Hello,
I'm losing my wits, hope you can help me..
My G2 mini (new) worked flawlessly for a couple of weeks, then suddenly lost all network signal. After a few days, thinking it was a software issue, i unlocked the bootloader, rooted the phone, and installed CM11. An hour later - full GSM signal. For a few hours.. Since then, i've been having random x hours with, y hours without GSM signal, with absolutely no reason for the changes (phone laying on the table, absolutely no user input).
It might very well be a hardware issue, but my google-fu failed me big time, all i seem to find are GPS issues (which is not the case here, especially since i don't need GPS on this particular device).
Here's a breakdown:
- The phone originally worked with no signal loss (original OS)
- Unlocked bootloader, rooted, installed CM11
- Signal works for a few hours every day (random pattern), loses it just as miraculously.
- Device finds no networks when using the in-built search functions, but i receive no error message. When using Automatic registration, the phone displays: "Can't connect to this network right now. Try again later".
- My SIM card works fine in my D802, same issues occur on the D620 with a different SIM card (which also works without fault in the D802), so it's definitely a phone issue.
Questions: Anyone have any idea what's going on? Could it be a baseband flaw? Is there a way to (re)install the baseband, to eliminate any possible software issues?
I have disassembled the case, and all pins have wear marks embedded, which means there's plenty of contact, as far as i can see.
Thanks in advance, guys!

Unfortunately, my issue seems much more severe. Toggling the airplane mode, restarting the phone, nothing seems to work. It just regains the signal whenever it feels like it. For instance, it's been "off" for a few days now, with the exception of 2-3 hours a couple of days ago.
Thanks for your input, though!

With the latest release the problem disappeared. With previous releases I would open the phone sometimes and it wouldn't have any signal. I either had to restart it or toggle airplane mode on and off....

I have a problem with LG Optimus One 10Vn
From time to time it loses signal completly and won't come back only if i reboot the phone.
I've restored to factory but it didn't solved the problem
And i'm not the only one with this problem a colleague has the same problem
No service
Hallo,
I also struggled with this problem. From time to time the phone lost the connection to the german provider T-Mobile. Seems to be a problem with some Micro-SIMS.
I upgraded the firmware vom V10A to V10C, which cured the problem for me so far!
Regards
Hans
I have the latest FW V10N
i have the same firmware and no problems so far ... installed it about 4 days ago , data connection works fine connected 24 / 7 no signal problems at all .
This happens only if i loose the signal then it won't come back only if i reboot the phone
I also encountered this issue a couple of times a few weeks ago, hasn't happened since, to get service back i just turned airplane mode on and off. Don't really know what made it stop. (Vodafone Romania)
If it still does that try a hard reset and if it doesn't work go to vodafone and tell them to exchange it @ warranty ... Dar sa fii mai cu tupeu ca romanii nostri sunt nesimtiti la garantii

i did try with the airplane mode but it doesn't work
and i did the hard reset part like 3 times already
it i'll get that error again i'm going to warranty to get another one
Had the same problem. Phone was working fine, came back one day to find it shut off and [no service]. Nothing worked, airplane mode, complete wipe.. nothing.
I was about to return it when I tried one last thing..
Wifi and Networks->Mobile network settings->Network Operators->Search networks
fixed it.
Hmm then it seems like an OS bug. If the signal drops it won't search for it again
What nerwork are you on ? It's weird i never had this problem ...

I'm having the same problem.
sometimes it looses signal and won't come back until rebooting.
Turning plane mode on/off won't solve the problem. Neither searching for networks like some one said. It finds all carriers available but won't connect to any of them. Only rebooting gets signal again, which is a bit frustrating.
My fw is v10a... I think this is the last one available in my country

What's about SIM card? Do you have it long? I heard about some problems, if somebody had too old SIM card.

I have searched Google but this problem seems to be unique to my sgs2.
I got my sgs2 from UK a week back. Its O2 branded with latest official firmware (2.3.3 and XXKE7), that's what see from phone info. I am using it on 2g network in Pakistan. The mobile works fine and connected to mobile network quickly after 1st boot. But after sometime, when i woke it up from sleep mode, it had lost mobile network connection and went to emergency calls only. This is continuing to happen everyday. I have noticed that it usually happens when the phone is turned on from prolonged sleep, esp in the morning when i wake it up. The network signals show full strength and it also searches all networks available but when i select my network it says , unable to connect try later. The only resolution is that i have to reboot the phone and it automatically selects the network. however that too doesn't work always and i have to reboot several time. Somebody suggested to kill Dialer and reconnect but it didn't help either.
Please help!!!

