Received my SGS2 on 29th June and ever since it start having emergency call syndrome (out of blue not receiving any network signal).only after reset, it regain signal and same story goes on till date.
To overcome this prob,i tried these:
- factory reset 3 times
- manually choose telco/network carrier
- update/flash firmware (stock XWKF1 -> XWKF3)
so for these only reduce problem's rate to occur.PLease,help anyone?
Is your sim card active ?
Hi
I have the same problem as yours (i thought i am the only one having this)...out of the blue the phone changes to the emergency calls Only status....
it is very annoying specially when you are expecting an important phone call and you discover that the phone cannot receive calls
it became a habit of mine to keep checking my phone every once and a while, and when spotted i restart my phone and this brings the phone back to normal (Normal for a day or two of course).
Can anybody help with this?
SGS2 GT-I9100, Android: 2.3.3, Build: JHKG2
First of all I would download a newer firmware. If that doesn't fix it you should probably just return it to Samsung for replacement/repair.
Actually i have flashed this Israeli ROM (it is an Orange official but leaked ROM) about a month or so and it supports Arabic, English & Russian (exactly what i need) that i have no complains about so far except this emergency Calls issue and i am not so fund of rooting etc so i don't know where i can find another ROM (official not cooked ) that have the same languages supported.

What is your signal strength when it changes to emergency only? Mine does that during very weak signal, I found it's because it can only receive GPRS singal which is from another carrier when my own (HSPA) can't establish connection.

frankly i didn't check or notice such thing, but the moment i installed my latest ROM (GB/JHKG2) i have noticed that the signal strength is very week especially indoors.
thinking off and analyzing this situation i have a confident opinion that the problem i am facing is related to the ROM i am using (GB/JHKG2).
i am thinking of flashing a different Kernel to this ROM and see what will happen

When you installed a different rom did you flash back to your original telcos baseband? This makes an enormous difference to signal strength.

First time asking for help but I can't find the answer to my problem. I have no service on my X10, no calls, text, data. No service at all, just grey bars with a BIG X. I don't know how to tell if it's a hardware or software issue. I don't think software is the problem. I put my phone in airplane mode one night and the next morning turned back to normal mode. I noticed later I had no service. I had been running the Wolf 4.0.0 for about a month when this happened, with no problems at all. I have flashed back to 2.1 and then 2.3, no change. Searched and entered APN's for ATT. I did find some posts about "CRASHING SYSTEM SERVER" but I don't think it applies to this software. Am I missing something? I sure don't want to pay Sony $185.00 just to re-flash my X10 with a quick fix.
Any Ideas???
My setup is:
Wolf_Xperia_4.0.0

Try your simcard in a different phone to make sure the sim is working as they can sometimes die I've had a few die on me over the years without even touching the sim since it was put in the phone.

No Service Issue
I have same xperia x10i with baseband .71
it had same problem few months back and it was working fine
changing sim caused the problem again
now it wont get any signal with any working sim
Is that problem hardware related or software related
FYI i have tried stock 2.3.3 cm7mod and team rom 3.8/3.9 but no service...
Help plz
Regards,
I don't know what the problem was with my phone. It started working one day and has been fine ever since. I do know that I was using the phone in a weak signal area, 1-2 bars max, before it stopped working and when it started working again I was in a full bar area. A software glitch or antenna problem, not sure. I have 2 of these phones and side by side the network radios have completely different signal profiles. The phone I was having trouble with still gets half the signal the other one gets.
Thanks
Hello
I got my xperia z2 D6503 2 days ago brand new sealed. I inserted my Net10 sim and it worked like 1 day and than I noticed that there was signal issue first I thought it was because of area than I found out it was phones fault since same sim card worked perfectly on my old xperia z and also on xperia z2 Tab and on my brothers galaxy s4. strange thing is it shows low signal only when LTE is on and I can send and receive text messages but I can't make calls. as soon as I turn off LTE it looses signal and no text or call go through.
I tried factory reset, 2 different sim cards, even bought new sim card, numerous restarts and nothing helps. searched web for this issue and nothing at all.
so anyone else had this experienced? any solutions?
thanks

Same issue with my z2... only when I hold it a certain way... I'm on Bell mobility in Canada and got the phone a few days ago.
I've been experiencing the same issue ever and I've had my phone over a month, I'm on EE in the uk running the .55 firmware. My phone is currently in repair to fix this problem so I'll get back to see if it can be fixed
Sony has no solution in USA and can't repair so I returned for exchange to seller. I though it was only me so looks like gonna be big issue

Hey, so did the exchange solve the problem for you? I am using NET10 as well and while I do get signal on all networks (2G. 3G, etc..) I notice that it isn't as good as almost any other phone I've had. I live in an area that has poor signal and places that I get 1-2 bars on other phones I get 0-1 on this phone, though when I'm in upper town where signal is great I get about the same as others do. I'm just not sure if my phone is defective or this is just how it is. I really don't want to wait to exchange plus the seller seems reluctant to do so..
I had to fix my APN (wireless &networks -> mobile data).
I Google the correct settings for my carrier(ATT/USA), and saved the updates and it worked IMMEDIATELY.
it's been solid since ever since. Note there are differences for the 3g VS LTE versions. Make sure you enter the right settings.
Good luck!

