[Q] My mobile data disappears until I reboot - Xperia Z3 Compact Q&A, Help & Troubleshooting

Hi XDA, I bought a Z3 Compact a few days ago, and yesterday this weird bug occured for the first time. The data is simply turned off suddenly when I check my phone, and nothing I do will turn it back on.. Toggling mobile data back and forth, searching for networks and clicking different ones, downloading internet settings again, airplane mode on/off etc. - nothing works except rebooting the phone, and then the data works again until next time it messes up. It did it again last night.
I googled the issue, and it seems some S4 users have had same problem with Android 4.4.2? Link to the issue is found here http://support.t-mobile.com/thread/70532
Apparently they report that you cant make calls either when this bug occurs, even when the phone says it has bars, however I havent tested regular calling. I will next time my device bugs out.
Has anyone experienced something similar and/or is there any way to fix it?

I had the same issue but only when Stamina mode was enabled. After a few hours I would lose mobile data and only a reboot would restore it. I cleared data for Eco Mode Controller, rebooted and the problem hasn't reoccurred since. Not sure if this helps or not.

I don't have it enabled, but I will definitely try clearing data for eco mode controller.
Also, I figured out that I can still make calls even when the data doesn't work. So it is not the same issue that is described in the link.
I think you have the same issue as described in this link? https://talk.sonymobile.com/t5/Xper...sappearing-in-Stamina-mode/m-p/845155#U845155
I have had stamina mode on however, so I will try it anyway.

I believe I had the same issue as you: cell signal dying after a while, but more often when cell reception was likely to be cut off (e.g. poor service areas or stamina mode). I'm also on T-Mobile in the US.
You can try the troubleshooting steps I took in this post, but what ultimately ended up working for me was a nano-SIM swap.
If you try all of the above and still haven't managed to fix it, I would suggest a phone swap.

But if the sim card was the problem, I wouldnt be able to make calls right? I mean, there must be a connection since I can call.
Also, the phone doesn't give me a notification with "No sim card" or something similar..
But then again, weird errors can happen.. I will order a new sim card if the problem persists and I am unable to find a solution

You might be right. My issue was signal, then no signal. I never got a "no SIM card" message, however.
Best of luck!

I am now getting this issue without using Stamina mode. I am currently sat at work with no data, same thing happened yesterday. It worked fine this morning but at some point it has gone and only a reboot will get it back. I am missing important notifications because of this.
It seems to happen when I move around the building and the signal goes weak. The About -> Status page currently shows:
Signal strength: -79 dBm 17 asu
Mobile network type: HSPA
Service state: Voice: In service - Data: In service
Mobile network state: Disconnected
This is so frustrating.

Just rebooted, data is back and now I see this in About -> Status:
Signal strength: -75 dBm 20 asu
Mobile network type: HSPA
Service state: Voice: In service - Data: In service
Mobile network state: Connected
Time to seek a refund.

I never got this issue fixed, even after repairing the device using PC Companion so I've sent it back to Clove for a refund. I think Bluetooth may have something to do with it though: I use BT in the car and have a Fitbit connected. I spent a day with BT disabled and the issue did not occur. I then went for a run with BT headphones connected and when I got back I had no mobile data again.
So goodbye Xperia Z3 Compact.

Anyone managed to fix it?
Hi!
I have the same issue. I use BT in my car too, but I think I lose it event without BT sometimes..
Anyone managed to fix it?

Just wanted to pitch in that I have the same problem (Z3 here).
I was going to return the phone but reading that the new lollipop update will arrive next week I think I'll hold out and see if that update won't fix it.

See if Paul Wheeler3's post here works for you , I cant paste the link since I have posted 10 times here... but google with his name, and search for Xperia Z3 Losing Data Connection. should be one of the top hits.

COPIED and PASTED for your ENJOYMENT:
I thought I’d share a quick tweak that applies to most of Sony’s Xperia Android phones. If you’re on the Three network and travel around a fair bit you’ll notice that occasionally you’ll lose the data connection and it won’t always come back until you reboot the phone. Very annoying.
This happens because Three still have some 2G roaming agreements in place for areas they don’t have coverage. That doesn’t include data roaming however and a lot of devices (including the iPhone still) have trouble with this.
The way to fix this is to set the ‘Network Mode’ to ‘4G/WCMA’. Annoyingly you can’t set this in the ‘Mobile Network Settings’ section, you’ll need to go into hidden service menu to get to the setting. From the dialler, type this:
*#*#SERVICE#*#*
'Service' is typed as you would on a T9 predictive text keyboard, so thats one key press per letter.
Once your into the service menu, choose ‘Network Mode’ and then within this menu choose ‘LTE_WCDMA’.
You’ll see the radio stack reboot (so you’ll lose your connection while it does this).
No longer shall you experience the annoying ‘data never comes back’ issue.
It goes without saying that changing this setting is at your own risk.

