has anyone noticed that the 4G on the S10 is quite buggy?
the speeds are extremely unstable, and sometimes completely unusable. (not a problem with the carrier, tried it on another phone and it's fine)
What I've noticed is that if it ever goes into medium power saving, 4G will stop working completely, it'll still show 4G, and i can still make calls, but no internet connection, even after exiting power saving mode. The only fix is I'd have to restart the phone for 4G to work again.
anyone have the same problem/ knows a fix?
I've read that I should do a factory reset, but I really want to avoid that, setting up the phone is time consuming.
Side note: battery life is not as good as expected, but that seems to be an issue for all exynos, not just me.
Same Problem here i unlock phone 4G shows but it tanke some time if i can use the Internet
Speed is Very slow and unstable
I am having connectivity problems as well. Keeps loosing the connection. I have to turn on airplane mode then turn it off all the time.
I don't have any problems with network connectivity, so far. In the link my result a moment ago: https://www.speedtest.net/my-result/a/4796337263
Hope you get some sensible connectivity soon. Cheers!
Same issue here! It was fine since I first received the device, but yesterday, I manually changed the network toggle to get better indoor signal. However, even after setting the toggle back to the original setting the LTE and data service kept dropping out. I tried manually toggling, switching network bands, etc... but nothing worked. It just keeps dropping data service.
I just hard reset the phone moments ago, and will update accordingly!
Update - Even after a network reset and hard reset it still dropped to Edge data a few times. However, after the last hour or so, it has locked back on to LTE+ and is holding strong. Seriously hope this is a software bug and not a bum radio chipset or antenna.

I'm on tmobile and my data is horrible in certain and what's weird I have all bars.

not sure if i should say that its good to know I didn't get a dud.
but man, samsung needs to get their sh*t together, this is not acceptable for a flagship phone.
looks like i'll have to do a factory reset soon.
I'm on tmo as well. I have a feeling it's just jacked up radio software. I did some more tweaking and went into band settings *#BAND# on the dialer and disabled all the LTE bands that aren't used by TMO and that seems to have helped as well. It think this issue is congruent to the known issue with Sprint devices trying to connect to incorrect bands. I haven't used it out and about yet, but it definitely helped my phone stay latched on to LTE from my home. Additionally, when it does drop to HSPA, it doesn't get stuck like it used to.
I recommend tweaking the band setting before doing a hard reset.
Update - still doesn't fix the problem. Pains me to say it, but I'm afraid I have a hardware issue. I'm going to try a sim card swap as a last ditch effort, but will also seek an exchange as well just to get ahead of the problem.

This shortcut only works on Snapdragon version, do you have Snapdragon with 4G issue?
This code only runs on the Qualcomm chipset version. Oddly enough, my friend with the Exynos version has no problems, even though he's missing a couple of TMO bands for the US.
Yeah I have Exynos S10+ as well and it runs fine on T-mobile USA

This code is not working on SM-G9730 Qualcomm Hong Kong version. Any ideas?
Same problem here. I got the snapdragon US unlocked variant using here in Spain and compared with my old Google pixel, they do not have the same speed LTE connectivity even using the same SIM card. I tried to force using the 20 BAND (800 MHz) but I dont really know how. My galaxy s10 plus is using the BAND 3 so it does not let it picking the fastest possible band in my city. Any ideas? I also did think galaxy s10 plus US variant did not have 20 LTE band, but I checked it and realize it even does. One more question, what is the difference between 4G and LTE? Here in Spain all devices are running 4G, not seen any device running LTE, but my new samsung does. How can I switch it to 4g or LTE+? Thank you everyone boys.
just wondering if anyone has gotten the ASCA/ASC8 update and can report whether this problem is solved wit firmware update?
Bands matter depending on where you are. Depending on your area, only specific bands will be used. However, some bands used, while not faulty, are easily interfered for some reason with cases or other obstructions like your hand. Most likely, Samsung is planning to give a large update considering signal direction. I would probably not factory reset if you have a lot of data, and the problem would probably come back.
I ended up having to send my device in to Samsung for analysis and repair. I'll keep everyone updated.
after ASC8 update, i think the problem has been solved, havent noticed any problems so far
So I got a Chinese edition phone with band 2, 4, 5, 12, and 17 to fully support both TMobile and ATT network. The Global edition was missing band 17 for ATT so I didnt want to go that route. Been going back and forth with ATT a bit for the past few days since my device came in. The phone shows up and an "unknown device" on their network when we tried adding the IEMI. It will get UMTS (2g) and HSPA+ (3Gish/4G), but will not connect to any LTE or GSM. The phone supports GSM fine, so its strange that it wont do normal cellular connection over that, it will only do cellular over UMTS. The device wont detect as an LTE device and so the sim wont activate LTE on it.
Anyone else with ATT have this issue? And were you able to resolve it somehow?
Or those with TMobile in the US, are you able to activate the phone fine and get full coverage and LTE working?
I messed around with the connection settings in the *#*#4636#*#* menu. Only the "LTE/TD-SCDMA/UMTS" and "LTE/TD-SCDMA/WCDMA" will work properly at all. Both options give me UMTS for cellular, and HSPA+ for data. Of the 4 APNs that ATT uses, only the "ATT Phone" will work at all. The standard LTE APN "NXTGENPHONE" will leave the phone with no data or cellular service. This is related to the phone not being detected as an LTE device and the SIM not activating as such.
I simply put my AT&T sim in my China version and it worked straightaway. I didn't have to do anything else.
I am on Cricket, which leases service from AT&T, so I should know if it works once it comes Tuesday.
Just for perspective, I got a EU version of the Mi 9. Popped in a T-Mobile sim and it worked out of the box. Try the other sim slot. Could be your sim card if not.
Try these codes in Dialer. See if that helps anything.
VoLTE *#*#86583#*#*
VoWIFI *#*#869434#*#*
I was just making an ATT account so no previous activations or sims. So that could be the issue. I will try activating a sim with an old phone and then move the sim over. Or since it is the same hardware as a Galaxy S10, ill see if I can find a store that will activate a sim with a floor model S10 and then let me swap the sim into my Mi 9
Straight talk (ATT sim) lte without issue. no programming necessary , I have the global model though