I did entered correct APN's as I mentioned it was working great for almost day and Than suddenly stopped working so if I had entered wrong APN's it wouldn't worked first time I powered it on. plus same sim card worked well on other LTE phone while was not working on my new Z2, so it was not APN issue.
Try rebooting 3-4 times and then wait. This should solve the problem.
Check the baseband version online and on your phone.
There is also a firmware update but you have to cable your phone to a computer and let it install the Sony software on the PC/MAC ... Mine updated yesterday...
Worth a shot if you haven't done so already.

Thanks man, it seems that's just how the phone is, maybe I can stop worrying so much about that now, especially since this Z2 I have has no defects that are so plentiful on other user's phones.
And like I said, it's not such a big deal when I'm in places with adequate coverage so it's tolerable. I updated to .402 yesterday and there isn't any change with signal but I'm holding out for more updates that can help out with coverage. I'm thinking once the Z2 is released in some way in the US (carrier or Sony store) that there will be an update then that may help us out.
I'm probably the last person to be offering advice in this forum, however, just a couple days ago I noticed I had no data connectivity at all. Calls and texting still worked, but no cellular data. All my APN setting were correct and even though airplane mode was not selected, turning it off and on again got my data connection back. Just something stumbled upon and I have no idea if it applies to anyone elses issue here. Just thought I'd toss it out there in case it helps just one person.

Solve which problem? The one i posted in very first post or the weak signal on my replacement? I did more than 5 reboots to solve first proble but nope.
Now this very weak signal worries me it loosed signal at places where my old Z was great. Hope this phone doesn't end up super problematic
Sent from my SGP521
Sony Service will service/replace the set, if needed. So please do check in there.
phone is amazing everything works smooth, but weak signal is getting on my nerves! looses signal very often and data gets really slow because of low signal even when LTE is available. I live in brooklyn ny and my xperia Z didn't have this issue at all. hopefully this could be fixed soon by software update.
Drop down quick settings from home and ensure LTE is ticked on.

Same problem
My sisters got the same problem,
Help line, Tech team no help what so ever !!!
Been on the phone for over 2 weeks !!!
They wont solve the problem what so ever !
One tech team even said "buy a new phone" !! such great customer service !!
They are wanting £150 for it so it can be "fixed"..... also wanting £40 for the month contract despite not having the phone !!!
I understand who you feel... they are no use what so ever and rude...
Hello
I recently purchased this phone for a family member. We set it up yesterday, and found that the sim card from their old phone that we've inserted isn't capable of allowing the phone to make/receive texts/calls. It just says something along the lines of "Can't connect to mobile network", despite showing signal bars. When I checked the connectivity bands against the mobile network's, it appeared that the phone should at least support 2G & 3G. I'm in the UK and haven't modified the ROM.
Has anyone had this issue before, and does anyone know of a fix? I've heard that some of the newer official ROMs are better for connectivity, but I don't want to flash the phone and void its warranty if the fault lies with the phone.
Many thanks
Luke
Heyyo, hmm can you please provide more information?
Link to the exact product purchased
What country and network is being used?
Does your device say x820, x821, x822 or x829 on the back of it? If not does it say what it is in the settings > about phone menu?
Can you please specify which version of EUI ROM it is running? Should be in Settings > About Phone.
As for upgrading EUI ROM versions? That will not void warranty as long as you don't have the x829 with EUI ROM 5.8.016s.... which is what I had and x829 with 5.8.016s is garbage. So many darn problems with it and has software updates disabled even via recovery update.zip... I didn't stay on it long since LineageOS 13.0 at the time officially came to the x2 heh

This is where I ordered it from: LeTV LeEco Le Max 2 X820 5.7 inch 4GB RAM 32GB ROM Snapdragon 820 Quad core 4G Smartphone
I live in the UK and the phone's using a Tesco Mobile SIM
The device is the X820
I don't have the phone with me right now, but I believe the EUI is 18s
I wasn't aware upgrading the ROM version didn't affect the warranty, that's nice to know
Hallo,
I believe I might have the same problem with the mobile network. In my case, I am quite certain that the battery is the problem. I got the phone some weeks ago, but I assume it was laying around for quite some time, which might be not very beneficial for the battery? Anyway, the voltage should be 4.4 V after loading and as long as the voltage stays above about 4 V, I have good data connection. But after a while, the voltage drops below 4 V and I do not have any connection anymore, despite showing all signal bars! Is it possible, that you see a similar behavior with your phone? If you load it on a charger, does your data work?

I personally do not experience this but I'm 100% sure that the voltage from the battery should stay around 4V. If this happens try turning on the battery saver and dimmer your screen so you can spread the battery load. Maybe it will work idk.

