Odd mapping omission in Specialized app [SOLVED]

[mschwett]

Interesting thought. Wouldn't have guessed poor coverage where the map trace ended. Wide open area with lots of homes and businesses nearby.

Besides, I record all rides and ride near that spot often. Never a problem before yesterday.

Haven't yet ruled out a chance encounter with a passing space-time discontinuity or rift in the subspace tachyon field. Those were the usual suspects when weird stuff happened on Star Trek.

idk if android is similar to iPhone but i bet it is, and the location services are provided by the OS using best-available information, including maps, wifi proximity, cell pings, and (mostly) GPS. you can definitely get good location without cell service and i'd be very surprised if android didn't do that. it would be a big problem.

my bet is a specialized app glitch in which whatever protocol it uses to collect and record the location data from the OS failed, but the unrelated protocol by which it gathers ride data over bluetooth from the bike did not fail. these are two different subsystems and i bet they can fail or succeed independently

Thanks! Fits the observations. I've now done all the things Samsung said to do to keep the S25 from dropping its GPS link. We'll see if it happens again.

@mschwett is right. Phones (Android/iPhone) use network assisted A-GPS, which improves the location service accuracy in urban areas. While bike GPS computers have to rely on the satellites only. For this reason, newer Garmin or Wahoo computers sport Multi-Band GPS, which intercepts two different radio signals from the same satellite for increased accuracy.

A-GPS has been as perfect as I could rely on the car satnav using my Android phones for a dozen of years. Now you cannot trust anything (except for the inertial navigation or dead reckoning, hehe). Again, the issue you Jeremy reported must have been caused by some glitch between the Specialized App and the phone location services.

On Sunday, we were riding through the Poligon. As it is a former military range, it is very easy to get lost there. Our Garmins and Wahoos worked perfectly, still we could make some navigational mistakes!

Mystery solved!
Somehow, GPS location got disabled on my phone — apparently at the ride stop where the route trace vanished below. No idea how that could have happened, as I recall messing only with the phone camera at the time.

Rode once more before fixing the problem and got this recording from the Specialized app:

This time, no map at all, and no elevation data recorded.

Well, one idea as to how GPS got turned off: The phone's touch screen is way too sensitive. And if put in a pocket for a while without locking the screen, you can easily find the phone many levels deep into a menu or website you never selected. Sometimes, a settings menu.

Turned GPS location back on, and the next ride recorded perfectly:

Thanks for everyone's help!

I guess yet another reason to run right out and get that flagship Samsung.... but if it wasn't your nipple that turned off the GPS, I'd look into the handlebar vibration frequency.
You owe NASA $4,687,254.78 for filing an erroneous report and testing.

The phone is being carried in a jersey pocket by Jeremy. Don't post rubbish without reading the original post.

I've made it a habit to hit (not hold) the power button before I put it in my pocket.

I have all my android devices set to turn off the screen with a double tap of the homescreen and it works flawlessly. Haven't had a butt dial or the phone navigate it's way through settings in a very long time. If using and returning to an app like navigation, I use your method.

My motorola never butt calls, in fact it doesnt like to wake up at all.
I like it that way.

Hear hear.. can be especially helpful if you're not smarter than your smart phone.

My general policy as well, but execution isn't perfect.

None of us are perfect

Not quite true...

Just for fun...

Does anyone know the story of the 'Birth of Cheez Its'? I hear their factory is immaculate!

Jeremy, my S24U has an option, which partly dims the screen and protects it against the unintended use until you slide your finger on the screen properly to unlock. Your app is on the top for the whole time (I use that option to protect a running game, which deprives me of the result unless it is on the top and in focus). I do not know the name of that option but probably you can find it yourself on the S25U?

P.S. Go to Settings > Display > toggle on Accidental touch protection.

Thanks, already using that, but still too sensitive.

The S25 Ultra's high touch sensitivity is a frequent annoyance — and a clear departure from the Note20 and Note5 flagships I had before. My only complaint with the phone.

As far as I can remember, the sensitivity can be reduced as well!

I've exhausted all available settings menu items, but perhaps there's another trick?

 

[Gionnirocket]

Have you tried increasing tap duration?

Additionally repeated touches

edit: I'll also add one thing that makes android much more user friendly to me is to use a third party launcher. I've been using Nova Launcher for over 10 years now and as far as I'm concerned it's way cleaner and neater than the Samsung UI that is geared towards 14 year old girls and social media.
ymmv

Settings -> Display -> Touch Sensitivity Off.
If done, there is only one way: Use a phone cover with a screen protector
