Question Sometimes 5g does not deliver internet access - Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40

Hello friends!
Some times 5g is not delivering internet at all.
I mean I may walk for 10 or 15 minutes with no Internet at all.
Whenever it turns again to 4g internet access is back again.
So any ideas on what is going on with poco f3 and 5G?
Thank you!

not to be a D-bag but you might want to include your region carrier ect...sounds like a carrie problem to me ,,OFF THE LITTLE INFO YOU PROVIDED...

This probably won't do much, but did you check the setting "5G Battery Saver" in the Battery Settings ? Maybe that causes problems?
I'm just guessing tho ^^

Getting data connection after Wifi takes very long

Hi there,
if a were in wifi with my G3 and got out of reach, the device needs about 20 to 30 minutes to establish a connection to mobile network. Thats really annoying and I'm wondering if thats a hardware problem. Is there something I can try to fix it before returning it to the shop?
Thank you very much!

Help please. WiFi speed is really slow on 5g

Have 250Mbit broadband and with my Samsung I get full speed (I'm in the same room as router) but with honor 8 pro I got 140Mbit o my one time. Now it's so slow as 7Mbit.. Tried reseting device several times.. And in WiFi settings I have excellent connection. It saying 433Mbit but on Samsung it says 768Mbit.. Please help me out? Kind regard Dexter
I'm suffering the same issue! 5G speed slows down till it switches to mobile data or just gets stalled, connected but without data moving at all.
Not related to my router, because I've "enjoyed" this issue at home, at the office, airports, friend's places... Always the same behavior: speed goes down till no data flow at all, but still connected to 5G WiFi
I am also facing same problem what happens with honor ui i contact to customer support of honor they told me that u have to hard reset the device by in booting menu then i got fine but after 2 days wifi speed goes down on honor 8 pro seriously then I'm waiting for developers rom but there is no official rom available for this device :crying:??
Same here.. I've got Netgear r6220 router and the max link speed i m getting is 390mbps on 5ghz.

Cant use mobile internet whıle on call

hi there,
i am new with OnePlus, and am i really so happy from that decision.
just i need one strange question. While on phone call i cant use internet connection on my both service provider ( different gsm companies btw ). even my old M7 was able to done that. have i done something wrong on settings? or this is like that?
thnx
regards
I can't use internet while on call me neither
No issues here. But I'm using a single sim for both data and call.
Iam on OOS 8.1 beta 4 using 2 sims, same can't use 4g when on call but only sometimes I have noticed my 4g drops down to 3g while on call, there should be a solution to this, I am gonna try some 4g booster apps from play store lets see if they help, cheers everyone.
Don't think this is an issue. I don't recall I could do this ever on any phone. But if you are connected on wifi there is no trouble at all. Guessing you can't do both ?

there's an option in "developers options" "mobile data always active" , if u read the little detail underneath it it says mobile data will be on even if the WiFi is connected I presume this way both will be on, but I still don't know if mobile data disconnects at the time of making a call, but I will experiment and see what happens, cheers.
I had the same issue on my OnePlus3 a while ago. I haven't encountered it on the 5T though. I'll try to look for a solution when I get home. In school atm.
I'm using turkey Vodafone and when I'm on call i can use internet but it drops to 3g from 4g, unless you use volte its normal when it drops to 3g.
Yep definitely an issue. I'm Virgin Media and EE
Don't remember it being the case on the OP3 but could be wrong
On op3 I remember having the same issue. And note 3 and note 1 too. That's why I don't think it's an issue per say. Maybe a wrong implementation or something. Can maybe be fixed by a piece of code (magisk or xposed)?

Question Mobile data interruptions on POCO F3 - is there any cure?

Hello, I tried searching on XDA and elsewhere but could not find an answer so I hoping to receive help by writing my issue here.
I have bought two POCO F3's 128GB & 256GB on Amazon & Aliexpress respectively.
They both have the same issue when using mobile data (4g) loading websites and doing voice & | video calls like FB messenger there are interruptions like for a second there is no sound or video freezes. It does not happen on wifi or other phones.
I tried resetting APN, selecting proffered network to LTE, rebooting, switching SIM slot, resetting wifi, mobile and bluetooth settings. Updated both phones to MIUI Global 12.5.1 still no luck.
Country Lithuania (EU) carrier TELE2
We really like the phones, but this is pretty annoying as we do a lot of video calls due to quarantine and what not.
Amazon suggested to replace the phone but seeing as two of them having the same issue it will most likely will not help.
Anyone experienced these issues and came up with solution?
From what u described, seems to me is a bandwidth/mobile data speed problem. Looks like is not enough bandwidth for video call to work properly. So, what is ur bandwidth provided by ISP? What mobile data plan had from ur telephony provider? Maybe ur mobile data signal is low in the place where u make the call from. It can be so many reasons for the issue u confront with, other than a problem with phone itself (a hardware/software issue).
you can also try the latest china stable firmware 12.5.4

