Xperia Z5 :: No Data Connectivity At All When 4G Enabled
Oct 18, 2015
I just got the international Z5c, model E5823, which supports both tmo us LTE bands in my area (bands 2 and 12). When I have preferred network type set to 3G, I get more bars and have data connectivity. When I switch it to 4G, the bars go down to 1 or 2, and I get no data.
I did a logcat while switching from 3G to 4G and noticed that while switching, the icon switches between H+ and H, then eventually drops out. I'm still trying to see if there is anything useful in the logcat, but the one thing I noticed that seemed interesting was D/StatusBar.NetworkController( 2598): updateIconSet, voice network type is: 13/LTE, data network type is: 13/LTETo me, this looks like I might be seeing issues with some failed attempt to use voice over lte (as this phone supports it).

used to be on 2.3.4 if I turn off backround data some applications can't work such as market,gmail,gtalk...etc. it's good for battery and performance of phone it be come more battery friendly
now on ICS backround Data always Enabled even disabled from switch on menu but all services still works on play(market),gtalk,gmail...etc if backround data enable/disable switch menu is useless on android4 why still there
4.0.3 and 4.0.4 roms are infected clean install or repair system doesn't work on that

I've had the sony ericsson xperia play for a while, with not problems, however for the last weeks or so it has been us randomly restarting throughout the day.
this only happens when I have enabled the data under "mobile networks". I have not got any battery savers/app killers etc. Ive only got the stock apps that came with the phone and a couple of games like fifa 12

In the older versions the data enabled/disabled icon disappeared every time I cleaned the notifications on the status bar, but after updating to ICS it's stuck. Only changes from enbled to disabled, and touching on it opens the settings, but there aren't any options to turn it off or hide it. Or I'm missing the option somewhere?

I have noticed an issue with the Galaxy S5 that apparently only occurs with the Verizon variant. I work for a place called Wireless Advocates, we are the cell phone kiosk inside of Costco. I'm asking about this because I've had three customers come in to ask about this background data issue.
I'm not sure what triggers this issue but when I try opening up google play I get the "Background Data Disabled : Google Play Store Needs background data to be Enabled" error. It then gives you the ability to either quit or enable the data. If you press enable it takes you to the account screen in settings.
When I go to Data usage the option to "restrict background data" is greyed out. You can't even select it and it isn't checkmarked either. Just to clarify, accessing the internet and other things on the phone work perfectly fine. It's just the use of Google Play that is having issues. I called Samsung customer care and they aren't aware of this issue at all. Also note that force stopping google play, play services, removing the google accounts and adding them back and rebooting the phone haven't solved it. After the reboot the phone will appear fine and then a box that says "Restricting background data".

I have set my e-mail account on my E72.Up until yesterday, the packet data connection was always on (the "3G" arrows logo was always on the upper-left corner), and new messages/updates were syncing on "real-time".Yesterday suddenly, the connection stopped, and now in order to retrieve new messages, I need to connect manually - and yet, after the sync process ends, it disconnect automatically.How can I set back the permanent connection?

I have been monitoring my E75 for a while now (>2 months), and it seems with the firmware 202.12.01, the ongoing call (conversation) will get drops whenever there is mysterious 3.5G data connectivity in the background. I have checked all the settings available and has set to 'always ask' before connecting to ISP 3/3.5G data connection. I am unable to determine which application is the culprit for the connectivity whenever it occurs. All I can see under connection wizard is that there is 3/3.5G data connection with traffic growing whenever there is a call drop. As there is no newer firmware than 202.12.01, wondering if anyone else is experiencing similar issue.

If you hold a Bold, Eris, etc they don't LOSE ALL DATA connectivity like the iPhone 4 does.It is a design flaw and all the smoke and mirrors is total ********.

my data connectivity very often turns off and won't turn on again by itself. For example when I wake up in the morning, I see the WiFi symbol and the network connectivity symbol. The data symbol in the middle (H+, E or G) is missing. It sometimes won't turn on all day unless I switch the airplane mode on and off.

