Is this normal for T-Mobile devices

[werkx]

I'm new to T-Mobile so wondering if this is normal? I have strong Wi-Fi signal but notice that the 4G LTE icon would occasionally pop up.

I understand that when wifi is weak the radio would switch to mobile signal. So I started the speed test app and Wi-Fi strong, see screen capture.

Yeah that's normal always happens on my Samsung on T-Mobile

That always started to happen from when I bought an s10+ on T-Mobile, wasn't like this with my note 9.

Happen on my note 9 also ..I tried to figure I out no luck

Maybe it was the note 8 then lol

Edit , was yours a factory USA unlocked model? Or TMobile.branded?

That one didn't own

Just seen your edit , definitely happen unlocked and carrier firmware ...I flashed between them a lot

Realize that wifi and cell signal are two separate things. They operate completely independently. The display isn't telling you which one you're on; it's just telling you the signal strength/status of each system, independently.

Is this a problem for you?

 

[werkx]

I don't see it on my factory Unlocked
With Tmobile.. !

Mine is the T-Mobile version, and it only comes on occasionally but more so lately. Maybe I'm just noticing it popping up more than before.

Not a problem in regards to data usage against my account as I have unlimited. It just seems to indicate the device may not be hold a steady Wi-Fi signal, even when strong, so is using the mobile data signal in conjunction. Or, maybe it's an app running in the background that is using the mobile data instead of the Wi-Fi to get around my personal network.

Just wondering as to why both data signals are being used by the S10.

Wait a minute--why do you think that what you see means "both data signals are being used"?

Both icons have up/down arrows that flashes, which I assume shows the flow of data through that particular network.

 

[Adam Frix]

Ah. You picture didn't indicate that the cellular arrows showed usage.

Regardless, the cellular network has all kinds of housekeeping to do that's unrelated to you making a call or an app using data. And what you describe is the signal waxing and waning, and sometimes presenting 4G and sometimes not.

It's no mystery that the cellular portion flashes, and it doesn't mean it has anything directly to do with your current usage.

Yeah, I see your point. I came from Sprint and this, both Wi-Fi and 4G LTE, icons never showed up at the same time unless it's switching from one to the other.

Also, you sound like you have some knowledge in this area, may I ask what experience?

 

[methodman89]

Have you looked at Advanced Settings in Connections?

Right. It wasn't switching. My wifi signal was strong, see speed test pic. The Wi-Fi icon stays and the 4G LTE pops up along side then go away after a few minutes, then back then gone...

 

[mustang7757]

Exactly , try turning data off for TMobile app by long press it then tap Info scroll to battery turn off data and background

 

[Rukbat]

My wifi signal was strong, see speed test pic.

High speed and high strength aren't the same thing. If you're near the router, the strength will be high, whether the internet connection is good or terrible. Conversely, if you have a weak WiFi signal, but no interference, you can still get good speed. If the signal is strong enough to capture the noise or interfering signal, it's noise-free and interference-free. Signal strength only matters when it's at the point that, any lower, it's going to drop out. With a digital signal you have either full signal or no signal. (If you ever see the signal "going digital" on TV, you'll notice that it's a small portion of the picture it happens to and only for an instant - a noise burst is as long as part of a single scan line. When the signal gets worse than that you're left with a 'still' of the last frame the set received, but in a cellphone, once the sound is over, either you hear the next one or you hear silence. [Not to be confused with the 'underwater effect' you get with CDMA.])

Sounds like it is behaving normally if your settings are as pictured above.
Background cell data use in this state is to be expected, unless you do as Mustang has advised.
