Hello guys, my phone fails to connect to the Internet under a specific circumstance even though it receives 5-bar HSPA signal. This problem is a bit tricky to reproduce. First, I'd like to say that it's a 4G plan and my phone IS ABLE to receive 4G signal and has connection to the Internet wheb no problem occurs. When I go to some places that my phone receives 2-bar signal only (e.g. in Elevator, tunnel, etc.), it'll drop to HSPA with 2 or 3-bar signal. It seems normal, right? But then I go to somewhere that's supposed to have 5-bar signal or even has a clear blue sky above, my phone receives 5-bar HSPA signal with NO connection at all! Here I say No connection instead of no Internet connection is that it can't even receive or make any call when the problem occurs. The phone will obtain 4G signal again only after turning off and on mobile network or Airplane mode. Otherwise, it just sticks to this status forever. Or if I wait for an enough time, which varies from a few minutes to half an hour, it'll eventually have an X on the signal bar and reset the connection to work again. This problem's already driven me crazy! May someone help me please:crying:
I have an S-off unlocked HTC_622 HK version device (was changed to superCID recently). It went through every version of firmware from 1.80.708.X to 2.28.401.9 and both HK stock ROM and LeeDroid ROM.
Edit: It also happens sometimes when it connects to 4G.
I have used an unlocked HTC 10 with T-Mobile service and haven't had this issue, but I had similar issue when on WiFi.

No, never dropped it. It's been like this for a long time. I thought that was because of faulty SIM card at first, but it turns out the SIM card has nothing to do with the problem.
Send it to service then. It may could be a hardware issue
if you reset everything back to original does it still have the same issues? If so then probably a rma request is needed

I consider doing it all the time since it's happened. Last time I called for a RMA because of touchscreen unresponsiveness along with signal issue. They just replaced the screen and did nothing with this issue. What concerns me most is the phone looks and behaves like 120% "normal" as long as it doesn't undergo the "specific circumstance" I mentioned. Looks like I need to state very very clearly about the problem this time.

At some point, I'd been using stock HK ROM and kernel for a week or two with root only. It still had the same issue.
Hi
I have quite the same issue as you with my phone except it is with 4G. I explain, some time I can have a full 4G strengh (4 bar signal) and still cannot access internet, or send SMS. It seems that my phone can send data but not receive because I'm able to make a call, but not receive one. Also people receive several time my SMS : they still appears as sending in my app and I believe their are sent but my phone seems it doesn't receive any confirmation, so it still try to send it.
If I go back to 2G/3G mode in network, everything works fine. This would be easy if 4G never works, but sometime it does so this looks like a random behavior.
I think this is a 4G band issue. I found an app called LTE Discovery that display information about your network. My phone works correctly when I'm connected to band 3 and 20 (can see the exact frequency in the app). My carrier (SFR, in France) uses also band 7 and 28, but I still need to confirm those bands work or not (seems band 7 works but not sure, this might be specific frequencies of this band that fail).
And when my phone does not work, the app fail to display the exact frequency I'm using.
I have an unlocked boot loader, Venom rom 4.2 (Android 7) and an old firmware (1.80.xxx). Issue started to shwo when I was using Marshmallow, and a full wipe and rom reinstallation didn't fix it.
Does it looks like your issue?

It really looks like for the part of 4G connection. AFAIK LTE doesn't handle phone call and SMS? Have you tried to test with other SIM cards and phones?
I also use LTE Discovery to test my phone. My carrier uses LTE band 3, 7, 8. My phone does receive signal of all these bands and works fine with band 3, 7 even with 1-bar signal. But for band 8, nothing about Internet works normally except for phone calling.
Seems my last resort will be switching my phone with my friend's (also HTC 10) to test with this problem.
Hi,
It seems I managed to solve my issue. For the moment I have working LTE at home, will try at works tommorow.
I simply update my firmware to 1.95.401 (was on 1.80.xxx) and it seems to works so far.
Maybe reflashing your firmware (if it is possible) could correct the issue?

I think you'll be "pleased" to know you're not alone:
I have the exact same issue, SFR , HTC 10, Venon rom 4.2.
I had a couple of exchanges with carrier support, always the same answer: our antenna is under repair...
The only way out on my side is to stay in 3G most of the time and then I can receive SMS, otherwise, no 4g in specific places, and very late SMS reception (I can receive SMS from 2 days prior... This happen when on 4g).
By the way, SFR made me get a 10€ discount every month when I told them I would leave, you can ask for it too.

I've been on 2.28.401.xxx since a couple of weeks, I've got the issue, so maybe it's more related to a clean install?
I'll switch to 2.38.617.xxx and see where it goes
Does it appears your phone have a good connectivity when you are in 4G? I mean, my phone used to display all network bar and LTE logo but nothing seems to works.
Also, you can keep in mind that is the 4G only fail in some area, this is probably a software issue, not hardware. I also saw there was antenna repair in my area, but I was the only one to get issue. Can you compare with your mates if they also have network issue (same carrier, try to switch SIM) ?
What is your CID? Mine is HTC_034 and I couldn't install 2.xx firmware.
For me, the issue just happened, with no explaination. I didn't update firmware or install any new ROM. So yes install the new one might correct the issue for you too, if the symptoms are the same.

