Nokia in 2025: 2720 Flip, Lumia 635, Clear Phone, Blood Pressure Monitor Symbols, and Multimeter Advice

Every few weeks, someone asks me what Nokia product they should buy. My answer usually starts with another question: What problem are you actually trying to solve? There isn't one right Nokia product. There's a basic phone for people who should not be carrying a smartphone, an old Lumia for people who want a piece of 2014 back, a health monitor brand that mostly isn't Nokia anymore, and a multimeter that has nothing to do with Nokia at all.

I'm an office administrator for a 60-person company. I manage all IT and office supply ordering, roughly $250,000 annually across 12 vendors. I report to operations and finance. I process 60-80 orders a year, and most of them are small, so I care less about specs and more about whether a product creates follow-up work.

This guide is organized as a decision tree. Pick your scenario, then read the relevant section.

The Quick Decision Tree

Before you buy anything Nokia-related, put yourself in one of these buckets:

• A. You need a durable, distraction-free phone for an employee who mainly calls and texts.
• B. You want a Nokia Lumia 635 for nostalgia or legacy testing.
• C. You keep seeing videos about a 'clear phone' and wondering if it's real.
• D. You're checking health data or testing chargers and cables.

The advice for each bucket is different. That's the point.

Scenario A: Nokia 2720 Flip Reviews Are Right, but Only for the Right User

The Nokia 2720 Flip reviews I read before buying were accurate. It's slow by smartphone standards, the KaiOS app store is limited, and the screen is small. Also, the battery lasts a lot longer than the smartphones it replaces. For someone who works in a warehouse, drives a delivery route, or keeps dropping devices, that tradeoff is worth it.

I bought four of these for our logistics team in 2024. The decision happened under time pressure: one driver's phone died in the morning, and I had two hours to find a replacement before the afternoon route. Normally I would compare three options and read more reviews, but a local store had the 2720 Flip in stock. I went with it because I knew people would only use it for calls and WhatsApp. According to HMD Global, the 2720 Flip runs KaiOS and supports 4G LTE, which is exactly why I chose it.

Here's something vendors won't tell you: a 'Nokia' phone today is made under license by HMD Global. That doesn't make it bad, but it means I check for software updates instead of trusting the logo. For the 2720 Flip, the security patch situation matters less because I don't ask users to log into banking on it.

The upside of the 2720 Flip was lower replacement cost and fewer broken screens. The risk was that a user would complain about missing apps. I kept asking myself: is saving $300 per device worth the complaints? In our case, yes, because the people who needed it did not want apps anyway.

The best phone for a worker is the one that doesn't create a support ticket.

Scenario B: Nokia Lumia 635 Is a Collectible, Not a Daily Driver

I often get requests for a 'nokia lumia635' because people remember the Lumia line fondly. I do too. The design, the tile interface, the camera feel, all of it had character. But the Windows Phone ecosystem is gone, and in 2025 a Lumia 635 is a collectible or an offline test device, not a phone I would hand to someone who needs to reach customers.

What I mean is, you can buy a Lumia 635 for around $30 to $60 on resale sites, and it will turn on, take photos, and maybe run a few legacy apps. But it doesn't support modern versions of important apps, and some 4G bands are missing depending on the model. If you want to recapture 2014, fine. If you want a reliable backup phone, spend a little more on the 2720 Flip.

I had to weigh this myself when a seller listed a Lumia 635 for $35 as a test device. The upside was saving maybe $60 versus a budget Android phone. The risk was battery degradation, no updates, and a user who would not understand why the apps didn't work. I passed. In hindsight, that was the right call because the follow-up questions would have cost more than the device.

Scenario C: The Clear Phone Is Probably Not What You Think

The phrase 'clear phone' gets searched a lot. I think most people picture a fully transparent smartphone that you can hold up and see through. As far as I can tell, that product does not exist in Nokia's current lineup. Honestly, I'm not sure why clear phone videos resurface every year. My best guess is they are concept renders, repackaged clips of a transparent-themed phone, or simple clickbait.

What you can buy is a clear case for a normal phone. That gives you the look without the fantasy price tag. If you see an order page for a 'Nokia clear phone,' I would be very careful. A product that isn't on Nokia's official website is either a design concept, a knockoff, or a scam.

One more thing: in the phone industry, 'clear' usually means the phone has transparent elements, not that the whole phone is transparent. That's why products like the Nothing Phone get folded into clear phone discussions even though they are not Nokia. It's a genuinely different design language, but it's not the same as a clear slab.

If you want a clear phone, buy a clear case. If you want a phone, buy a phone.

Scenario D: Blood Pressure Monitor Symbols and the Nokia Health Question

Let's start with a brand reality: Nokia owned the Withings health business for a while, then sold it back in 2018. So if you're looking at a Nokia-branded blood pressure monitor, it's probably old stock or a Withings device with Nokia branding. The hardware can still work, but support often lives in the Withings Health Mate app, not on Nokia's consumer site.

If you're searching for 'blood pressure monitor symbols,' here's the quick version. The symbols are not perfectly standardized across every model, but the common ones I've seen are:

• A heart icon: pulse rate, usually beats per minute.
• A heart with a jagged line or ECG trace: irregular heartbeat detected during that reading.
• A cuff icon: cuff is inflated or connected.
• A battery icon: low battery or charging status.

Take this with a grain of salt: I'm not a doctor, and I've never fully understood why every brand insists on different icons. According to the Nokia Health and Withings user manuals from that era, those symbols were described as pulse, irregular heartbeat, and error states. If an irregular heartbeat symbol appears more than once, that is worth discussing with a clinician, not just resetting the monitor.

The Best Multimeter for Home Use Is a Tool, Not a Nokia Product

Now for the keyword that seems unrelated to Nokia but isn't: best multimeter for home use. I buy a lot of Nokia chargers, cables, and small adapters. When one stops working, the fastest way to tell whether it's the cable, the charger, or the device is to test it with a multimeter.

For home use, the best multimeter is usually a basic auto-ranging digital model with a continuity beep and a CAT II rating. You don't need a Fluke for this. You don't need a clamp meter unless you're measuring AC current. In my opinion, spending more than $60 for general troubleshooting is overkill.

I keep a $40 Klein Tools multimeter in the supply closet. It sounds strange, but it saved our accounting team about six hours in 2024 because we stopped reordering good chargers that were actually connected to bad cables. What I mean is, the cheapest option isn't just the purchase price; it's the total cost of not knowing whether the device you're about to replace is actually broken.

According to IEC 61010, the category rating on a multimeter tells you where it's safe to use. CAT II is enough for plug-connected electronics; anything inside a breaker panel is a job for an electrician. I'm not one.

How to Decide Which Scenario You're In

When I took over purchasing in 2020, I made some decisions based on sticker price. Within a year, I learned that a device that creates support tickets isn't cheap. In our 2024 vendor consolidation project, I cut the supplier list from 18 to 12 and standardized the phones we buy. That cut admin time, because I stopped re-buying the same thing every time someone complained.

If you're still unsure, use these questions:

• Does the user need to install random apps? If no, the 2720 Flip is the better buy.
• Is the phone a daily driver? If yes, do not buy a Lumia 635.
• Are you chasing a transparent design? Buy a clear case, not a mystery phone.
• Are you buying for health monitoring? Check the app support before you check the brand.
• Are you testing power supplies? A cheap multimeter is a legitimate business expense.

My main bias, if I have one, is efficiency. A purchase that reduces support tickets, returns, and reorders is worth more than a purchase with better marketing. For my office, the order is: support, durability, price, features. In that order.
