Hi guys,
I'm still working on figuring out the connectivity issues of my O2X. My problem has been that my data connectivity intermittently drops out, and fails to establish one and move out of WiFi range.
I have completely reset my phone to stock with the latest updates available in Norway. This is baseband 622, and version number 10c. The problem I am consistently having is that whenever I have stayed on one connection type (WiFi or 3G/edge) for any length of time and then switch, the phone fails to establish a connection through the other service. This means that whenever I have been home connected to my WiFi for awhile and move out, mobile data is not established. Similarly, when I get home, it does not automatically connect to my home WiFi network. In both cases the solution is to turn on and off WiFi mobile data (sometimes several times) to re-establish the connection.
If I quickly moved in and out a range of my WiFi, the switches between the two connections without any problems.
This is with everything stock. Is there any point in trying the other basebands? I have tried a few of them already, but without consistently good results.
The alternative solution is to send it in for repair, but they will only tested, figure out that they cannot locate the problem because they do not have the funds stay with the same connection long enough, flash the phone with the latest firmware, and send it back. After repeat this three times, I'm entitled to a refund or a new device, but it means that I will basically be without my phone for around six weeks.
Any and all solutions are greatly appreciated.
Edit: I guess a possible solution is just to use Tasker or something similar to reset mymobile data connection when I leave WiFi, and regularly reset WiFi when on mobile data.
I believe I have the same problem.
The 3G data connection would drop about every 10 minutes.
I got the phone a week ago and it too came with 10c firmware and 0622 baseband.
I believe that this is a hardware problem because I have flashed other firmware + baseband combos and yet this same problem still occurs.
I have sent the phone back for repairs yesterday. I hope that they can fix this problem.
Again, its probably baseband related....
Same for me here

1) Modem. My baseband is recognized as P1000XXJPZ. Dialing *#*#4636#*#*: network set to GSM only (tried others though), network signal detected but GSM is "emergency calls only" and network signal indicator shows no signal. SIM is recognized (and works in other phones), can access contacts. Can find networks if I search manually but can't register on my network. Above thread suggested copying modem.bin to /system/vendor/ - did so, no effect.
2) WiFi. See the screenshot of battery usage - since I'm not using GSM or 3G due to issue #1, I normally disable radio altogether in *#*#4636#*#* and enjoy long battery life. However, CM10 did something sinister to the WiFi and the battery drains by 50-70% during just one or two hours of Google Talk via WiFi (provided I'm sitting right next to the access point). With WiFi switched off, the tablet can last for days - music, reading, etc.
My install was clean - data, cache, Dalvik cache all wiped, no custom kernel, etc. Everyting else works flawlessly, but these two issues are killjoy.
Does anyone else experience these issues? Does anyone knows why does this happen and whether it's possible to fix?

Same here.
Am thinking tht flashing an old rom might solve the problem.
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.
---------- Post added at 12:43 PM ---------- Previous post was at 12:36 PM ----------
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.
/Edit
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
I have found that whenever my phone loses signal and then regains it, I have no data connection until I restart the phone. Even toggling airplane mode or manual signal search does not restore data. I have tried disabling 4G but that doesn't make any difference. I also don't have WiFi on as I never use it.
Does anyone else have this same problem and know a solution? It is extremely frustrating having to restart my phone up to 5 times a day and not receive emails etc.
I had more or less the same. What helped in my case was adding the apn of my provider manually instead of letting the network and phone handle it.

this can cause by network or firmware bug
you can manually add APN if system delete it then repair Firmware by PC Companion
:good:
I have the same issue.
Have you managed to resolve it yet?

Not yet. I have tried deleting the apn end adding it again myself but it's the same.

my problem may be slightly different in that I could not connect to Internet when out of wifi range unless I did a restart.Resolved by switching off stamina modes.

It works for me. Next week the Z3C will be updated to Lollipop. Let's hope it will solve this bug.
Good day, guys. I have a problem. After update to 8.1 I have an issue with recieving calls, when some people call me and 4G mode is on (4G network type is enabled in mobile network settings) sometimes they can not dial to me, it seems like my phone is turned off and there is no signal. If I change mobile network mode to 3G, there is no problems. Also when people can't call me, I can make calls to them and there is no problems with connetion and mobile data. (connection level is full).
It looks like there is some energy saving mode of radioband module and It doens't work properly.
So I've changed SIM-card and changed the mobile operator to another, the problem still exists.
In the safety mode, the problem still exists too.
Also factory reset from recovery menu (wipe data) didn't help.
Is there any fix of this problem? I can't redownload the firmware with OST because of error. Thank you a lot.
I have similar problem, did you find out how to solve it?
