored bubble behind the clock, remember it’s more than just a design choice — it’s a gateway to understanding and managing your iPhone’s diverse capabilities.

Microsoft closed out Summer Game Fest with a bang. The company’s annual June showcase was packed with crowd-pleasers: Halo, Gears of War, Fable, a translucent Xbox, and even some pleasant surprises like new Persona and Crazy Taxi games. It was the kind of event that harkened back to the boisterous days of E3, when the industry was in a healthier place and game reveals were cultural events.
Just three days after the showcase, new Xbox CEO Asha Sharma warned of a “reset” at Microsoft’s gaming division, which would require “making hard choices.” The weeks that followed were filled with reports of impending layoffs, studio closures, and game cancellations. Ninja Theory is reportedly one of the studios on the chopping block, despite having just revealed a new game at SGF. If all this comes to pass, Xbox will be a shell of its former self.
After muscling its way into the console space nearly 25 years ago, Microsoft’s gaming division is at its lowest point ever. And the fallout from some disastrous decisions is going to get very ugly in the coming weeks and months.
It wasn’t always this way. With the arrival of the original Xbox in 2001, Microsoft seemed poised to be a viable contender in the space, with all of its resources helping it play catch-up with the likes of Sony and Nintendo. Major exclusives like Halo and a prescient foray into online play through Xbox Live helped to solidify this position for a time. But Microsoft flubbed the launch of the Xbox One in 2013 with an ill-fated push into non-gaming features like TV, and the brand has never really recovered. With the oft-confusing Xbox Series X / S generation, the company only fell further behind.
There are many reasons for this, but arguably the most damning was Microsoft’s extremely expensive push into subscription services. On paper it made some sense: Streaming services like Netflix were upending the film and TV landscape, so maybe the same could happen for gaming. Microsoft made some absolutely gigantic bets on this unproven future, spending billions of dollars to acquire studios and publishers in an attempt to build out a large library of content for Game Pass that would lure subscribers.
And while Game Pass proved popular initially, it ultimately plateaued, which meant that Microsoft spent all of that money on a business that didn’t grow anywhere near as large as it expected. (The service currently has around 30 million subscribers, while Microsoft had hoped to hit 100 million by 2030.) This misguided play also coincided with the “This is an Xbox” marketing campaign, which suggested that Xbox wasn’t a single console but rather a suite of Game Pass-capable devices, leading to even more confusion around the brand.
Just how bad are things? As Sharma and Xbox’s chief content officer Matt Booty wrote in the “reset” memo, “Excluding Activision Blizzard King, over the past five years, we have spent over $20 billion on ongoing investments in our content, platform, and hardware subsidy, but our annual revenue has declined nearly half a billion during that time. Going forward, this cannot continue.” The Activision deal, meanwhile, cost $68.7 billion. The company spent all of that money just to make it even less clear what an Xbox is.
This past February, there was a major shake-up at the Xbox division. Former boss Phil Spencer, who oversaw the brand through the Game Pass push and its many costly acquisitions, retired, while former president and COO Sarah Bond left the company. Despite some uncertainty around her lack of experience in the world of gaming — her prior role at Microsoft was head of the CoreAI division — Sharma’s early days provided some cause for optimism. She appeared willing to listen to fans on things like backward compatibility and exclusives, scrapped the unpopular Microsoft Gaming branding in favor of just Xbox, and moved the brand away from controversial AI features. She also made some strange and superficial changes, like restyling Xbox as XBOX.
But it’s clear the issues at Xbox run much deeper than a simple name change can fix. Sharma inherited a business that spent colossal amounts of money and had little to show for it, and now the bill is coming due. What makes this especially tragic is the sheer pedigree of the game studios that are being impacted. My colleague Tom Warren reported that Microsoft was mulling over closing at least five studios, which includes the likes of Arkane — best known for the wildly influential Dishonored series — and Double Fine Productions, a beloved team behind cult hits like Psychonauts, and more recently Keeper and Kiln. That’s multiple teams filled with talented individuals responsible for some of the most notable games ever made. Now they’re being discarded because of poor decisions they had no part in.
But even amid this apocalyptic landscape, Xbox’s issues feel particularly existential. Its hardware and subscription businesses are both faltering, and now it’s decimating its game development teams as well. Tom reported that the impending layoffs are expected to start next week, and it’s not clear yet just how widespread they will be. Part of the uncertainty is that we don’t know exactly what will happen to these studios; some may be hit with layoffs, some may be closed entirely, and some may be spun off as independent entities.
Whatever happens, though, Xbox will look drastically different once it’s all over. And given the dire state of console gaming, these might not even be the last changes for Microsoft’s gaming division.
- Sharma has done a lot of work to clean up the messaging around Xbox, but plenty of confusion remains, particularly when it comes to the company’s console exclusivity strategy.
- At the same time the Xbox is struggling, a new player is entering the space, as Valve launches the console-like Steam Machine.
- As always, Nintendo largely operates in its own parallel universe that has allowed it to largely weather the current storm.
- Bloomberg’s Jason Schreier has done some excellent reporting on the turmoil at Xbox, and has also helpfully condensed everything into a video on his YouTube channel.
- Matthew Ball is Xbox’s new strategy officer, and in an interview with The Game Business he explained how the brand is thinking about the next console, currently codenamed “Project Helix.”
- Speaking of execs, Booty talked to Game Informer following the SGF showcase to try and explain Xbox’s ever-changing strategy around exclusives, saying that “We want there to be a reason to believe and a reason to buy Xbox.”

