Hello,
I´ve been hafing my XZ1 Compact for 2,5 weeks now and it´s been working OK but;
It has been a little strange for a couple of days now:
After running WiFi at home and then coming out of the house, it has been difficult to find 3G or 4G networks - And the solution has often been to put the phone in "Airplane mode" and then deactivated it after a couple of seconds and then the 3G or 4G data traffic network has been working again (depending on which network selection I have made).
But now, it has lost both 3G and 4 networks permanently, no matter how I try to activate it, it´s not working anymore.
I have done the following:
- Several reboots
- Upgrading to the latest software on phone
- Disabled Stamina Mode
- Deactivated data saving
- Attempted with "Airplane Mode"
- Trying to have WiFi and input and let the phone choose itself
- Still have lots of GB on my monthly traffic rate
The telecom operator is Tele 2 and it's a business phone and data traffic settings are correct what I can see and no other colleague have any problems with their phones (not Z1 Compacts then).
- Does anyone have any tips?
Greetings Zeb
I don't experience any of those issues at all. Have you made sure, that your APN settings are correct? Try deleting them and setting it up again maybe?
me neither.
try:
Software repair (not factory reset)
another SIM
APN
another area.

Hello,
My I9000 has a peculiar problem: While both mobile internet and Wi-Fi work fine, switching to 2G when 3G/UMTS/HSDPA coverage is bad does not. It ends up losing network connectivity completely in areas where other phones have no problem staying connected by switching to GPRS/EDGE. (3G coverage is spotty here at times, so this matters quite a lot.)
This problem has first appeared rather spontaneously when it was running its stock 2.1 firmware and has persisted through upgrades to stock 2.3 and CyanogenMod 10 through 11. I've attempted to switch modem firmware to mitigate it to no avail. (Modems XXJVT and ZFJPG/BVJJPG were tried, no difference was noticed - I am rather wary of messing with modems further, as this is my only phone and I'd rather it still could call at the end of the day.)
Moreover, if network mode is switched to GPRS/EDGE manually, it can't be switched back to 3G (either manually or automatically) without a reboot. (The 'set preferred network type' field in *#*#4636#*#* starts resetting itself to 'Unknown' spontaneously at this point.)
Unfortunately, I don't know many details of the incident that caused the appearance of the problem, as I was not the owner of the phone at the time - I only know that it was roaming nationally (within the same country) at the time. (The network type should have been the same, and it's not like it's stuck in roaming in any way.)
Has anybody encountered such a problem before? Is this likely to be a hardware problem, or could there be a software fix?
Thank you in advance for your thoughts.

you need to try fiddling with its network settings (read this for info only) you can use service codes on i9000 to set your network settings . Sometimes it may be due to network settings not set to Auto and set to preferred and at other times it could be antenna connection inside the phone having poor contacts.

Thank you for the hint. I have tried setting the "Select radio band" setting in *#*#4636#*#* > Phone information to European bands manually, and this appears to have mitigated the problem at least partly (phone has switched to 2G and back a few times during the day). I've noticed that it would sometimes just turn mobile data off despite having a good signal, not sure if this is related. It also sometimes seems to prefer another operator's 3G network to its own 2G ("emergency calls only", network mode is UMTS/HSDPA), but this is only guesswork since I have no way to actually confirm that the areas where this occurs have 2G coverage (it just seems really unlikely that they wouldn't). Maybe the fact preferred network type is "WCDMA preferred" factors into this.
TL;DR: Forcing radio bands seems to have helped, other radio weirdnesses remain but aren't nearly as bad.
Hi
I am in Kolkata India and recently switched from a 2G to a 3G plan with Vodafone Kolkata. Ever since then, my problem is that I am unable to connect to 3G using WCDMA. Neither voice nor data works. If I revert to GSM only, then voice and 2G works fine. Wifi has been fine and my saviour at home.
Phone details: Sony Xperia SP C5302 running Android 4.3 build 12.1.A.1.205.
I have confirmed with network service that it is not a SIM card issue, by carrying out the foll. tests already
1- Signal strength in the area of use : At the time when I am unable to connect to 3G, my colleague sitting in the next desk and using a Motorola phone is consistently able to connect to the same 3G network from his phone. So the network strength must be fine.
2- SIM damaged or dirty - I have obtained a new SIM card as replacement, after this problem started, from my service provider yesterday. But the problem is not resolved.
3- Manual network search and connection - I have tried this many times, using WCDMA only or WCDMA(Preferred) options. In either case, only on rare occasions, the phone was able to connect to a network. However, 3G data connection (H+ icon) did not show and then the phone disconnects from network. On most occasions, when I manually attempt to connect to the 3G network, I get the message "Could not register to the selected network. Make sure SIM is inserted."
3- Trying different SIM/Handset - I have tried out both options of switching SIM and handset.
- My SIM on Motorola handset - connects to H+
- Another SIM on my Sony - momentarily connects, then disconnects and then does not connect to network.
Please let me know if anyone has faced similar issues and found any resolution. Thank you in advance.