You are probably right in saying that the voltage should stay around 4 V. This is probably the case for new or at least well aged batteries. However, that seems not to be the case of my battery. According to the App that reads out the voltage, it sometimes drops to values as low as 3.6 V. Sometimes, the voltage recovers a bit, but typically, not enough to enable data connection, for which I believe to need at least around 4 V to work (reliably!).

I purchased a X820 from China (TomTop.com) and the junk had an EXTREMELY LOW signal.I NEVER received network signal at home.I have to go near a cell tower to get signal,as soon i drive away from the tower (around 5 blocks)i lost signal and could not make or receive calls..Remember that the company LeEco went out of business and the phones we buy today are NOT made by LeEco but are made by many private factories in China and in reality are cheap clones.I send the junk back and purchased a X829.Now i have very good signal and connection never dropsJust return your phone is defective..Here is a video i had to send to tomtop.com in order to get a refund.

I have exactly the same problem when the phone's battery level goes around 70% (~4v).
i.e. when battery drops below 70%, the network signal shows LTE with around 3 bars but there's no network connectivity and can't make/receive phone call. But as soon as I plug in the charger, everything works perfectly! This happens on all ROMs.
I wish there is a solution for this.
same problem for me .....
Today ,
NO WAY to have working Network mobile on a Leeco LE 2 x526 with last stock rom 28s installed on it. NOW i can call on 3G but no voice ,,,,, but i can't be called. .....after restart with / without APN / searchable 3G/4G network Digi.Mobile ...signal is lost and is cost me allot of time and energy . i even lost any hope .....(coul be a hardware problem ?)

5.write lost IMEI
6.write new baseband with DFS
7.flash modems firmware (MPSS (56347 , 61295 , 66782 and 68083))
8.try other Carrier SIMS ..... same problem
9.check any carrier server service ...nope
etc (rewrite a qcn file . different APN config , twrp 3.0.2.0 ydss )
I have real problems .....i need help (maybe someone have same problem or has read more infos from so many forums )
The same problem.

I believe your phone is a X829. Someone installed the X820 firmware to sell it easier. It doesn't have Band 20 for 4G. Tesco mobile is working on O2 network and they're using Band 20 for 4G network. Despite that it should work on 3G. In my opinion you should install a custom ROM and check things there...

Hi All
I have recently purchased a Sony Xperia 1 smartphone from new and I am having problems with the signal from the phone. I'm on the three network and I'm only getting 1 bar if lucky if not no signal from areas that normally have strong signal. My last phone the Sony Xperia xz I never had any problems so I switch the sim back to my Xz premium and 3 to 4 bars so put the sim back to the Xperia 1 1 bar possible on bars. So obviously not a network problem. I have spoken to Sony who have asked me to carry out things and factory reset the phone without any luck. Has anyone had this problem or anyone have any experience with this fault?
Adam
Do you have a case on it? If yes, remove and try again. Signal strength bars are not always the true measuring stick. Go to Settings>About Phone> Sim Status and see what the readings show for both your phones in the same location
Ho! Thank you for the tip!
Just checked with my friend S10e, both with the same operator.
-109dB for the S10e, and -115dB for my xperia 1 (my workplace is like a Faraday cage so signal is really poor). The signal is 4 time weaker with the Sony. Now I know why I struggle sometimes, Xperia 1 doesn't have a really good signal reception.
Its the firmware. Android 9 worked fine and now android 10 sucks and we have huge signal drops.
No issues here with T mobile in the netherlands, i run on android 10 also and have always full bars.
Unfortunatelly the same problems. Sony support asked for factory reset, did not help. No more support. Old phone 3g coverage whole flat, Sony Xperia 1 II without 3G signal or not measurable. Horrible signal reception quality.
Yes!!! 1-2 bar? I've never had a phone with 1 bar before??? In certain places there is no signal at all??? Dumbfounded.

Somy using best ever signal antenna in mobiles but the problem is Modem Config, firmware is made for each region deferent. If you check *#*#Service#*#* then service info and then software info then check down last 2nd modem Config should be Unknown. Thats the issue, if you using Japanese firmware then maybe you will find something Jp_softbank like this but in global rom modem config will be unknown. For make it global you need some modifications in firmware which is 100% easy and you will get Volte also.

Somy using best ever signal antenna in mobiles but the problem is Modem Config, firmware is made for each region deferent. If you check *#*#Service#*#* then service info and then software info then check down last 2nd modem Config should be Unknown. Thats the issue, if you using Japanese firmware then maybe you will find something Jp_softbank like this but in global rom modem config will be unknown. For make it global you need some modifications in firmware which is 100% easy and you will get Volte also.

Hi All
I have recently purchased a Sony Xperia 1 smartphone from new and I am having problems with the signal from the phone. I'm on the three network and I'm only getting 1 bar if lucky if not no signal from areas that normally have strong signal. My last phone the Sony Xperia xz I never had any problems so I switch the sim back to my Xz premium and 3 to 4 bars so put the sim back to the Xperia 1 1 bar possible on bars. So obviously not a network problem. I have spoken to Sony who have asked me to carry out things and factory reset the phone without any luck. Has anyone had this problem or anyone have any experience with this fault?