COnnectivity was at the max, and no traffic at all, no up or download, and no ping. That's what puzzled me.

That's something I've planned to do. A bit complicated thought, I listen to music when I commute and these loss of 4g connectivity happens in places I would not stop normally...
That's one of the places I've identified, maybe you'd know this place (I doubt but how knows...)

Not sure of this, I checked using the network monitor in the notification bar. Up arrow were appearing but not down arrow so I assume my phone could upload but not download.
Didn't check out you place specifically, but this 2 ones for sure did not works :

Didn't buy it from SFR either, but changing CID require to be S-OFF so I assume you have the orginal one. Don't understand why there is several CID with different firmware update, for WW/US version I can but for 2 phone both buy in France, not from the carrier...
Anyway, I thought this could be linked to a specific CID and matching firmware but it doesn't obviously.
I'll try the Brancion spot later today.
Something else I was thinking about, I wonder if baseband got updated , by now I have [email protected]_41.13_F.
Something I always asked myself in fact, does Radio gets updates in Viper or any other Rom do, and if no, how to.
I guess via RUU, but for now, I can't make it to work, I have to sort out how I did before
If I'm correct radio is contained in the firmware image, and will be updated with it.
You also can flash radio if you are S-OFF.
ROM won't update neither firmware or radio.
FYI I have [email protected]_59.06_F, which seems to be more recent than yours, this may be the source of the issue (no idea what version I had previously).
I used this tools to update firmware, as I am S-ON :

I've did the tests with the new radio, the phone now switches to HSDPA or 3g depending on network condition, so it sort of fixed the issue of being stuck in 4g without actual data transfert ability

I'm using the latest Zui 2.5.104 ST since last two months, everything is stock and I haven't faced any random reboot issue. May be issue was there with first/earlier version, but no issue with the latest update. VoLTE also works perfectly and never drops (Just that "HD" sign grts vanished sometimes, but VoLTE still works). You can go ahead and buy this phone. Btw, issues like random reboots, heating can be due to individual usage, so make sure you don't overheat the phone, or use bad apps.

No such issue after update
To be on the safe side just factory reset the phone few times after update....it helps to get rid of such issues.
On 2.5.104 ST, every time I unlocked my phone, screen flickered and all radios disconnected. Sometimes it would immediately freeze, go to black screen, then LED lit up, requiring me to hold power button down to reboot the phone. Sometimes this happened, but not immediately. Sometimes radios would recover and phone would continue to function. Sometimes cellular radios recovered, but wifi did not, and even toggling airplane mode didn't fix it so I had to reboot. Nougat was quite a mess on my phone and that's even after factory reset many times. Several on zukfans.eu site had similar issues.
I don't think it was a hardware issue, because downgrade to 2.0.133 ST (Marshmallow) works perfectly.

Hello everyone i'm new here, some time ago i have updated my tablet's android version from 4.3 to 4.4.2 through ota update, after about one month later my tablet started having a weird wifi problem (i don't know if it is related to ota update or not) my tablet shows good wifi signal but it wont connect (it connects only when it is near router's antenna though and this is really weird) and no it is not a router problem because it is the same problem everywhere, i tried EVERYTHING to fix this problem (wifi fixer apps, factory reset, reinstalled android firmware with samsung kies, rooted my tablet and even installed a custom rom) but none of these methods didn't solve the problem.
Does anyone knows how to fix this problem? did i miss something??? could it be a bad kernel? or maybe a bad configuration that should be changed manually, or is it just a hardware problem?
Did you try with stock Lollipop firmware?

Hi. At the start of December, I upgraded my Mi A2 Lite to Android 9 and ever since then I have been facing issues with a few apps over WiFi. The following apps are being affected:
- YouTube
- Twitter
- Facebook
- WhatsApp
- Chrome
*These issues are only on my WiFi. On 4G or any other WiFi these issues don't happen*
The issue with Facebook and Twitter is the same. Both won't load any new feed and behave as if my WiFi is not turned on. YouTube only works at times, other times it would just keep loading and nothing would happen. Sending images or videos on WhatsApp is impossible now. It even has troubles making the backup to Google Drive on my WiFi. As for Chrome the issue is that sometimes even though WiFi is turned on, it would not load any page and just say that I'm not connected to internet. I've been reading other people's threads online and even emailed Xiaomi and Google. I tried the steps (hardware test etc) as told in the email by Xiaomi but that has not helped. Some said that using WiFi and Bluetooth at the same time caused this issue but I have used WiFi with bluetooth turned off yet the issue is still there. Now if this was a WiFi issue then I would have contacted my provider but with the same WiFi connection I have not faced a single issue on any other mobile devices and laptops. As for my WiFi I can't seem to change it from ipv6 to ipv4 (or I just don't know how to). If anybody has faced this issue and knows how to solve it then please help, It would be greatly appreciated. Thank you for your time.
Have you tried disabling Bluetooth and then reconnecting to the WiFi in question? Having both enabled at the same time causes WiFi speed transfers to be really bad, it's an already reported Pie bug.
Btw, can u see 5ghz wifi networks?
Cause i can and have same problem with slow wifi+bluetooth
Yes I have turned Bluetooth off and used WiFi like that but the issue is still there with all the apps mentioned
Any update on this? I'm having the same issue. Using a VPN seems to solve the problem but the connection is slower.
I am facing the same problem on my A2 lite Android One Pie. Even the further upgrades including March upgrade did not resolve the issue. It really sucks.
Has anyone found any solution?
Is MI even concerned or acknowledges the issue?
Is there a way to go back to Android 8?