I think that there's an option to use 2G instead of 3G in the settings menu, have you checked to see if that is enabled?

That is the WCDMA option I've mentioned about, there was no other setting for this.
Anyways, it turned out to be a hardware problem. Got the "mother-board" replaced for free as it was under warranty & now working fine!

Hello,
I recently updated my Z3 compact (D5803) to android 5.1.1. on the T-Mobile network here in NYC. Ever since then, I frequently lose the ability to do anything data-based with the phone. No web browing, no chatting on whatsapp. I can still make phone calls and send/receive SMS, however. The data functionality returns when on WiFi, but goes away once I switch back to LTE. In order for me to get data on LTE, I have to manually download the internet settings for my provider to my phone (this is located under the Settings menu in android). Even then, it only lasts for several minutes before the data connection is lost. T-Mobile was unable to fix the problem, and changing the SIM card didn't resolve the issue.
Anyone else experience this?
Yes, many others have the same problem, see various posts in this thread: http://forum.xda-developers.com/z3-compact/general/discussion-5-1-1-stock-released-post-t3162309
Currently, the best workaround seems to be to disable and re-enable mobile data, or to go to airplane mode and back again. That solves the issue until you drop LTE connection the next time, then you will have to re-iterate.

Yes I am having the exact same problem since updating to 5.1.1. As the other reply says turning airplane mode off then on is the quickest way to get connectivity back (swipe down twice from the top for quick access). This is terribly frustrating though, it only lasts for a few minutes. I can't believe they pushed the update with this issue!

My phone had this issue after the over the air update. I reset the phone to factory, wiped all data. Two days on, now, and no more problems with this.
Same problem. I tried factory reset out of desperation, but it didn't work.
Love this phone, but very discouraged by this bug.
(I'm on t-mobile in Seattle, fwiw)

As posted in the other thread, there is now a fix/workaround:
From reddit user FishStik5: Going into the APN settings and changing the APN protocol to iPv4 only (it was iPv6 before) seems to fix the problem.
How to find the setting: Settings-> Wirelessa and Network / more -> Mobile networks -> APN -> T-mobile data -> APN protocol -> Set to IPv4.

Looks like this worked for me (T-mobile, San Francisco area). Thanks for posting this
i'm having the same problem and didn't work for my the ipv4. still loosing data, i have to reboot the phone
I have also problem with that (Orange, Poland). I sent my phone to official Sony service, they reload the software, but I still have that problem. Lte is working for a while and when my phone switches to wcdma (because it is not in a range of lte) it is not working either. However, when I change the preferred network from lte to wcdma it is working without any issues.
Same problem here although I'm on ipv4 [emoji34]
Sent from my Z3 Compact
I thınk you shouldnt buy operator phones. Buy ınternatıonal models next tıme
Mine isn't an operator model, I'm using Straight Talk and also have the issue. It made my phone useless....I almost never have data
This worked for me
This worked on my Doogee Valencia2 Y100Pro
Install and Open app "Hidden Android Settings" (by 0Alex)
Select choose and open "RadioInfo"
Move to Last option "TOGGLE DNS CHECK"
mine read "0.0.0.0 not allowed"
press the "TOGGLE DNS CHECK" so that it displays "0.0.0.0 Allowed"
That's it - my mobile data worked, I hope it works for yo

1. Change "APN Protocol" to IPv4
2. Change "APN Type" to: "default,supl" only
3. Change "APN" to "internet"
4. Save.
Best, Martin.