Where did you guys buy the China version from?
US mobile white SIM from starter kit (T-Mobile) works well with LTE on Chinese model of Mi 9. Black one (Verizon) technically works, registers in the network and enables data, but Verizon refuses the IMEI as non-certified brand of the phone. Trick with activation on the iphone first and switching to xiaomi did not work, service gets cut off, when trying to make a call, it keeps dropping. AT&T based: Cricket and Straight Talk work just fine too.

Thanks for the info.
I was wondering about Verizon, since it support some CDMA bands and support 2 out of 3 of the LTE bands they use (doesnt support B13). Unfortunately I never tried it myself since half the coverage near me uses the band this phone doesnt support on Verizon.
I went and got my ATT account updated to an old Nexus 6 IMEI number and it got LTE on the N6. I then took the sim and put it in my Mi 9 and now the Mi 9 has LTE. So for anyone just getting this phone, you must have an IMEI on your account that is recognized as an LTE phone. If you try to add the IMEI of the Mi9 it is not recognized by ATT and wont provision LTE.
IMEI spoofing does not work with Verizon, as they simply ban the device. They call it “non certified”. Bands are seem ok.

I been purchasing from liaow. Never ran across a issue with them
I've been having the same issue, with a recently-bought (last week arrived) Mi 9 Global on AT&T postpaid. LTE showed up and worked fine day one, now network speeds are dropped down to 3.5G speeds. Anyone else have success with getting LTE on a fresh SIM?

I got the Chinese version and I'm in the US. And I I have the straight talk T-Mobile sim and everything works like it is suppose to expect my internet. It says its 4g but it is very very slow. Any ideas?
Just got my Pixel yesterday, noticed that I don't have any sign of 5G connection even if I have everything activated on my sim and used 5g in my area with a Huawei P40 Pro....
I noticed, when I accessed the *#*#4636#*#* menu that it shows my sim card as sim2. I know that on second sim there's no 5g and I wonder if that's the problem. If it is, is there a way I can solve it and make the phone see my sim (physical, and my only sim) as sim 1?

Yes, tested with P40 Pro, working. Here's the Pixel
https://support.google.com/pixelphone/answer/9449293?hl=en
Do you have both SIM activated? It says "Pixel 5 and Pixel 4a (5G) phones with two SIMs in use will fall back to 4G networks. To connect to 5G networks, temporarily turn off the SIM that isn't set to use data."

Nope, I don't have both SIM activated. I only have a physical SIM that's in the phone, no Esim and still, it shows it's SIM 2. That's why I asked if I could reset or something and make the only sim I use SIM1, I suspect it has something to do with the phone keeping 5G off for it.
Hello balenax
I have the same issue I am based in Kuwait. They told me that my carrier needs to do some configurations with the manufacturer (Google) and then google will enable it with a software update. The physical sim I installed says Sim 2 similar to yours and once I tell it to use NR only the Network goes away instantly. I will play with 2nd sim and tell you if something happens. Please do update me if you try something

Yes, I think it's similar to OnePlus 8, the 5G connecting is enabled only for some carriers. It's a matter of time (hopefully) but I'm afraid they won't do that for unsupported countries (I'm from Romania and Pixel is not sold here officially).
Our best bet is root and edit the carrier policy files, just as on OnePlus.
I'm not that eager to do that, I'll wait for a while and see, maybe it will be solved by Google and operators.