You should manually set your network to WCDMA/GSM first. Then do as suggested above.
The problem is that the mode will automatically fall back to whatever is set in the UI if you even load the Mobile Networks control (by simply selecting the menu item in settings). If you leave it stock, then going into mobile networks will cause it to "fallback" into the failure mode. But if you manually set it to WCDMA/GSM then going in to Mobile Networks will only cause it to fallback into HSPA+, which isn't bad.

I'm getting this exact same issue but on my galaxy s5 only a reboot will resolve it I wonder if it is also in relation to 2G networks. I am on EE and the just recently sold to BT could be that their infrastructure now includes 2G coverage with no data for some places? Soon as I reboot back on 4G. Looked in settings and annoyingly only auto ones are 2G/3G/4G and 2G/3G there is no 3G/4G auto connection type guess I need to find a Samsung secret menu?

I am on a tmobile z3 and it says N/A no matter which mode I put it on in settings and then going to that secret menu. Please help. I'm on stock android 5.0.2 lollipop. Thanks!

still have the same bug with my Z3 compact, Android 6.0.1 and it is very resistent, even secure mode without 3rd party Apps, new SIM Card and new mobile phone (but with restored Sony Backup) helped. Vodafone germany and Sony Customer Care are idealess.
Last try will bei leaving SD card out and a reset with Sony companion without restoring backup

Does anyone know the significance of greyed out network icons?

I upgraded to R3A last week and so far everything's gone smoothly.
The only thing that's bugging me is that the network icon (H) spends most of its time greyed out (see screenshot). I only ever saw it in that state briefly in previous firmware.
It doesn't seem to affect connection or call quality. It's not indicative of a bad signal, as it'll still go back to 2.5G when 3G is lacking. The resulting G will usually be grey as well.
Presumably it means something's less than optimal, but I can't find any info about it anywhere.
Clues anybody?
Are you sure you are able to connect to a data connection, for web browsing etc? Because the last time this happened to me, i was not able to connect, and had to do a hard reset to get it fixed.

Data connection works fine. There appears to be no issue with functionality of anything.
The set of "custom" status icons (colored ones) doesn't contain icon for HSDPA (or something like this, dataconnection available in you location) so it is shown as standard icon (only black&white). I bet if you have only EDGE or GPRS available, there will be the same icon as the others are.
it should mean that data connection is unavailable at the moment (because it can get back in a later time) or something is wrong with your data connection (that is why we have sometimes to reset the phone to make it work back).
Guys,
I have a Xperia for almost one month, and last night it suddenly stopped to be connected with the network. I tried to connect manually, and it worked, but the calls still couldn't be done! One hour later, the same situation started again and my phone can not connect to the network.
I don't know what to do anymore, I have already hard reset the phone, and nothing happened!!
Help me!

I get exactly the same thing, running Jacks latest lite-ROM, based on the R3A. Connection icons are greyed out, but I still have an excellent data connection.
What's more is that after a fairly long call, the phone usually looks like it's in flight mode. However, if I try calling myself from my second phone it works just fine, and I can recieve sms-es. But, I cannot send texts or call out, since the phone thinks it's cell-module is turned off. This always corrects itself after a soft reset, and usually passes by itself after about ten minutes. But the connection icons stay greyed out.
If I try to turn the phone-module back on, nothing happens.
Weird, innit?

