04-04-26 Why Your Phone Fails at Big Events, QR Code Scams to Avoid, and Tech Troubles in Space

Ever wonder why your phone becomes practically useless the moment you’re surrounded by thousands of people at a concert, festival, or ball game? Or why astronauts heading to the moon deal with the same Microsoft Outlook glitches you do at home? In this special live edition of Tech Talk — broadcast from Spring Fiesta at Lake Eola in Orlando — David Leavitt and Greg Rhodes dive into why your cell service tanks at crowded events, how NASA troubleshot a very relatable tech problem aboard the Artemis mission, why QR code scams are exploding, and some breaking news about Microsoft Publisher reaching end of life. Let’s get into it.

Why Your Phone Stops Working at Big Events

Picture this: you’re at a packed outdoor festival — maybe 100,000 people around you — and you try to upload that perfect selfie or FaceTime a friend. Nothing happens. You’ve got bars on your phone, so what gives?

The answer is network congestion. When tens of thousands of smartphones are all trying to use the same cell towers at the same time, the system gets overwhelmed. It’s like rush hour on the highway — the road is still there, but nobody’s moving.

Why “Full Bars” Can Still Mean No Internet

Here’s something most people don’t realize: your phone’s signal bars only tell you whether your device can connect to the network. They don’t tell you whether the network has enough capacity to actually move data back and forth. Connection is the first priority for the system. Transmitting your photos, messages, and web pages is the second priority — and when thousands of people are sharing that same tower, the second priority suffers.

5G Makes This Trickier Than You Think

With 5G, there are actually more towers than there were with older 3G networks, but each tower covers a smaller area and transmits with less power. Think of it like your home Wi-Fi: the farther you walk from your router, the weaker your connection gets. The same principle applies to 5G towers. As you move through a packed venue, your phone may hop between towers and lose usable speed along the way.

Quick tip: If your phone is clinging to a weak Wi-Fi signal (like from your car in the driveway), it might actually prevent you from using your cellular data. Turn off Wi-Fi when you leave home so your phone switches to the stronger cell connection.

Also worth knowing: budget carriers like Cricket and Boost Mobile use the same towers as AT&T, T-Mobile, and Verizon. So switching to a smaller carrier won’t save you from congestion at a big event — you’re all sharing the same infrastructure.

Space Tech Problems: Even NASA Deals with Outlook Glitches

NASA’s Artemis mission — the first crewed voyage toward the moon in over 50 years — experienced a tech issue that sounds almost too mundane for a moon-bound crew: Microsoft Outlook stopped working.

What Happened with Outlook on Artemis

Commander Weissman’s laptop had two Outlook accounts running at the same time — a personal account and the official NASA account. While Outlook is designed to handle multiple accounts, running two instances simultaneously caused a glitch that locked up the email client. This is exactly the kind of issue that the technicians at Refresh Computers see and fix on a regular basis.

Mission control in Houston remoted into the laptop — yes, from Earth — and resolved the configuration conflict, just like a tech support professional would do for you at home. It’s a great reminder that configuration issues don’t discriminate. They happen on the most advanced systems in the world, and they happen on your home PC, too.

The “Lunar Loo” Malfunction

In a lighter (but still important) story, the Artemis crew also experienced a toilet malfunction aboard the Orion capsule. A jammed fan — an electronic failure — prevented the system from properly collecting liquid waste. Fortunately, mission control was able to walk the crew through a fix in just a couple of hours. One of the astronauts joked that she could now add “master plumber” to her résumé. Even in space, electronics break, and practical troubleshooting saves the day.

Takeaway: Whether it’s a laptop on the Artemis spacecraft or a desktop in your home office, most tech problems come down to configuration errors or hardware hiccups — and they’re almost always fixable with the right help.

QR Code Scams Are Exploding — Here’s How to Protect Yourself

QR codes are everywhere now — restaurant menus, vendor booths, parking meters, event tickets. They’re incredibly convenient, but they’ve also become a favorite tool for scammers. One of the fastest-growing scams involves placing a fraudulent sticker over a legitimate QR code. You scan it thinking you’re paying for parking, but instead your payment and credit card details go straight to a criminal.

How the Sticker Scam Works

Scammers print thousands of QR code stickers and place them over real ones on parking meters, gas station signs, restaurant tables, and unattended payment kiosks. When you scan the fake code, you’re taken to a convincing clone website where you enter your payment information. The result: you pay the scammer instead of the actual business, and you may not even realize it until fraudulent charges start piling up.

Quick Habits That Reduce Your Risk

• Preview the URL first. When your phone camera reads a QR code, the destination URL appears on screen before you tap. Read it carefully. If it doesn’t match the business name or looks suspicious, don’t tap.
• Look for sticker outlines. Run your finger over the QR code. If it feels raised or you can see the edges of a sticker, don’t scan it.
• Be extra cautious at unattended locations. Parking meters, gas pumps, and standalone signs are prime targets because nobody is watching them.
• Never click unexpected links in texts. Your toll company, bank, and delivery service will not send you payment links via text message. Delete and report as spam.
• Enable credit card transaction alerts. Set up text notifications for every purchase so you’re alerted immediately if someone uses your card without your knowledge.
• Use tap-to-pay instead of inserting your card. Card skimmers hidden inside gas pump and ATM slots can steal your information. Tap-to-pay avoids that slot entirely.
• Monitor your accounts after using any QR code. Even at trusted locations, check your bank statements for unexpected or recurring charges.

Rule of thumb: If you didn’t expect the QR code, don’t scan it. If you did expect it, inspect it first.

Breaking News: Microsoft Publisher Support Ends October 1

Microsoft has announced that it will end support for Microsoft Publisher after October 1st of this year. If you or your business still uses Publisher for brochures, trifold pamphlets, posters, or flyers, now is the time to act.

What You Should Do Right Now

• Find your Publisher files. Search your computer for files ending in .PUB — that’s the Publisher file extension.
• Convert them to Word format. Microsoft recommends converting your .PUB files to .DOCX (Microsoft Word) format before the deadline.
• Consider alternatives. Microsoft Word and PowerPoint can both handle the layout tasks that Publisher was known for. There’s no need to buy special software.

If you still have an older DVD version of Microsoft Office from 2019 or 2021 that includes Publisher, you’ll technically still be able to open those files — but you won’t receive any security updates or support. For schools and small businesses that have relied on Publisher for years, this transition is worth tackling sooner rather than later.
