Hello All,
I got a strange problem here. Whenever I turn my Wifi on and lock the screen, the network connection is lost and not able to make/receive calls. Even if I turn off the Wifi, the network is lost and the only way is to restart the phone to get it normal. I have tried soft reset/hard reset and nothing works. I have not rooted the phone and its a stock one running on 2.3.4 with version V20e. Could this be an android issue or some kind of hardware failure?
Also, I am not on 3G and work on Edge (2G). Sometimes I lose my data connection also and I have restart the phone to restore the data connection too - "E" symbol on top of the phone changes to "G".

If I were you, and if the phone is still under warranty, I would send it back for a replacement. Check the IMEI before you send it and when you get it back. Another user here in XDA has said that the first time around they just do a software reset and send it back. Then you send it back again reporting the same issue and then they replace it.
Or you can try flashing a custom ROM and there's a big chance the problem will go away. But if it doesn't then you'll have to put it back in factory condition and it might not be so easy.

Hi Folks,
how in the topic, im loosing my signal at point where my signal is weak. if i lost it, i can run around to get it back to write messages or call someone. it doesnt work, because my phone say's "only Emergency calls". i wait one hour but the phone can't connect to my provider. The radio is at the moment 32.36.00.28U_4.06.00.12_7, i've already tried newer and older version of the radio img but always the same issue. From the beginning when i had the phone, it sometimes doesn't regognize my sim card, i have tried everything to get it to work (new rom or radio img) but always it fails. on the next day without any changes the phone works again with the same sim card. So now here is my question....... what the HELL can i do to bring it back to work, so it dont lose the signal in weak areas, and if the phone loses it, what shall i do to automaticly reconnect the phone automaticly to the provider. and airplane mode is no soloution for me. thanks for answer.
Have you tried another SIM card in there to see if the problem still occurs?
Sometimes the card itself needs replacing. Just a thought..!
this i havn't tried out yet, but i tried my actual sim card at the phone of my wife and it works a whole day without connection lose. I'm just thinking its a software problem maybe its the wrong radio version.
No "wrong radio version" will lose connection and fail to reconnect.
It's either your ROM or (most probably) HW problem.
You can try to wipe and install a clean ROM and see if the problem persists. If it does - use the warranty.
which rom would u suggest ? I tried CM6 / CM7 / MIUI nearly all modded roms here. The problem is to try out if the rom works i have to go out to a point where the signal ist weak, and hope for a signal lost. Sometimes it works and i get a reconnect to network and sometimes it doesn't work. in zones where the signal is strong i haven't any trouble. Did i get any problems by HTC if my phone is unlocked? I already had it gave to a repair 3 month ago with a broken usb connector and there was no trouble with warranty at unlocked phone but what is now? can they change their opinion ?
I got it. The Problem was the the Phone has to set the Network search to manual and not to automatic search. it works now for over 1 day and it seem that is now no problem with lost signal. Thanks for Help. But i just wondering why i have to chose manual network search an not automatic.
Hi Team,
I have heard lot about this forum and hope to get some gud suggestions from you guys.
I bought my Samsung Galaxy ace GT-S5830 with android 2.3.6 Gingerbread OS 6 months back but slowly I started facing few problems when my friends noticed and told me that your phone sometimes says switch off.
I also realized that sometimes even if the airtel network is there still i get an error message that mobile network not available I had to switch off the phone to get it normal.
Again people text me but it goes on pending and gets delivered after hours. I showed this problem to the service center they flashed my mobile but the problem persist I also tried changing my sim card but still all in vain. Now i am literally fed up with this phone.
Please assist me I dont know wat to do :crying:
Note: The phone is not rooted.
Thank you
err, are you sure this is because of the phone..? not the network..? because i never face any of the problems you mention..
may be you should try flashing stock rom with newest baseband for your region, find it on sammobile..

