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 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.
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.
The phone bricked during an OTA so I had to take it to an AT&T Service Center who blasted the phone and installed the latest version, all seemed well until I got home.
WIFI will not switch on the WIFI icon goes green and the slider goes over but nothing. If you clean and then go back to the WIFI it reports off and the slider will not move to ON.
I factory reset the device in case it was something weird but no - cannot enable WIFI.
Anyone have any ideas on how to resolve this or is it back to the store for me and a defective phone
Thanks for any advice offered.
Chris
Maybe it is a device problem if no-one else has experienced this?
What country do you live?? Is very known that the Samsung Galaxy has wifi problems with some countries and carriers, I made an apk to solve this, but your phone need to be rooted...

I updated to marshmallow 6.0.1 a few days ago and the phone was perfectly fine. Just yesterday I factory reset the phone because I've read online the battery is better after that so I did it and restore my data with smart switch after. The sim card was working last night. I fully charged the phone and unplugged it and left it there until morning. When I woke up i noticed that the phone is stuck in emergency calls only. So i just waited the whole day for it to reconnect it self because this happens when i lose service (i rarely do at home but sometimes). Till now I still cannot connect to a network. I tried rebooting, resetting the network settings and selecting the available network providers from the phone search. after doing the search it did not include my own carrier (mobilicity). I am in Canada and the phone is the Canadian variant. The phone search showed telus, bell and wind and cdn roaming. I reinserted the sim card no luck. I can try to factory reset but I doubt it would work. Any one can help me out????
BTW the phone is UNROOTED no mods or anything done to it.

I did some research I think there's something wrong with my Sim card as I can't scan my network through the manual scan. So I'm gonna replace it tomorrow and see if that fixes it. If not then I may just switch to another phone.
