Hi,
After I got the lollipop update to my xperia z3c, I completely discharged the battery and charged it to 100% while off. After I turned it on the device didnt even asked me my sim PIN and there was no network coverage (no cell signal/3g/2g.. nothing at all). I restarted the phone several times, did a hard reset. none of it worked.
After that I tried several other sim cards and they were just working fine on my phone, I also tucked my sim to other phones to confirm the possibility of damaged sim- it was working fine in other phones.
Later I booted up to safe mode and to my surprise the signal was back on. I thought it was a software issue so I booted back to normal mode and my signal magically came back. through the day my battery died and I recharged while off and when I turned it back on the signal was gone again.
I made a full factory reset in the end and the problem was fixed again. But today after a full charge cycle my signal was lost once more.
here's what I did;
*uninstalling all recent app updates
*booting into safe mode (signal is fine) and booting back to normal mode (signal gone)
*turning on/off wi-fi, nfc, cellular data, lte, stamina mode, bluetooth and rebooting with each toggle
*changing preffered network types (wdmnc+gsm)
none of it works.. I'm getting hopeless now, do you guys have any ideas? Do you think it has something to do with full recharge cycles while the phone is off?
I also have very inconsistent battery life. 100 to 95 in almost first 5 mins of booting, 95 to 87 takes a bit longer but 87 to 80 drops quite faster.
your feedback is most appreciated!
thanks
This is happening to me on my t-mobile z3. No clue what the issue is.
Saw this post on the Sony support forums. A few people on that forum said it worked for them.
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-> Wireless and Network / more -> Mobile networks -> APN -> T-mobile data -> APN protocol -> Set to IPv4.
This appears to fix the issue for me.

Hello,
Since a couple of weeks I've been having some issues with my beloved phone: the LG Optimus 2X Speed (P990) running the latest and greatest Cyanogenmod 7. And I was hoping that you could help me with that.
The Problem
My phone, and my previous phones have always had great service reception. I would never find my phone with two bars or less, unless it was brain-dead out of juice. I've always had the same provider (T-Mobile NL) and I've never experienced any problems with them.
However, in the last couple of weeks my phone can't find my network more often and often. I'd check my phone to see why I haven't gotten text-ed in the last minute or so, and it would be offline. Zero bars and status "No Service". At the beginning, I could put Airplane mode on, and then off again and it would reconnect. But since a couple of days that won't work either. I can put the telephone into airplane modus, but it gets stuck in it.
The button remains gray saying "Disabling Connections". If you go back, and into the Connection settings again the button can be pressed but indefinitely keeps the phone in airplane mode. The only way to enable connections again is to completely restart the phone. And as of lately I find myself having to reboot the device about 1-4 times a day.
Could you help me with this?

Obviously CM7 went a little crazy! I don`t think it`s hardvare problem and the most safe and secure thing u can do is to go back to stock rom and root and reflash CM7 again!!! Android is weird system and many weird things happen to many people. If u have few hours to spare u should begin there and see what happens. If that doesn`t solve your problem than u can start thinking about hardware failure (maybe SIM card, maybe phone antena). But i`m allmost positive it`s software isue. :good:
Disable the automatic date and time (network-provided one). See if that helps.
That was preventing my P990 from getting network at all after a cold boot.
Hi,
I have exactly the same problem. Disabling network-provided time helped (i.e. the phone connects to the network and data connection is up), but I was wondering if this is a bug and if there's a thread or a resource discussing this issue? Btw, the phone has been having some minor connectivity issues in CM 7.1 as well, but otherwise CM7 is useable.
Phone: LG-P990 (Optimus 2X), "Made in Korea" under the battery, does that mean for sure it's the SU660 flavour?
Carrier: Fido (Rogers Wireless), Canada
ROM: CM 10.1-20130722-UNOFFICIAL-p990 (tonyp build version 5) (Wiped and flashed on 2013.08.27)
Kernel: 2.6.39.4-kowalski-exp
Basebands tried: (none get me data connectivity)
LGP990hNAT-00-V25h-FID-CA-FEB-22-2012+0 (Original)
725 V10d (shows as Unknown in About Phone)
450 V20m SU660 (EDGE only)
OK, Correction...
Only the Wi-Fi connection was up. The cellular connection indicator was blue, which has led me to believe that cellular data connection was up as well. When Wi-Fi is disabled, the cellular connection indicator goes white and there's no data connectivity.
Furthermore, even though basic cellular connectivity was available for approx. 8 hours during the night, as soon as I left home and started moving it started dropping out. For example, I was only connected ~30% of the time for the past hour (and the reception along my usual route is normally great).
Toggling network-provided time doesn't seem to have an effect now, but the old tricks (toggling cellular connection, going into Airplane Mode, rebooting phone) seem to restore cellular connection for a brief period.
I also noticed that often when I would launch a data-using application (Internet browser, gmail app) cellular connectivity would be lost in a minute or so (saying No Service).
I've tried looking into "logcat -b radio" for ideas, but I don't quite understand what's happening here (willing to learn though).
Help...
I have installed CM7.2 (official CM) and CM10.1 (tonyp 5, oldbl) with dual boot and can now switch between the two ROMs. I have good cellular and data connectivity in CM7.2, but no data connectivity even after a fresh install of CM10.1.
I assume the baseband has nothing to do with this since both ROMs are using the same.
So, armed with a dual boot device, the n00b is ready to do troubleshooting! It only needs guidance now... Help?
Hey guys/gals -
I got my Moto-X a few weeks ago, and have been using it without issue on AT&T. Unfortunately, I'm just wrapping up my first trip through Europe with this phone (left my iPhone 5 at home), and I've noticed a very odd thing over the last week.
For some reason, my phone will not re-establish a cellular data connection once it has connected to WiFi (and subsequently disconnected from WiFi). I have noticed this - consistently - in both Germany and Italy. In all cases, once WiFi is no longer connected, I can see that the cellular data network is available (the 4G or E logo shows up, grayed out, next to the cell bars) but it will not reestablish. The only way to obtain a cellular data connection is to restart the phone.
I've tried going into airplane mode; I've tried cycling cellular data. Nothing I can think to try causes the cellular network icon ("4G" or "E") to cycle from gray to white...I simply cannot get back online without a full restart. But once I've restarted it works fine - so long as I don't jump on WiFi.
The phone isn't unlocked; it's an AT&T device, with no APN tweaks.
Anyone have any idea what could cause this behavior? Unfortunately, it's going to be another four or five weeks before I'm back here to test any ideas...but I figured I'd reach out while the issue is fresh.
Cheers.
Just to chime in, I've also seen this issue on mine, but it only happens with certain WiFi access points. After using the Cisco ones at work the problem occurs, but my Asus N66U doesn't seem to upset it.
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.
Edit: typo