First update phone to newer version.
Second it might be a sim card problem. Especially if it is a very old card. Try with a newer card.
Report back.

JJE/Mario: Guys I have come back after a while since It took me longer to flash the ROM. I have updated it with XXKG5 ROM that I found on Intertech post, but to my astonishment, my problem remains the same. Phone stays on "emergency call only" after wake up or when I move few miles from my place. Sometimes it stays on this mode throughout the day. Strangely, GPRS/Edge works, however I do not see the 2 arrows radio symbol in notification area.
Is my phone damned or there is any hope?
Same problem..

that worked for me, but the problem had nothing to do with the imei number, if you look carefully. Also I think This is just temporary and it's going to revert back to emergency calls only. I'll let you know when that happens again
I was on the phone with my girlfriend, when suddenly my device rebooted. I attempted to call her again, but it rebooted again even before the call screen loaded. Afterwards, my phone endlessly rebooted when it finds signal. I tried re-flashing with Flashtool, but it didn't work. Apparently, this occurs when it is on GSM mode. Is there anyone who knows how to fix this?
NOTES:
My bootloader is unlocked (warranty void)
SIM card works fine on other phones
UPDATE
Everything is fine on WCDMA mode, but when 3G signal is lost and it reverts back to 2G, the bootloop happens again.

May be the issue with the your Network IC. Cause I faced a similar situation. When the Airplane mode is enabled, Phone works fine. But When it is disabled, the phone reboots.
Not sure this issue is related to you or not. Just a suggestion :good:

Well, damn. Everything just got worse - it reboots even when on airplane mode. It happened while I was playing Minecraft. Now, the phone reboots every time, regardless of signal or anything. I guess I had better replace my beloved phone. :crying:
Did you try to reflash stock firmwire with flashtool or maybe a custom Rom? That usually solves things....

I have a problem with my Galaxy s6 Edge.
When browsing the web with only mobile data turned on, wether using edge/3g/lte, the mobile loses connection .
I still have connection visible in the status bar, but wepages stop recieving data and it just stays hanging, with the loading bar at the same place. It can be fine for 3-4 minutes and then start to act up again.
One sollution is to toggle data connection on/off, then it will work again, but only for a couple of minutes. My phone is unrooted. I have tried factory reset. I have tried using the different settings in mobile data; just gsm7just wcdma and wcdma/gsm- automatic etc. The signal strenght seem to be about 75-77dbma.
Do anyone have the same problem, know of a cause for this, or have possible a sollution? Please share
I've had a similar issue a few times now. No discernable cause. Solved by airplane mode toggle.

Yes, I will try that, but think thats about the same effect as toogling data. It helps, but the problem is still there. I sent an mail to Samsung about this issue. Hope it is software related and can be fixed. Its frustrating cause I`m reliant on stable data connection. When logging in again, the webpage has changed and i`ve lost my opportunity.

I have the same issue, and connection drop even if u you are in thetering mode(wifi/usb)
I got new mobile (replaced from vendor) and the new one have similar issue.
I try on lte/wcdma - only wcdma, with one apn and so on.... nothing to do problem is still there...
Sorry to hear that! Its a shame paying this much money and find out about these problems. This phone replaced my s4 because of the "sim card not detected-restart" error on the s4. First Samsung denied the issue. When they admitted it, I had already opened it up and exchanged the sim card reader, and lost warranty. That was not the fix.
Hope the issue will be fixed with updates. Lesson learned- Dont buy first batch of mobiles. Wait for prices to go down, and a more mature hardware.

I have the exact same issue on my s6. I can't figure out why it happens. It appears and disappears for no obvious reason. I wouldn't mind waiting for a software update to solve the problem but I can't stop wondering if I have a defective unit.
I' starting to wonder if there are network changes on the phobecausing this. The signal keeps going from H to H+. And maybe the adapter has to reset before it can download again. Just a hunch, but I have noe knowledge about what's happening.
But, if this was a widespread problem, I think more people would come forward saying they have this issue. If they don't have it, then maybe we got bad lemons, and we have too keep exchanging til we find one that works.
Its an software problem ( i guess of managing "swap" between h h+ and LTE. after 7 day of test i got the mobile replaced from mediaworld, and the new one have the same issue.
Im from italy with Vodafone, maybe all of us are vodafone.
can be interesting discover from where we are and our mobile company.