App Blocking 3g Access

I currently have something on the phone not allowing 3g access. I can't seem to figure out what it is, but I believe I narrowed it down to an App. I did a wipe and clean rom install and 3g was working fine. I did a titanium backup restore of all apps with data and now 3g isn't working again. Anyone know of an easy way to pinpoint what is blocking my 3g? I tried ending all tasks in advanced task manager, but I'm guessing the phone would need a reboot to bring back 3g?
Have you check you settings-wireless & networks-mobile networks-use only 2g networks?
ya I tried using only 2g network, I even tried researching the network and it finds tmobile in the settings. I even went as far as getting a fresh sim card prior to wiping the phone. Somehow after an app/data restore from titanium back up, tmobile internet no longer works still. It's why I wiped in the first place.
1) Double check your APN settings in settings > networks > mobile networks
2) In dialer, dial *#*#4636#*#* > choose phone info > scroll down > verify that 'set preferred network type' reads WCDMA preferred.
3) Also in settings, make sure you didnt set 'use 2g only'. Same location as #2 above
Thanks for your help. I actually just did a nandrestore from an image I had that was a week old and internet came back, so it has to of been something I done within a weeks time. I just hope I don't end up hitting the app that stopped it, if I think it was one, because thats the only thing that makes sense to me.
I have your same problem could you be so kind as to attach the img you put so I try too? thanks

you mean....?
i Think i have a similar problem... I turn 3g on and after half an hour i cannot access the internet anymore... The sign in the notification area shows the "sent arrow" blinking but the receive arrow does nothing... I have apndroid to control my 3g usage... I unistalled it, did a reboot but again the problem persists... Do you have anything in mind???
I forgot to mention that the exact same thing happens with 2g network as well

When someone does a nandroid backup, it backs up all the data on the phone. All of it, if you restore it to your phone, you will be logged into google as him, you will have all his contacts, messages, settings etc. If one of you downloads something, it may download on both machines. The only way to fix it would be to wipe both of them.
i have the same problem. two days ago its working fine. i just turn on turn off the wifi and it just works again.
Can also try turning the airplane mode on/off. This problem occurs if you use APNdroid or similar, or toggle mobile connection on the Desire ROM.
tired of trying and try to wipe, reset, several rom, so I decided to send it to HTC in England ... and the problem is which has the bootloader unlock my ...

No incomming calls while in 3G (UMTS) Network

Hi all together.
I'm interested if someone else can confirm this Problem. Situation:
- HTC Incedible S (brand new )
- Provider: Orange Switzerland
We suddenly recognized, that it's not possible to call this phone . The caller just get's a voice-info that the "The person you have called is temporary not available. Please try later". But the other way round works perfectly, so a call-out FROM the Incredible works fine and everytime.
I did some investigations and discovered the following:
- When forcing to 2G (=GSM) the Problem disappears.
- When forcing to 3G (=UMTS) the Problem reappears - but...
- ... when at the same time "mobile data connection" is active --> Problem away!
So when i'm at my home then the WiFi-Connection automatically get's active and the "mobile data connection" get's offline. And in this situation no calls reach the phone any more. If i manually disable WiFi (and then "mobile data" get's active again): Voila, everything is ok.
Reenabling WiFi - mobile data goes off: No more incomming calls.
Disabling both WiFi and mobile data: Also no incomming calls.
It seems that the incomming-call-signaling is handled in a way that requires an active mobile-data-connection. This seems to be a little bit odd.
Thanks for any ideas or just a confimation that i'm not alone.
Oli
P.S.: Of course i called the providers hotline. But they just said that there is no problem in the net. I should try it a few days later agein. Damn...
Hmm sounds strange....
The only tip I can give currently: goto settings - WiFi & networks - mobile data. And check the mobile data always on.
It's not a real solution, but should fix it for the time being.
But it is strange... Should not happen, maybe there are some problems with there network, so keep trying for the next few days. Otherwise contact them again.
ah! I believe this is something to do with the network provider. Do you live in a place where the network coverage is midiocre? I have the same problem with the iphone 4 (with the bumper )... sometimes even I am not able to make calls... so I have to switch off my 3G! it is indeed odd coz it interupts with the wifi! Did you try doing a master reset?

Thanks for this idea, but this option was already checked. This seems to be the default, so all my tests (as described in the first post) ran under this config (e.g. "mobile-data-always-on" is checked)
Hm. Still hope for any other ideas.