Hi, ty for reply. That should not be an issue, reception is great and we tried it in multiple locations. Our previous devices Iphone 6s/ Poco F1 worked flawlesly with the same carier.
Here is speed test done on mobile data.
Any other ideas?
Found this thread here and I found a solution. Apparently there's an issue with network interruptions in general, especially on phone calls. This can be avoided by switching on VoLTE and WiFi-Calling. This is what I found out over time.
Here's the fun part though: Through a little bit of research this turned out to be a vodafone-problem. I am just guessing you guys will be either also on vodafone or on the corresponding bandwidth in your country.
It seems to be a bug in the F3, but also something that happens when VoLTE is not activated for your SIM card. The phone will try to use VoLTE and this connection will fail, forcing the connection to reset. It will be back in 10-20 seconds, but this is of course super annoying whenever a stable connection is needed (like phone calls...)
Enter *#*#86583#*#* (86583 = VOLTE on dialpad) on your phone. and it will give you a feedback that the carrier check has been disabled. Note that this doesn't mean that VoLTE has been disabled. Checking the network for the capability is disabled then, which makes the setting visible on the SIM card settings. Same works for VoWifi btw.
Try playing around with those settings and see if the connection drops persist. I have no logical explanation why this is happening because what I am telling you is obviously call-related - and I do realize that what you're describing is about the data connection. For me this was related however and solved my issue.
Possible solutions:
a) try to get your service provider to switch on VoLTE for you (this worked for me). You're going to need to call support for that. They will reset your SIM card in the process. Reboot your phone and be done with it.
b) If a) is not possible, deactivate VoLTE in the menu that you activated with the code above. If you're lucky, this will stop the phone from trying to get this type of connection working, even though it's not available. This is broken exception-handling on the phone's side and Xiaomi promised to fix it. They are aware of the bug (since Aug 20th btw) and promised to push a fix into the next MIUI release
c) play with the settings and try to get the phone to not use alternative protocols, just 3G and 4G, also deactivate Wifi-Calling.
Hope this information will help somebody. If all goes well, Xiaomi will fix it and this will behavior will be gone in the next release.
same issue for me with 12.5.7
data interruptions all the time and full signal loss
very disappointed with this device from the day i got it.
O thought I'm the only one facing this problem.
It's so annoying to get an interrupted connection in the middle of the game.
not only game, and calls, i have too much trouble to get throught a call.
Hello all,
i was also affected by a similar issue.
In my case the symptoms were:
On mobile data/5G some apps would be accessing the internet but others wont..
I was able to overcome this by resetting the access point settings and then applying the ones found here:
Cytamobile-Vodafone Cyprus APN Settings for Xiaomi Poco F3 GT - APN Settings
apn.how
I hope it helps...
My fix for this occasional issue is to set the phone to '3g' only in network settings, then flick it back to '5g'. It seems to be area specific for me. Very bizarre.

I have the same problem, it helps to have the settings volte and vowifi enabled. Sometimes it looks low cell signal and loosing the connection.
Has anyone return for service the device?
It looks like we still have this problem, my F3 modem is crashing every few hours especially when it switches bands, very annoying.

It really is! We need a bug bounty for this
Hey I ran into the same problem in Hungary Vodafone Poco F3, 14.07 MIUI
4g net is working flawlessly but
Network connection is lost when start dialing
Nobody can reach me on phone
Enter *#*#86583#*#* (86583 = VOLTE on dialpad)
VoLTE select option turn on/off
Enter *#*#869434#*#*
VoWiFi select option turn on/off
I tried to switch on/off both but no solution just yet
sby has answer for this?
Where should I post this problem to be solved?
I also have this problem and I am from Iran. My mobile ROM is the global version. It seems that this problem is caused by the Poco F3 mobile hardware itself. If anyone finds a solution, please let me know, thanks.

Question no internet connection when switching from 3G to 4G

hello everyone, im having an issue on my poco f3 it happens on both miui official, eu v13 & 14
like title says, whenever switching from 3g to 4g there is no internet connection and i have to turn airplane mode on and off for it to work again...
you can trigger this issue by going to settings and manually changing to 3g and then back to 4g, but it can also happen automatically if the signal is low...
does anyone else experience this issue? is there any fix for this?

3 possible reasons:
1) When youre using 3g, your phone is connected to the best signal 3g tower nearby, switching to 4g makes your phone use the same tower (could be a low signal 4g). When you turn airplane mode on and off, the phone connects to the best signal 4g tower nearby.
2) Faulty SIM card
3) Phone faulty hardware

Thank you for your comment.
I dont think the SIM is faulty simply because when i insert it to my redmi note 9s, this issue does not exist.
does your poco dont behave like this?
