phone randomly alternating between 5G/LTE

I'm on T-Mobile and I've noticed my phone alternating between 5G and LTE at random intervals. Both 5G and LTE are at 4 bars and I'm stationary. It's not really an issue because I didn't get this phone for 5G and the connection isn't dropping when it switches. Is anyone else experiencing this?

Actually mine has shown 5g constantly since I got it. Even though it's not using 5g. Mine is fully converted to TMobile

Mine is doing the same..... it must depend on signal strength or something. What concerns me about it is that 5g and 5g mwav is suppose to have less issues with walls, so why are the phones not staying on 5g? something is causing the 5g signal to go in and out.... I noticed less of an issue outside than inside which would be normal I guess, but should not be an issue for Tmobile's 5g service.

I live in NYC and don't have this issue with my phone. Could it be a problem with your location/city?
Have you called t-mobile about it yet?
Maybe do a speed test when it switches to see if you get lower speeds on LTE, maybe that would show if it is really actually switching or just an icon issue as both have the same amount of bars.

How are y'all determining that you are actually connected to a 5G carrier ? For AT&T, they have put the 5G icon on the man screen for awhile so I was looking at the Mobile data network setting under SIM card status but have only seen LTE. Having said that, I have done speed test where I am getting 20ms latency and 60Mbps download speeds.
Here is where the old Nokia Field Test Mode would be useful.

Because, up were you have the bars that show how strong your signal is, it actually tells me when I am on 4G, 4G LTE or 5G, and at least one Tmob, do don't need a 5G enabled SIM, it should "Just work" if you have 5G service in your area and you are within range of a 5G equipt tower..... I also checked with apps like Open Signal and others to see what towers I am connecting to, etc.
5G download and upload speeds are crappy though....lol..... Should be broadband speeds and it is no were near that...

Question Cellular network

How is your cellular network connection? I have noticed i miss connection some times.

Mine has been fine, same as my previous Pixel 5

Do you live in a larger City? No problems with my op6 here i live, somewhat spread 4g.
Concerned if i need to deliver it in, or if it can be fixed with an sw update.

No. I live on the edge of a large town.

My S21 on T-Mobile has been a damned disaster. Can't hold a 5G signal to save its life, and I have 4 other 5G phones next to it locked onto 5G, getting 4x faster speed tests. I'm hoping the Flip performs better.

I believe the S21 has the same modem as the Flip 3.

Me too!!! I'm finding that I have no connection or I am roaming in places that I had coverage on my S9. My wife's iPhone SE was staying on Spectrum while I was roaming. Thinking about sending it back.

Yes i am going to deliver it in, cant check bank app when in stores. Only have edge coverage where i usually have 4g.

Question S22 Ultra signal problems

do you guys have signal problems?
i think my S22 ultra has signal issues. signal bar is always with two bars, even sometimes one bar
in same place, same operator, and same sim card, i have full signal bar with other phones and internet is 4G
another problem is, for example, we're outside of city with friends, my friends have 4G internet with their normal phones, but my flagship s22ultra goes to H+ or E internet
can anyone please confirm these problems with signals in s22 ultra?
mine is snapdragon

See my post here: https://forum.xda-developers.com/t/ultrawide-band-antenna-failing.4480749/#post-87292505
It may be this. I assume the issue is bigger than currently reported and people assume its their carrier.

we are not wizards
what state\city?
att or tmobile?
airport or power station near your home?
whats your case?
firmware?

A71 5G signal drop out

I have a sm-a716u1 or a71 5g. I have noticed that when my signal gets low (4g 1 bar antenna) if I'm holding it in my hand it seems to get slower and more so. If I put it down , most of the time it will jump to 3 bars antenna on 5g. This is the second a71 5g I've had to do this. The first one is rooted, but this one is not and it's had every update. Has anyone else had this problem?

Question network signal - weak

hello ,
i have s22 ultra and I have al the time the signal is very weak !!
at home 1 and in malls it seems to be 0 and all most of the time 2 or 3 bars only
I use 4g lte network
any suggestions or mod or setting to rise it up or to know the problem !
( I try the sim with other mobile its better then the s22

Call your provider, and have them do a network refresh.. I had to do that when switching from Sprint to T-mobile on my S9+. I could not get data to save my life, and had a lot of dropped calls.. Once the refresh was done, all issue went away and have not had a single since.

move to MINT mobile

do you have the exynos version because samsungs own modem is not as good as the x65 modem on snapdragon

Both WiFi and phone signals, are much weaker than my previous OP7+

my S22 Ultra has a remarkably better signal levels, cellular, wifi, gps than my previous device, a Note 10+, full bars almost at all times all over the city, even in malls or inside buildings, my devoce is snapdragon

Are there some measurements available or is it just what Qualcomm promotes?