I'm using "Telenor" here in Norway. They have a 1 month deal with Samsung to be the only supplier of the edge. Tried to get internet/mms setup sent from them, but it said this wasn't available for this phone. But going to their guide, it seems everything I set up as it should.
I tried switching on the data roaming. That seems to solve the issue so far. I haven't had to switch the data on and off for more than 24 hours now. Before this I had to do it multiple times every day. I guess it's safe to say that the problem came from the software side. Let's hope that fix it in the next update. I'm using international version, though.

I just turned on the data roaming, but still on the same service. Now I can't really tell if that really did the trick. I got new firmware update just the day before yesterday and now the network drop is gone. If you haven't got any update yet maybe you just gotta wait. It's eventually fixed.

I've got the same issue. Only airplane mode on and off helped me. But I've to do it many times during the day. I wrote a letter to Samsung and waiting their response.
Just read about roaming "on" as one of the users mentioned here, still testing.
PS I'm from Russia (on local forum many people has this problem). Hope this is software problem.

I am from Canada i have same issue plus my phone does not even have lte/gsm/wcdma option but still when i go on the *#2263# menu and put my phone to lte/wcdma it looses connection in like 5 minutes.
but still if i am connected to the internet same issue connection stops and it starts woking after a minute or so but really really frustating specially with a price tag on this phone.

Solution: Disable "Dual 4G" option in the "SIM Cards & Mobile networks" settings
Hello, good day!
tl;dr: Phone stuck to no cellular signal, until I reboot, restart mobile radio power, or turning on airplane mode for a short while when turning off again.
---------------------------------------------------
I recently bought this phone as an upgrade to my old one. I transferred my sim, and all seems to be working pretty well. I lived in an area with very poor signal reception, so overnight, the phone doesn't have any signal reception other than WiFi.
The problem is that it remains that way (stuck on 'no signal') if it cannot get any signal for an extended period. The problem persists even if I went to an area with good cellular reception even in the city.
The problem seems to fix itself when I placed the phone either by activating airplane mode for a minute, turn off "mobile radio power" then back on again, or reboot my phone but it starts to get annoying over time.
I tried changing the preferred network type to the one my old phone used (LTE/CDMA auto (PRL)) to fix it, but no luck.
Does anyone know a permanent solution to this?

I tried the SIM Reset first and so far it is working perfectly but I need to monitor it first to check if the problem would persist in the long term.
Will update thread on the result.
================
Update: unfortunately, the SIM reset doesn't work. However, I tried swapping the SIM card to see if it makes any difference and surprisingly it did. I put in a SIM in slot 1 from a network with a good signal reception while my previous one on slot 2.
I would like to also note that the current SIM 1 has a successful Xiaomi activation & verified to use the chat features on the Messaging app while the old one does not.
All seems to work perfectly - but need further monitoring I can call it solved. Will update the thread on the result :good:
Update 2: The workaround above doesn't work. I sent to Xiaomi this issue.

My sim is in slot 1. still dropped calls. Seems like network disconnects and reconnects.
When call is dropped I immediately redial and sometimes no network.

Unfortunately, the workaround I posted doesn't seem to work also when my current SIM 1 can't pickup signal for at least 2-3 hours.
Yes I also experienced drop calls most notably when the signal drops below 0 bars (not no signal with an "X").
I can't find a good rationale a factory reset would solve the problem since nothing on my phone (modified settings, modded, or downloaded apps) that can affect the cellular network. So, I won't be taking that road for now.
I already sent feedback on Xiaomi and advice me to send the log files *fingers crossed*
Any updates..?
My father is experiencing similar experience with calls hang and even bad call quality, while pocophone f1 on the same network works flawlessly.
Data problem
I have a problem with my RedMi Note 9 Pro, when I make a call on 4G Airtel network(at least 4 bars) the data connection drops to an average g of 1.2kbps.
I have used the same Sim in the same area in my previous phone the Honor 9 Lite but it doesn't face any problem. Whenever I get a call on that phone the 4G data speed increases.
On the RedMi note 9 pro the data gets completely disconnected and even after I cut the call the data remains disconnected for 2 minutes or so. After that I resumes back. It even gets lesser speeds that my previous phone.
Sometimes the data drops without any reason. It stays disconnected for a minute or so and then tries to connect back. It has got horrible ping.
Anyone facing the same issues?
Having the same issue here. I modified phone settings several times and try with another apps but nothing working so far
I MAY HAVE FINALLY FIGURED OUT A POSSIBLE SOLUTION!
Disable "Dual 4G" option in the settings.
No issue so far for 3 days now