Hello Dear Sajid Abid,
Good Day !
1st Remember One Thing. Downgrade Is Not A Easy Task, Downgrading Has Also A SIM Issue Problem,.But If You Still Want To Go Back Your Mobile Device From Pie To Oreo You Need To Unlock The Boot-Loader (Off-Course Unlocking Boot-Loader Will Void Warranty) Then Download Stock Oreo (From MIUI Forum) And Flash It With The Help Of IMFlash Tool. After Successfully Ported The Stock Oreo Rom You Can Close The Boot-Loader.
All Instructions/Steps Can Be Easily Found On A2 Lite Forum.
Here Is The Link Which Can Help For Resolving SIM Issue Problem.
https://forum.xda-developers.com/mi-a2-lite/help/sim-card-issue-downgrading-pie-9-0-t3874350

Hi,
I own a Xiaomi 11 Lite 5G NE. I have updated to the latest MIUI Official V12.5.8.0.RKOEUXM.
From the beginning, I'm facing the issue that mobile data is not working. You're navigating and suddenly all stop and finally it shows the error no network.
After restarting is working fine again but it's very annoying. I've been looking for help but nothing found has helped.
Is anyone else facing this issue?
Thanks for your help and time!

Hey. There
For some Days I also having mobile data problems. My phone så browser says No internet connection..
When i turn phone off or disable mobile data off for 30 min IT Works for a short period, then IT stopps again. I can use Wi-Fi at home.
I have factory restored my Device but its didnt helped. Swiched to second sim slot and nothing..
Gould be cool od someone knew how to fix it. Or need to send it in. Had this phone 3 months .
Specs..
Xiaomi 11 Lite 5G NE
MIUI 12.5.7.0 stable
Model 2109119DG
Same problem here. I'll preface this by saying that I work in a place where the reception isn't great, but with my old Huwaei it never happened.
When I lock the smartphone and then unlock it after a while it shows 4G+ but in reality there is no connection.
Last night at the gym (in a basement where the reception is zero) after I left it wouldn't pick up the network again.
To solve it I have to put on and take off the airplane mode.... Very very frustrating.
I also replaced the sim card with a new one but no dice.
MIUI 13.0.5.0 Stable
Thanks all for the replies.
So I'm not alone, but it looks that some people have not issues.
Looks also problem is on MIUI 12.5 and also on MIUI 13.
I think it is a hardware problem, not software.
In these days Ill take it in assistance and I will update you.
Unfortunately, it has been too many days since my purchase and I can no longer return it. Super regretful that I didn't get a samsung a52s!
Need to that we had igły weather here with lightnings and storm . Many trees was Tilted.
But checked mobile operatora site and nothing there.

They should have write something on their homepage. Will have helped , so I didnt had to factory reset.
That's All for now.. Have nice weekend you All.
Hope you will have yours problem fixet.
Bye
I also had major issues with my mobile network on 1 of the simcards. (I am using dual sim)
If your provider supports 5g then call with the dialer *#*#4636#*#*
you will see a menu with 3 options. the first selection is simcard 1 the second simcard 2.
change the prefered network type to NR / LTE / GSM /WCDMA or whaterver ur provider is supporting, NR = 5G network.
Make sure you disable VoLTE for both the sim cards since this was disabling my download from mobile networks.
hi guys, yesterday I took my cell phone out of repair. They replaced the motherboard and now it seems to be working fine, no signal loss.

Hi Raulci, i replied u in the other thread!
Just wanted to let you know that during the last weeks, I haven't experienced any other mobile data issue again. I have changed anything. Let's see if it continues this way.
Yes its a problem. Initially i thought its miui 13 problem. But reading above comments with slow speed/ 4g connectivity issues in 12.5 it seems its hardware related. Inferior modem or low quality antennas could be the case. I was hoping to fix by reverting to 12.5.
Same problem i have mi 11 x i even go to the service centre they factory restart my device and it's not fixed they said it must bu hardware problem