Yes it's the same for all 5g Androids and unsupported countries, unfortunately. It is really frustrating since the bands are supported. Only Samsung, Apple, and Huawei devices are supported everywhere since they make deals with everyone. I hope this 5g mess gets fixed soon. I am not a fan of rooting my Pixel. I am hoping it will be fixed by beg on Next Year. I just tried installing an esim but it shows up as sim 3 so there seems to be something blocking the use of sim 1. It would be interesting if someone with 5g working to give us a screenshot of the Phone info I suspect that they will be on Sim 1 . If yes is it region locked!

I have consistently used unlocked devices on the AT&T network OR used U1 firmware on a U-original based carrier device. In the past I have had to flash additional things to the U1 firmware to get VoLTE or WiFi Calling on AT&T. To do that I would flash the U1 firmware and then flash the U Home CSC
BUT -- good news (this is the first Samsung device to do this for me) the ATT calling features (VoLTE and WiFi Calling) work right out of the box for my Unlocked Ultra !!
Wow.! Great to hear. I was going to get the ATT S21 Ultra in 512GB but they were sold out at Samsung, so I got the unlocked version. I am glad to know I won't have to jump through a bunch of hoops to get those features. Now on to get a working Gcam and debloat things I don't need

So here's what I know from prior experience. You are on the wrong plan. As so as ATT puts you on the right plan your APN will immediately automatically change and 5g will work if it's available.

well I called ATT like 10 mins ago to find out why I`m still not getting 5G, I told him I try to enter the ATT enhancedphone APN and it wouldn`t save in my phone, so goes well lets go to the APN settings, so I went to the APN settings, low behold the the APN had automatically changed to the ATT enhancedphone APN, so as soon I saw that, I turned off my wifi and boom I had 5G, I know I had the unlimited plus prepaid plan that`s the only plan that allows 5g access, I`m thinking my plan wasn`t fully set up correctly on ATT end, but its fixed now Thanks for the info.
Do you guys actually have VoLTE working on the S21 Ultra unlocked? I don't have any options for VoLTE on mine.
WiFi calling showed up for me when I got the phone but not VoLTE. I went to the AT&T store and got a new SIM card because the WiFi calling wouldn't actually operate. This fixed WiFi calling but still no dice on the VoLTE. I also switched to a 5G plan which works as well, but that didn't resolve VoLTE either.

Hi, I updated to Android 12 when it was released, and it seems to have broken 5G NSA support on T-Mobile. With non-standalone in my area, I'm able to connect to midband 5G and get excellent data speeds. After the Android 12 update, it seems to prioritize standalone (SA) lowband 5G, which is often even slower than LTE, and I have not once seen it connect to NR NSA. I never encountered this on Android 11, but don't want to reflash my phone just to troubleshoot. I'm wondering if anyone else has encountered this issue. Thanks!
what app are you using to get the connection info? i have yet to find a network tools app that handles dual sim phones well. a few apps state android os itself dropped 2 sim support after android 9.

I'm just going into Settings -> About Phone -> SIM Status. It tells me the type of connection for voice and data. If I were on midband, it would show LTE for Voice and NR NSA for data. But it's showing NR SA for both, indicating my phone is on lowband.

ok. i just got a straight talk t-mobile sim activated this morning and i show LTE for voice and NR NSA for data network type. i've done a few speedtests and it's been between 130-150Mb down with 30 Mb up. however, google fi which is same t-mobile tower gets over 200Mb down /30Mb up. so it just appears to me that t-mobile gives a sweeter deal to Fi than to straight talk. but that's just one morning and a couple tests.

Hmm, I'm on a normal T-Mobile plan, but I'm not sure if that would make a difference. Are you on Android 12?
This issue only showed up for me the day I updated my phone. I don't think I dropped it or anything, so I doubt it's something physically wrong with it. But I don't want to unlock the bootloader, wipe my phone, and roll back to Android 11 just for troubleshooting.
Figured out a solution. I stuck in my mom's T-Mobile SIM, which is much older and doesn't support standalone 5G, and it connected to NSA. So it's some software thing where they're heavily prioritizing SA 5G over NSA, even when NSA is available and SA is garbage.

Yes, android 12. As well as a new sim. There was some mention by T-Mobile of having a new sim for the 5G. I have no idea if s new one is required, just that they said it in the materials they sent me that 5G would work best.
I have T-Mobile and am getting great service with 5G where I am. I have just recently got it connected though, and I was already on Android 12 when I had it connected for service. Not sure if that matters though?
I use Mint on T-Mobile towers. I just upgraded to Android 12 OTA, and with the adaptive connectivity setting enabled I see LTE as the mobile voice and the data fluctuates between IWLAN and NR NSA. I have wifi-calling enabled, with mobile network preferred. I didn't pay attention to this status screen in the past, so cannot say if anything changed really...