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
(5.1.1) I was on wifi at home. I headed out and have been on mobile data for most of the day. I went for a coffee and my wifi won't work. Tried turning the phone off and airplane mode.
When I click Wifi it says it's on with no networks available. I click More settings and it says Turning Wifi on, but doesn't.
I'd rather not reset the phone, any ideas? Thanks.
yea, reboot your phone.

I had that symptom once, while waiting in a doctor's office. Shutting down and booting back up solved it, but this was a few OTA builds ago (i.e., I'm currently stock, lazy me).
Perhaps delete/forget your current WiFi connections and retry?

My connections don't even show up. I'm gonna let the battery run flat and then try... if not, then reset phone.
I let my battery die, my phone turned itself off after about 4% remaining. 10 hours later and when you hit the power button , it shows the low battery warning, but won't turn on.
So, the battery wasn't completely dead. I needed my phone, I plug it in to charge... And WiFi!!!!!!
Just updated to lmy48m... no wifi again. YAY!!! <_<
I'm having this exact problem w/ my WiFi, and I'm now suddenly getting the "!" appearing ever since updating to LMY48M.
i've been having this problem with build LYZ28J & LYZ28K randomly wifi would stop working. i'd reboot my phone and it would work again then it stoped, so i called Tmo got a replacement this time it took a few days and happened again this time i called Google and they called Motorola they had me wipe cache while i was on build LYZ28J and it worked... then i got the LYZ28K update then 3 days later this morning wifi stoped working again. So i figured doing a cache wipe would work again, but it didn't so i backed up everything and booted into recovery and wiped the phone thinking it would work but that did... still shows Wi-Fi toggle off and says turning on Wi-Fi. Called Tmo again they told me to take it to astore anfd get it diagnosed but im going to call google and see whats up. anyone have any luck getting this fixed ?
I'm also having this problem. Stock 5.1.1
Well I get my replacement phone today let's see if this issue happens I'm going to set it up as a new device.
I had the same problem. I've had pretty terrific success disabling Google Connectivity Service, which I think is somehow related to Project Fi. I went into apps, force stop, disable. Since then, I haven't had to reboot my phone. Before that, I was rebooting, toggling airplane mode, etc.
It's not 100% better though. I have had to toggle airplane a few times. But it's been much less frequent than before.
Suddenly happened today, probably the second time ever. No WiFi saved networks, couldn't locate signals, etc.
Rebooted the phone, everything fine again.
Odd.
- wader
I can not connect at all to my work's wifi where I have to enter my AD username and password, just can't connect. It worked mostly fine before Andorid 6.0
It is flaky on regular WPA2 wifi too at home, sometimes have to toggle the wifi or even reboot.
Wifi on the Nexus with Android 6.0 is poor to junk basically.
My S10 takes a while to find mobile signal after restart or when airplane mode is turned off after turning on. A while here is at least a minute to 2. 60-120 seconds. I don't know this is happening all of a sudden. Happened yesterday while travelling. Also I had installed Cellular - Z and Wifi Man apps before this issue. I used Cellulaz extensively and suddenly now a new issue.
I am sure this was not an issue before. I did a network settings reset, cleaned cache and the mobile signal is really good. Now apps that I mentioned above are uninstalled too.
Anyone faced this issue before ?
Happens only on Roaming
This happens only when roaming and the time taken to find mobile signal is 1 minute . When on non roaming, signal is instantaneously found..within 5 seconds
IDK if it's related (probably not) but I've been noticing my US S10 has lost signal entirely and won't regain it unless the device is rebooted. Happened only twice (so far) but that's still 2 times too many.