No, it seems to be a pretty good UMTS-coverage. And the mobile-data-download-speed with HSPDA is really fast (1-2 MBit/s). And when i go outdoor the signal-strength (as shown on the phones display) goes up to 4-of-4-bars (100% Signal). And still: incomming calls not working.
So i think the 'physical' Network-Infrastructure is not the problem. It's obviously a netwrok-logic-problem.
Thanks a lot for your help/ideas.
Ok, some new observations.
The problem of "no incomming calls while connected through UMTS" seems to be a local problem of the network-cell/Antenna around my home.
If i'm about 500m away then the problem seems to disappear..
Of course i did not test every Antenna of Orange Switzerland
Another point: I wrote that the problem just occures when i'm booked in in UMTS AND mobile-data is inactive. That's not completly true, as my newest investigations show: The problem is also present if UMTS-mobile-data is enabled.
But it dissapears for some seconds while and shortly after there is mobile-data-traffic.
Example:
- UMTS forced (no GSM), mobile-data enabled, WiFi disabled
- Phone 'idles' some minutes, no background data-transfer
- Here the Phone can not be called
- Now i go into Android-Market, search a 'Big-App' (10-20MB) and start download
- While the download is in Progress the Phone CAN be called
- A few seconds after the download completes, the Phone still CAN be called
- But later - let's say 60 seconds - the Problem re-appears.
So it seems that an active data-transfer is like a 'heartbeat' for the Orange-Cell and the Cell registers the phone as 'online'. But when data-idle the heartbeat is missin.
I will make some more calls to the Orange Hotline

did you solve it. i don't think thats the case certainly not for me as i'm having exactly that issue of no calls while in 3g mode but if i go back to a stock rom its fine. so the reception distance/signal is identical (i.e i haven't moved anywhere) and its fine on one rom and not another so it must be software (in my case)
So, hi together.
As the original poster i can now confirm that the described problem dissapeared.
We had nothing to do - so no change of any settings nor doing any software-updates. It's simply woking again.
So i'm no pretty sure that the problem was just a local one, in exactly out network-cell. No problem of the device.
Nevertheless: Thanks all for yout infos and tipps.

3g/H packet data problem - N7000

Hi there! would like to seek your help regarding my galaxy note, I encounter packet data on/ff and cannot connect to mobile data (internet) but my sim card is working (can send sms and call). i just put my phone yesterday to flight mode and after that it cannot able to connect to internet. I did factory reset and some wipe of cache.. is there any advice? my phone is rooted already with franco kernel (stock ICS rom only). Please help Sir.
Please do not "FACTORY RESET" , You could potentially brick your phone.
1. Try to see if you have your "DATA" on. With DATA off 3g/h/h+ will not work only wifi would.
2. Worst case scenario, take out your SIMCARD and put it back again.

Hi, Thanks for the reply,
I already did some of the basic steps, It just so happen that the history of this problem was because after I put my phone to "flight mode for about 5 hours" and the the packet data icon "3g/H" were no "DOWN arrow" color orange where as I know is a sign of good connection. but the icon only lit the "UP arrow" please help
May also be a issue with having incorrect APN information (Some carriers do not Automatically push out the right details)

Hi, Actually my phone's packet data was working well before I put it in "flight mode" meaning my APN settings is OK. for reference here are some of my screen shots which I edit to see the ICONS status,,thanks for the help!.
Don't know what still seems like a apn issue. Only because I would expect atleast one reply from the network during the connection discussions.
The fact that the orange arrow never lights up to me indicates that the network never gets the sent packets.
Have you tried anything like the apn on/off alps from the the playstore.
Otherwise I cannot see why having airplane mode on for a while would permanently ruin your data connection

Hi, yup but as you know some apn tweatering app is no longer feasible with ICS,
Yes, I am also not convince about after flight mode / airplane mode activation that causes my phone not to connect to the internet. I guess this is related to root bug, this was my 1st time to enable flight mode under rooted condition so I wonder that this might be the root caused. Can anyone suggest to unroot? Please advice, Thanks and Mabuhay!
Bump
Sorry to be bumping this old thready but was the OP able to ressolve the problem? I have been having exactly the same issue but only intermitantly, if I reset my phone everything is fine for a while and then all of a sudden I loose the orange arrow and will only see green.
I am unable to recieve calls or make them, no internet etc. I am on Tmobile UK now EE, have gone through the standard error checking with tmobile but no luck, first they said it was the network being down and no they say it's my phone but I don't see how it's been fine for ages and all of a sudden I have this problem.
It's totally random, I have decent reception so I have say 3g or h+ with 2 or 3 bars but no orange arrow
Any ideas?

Mobile Data connectivity Issues & Spen Button loose?

