After using the device for a month, I am experiencing sudden network fluctuations. The device latches on to the network and very next moment the bars disappear. There had been very few days( 2 or 3) when there were no signal issues, full bars. However, next morning I get a cross over cellular strength area with no bars.
Signal strength is good in my area and there is no outage. I have swapped SIM cards both on and from this device, it cannot connect to network. Changing preferred network type also didn't help me.
Is there any way to solve this issue?
Thanks!
I think, as long as your sim card is fine, this is another proof of bad code quality. For me it sometimes says "no sim card" and only a reboot fixes this.

SIM card seems fine! For me, it says "no service" and somedays, around evening its full signal and the next morning it shows a cross sign. I have verified with few of my colleagues who use Mi A2 with the same carriers, it works like a charm for them! I did a factory reset yet this erratic cellular reception still bugs me! Can this be fixed with October Security Patch?

Other Xiaomi devices also had similar problems and only custom roms helped. So you unfortunately have to wait and see.

I'm running the stock 4.4.4 ROM on my Moto G 2014 Dual Sim XT1068 Titan. I have a Sainsbury's SIM in SIM1 and a Three SIM in SIM2, which is also the data SIM.
I don't get very good reception in my flat on Three, so often when I move from room to room, I lose the signal completely but this causes a notification to appear saying that I've lost signal on the Sainsbury's SIM, even though that's showing full bars at the time. Even when I get signal back on the Three SIM, the notification doesn't go away and the only way to get rid of it is to tap it, which then opens the Mobile Network selection screen and takes ages to scan for networks before I can select one and close the screen.
Has anyone made a patch that fixes this annoying bug, ideally to make it not show any notification at all when the signal is lost, so that it can just resume silently when it's found again?
No-one else having this problem? I lose reception on my Three SIM2 at various points in my flat and get this annoying message incorrectly telling me that my Sainsbury's SIM1 has lost reception. I also often find that when the Sainsbury's SIM does lose reception, it won't automatically start working again when I get back within range of a signal and it says with the red cross/triangle showing.
At least I found a quicker way to get rid of it is to go to the Dual-SIM settings and disable/re-enable whichever SIM has lost signal.
I was thinking of finally updating to Lollipop to see if that fixes the problem. Does anyone know if it does or not?

Thanks, I'll have to try updating then. In fact I already did but the update failed and it rebooted about 1/3rd of the way through, so I guess I'll have to completely wipe it and flash a Lollipop ROM.

Welcome to the Nexus 6's absolutely horrible reception. This phone has got to be the worst phone for reception.
Let me guess it bounced back and forth between H+, H, 3G, 4G, LTE, and "!". I've been dealing with it for several months now. T-Mobile has even warranty replaced my Nexus 6 twice and still not better. I keep telling them its not the phone its a software issue. That I believe has something to do with Project fi. Seems as if the software to run project fi is causing the phone to gain then lose signal over and over. It's like its trying to jump to the best possible tower for better reception , like Project fi does.
All I know is Google and moto need to get their act together and address this issue. There are way to many complaints on this issue but no one seems to care about speaking up on the issue much less fix it.
Thanks for your reply, I will try to change new sim card,because this problem I have it and on nexus 5 with micro sim,but I cut my micro to nano sim,but today i got new nano sim,and hope the problem will solve
Hi MI5 community,
I am unable to use mobile network flawlessly in my MI5. Sometimes SIM1 running, SIM1+SIM2 both running, none of SIM card works. 2 weeks back I mistakenly selected the radio band as USA Band from *#*#4636#*#* -> Phone information1. Then after a fresh flashboot ROM installed problem solved automatically, but ideally this should not be. But now I am having terrible issue with SIM1 and SIM2 signal reception. Finally I have successfully write NV Values which was originally. But even after setting up values to the original, I am not getting mobile network signal. If I put only one SIM card then status bar says No Signal. If I put both SIM then 1st one says No Signal and 2nd one says Emergency calls only. Sometimes randomly SIM1 runs but SIM2 not. sometimes both not, sometimes both. Frustrating experience ever. Would appreciate if anyone can help me.
Looking forward some help from @TheUltrametricSpace especially.
I don't know whether i can help or not but i used to have mobile network fluctuating issue. At the same area, my SIM1 AND 2 will goes from 5 bar to 0, then came back to 3, then back to 0 then back to 5 again. It happen countless of times during the day(or even night). But the problem fixed when i switched to xiaomi.eu rom for mi5. I did do clean wipe system, data via twrp before i switched to xiaomi.eu rom.
Hope that helped
Hi @yChoon
Thanks for adding some views. Yesterday full day I was in latest EU ROM and the whole day I couldn't able to receive any signal. But around 8PM I have received signal @sim1 only. I hope I will be able to find out the culprit someday. But completely clueless

Hello @yChoon
I'm having the same issue as you with my Mi5. Did you ever experienced those issues again?
Hello. About a 4 months ago i have bought from eBay a note 5 at&t version. I live in Greece and my network operator is WIND GR. The phone works fine but from time to time i get an emergency calls only message. And i can't get and do a phone call. If i restart the phone everything goes to normal. Sometimes it goes on and off by itself (the problem).
Have been anyone experiencing the same issue? If the phone is incompatible with my network operator should it not work at all?
Did you tried to change the sim card? Maybe issue is from sim or from sim slot

My sim is new. When i purchased the phone i have changed my old sim with a new sim 4g compatible.
It happened again. And i am missing calls like this. I will smash it with a hammer
Go to settings, backup and reset, then reset only network settings, see if any better signal

Done that right now. Tomorrow i will get a new sim card and i will post if anything gets better. Thanks for the help.
Update of the situation. I have changed sim card 2 times. It still happening. My phone runs at nougat now and the problem still appears as before at 5 and 6 Android version. I currently gonna change service provider that has better and stronger signal. From what i have discovered. When the phone looses signal due too poor service provider signal sometimes it can't register to network by itself. If i enable airplane mode and then turn it off it comes back. Any clue? If it's hardware issue what can i change?
Should i have at the mobile networks auto detect or manual and my carrier?
I wanted to see if anyone else had issues with their signal for tmobile and after updating to android 9. I am running into an issue where for a few days I would have LTE 4G signal but at some point, I would lose signal completely. This issue persists once every one to two weeks. Here are the steps I did to see if it would resolve the issue:
- Reset Network Settings
- Reconfigured the date & time so it would be the correct time and date and timezone
- Removed automatic set date and time
- Did both a soft and hard reset
- Cleaned out system cache
- Booted into safe mode
- Checked the service hidden menu and ran tests and all came out pass
- Reset Access Point Names
- Ran Search Networks in Network Operators Menu and failed
- Ran Select Automatically in Network Operators Menu and failed
This issue has been annoying ever since I updated to Android 9. If anyone has a solution please advise. My phone is not rooted and is stocked image.
I'm on Tmo and received the pie update some months ago. I haven't had any issues with signal strength since. I'm racking my brain trying to come up with some advice but wow you have some everything I can think of. How about trying a new SIM card?

I actually did replace the SIM card. Here is the weird thing... When I removed my sim card, I would get the icon showing that there is no sim card inserted so of course no signal was showing. After inserting the new sim card, the phone would see and recognize the sim card but still no signal bars would be showing.

Download this app, "LTE Discovery" https://play.google.com/store/apps/details?id=net.simplyadvanced.ltediscovery
There's a feature that logs your LTE data, wait till you lose signal again and then review the logs.