My Maxx does not reconnect to 3 or 4G after using WIFI. When I toggle off wifi the 4G bars are white and I get a no connectivity message when trying to get e-mail. Then I restart the phone and all is good.

Ever since I upgraded to iOS4.0, my iphone 3GS has been losing its internet connection over 3G.The 3G indicator remains lit on the display, however when trying to surf or use an app that requires internet, it simply times out. In order to get my internet back I need to reboot the phone, or switch airplane mode on, then off.It seems to occur after I leave the house, so it may be that the phone is having trouble automatically switching from Wifi to 3G.Does anyone have any suggestions on how to fix the issue?

i have not been able to get a data connection all day. i lost my data connection near my house this morning right on the border of 4g/3g area. i drove to work about 25 miles away where there is 3g only and still have not been able to establish a data connection. i have rebooted the phone, pulled the battery, rebooted in safe mode, switched to cdma only, switched on an off airplane mode countless times and still have no data connection. i do have a 3g icon with almost 4 bars in the status bar, but no connection. browser not connecting, no facebook, no Internet...nothing.

I am having an awful time loosing cellular data - can't send or receive text messages, use Safari or Find my Friends etc. I came into the forums looking for help and found posts about the personal hotspot constantly spinning. I looked at mine and it was too. I did a hard reset and it finally stopped. Immediately I got connectivity back. I don't know if that is causing my loosing internet or not but it seems coincidence that when it stopped spinning I got it back.Simply going into and out of airplane mode and toggling cellular data on and off never restores connectivity. Often it will restore when I leave the building. But I have 3-4 bars of signal and 4G listed as available when I'm inside.Also, something is chewing up my battery. I was at 100% when I left the house at 8 am and at 65% at 10 am with the phone sitting on the desk doing nothing.

iPhone 4S, iOS 5.1.1

I'm in Ontario Canada. I'm wondering why I can't access the web page where my webmail is located.The screen says, "Data connectivity problem. A secure connection could not be established".Does this mean I will not be able to access my persona.ca emails on ths device?

According to this Motorola FAQ about their Android encryption, "When SD card encryption is enabled, all new files added to the removable memory will be encrypted. Files stored on the card will not be readable via another phone or card reader connected to PC. User can transfer files from encrypted SD card to PC using embedded Phone Portal application." So what happens if a user encrypts their data and their phone dies? They will not have the opportunity to transfer it to a PC and the replacement phone will have a different ESN. Is their data recoverable via any other mechanism or is it lost forever?

Just got the new Bold 9650. Should I have the firewall enabled, and the encryption enabled? What else should I do to make sure that my phone is secure?

I have a problem with calls on my Z3 dual and the Answering Machine after the update to L.I don't have Smart Answer enabled -gesture to answer calls- but when I answer a call too close to the time set to the Answering Machine to kick in, when the call reaches this time (say 25 seconds) the call will be interrupted for about 2 to 5 seconds where I can't hear the other party and they can't hear me, and then the call will resume.If I disasble the answering machine, this bug is gone.I have cleared data of the phone app but still this issue persists.

Out of the blue my phone is not connetcting to my office wifi. It keeps showing that the network is out of range even when my ipod and all of my colleagues are able to get a clear and strong connection. I had updated my phone to ICS a few days back. Could it be because of this?

I was having GB version of android on my Xperia Pro. I am using X-plore file manager. When I tried to go to root enabled setting from settings menu of the app. the app said root access disabled and I was never able to get root access. Yesterday I updated to ICS from PC Companion and my app. was already there on my memory card. When I opened the app I was able to go to root folder and the app. haven't said that the root access is disabled. I disabled root enabled setting from settings menu of the app. but I am worrying about wheather any other app. that I install can change my root (default) files. Also my phone is in warranty and it is said that warranty will void if you root your phone. But I have updated my phone through PC Companion and just want to confirm that my warranty won't void.

This message "Call Forward Conditional is enabled" appears everytime when making a phone call (screenshot attached).
Looks like it is related to the setting here: Settings > Call Settings > Call Forwarding > "Forward when busy" or "Forward when unanswered" or "Forward when uncreachable." I have them set to carrier's voicemail #.