I know people have had Wi-Fi connectivity issues...but has anybody else had Mobile Data connectivity issues? It's a new phone and a new sim card but I'm still having issues? I had to reset my device in order for me to browse the internet or for me to send texts...TWICE within an hour. Any suggestions for this?
Also, is anybody's SPen button loose? I don't know how secure it's suppose to be, but if I run my finger back and forth as if I'm rubbing it, the button rocks back and forth as if it's loose. Not sure if it's supposed to be as secure as the home button on the phone or what

Wi-Fi and Network issues are being experienced by just about everyone. Because it's so widespread, this leads me to believe it is a software issue and we just need new radios.
Your SPen is like mine. Fairly certain it was made this way and is not supposed to be like the Home button.
Cheers
hum funny i havent had any wifi or 4g problems. I remember they said the s7 edge had wifi problems where it would randomly disconnect and not reconnect.
Which i didnt have that problem on the s7 edge either. (got the phone 2weeks after launch).
But with the note 7 no problems here. And my spend is pretty stiff no loose feeling on the button, feels almost like the home button
I've had really bad issues too. Like having to restart my phone to get data to work. receiving text messages late. Phone calls going straight to voicemail.

Same here. I simply notice that after an hour I dont seem to receive any kind of notification, suspicious. So I check my phone and keep getting pop up of "no connectivity please check your network". Both Data and Wifi will not connect. Even toggling airplane mode won't establish a connection. Only option is to reboot. This has been happening to me at least twice a day.

I have been having those problems too except it's with my data and regular service. If my phone loses service somewhere the only way to get it back is to restart the phone it's ridiculous and the signal is way worse then my wife's S7 Edge

id say report it to samsung via online chat and they will make a case about it and hopefully they will make a patch.
but as said i dont get that problem. Background data and everything works. my package tracking, ebay, facebook and all that work. No miss called or messages.
Definitely have an issue when I roam on AT&T then come back to a T-Mobile area. Have to put it on airplane mode and then back for it to acquire the network again.
I haven't had any WiFi issues, but I rarely use WiFi. I have noticed that my Note 7 like to switch to AT&T Edge (which is basically unusable for data), even when there is T Mobile LTE available. I constantly have to manually search for a select T Mobile for it to switch back. I don't want to disable roaming, because it's necessary where I live, but I can't seem to keep the phone from switching over to AT&T or get it to switch back to T Mobile when service is available. I just switched from a Nexus 6P which very rarely had this problem in the same area.
I too have experience Data loss where I have to toggle airplane mode or reboot. But this only happens at my residence which has a poor to fair T-Mobile signal.

I had no issues, maybe don't use phone often enough to notice, but I have been in and out of network and it works fine without any reset. but here is the funny part: when i went to activate my N7 (from home computer), I had to call rep, of course from my old phone. So while he is trying to switch me, he sms me some code to input (still on old phone), didn't get it, sends again, nothing still, then my old phone connection goes dead. So i grab my new phone, sure enough, I'm switched, new phone now works. That was around 9pm. 3AM my phone beeps, I got 2 SMS messages with codes from 6 hrs ago. Since they were originally send to my old phone, which worked fine like forever, I would speculate the issue was on TMO side, not my phone. So I wonder if some of the issues some of you experienced are coming from T-mo? I don't know, like somebody forgot to program new phone into system and things hang up,
I switched the mobile network selection to manual instead of automatic and turned off data roaming and haven't had this problem since.
I have had no issues like this? Why are some many users having issues with this phone. The Note 7 is built pretty dam well. All my friends i know have this phone and no issues with them as well. Before jumping the gun on issues please do research.

I'll try this and keep an eye out. Next step for troubleshooting will be to get the SIM activated that came with the N7 instead of using the one from the S7. I've read that using a SIM from a previous phone has information stored on it and could be the cause for some problems. That just doesn't make much sense to me since they both have the exact same T-Mobile bands but I guess you never know. Thanks for the tip!
I have noticed on my N7 if I lose service (building elevator, etc) and then come out into open air, one out of 5 times it never reconnects. I try to cycle through Airplane Mode and out, but that does nothing. The only way to get data back is by restarting the phone. Super annoying, especially when I have a password on the phone and a sim lock so by the time phone is back up and running to use, it takes some time. Very frustrated with this!

I too have experience Data loss where I have to toggle airplane mode or reboot. But this only happens at my residence which has a poor to fair T-Mobile signal.

I just experienced this. Ironically I had full LTE Data bars but 0 connectivity running T-Mobile stock Firmware and NOT rooted.
At least 3 times in the morning my data has been off, showing full bars but no LTE, a reboot was the only thing that got it up and running again.
As for the S-pen I'd say it's semi loose when fondled..
