If you use some app such as Network Survey (open source, Android), you can see that providers also lie about the type of connection. I'm on LTE now, but provider makes phone display 5G. And this is on non-provider phone, this is built in in the whatever communication they do with the phone, possibly works with every device.

Thank T-Mobile crying to the ITU-R to get 4G and 5G technologies renamed so they could peddle bullshit marketing.

Man, I love my HSPA+ “4G”!

A friend recently got a (carrier-supplied) phone and has been complaining about how it would often have no reception despite showing a good signal; taking mine to the same areas on the same carrier and doing a comparison, mine was indeed showing no bars on the signal indicator. The difference is, mine predates this stupidity, and I can also see the details in the MTK Engineer Mode app, which shows the actual signal s…

I highly recommend Network Cell Info Lite app for the network diag. It shows signal strength with all details for each of the SIM modules, shows on a map in real time where are the base station you are currently connected to, and other interesting statistics.

"Tests carried out by research group PolicyTracker, and shared with BBC's Morning Live, found that nearly 40% of the time a phone displays the 5G symbol, it is actually using a 4G connection"

> You know, I don't recall ever seeing 1 bar of signal strength on a smartphone. I do. I'm from Germany, land of perpetual EDGEing. Highest total GDP in the EU but can't build a mobile network for the life of it. Then again we somehow forgot how to run trains and build cars without cheating, so I guess it fits. Want to see a single bar? Come visit, our carriers aren't on the list with that inflate flag enabled. I gue…

I feel you. We have stellar coverage pretty much everywhere in NL. Heck, I was recently in a work video meeting in the car, not a single drop. The route included part of this: https://en.wikipedia.org/wiki/Afsluitdijk Yet, when we visit family in Germany, five minutes after crossing the border we are in a cellular dead zone.

Interesting to see you have a different experience. I'm not sure I would call it stellar. On the train route between Den Haag and Amsterdam, one of the busiest routes in the country presumably, reception is constantly dropping out. I'd love to be able to work on the train, but it's completely impossible if you need a network connection for anything.

Perhaps the route being so busy is the cause of the connectivity issues, but it's still baffling to me how bad it is, given that the amount of mobile devices trying to connect must be very predictable.

You know, I don't recall ever seeing 1 bar of signal strength on a smartphone. And once it's down to 2 bars, it barely works, if at all. Human brains: wow, what a bunch of suckers. Damn. By the way, is it legal to be deceptive in this way?

Android phones show 1 bar pretty reasonably and fair. To illustrate this, I have 1 bar on both my SIM modules right now, which translates to the -125 dBm signal on both. So the connection is up, but it is borderline low.

Wifi-calling to the rescue :)

Is there any reason to believe this mechanism is actually there to help carriers deceive users? To me this looks like it's intended to address some other issue, like perhaps "I have zero bars shown, what do you mean I'm still connected? That that clearly means I'm disconnected..." I feel like anything intended to lie to users would not be implemented in this manner.

I implemented the same behavior in a different Google product. I remember the PM working on this feature showing us their research on how iPhones rendered bars across different versions. They had different spectrum ranges, one for each of maybe the last 3 iPhone versions at the time. And overlayed were lines that indicated the "breakpoints" where iPhones would show more bars. And you could clearly see that on every r…

To be sure, is it possible that, on each subsequent iPhone release, the hardware got better at handling weak signals, and thus a mediocre signal for iPhone N was decent for iPhone N+2 and would give great throughput on iPhone N+4?

Possible sure, but wouldn't it be better marketing for the iphone to have better performance on lower bars? Phones are judged for their performance, but network providers for the number of bars they show on the screen.

Thats why I experienced 2 bars equals zero internet today?

I build apps at the moment, in addition to the phone's network indicators you really should provide your user with visible and live feedback to indicate whether the servers are reachable because there's so many things that can break down in between. Also programming your app for offline-first is good unless it's critically important the information is either live or absent. We allow offline access by using React Query and storing its caches in user storage.

With Three UK, I have not 1 bar but 5 bars!

Until about March this year, it was excellent and I used it as my home broadband. 60MB/s down, 20MB/s up on a good day. Much better than any ADSL I'm able to get.

Since March, from about 10:30am until 5pm some days, and late evening other days, there is no working data, and occasionally no working voice, despite the 5 bars.

It's working fine until then, and then it just stops completely, fading over the course of maybe 10 minutes. This happens all 7 days of the week.

The working theory is congestion at the base station. That's consistent with the occasional 6 minute ping times that I've measured, and more usual 20-30 second ping times, when anything gets through at all.

Still shows 5 bars. Three's coverage map says it's good here. Just can't use it.

I wonder if it’s more intuitive that way. Like what Apple does with stopwatch. https://lukashermann.dev/writing/why-the-iphone-timer-displa...

This is just rounding to nearest instead of down or up, not statically adding a whole interval (as the author realizes in an addendum).

My oven always rounds up. Until the last minute, when it immediately switches from 2 minutes to 59 seconds.
