Sometimes my Samsung Exynos s20 5G disconnects from the Wi-Fi without any error. Can it be an issue with the chip of is something "normal"? I have it updated to the last build with version 11 of Android. To make it work again I have to turn off and then back on the Wi-Fi some times. Any ideas if it's caused by some issues from the factory?

I'm coming back to my Note 3 from a couple of months on the iPhone. I rooted the phone and installed SlimRom. Only issue I have is that the phone only detects my WiFi 2.4G and not the 5G.
Is there a solution for this or does this type of rom not support 5G?
Anyone else notice that after updating to Android 10, all the necessary Wifi Calling software is just baked in now?
I have the korean SM-N976N , Note 10+ 5g and am on USA T-Mobile. Now, on the Korean Note 8 I had to make a custom CSC patch which included some software from the F variant as well as the U T-mobile variant (as well as delete a Korean feature) to get Wifi Calling working.
However, on this 10+ 5g I haven't had time to root or work on a CSC patch to get WFC, but after updating to Android 10 a few days ago, it is just baked in by default now and works just fine. I did have to go into the Wifi Calling menu and change the preference to Wifi, but it is definitely connected and works great.
Now I'm really not sure rooting is even worthwhile anymore... adblock would be nice and CSC feature customization is also great but... everything just works now (minus phone-app Samsung Pay of course, but rooting wouldn't solve that).

Anyway - anyone else notice this? Wondering if AT&T WFC will work now as well.
KT- Hey! I ALMOST got a Exynos Note 8 a while back, based on your experiences fixing it for T-mobile. Now I'm seriously considering the Note 10+, because it seems even more US friendly.
There's been some talk about Carrier Aggregation. Has there been any progress? Does it REALLY matter? How slow is "slower" gonna be? Would I notice if I didn't have a US version right next to me?
I'm actually thrilled that the Wifi calling just works now! That becomes a huge issue for me once a year, when I travel to the deep Boonies to see my family.
Also, I'm thinking of getting the F/DS. Would it be better if I track down the N, like I believe you have?
Long time listener, first time caller. Thanks so much!
How has your service been? On my N975F, its been ok. Slow data speeds, and weak signal, have been issues ive been dealing with. Im also using on T-mobile in the US.
What about 5g? Did u managed to get it working? I live in China and technically n976n has to work on n78 band but it doesn't
I have a note 10+ 5G TMobile and it looses internet quite often on cellular and wifi is stuck at checking connection quality.
Reboots also take a long time and hang at the Samsung bootscreen.
On latest TMobile update.
My regular note10+ works just fine. This 5g version is really broken.
These devices are sometimes a complete mystery to me. I recently bought two Redmi Note 9T devices for my household to take advantage of 5G, which they do beautifully. But here at home 5G is spotty, at best, so 4G LTE is what gets used most.
However, my device frequently goes to LTE+ while my partner's never does, and since I'm the "master configurator" for the house I know that I have never done anything with settings that should have this end result.
I have the same issue as others have reported in that the signal strength falls so substantially when the switch to LTE+ occurs that the hotspot is useless. It always resolves when I reboot the device, and it will stick with LTE for many hours but, eventually, it will always revert to LTE+.
Is there any way to prevent this without using the previously noted app? My phones are not rooted and I really have no desire to root them, as there's no need otherwise.
Both devices are running MIUI Global 12.5.2 over Android 11 with the 2021-05-01 Android security update.
P.S. Sorry for necroposting, but this is one instance where the topic is already perfect, and things do change over time.
Hello All,
I have been facing a weird issue with my phone. What happens is that my mobile data randomly stops working. I will see the sign in the status bar but the arrows that show that data is being sent and received (for the internet to work) only shows the sending/uploading arrow and not the receiving/downloading arrow.
I am unable to recreate the issue on demand it just happens randomly. I have tried everything on the internet and so far nothing is working right now.
So now I am asking the xda community for support.
Let me know what info I can provide further to help diagnose this problem.
Thank you.
I have seen this problem in other S21 FE and even in the snapdragon variant, there is no solution yet, only apply warranty.

Went to Samsung and they are saying there is nothing wrong with the phone. How to claim warranty?

Same issue I am facing with my Samsung S21 FE(Indian variant). In Samsung community, multiple people have reported the same issue for Galaxy S21 Ultra(Exynos variant).
S21 ultra mobile data issue. - Samsung Members
S21 ultra mobile data not working. - Samsung Members
S21 ultra Mobile data problem. - Samsung Members
Dual sim mobile data issue still not resolved. - Samsung Members
The only workaround I found was to disable the second sim and then data was not getting stopped randomly.
I have submitted this issue along with logs in the Samsung members app multiple times. But there is no confirmation about this issue or fix plan from their side.
It's really annoying that a basic feature is not working properly!!!
Dec 2021 I brought a second hand s20 FE 5g. Everything was good in that phone except network. It had no proper carrier aggregation support even though it had when it got released! Sold it immediately because of network issues. What is the use of phone if it doesn't do its basic job like connectivity properly. Brought s21 FE recently thinking that samsung might have done some work by looking into their previous failure. And they indeed did! For 3 weeks that is!!! Now, Forget about CA. Can't even use 4g internet properly. Even with single sim! Internet suddenly goes on strike for no good reason. Have to toggle Aeroplan mode on/off. I still don't understand samsung. They know that they need work in handling network properly and yet they ignore it. My 4 year old Redmi note 7 pro which I brought for 8k gets continues CA with same sim in same area and a 55k so called flagship phone can't handle that properly! Hats off Samsung.
Same thing is happening with me, it happens only for second sim.
I wish Samsung fixes it with the updates.
Using exynos version
Posting here a quick fix, may be it'll help someone.
If you are using two sims and facing this issue.
Recommendation is to switch one sim network to 2g/3g and keep the other data sim to 5g/lte/3g/2g, it'll fix occasional disconnection of network.

I'm using single sim in my s21 fe. Thought of putting other sim from my redmi phone but now i'm getting better internet in my 4 yeal old phone than this pathetic piece of ****. Sadly both of my sims are of jio so can't use 2g/3g mode.