He said the service centre guys reflashed the rom. but agree that the sms thing could be network problem.
Faulty battery/pins (Switch offs)
Faulty hardware (Antenna?)
That's all I can identify.
Hi Guys !!!
Thanks for sharing your views
@demiorkan
The mobile automatically does not gets switched off but i need to do it manually as it keeps on prompting the error message "Mobile network not available" though I can see full network on my mobile.
I would really appreciate if I get any suggestions from your side.
Let me know if any more information is required.
If you dont mind you could try flashing another stock rom and see if that works out. If it did not, then it's probably a hardware problem OR the network (as mentioned). Try your SIM card on another phone as well, that should prove if there is problem with the network or not.
Mostly it might be a firmware problem. Service center might not have flashed a new firmware but simply wiped and gave back. (can't be sure on that). So I recommend on using ODIN and flash new firmware. Google is your best friend on this.
Secondly about the network, Turn on flight mode once and turn it off, you'll get the signal. You can even do some debugging by going to the testing menu (*#*#4636#*#*) and toggle the radio and the preferred connection type and stuff. But if the place where you are is such that you get low signal, then don't try any things on phone as it's ultimately the network problem. Trust Me, the place where I stay, I rarely get proper reception and Even I'm on the same network. Flight Mode trick saves the unnecessary reboot.
Hi All,
I'll start this off by saying I have an outright purchased, unlocked device, that has had all the latest Samsung updates applied.
I found a rather nasty problem with my i9305 a few weeks ago - I tried to change to WCDMA/GSM (auto) and then GSM only to test a problem i was having with MMS (problem all sorted now, this is not my question) and when I did that, I found that everytime I selected the network mode of LTE/GSM/WCDMA (Auto) the phone automatically snapped it back to GSM/WCDMA (Auto) as soon as I left the settings.
I tried restarting the phone several times and changing APNs but still the same thing occured. The only way I could find to get 4G service back was to factory reset the phone!
As you all know this can be a major hassle. Earlier this week (long after this happeend) I have rooted the phone (using the ExynosAbuse APK that Chainfire posted) but i'm waiting until i have some more time (probably next weekend) to install twirp or CWM recovery so i can backup my rom before attempting to change it again (rom backup + titanium backup = should make a factory reset a bit less painful).
I'm wondering if anyone from here has any advice for me on anything I might be able to do to fix this bug for the future. I wouldn't mind dropping back to WCDMA only sometimes. Until I get decent backups all sorted I'm too scared to try doing it again as I *really* don't want to lose 4G.
Also, if it's ok to ask 2 questions in one post, my locale keeps reverting back everytime i restart the phone - is there a way to permanently change this? That is a minor niggle compared to the major problem i have with an inability to turn 4G off without factory resetting the device though.
Please Help - how can I fix this?
Regards,
Jason
Unfortunalety i don't have much to add, but this doesn't happen to me and i change from LTE to WCDMA all the time
The locale issues seems odd too, maybe something is up with your phone?

have you tried the service menu (access from dialpad).
Just dial the following keys *#197328640#

Thanks for that - when i'm in it though, I can't see any obvious method to lock the phone to UMTS only, LTE only, etc?
Each option just allows me to run various tests or find out more about that particular radio part.
PS - I've fixed my non-sticky keyboard & locale settings using Tasker:
Profile is at Device Boot, change keyboard to swiftkey 3, and locale to English (Australia) (it's this last bit that doesn't work yet, but i've raised it in the Secure Settings plugin thread
Hi.
I have never experienced this nor heard about it. But my natural reaction would be to hard reset my phone.
I do it regulary. Once a week somtimes.
It sounds as if your phone has encounterd a unusual state.
Either return it (unrooted) or do a hard reset. Some problems is not worth digging in to.

i have a same question, what a pity..
I do not believe there is a English (Australia) so that is where that issue is coming from, unless I have completely missed looking at it somehow
For the LTE issue
It is very likely that the issue was solved after the first factory reset so you should have tried it after resetting it
If this persists through a custom ROM then I advise reseting your flash counter (not needed as you used the Exynos exploit though) and bringing it back to stock then sending it straight into Samsung as it may be a problem with the LTE chip itself

I finally decided to upgrade from my Nexus 4 to a Z1, and I moved my Three UK contract SIM into the new Z1, it installed the internet & MMS settings and it was fine. But all of a sudden completely random the speeds will drop, the ping will go into the 800s and I can't really load anything on my device.
I'm really not sure what the issue is, whether it's a problem with the drivers, a problem with the actual antenna or if it's just an issue with the software.
I've just tried a factory reset and I'm still getting the same issues, it will be fine most of the time and then just deteriorate until I just can't load anything. The only thing that seems to fix this is a reboot or turning off mobile data and turning it back on again. Obviously this isn't acceptable when I've just paid this amount of money for the phone.
Does anyone have any ideas? I don't want to flash another ROM in case I do actually send it back because won't it void the warranty? If not, how do I go back to stock if I have flashed another ROM?
When putting the SIM back in my Nexus 4, there's no issues at all as there wasn't when I used it before.
I'm really lost, I love this phone but it seems I may have to send it back... Help appreciated!
Contact Call Center of your Provider an tell them to give you the right settings for internet and mms, the settings installed automatically on Z1 not always work. They will send you an sms with the installation. I had similar problem solved with the sms.
Anyone have a fix for this? On Verizon and after almost 4 weeks I have lost my cellular service and data. I noticed when I went to check up on my phone right now that it was finishing a boot-up screen and then never had any bars at the top. Dug deeper and found no service at all. Wiped dalvik and cache and seemed to be bars for under a second and then gone. I am on sensei kernel and am thinking about doing a factory reset and reverting to stock kernel. But I really don't want to lose the benefits it came with.

