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?

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...
Does anyone else have problems with slow LTE speeds. From my experience ithey are halved from what i get on another phone with the same sim. i have the unlocked 21+ straight from samsung. snapdragon.
does anyone have a possible solution for this problem

Hi
Mine is working fine s21+ exynos, test the speed and compare with what the ISP offered you, check here or here
Try a network reset.
I could say I'm also a bit disappointed with the LTE (4G) connectivity. I put the same sim card (TPG Singapore) to my S21+ (Exynos) and my old Huawei P20 Pro and tested. On S21+, the speed is 56Mb down, 4 Mb Up. I thought it's pretty ok, until I try with the old P20 Pro, the result is 75.1 Mb Down, 5Mb Up. Testing with the same sim card, placing the phone on the same spot on my table. At least, it's still better than my wife's OP7T, so I won't make much complaint here.
And reception-wise, While I got a full bar reception strength on the P20 Pro, I only got 3 bar on S21+.
But where the old P20 Pro can't beat S21+ is the Wifi Speed. Connected to same home wifi (Gigabit Wifi with 1Gbps fiber line), P20 Pro yield only 430Mb down and 333Mb up, while S21+ yield 450 Mb down and 530 Mb up.

thanks for your inputs. I am getting a new sim to see if that does anything. I tried everything else and nothing works. As for the wifi it is also weaker at least for the 2.4 ghz. 5 ghz is fine. It is ok at home but a lot places I go to do not use 5 ghz routers yet. 2.4 ghz speed on my s21+ is 10mbits while on my pixel 2 and poco x3 is 100. While on the 5ghz spectrum they all get the full speed of about 220 mbits.
Hi,
I am not sure whether is this Andorid-related, Samsung modem HW related, or even my ISP host related. Well, let me describe and then move on.
I notice when I am abroad, roaming, that when I go into low signal area and ROAMING (foreign operator) signal is lost, then my phone does not recover back ONLINE when I get back to area with excellent signal. In such situations my phone number will be unavailable even for whole day, if I do not notice. Very annoying, because I need to constantly pull out my glasses to see that tiny signal icon, check signal, whether I ma online or not, and if not, reset. Or use workaround instead of reset, to turn airplane mode ON then back OFF to reset signal, and voila, I am accessible again for calls and messaging.
What I tired already:
first, I checked with my wife, she has LG G7 smartphone AND she is subscribed with another ISP, and she does NOT have any similar problems. we are traveling together to those areas without signal and back to civilization.
then I sent my Samsung Galaxy S10 to service, and of course, they did not find any problems
then I changed my SIM card for new one, but no difference
then I got angry and bought new Samsung S21 Ultra...but first trip abroad, roaming + to areas without singal, same issue again, only me, my wife no problems
So... any idea?
Is it Samsung, my ISP operator (like, maybe they have some weird roaming algos?), or Andorid 10 and 11 bug?
S21 ultra is a terrible phone, it does take nice photos though

s21 poor signal strength
I've just upgraded to the s21 from the s10. Problem is that I now only get 1 bar showing on the signal strength most of the time (including home). On the s10 it was on 3 bars most of the time using the same network and SIM. If I swap the SIM card back to the s10 I get 3 bars showing again I...

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?
Hello, I need help
I have a US S22 Ultra. I unlocked all the 5G bands so I can use 5G Here in the Philippines. This was working for me for a few months now until an update broke it last week. Tried reformatting and flashing the firmware then redoing the instructions and it's still broken.
What's happening now is everytime it switches from 5G to LTE or vice versa both sims loses signal for 10-15s this happens multiple times a day and my battery depletes like crazy and my phone gets hot.
Attached a screenshot below of what it looks like when the signal drops. Using S22 Ultra SM-S908U1 (XAA) with one physical sim and one e sim
Thanks!

After you did all the steps , was the sign showing for 5G or it stayed LTE but with faster download speed?

It was showing 5G
Ok, But for me it sticks to lte or max i have seen lte+ but only for few seconds, but i still feel there is a lot of issue when i am on the move as internet is laggy and slow