Pudu Robotics has announced what it calls the first “full-scenario robot-serviced hotel.” The project will use robots across the entire guest experience, from reception and room service to cleaning, food preparation and guest support.
The hotel is set to open in 2027, with trial rooms and robot-powered services expected to begin in late 2026. Early guests will be able to try robot check-in and autonomous in-room delivery before the full launch.

COULD THE NEXT CHINESE THREAT WALK INTO YOUR KITCHEN ON TWO BATTERY-POWERED LEGS?
Pudu Robotics says its robot-run hotel will use AI-powered machines across check-in, room service, cleaning and guest support. (Pudu Robotics)
Where the robot-run hotel will be located
The hotel will sit on West Artificial Island, a man-made island tied to the Shenzhen-Zhongshan Link in Guangdong Province. That cross-sea bridge and tunnel project is one of the Pearl River Delta’s biggest transportation projects.
The location feels fitting. Shenzhen already has a reputation as one of China’s major technology hubs. Room-service delivery robots are already common in hotels across many large Chinese cities.
However, this project goes much further. Instead of adding a few robots to assist hotel staff, Pudu wants to create a connected robot service system that can handle the entire guest experience.
What robots will do inside the hotel
The planned hotel will include 44 high-end rooms, a restaurant, a gym and other guest spaces. Robots will take on roles across the property, including reception, room service, cleaning, food preparation and guest support.
That means you could check in with a robot, have luggage delivered by a robot and order drinks from your phone without calling the front desk. Then, cleaning robots would handle waste detection and room upkeep using AI.
Pudu says its robots will work from one shared intelligence framework. In other words, different machines will handle different jobs while staying connected through the same software system.
The robot staff behind the scenes
Pudu’s FlashBot will run an intelligent vending system, allowing guests to order drink deliveries by smartphone. The PUDU T300 will move luggage from the lobby to rooms.
Meanwhile, the PUDU CC1 Pro and PUDU MT1 cleaning robots will handle cleaning tasks using AI waste-detection technology.
At the Shenzhen launch event, BellaBot Pro served coffee while KettyBot Pro delivered refreshments and snacks. That kind of robotic service may still surprise many travelers. In Shenzhen, though, it already fits into a broader tech culture where robot baristas and drone food delivery are becoming more visible.

How AI will run the hotel experience
The hotel will rely on PuduFM 1.0, the company’s embodied intelligence foundation model. It will also use PuduAgent to manage intelligent operations across the hotel.
“This partnership represents an important step toward large-scale deployment of embodied intelligence in premium hospitality environments,” said Cong Guo, co-founder and CTO of Pudu Robotics.
He also said the project gives the company a chance to explore new service models where AI and robotics work together to deliver connected service experiences.
That may sound ambitious, yet the rollout will be gradual. The first public trial is expected in late 2026. A broader hotel opening is planned for 2027.
Why China is moving fast with robot hospitality
China has already embraced service robots in hotels, restaurants, airports and public spaces. The robot-run hotel takes that trend into a more advanced phase.
Shenzhen Culture & Tourism Industry Development will work with Pudu Robotics to turn West Artificial Island into a robotics and technology destination. The hotel is only one part of that larger plan.
Over the next four years, the island is expected to add more robotics across tourism and hospitality. That could turn the area into a testing ground for how travelers react when robots handle nearly every service touchpoint.

What this means for you
If this hotel works well, it could change what you expect from travel in the future. Faster check-in, automated deliveries and round-the-clock service may sound convenient, especially when you arrive late or need something quickly.
However, there is another side to this. A robot-run hotel also raises questions about jobs, privacy, safety and what kind of hospitality guests actually want.
Some travelers may love the speed and efficiency. Others may miss the warmth of a person who can read the room, handle a strange request or help when something goes wrong.
That is where this project becomes important. It may show whether people are ready for hotels where AI handles the stay from start to finish.

Kurt’s key takeaways
China’s first robot-run hotel feels like a major test of how far hospitality automation can go. We have already seen delivery robots roll through hotel hallways. Yet this project puts robots at the center of the entire stay. The convenience could be impressive. You could check in, order drinks, receive luggage and get room support without waiting on a busy front desk. For travelers who value speed, that may feel like a win. Still, hospitality has always been about more than efficiency. A great hotel stay often comes from small human moments. A kind greeting, a helpful suggestion or a quick fix when something goes sideways can make a trip feel easier.
If a robot-run hotel can give you faster service, would you miss the human touch or happily skip the front desk altogether? Let us know by writing to us at CyberGuy.com.

The Swift Observatory was launched in 2004, but recent solar storms have pushed its orbit lower, and it’s in danger of burning up in Earth’s atmosphere as soon as this year. To try and stave off its demise, NASA has enlisted Katalyst Space Technologies. The company’s Link spacecraft launched Friday with the goal of intercepting Swift, which has no propulsion system, and boosting its orbit back to its original position. Right now, Swift is circling at an altitude of 224 miles, and Link is aiming to raise that by about 150 miles.
Using a three-armed spacecraft to lift a satellite 150 miles higher into orbit is challenging enough, but the speed with which Katalyst pulled the mission together makes it even more impressive. NASA required the company to rush the job because Swift would be too low to save by October. $30 million and nine months later, help is on the way for the $500 million Swift.