Well, this is odd. After a month of perfect service, I suddenly cannot get LTE, only 3G. Even nandroids of prior ROM's will not boot into LTE. Is VZW LTE down or should I do a total clean reformat? i do have factory images and everything is backed up. Just a pain.
Very strange. I was flashing various ROM's (CM 12 based - am testing for someone) and at one point pulled out SIM and replaced it. I checked to make sure it is seated right since then. Again, no longer get LTE.
Was on Sensei kernel as well. Let me try flashing stock kernel from ROM first. EDIT: NOPE! Flashing the stock kernel from the ROM did not do it. Looks like total reformat/flash is next!

I just got my Nexus 6 and I am also on Verizon and had the cell coverage drop too. I backed up my apps with titanium backup and did a factory reset and signal came back. I only had it for a day and went to Canada and on my way back to the US I noticed the cell bars were gone. I was just rooted and boot loader unlocked and otherwise stock. I read online that others had this issue when they got to places in the US that had little or no signal. I also noticed that under cellular network settings it loads up with Global under the preferred network type even though it has an option for "LTE (recommended)" and if you choose LTE, global is never an option again until you do a factory reset and it loads with it pre selected. With global selected it works perfectly with calls and LTE, so not sure what that means or if my selecting LTE made it drop the signal after going back from Canada.
Yep, total flash of factory image fixed it. Sigh. Early enough in the day for me to get everything set up again.
Same. About to do it too... I've done too many factory resets with this already. Kind of annoying.
I am in the same boat. Had no problems until I flashed bliss 1.5 then was stuck on 3g. Tried a clean flash of Slim and still stuck on 3g. I will try a stock rom but I am not very hopeful at this point. It's looking a like a reformat here as well :/
Ended up having to format everything and start from scratch again. I'm running a stock ROM now and in weary to try another cm ROM
Don't know if it'll help, but try LTE Discovery app in the Play Store. I use it from time to time to reset my data connection.
Having the same issue, running CM12 daily, have been for a week or so. Midday today it drops LTE, 3g data was working, then a few minutes later to no data. I didn't change anything, nothing new installed. I did reboot the phone at some point before this but that is all...
My only fix was to backup via trwp, restore stock rom, factory reset, reboot & let sim activate, then restore cm12 via twrp... it's a 20-30 min fix all said and done.... pita
Maybe its something Verizon is doing, because I didn't change anything and then next thing you know no data. I hope it's a simple fix for CM12 but I see this popping up more the last few days. Hopefully someone will figure it out. I like CM and prefer it over stock but I am not going to do this multiple times a day just to keep CM...

I just checked and global is still an option for me. I've bounced back and forth, looking to see if anything changes..
Same thing has happened to me last night, lost connection to VZW cell and data. Looking at the field test menus, it seems like the SIM/device understand GSM but NOT CDMA anymore. So I believe the issue has something to do with that. Tried everything, but will nuke and repave most likely....also lost Global as well. and LTE Discovery shows GSM stuff nothing for CDMA
Tried the SIM in another device and it works so its not the SIM.
OK I tried a world of things to recover like some of you may have....its something in Userdata because if I flash everything but userdata it wont work. I am going to try and recover from the backup I had before this happened to see if that works....otherwise rebuild from scratch
will post back
UPDATE: So restoring a backup seems to be ok once you get the SIM back.
Having the same issue over here as well... After a month or AI of having the 6, now I randomly drop service where I would normally have full LTE. I almost NEVER get LTE now and am at most on H with a couple bars then it drops out again. Have also.noticed WiFi connection is very shakey.
Any one find a fix?
I had an issue where i couldnt get my phone to connect any network. Took me long rime to realise, that entering my PIN-number too fast caused the issue xD it unlocked the sim, but didnt let me connect any network... Dunno if this helps anyone, but definetly the most cryptic issue I've ever had.

Troubleshooting my wife's N6 here. Your PIN issue doesn't make sense to me because the phone should be connected to the carrier when locked. Are you talking about WiFi? Because that should be connected too when locked unless settings have been changed from their default (ie, turn off wifi when locked/asleep or something)

I'm talking when you turn on your phone and it asks for pin number to unlock your sim. Some how it seems that if you enter your pin too fast, it bugs the phones radio somehow and you can't connect to your carrier but if you wait like 5sec before entering the pin, it connects to the carrier and the (!) Mark goes away. Try rebooting the phone and see if it helps? Even I think its a weird issue
Edit: OK, just pinpointed MY issue. I have to wait for the "no service" text to change into "emergency calls only" before entering my pin or I don't have any service just the exclamation mark :/

Thanks. I told her about it and she will give it a try, or just remove the pin altogether as a test. It is a weird issue. She is missing important calls from her elderly parents at night and it is rather frustrating. Turning wifi off also seems like a bad fix.