this is a bug on 5.1.1 sony need to fix it
Any news with this issue?
No problem here with LTE on the CM 12.1 Cyanogenmod flavor of 5.1.1 on T-mobile (that I've noticed at least). But I think CM 12.1 may handle the APN settings differently (mine is set to T-Mobile LTE ipV4) from the stock ROM or it could be something Sony messed up from the AOSP code. I'm NOT suggesting anyone try a CM ROM as a solution as there are lots of downsides to unlocking your phone and flashing any non-stock ROM. But the problem does seem to be specific to the Sony ROM and not 5.1.1 in general.
I also have this problem after the update to 5.1.1 in the Netherlands. The first problem was that the update changed some mobile data settings, so I downloaded the settings from my provider. Unfortunately those settings were also incorrect as I had to manually remove the APN's Proxy and Port (they were set, be needed to be 'not set'/empty). This improved the connection a bit, but it still looses the mobile data at certain places (where the coverage is good). Did a factory reset as the Sony helpdesk suggested. For a few days this seemed to help, but again the same issue came up. The suggested solution mentioned in this thread did not work as those settings are already applied.
I have a profider (Telfort) which uses another provider's network (KPN's). So after the update I also see a annoying R in the signal icon, where in the previous version it always showed H+, H, 3G.
Does anyone know if this is resolved in the new update?
After the last update and a new reconfiguracion on the APN now work correct for me.

And which version are you on? 23.4.A.1.200 or 23.4.A.1.232?
Wondering if anyone can help me out. I've already spent hours on the phone with tmobile and they can't seem to solve it.
I've had this problem ongoing since getting this phone. Basically I get no data roaming. Places Ive tried: Canada (several cities in BC as well as Quebec and Ontario), UAE, Bahamas. I spend a lot of time in Canada so its a real issue. Things I have tried:
- Factory reset
- Upgrade to 5.1.1 using Odin.
- Try sim card in friend's phone (4G works no problem in Canada)
- A bunch of other stuff I don't remember
Symptoms:
- About 50% of the time the phone works for calls and text
- The rest of the time it says "emergancy calls only". Restarting the phone immediately restores ability to make calls/send text. This happens regardless of signal strength.
- Data connection never works. Only time I got 4G was the very first time I entered canada with this phone. . Restarting the phone would make it connect to 4G for about 1-2 minutes before it would lose data connection. Restarting the phone would bring it back. After about half a day the phone completely lost ability to make data connection and has never been able to get data connection internationally since then.
- Sometimes I get this message: "you have lost data connectivity because you left your home network with data roaming turned off". Data roaming is definitely turned on. I've enabled in settings and also via #RON# short code.

This sounds like a config issue to me. the random drops to emergency seems to be issues with roaming not being set up right. It sounds like your APNs are not setup correctly or something. have you gotten any info from t-mobile on Roaming APNs? i'm not sure if it needs to be adjusted for roaming or not.

Yeh thats what it seemed like to me as well but I went over the APN settings with them on several occasions. I also looked them up online. Everything seems correct. The only thing they had me change was APN roaming protocol from IPv6 to IPv4/IPv6.
Dial *#*#4636#*#* (on stock dialer), in Device Information try to change network settings to LTE/WCDMA.
What are your APN settings? Provide info about all fields.
Did u ever solve this issue ? I'm having the same problem...
Hi,
I have my A2 almost one year, and problems with network signal have from two weeks.
Problem is a coverage, and basically the lack of it. The problem i have is only at work, all the time I had coverage in good level, but from a month ago, my phone lose signal (reboot repaired this issue but internet speed stay slow, earlier i had fast connection), but since a week I don't have signal at all in work (all time I have "no service" notification). My co-workers didn't notice any signal coverage changes, so only my phone have this issue. From half year I have Ressurection Remix rom and works great, I think my problem start at update magisk to version 20, but it's only my suspicion. Yesterday i flash new LineageOS on android 10 and didn't install magisk, to test signal on this rom. It didn't help at all. Any ideas to fix this?
Update:
I notice that I can't switch my network to manual. It's on automatic and when I tap to switch, then it shows "can't find any network, please try again". So im limited to one operator and phone didn't switch automatically to other operator, when I don't have network signal.
Have you tried:
Settings -> Network & Internet -> Mobile Network -> SIM slot -> Advanced -> Access Point Names -> Menu -> Reset to Default
?
Yup, didn't help, maybe if I try stock rom, my problem disappear...
