I encountered a problem of miss of a mobile network out of the blue. Changeover of a sim card and switching to the 2G-mode, - problems are not solved.
The problem always is resolved only after reboot (on/off flight mode does not help, as well as sim card reconnection),
After reboot the network finds always.
After detailed learning of a problem, was found out, that the network is not disconnected when XT890 is connected USB by cable to PC.
There are also some other alterations the operation of the product XT890:
If you compare it with the normal operating device, on the device which loses a mobile network, the screen is not locked (the sensor control ceases to react to tangencies) after connecting of the charger or USB a cable.
(On this device before appearance of defect and on the second similar device,when it is connected at the charger or connection USB - a cable to PC, the sensor screen does not react to tangencies).
At switch-off of a USB-cable the device there and then starts to search for a GSM-network. Finds, but for a short while. After switching off of the screen and repeated switching-on after 15-20 seconds the network is already disconnected. In a monitoring drawing it is displayed that in sleep-mode networks were not.
Three apparently experienced firmware device
Android 4.1.2 Blur_Version.91.2.26001.XT890.Retail.en.E
Android 4.1.2 Blur_Version.91.2.29001.XT890.Retail.en.G
And even
Android 4.1.2 Blur_Version.91.2.26001.XT890.Vodafone.en.F
with all firmware versions of the radio module
The result does not change.
I ask your help
Can you make calls or receive incoming calls when this happens?

Take or make a call to such a state is impossible. Any operations associated with the mobile network is not available.
However, if the application is running that has already established a connection, disconnect from the mobile network is not happening. For example, the navigator works.
In these times I can take or make a call

I was wondering if there is a way reduce the number of occurances of Windows Live Messenger Mobile (that is built into the ROM) from disconnecting. I am using Wifi and noticed that WLM Mobile keeps disconnecting, even though the Wifi signal strength is strong. Most of the time it does not indicate that it has disconnected and it appears still connected but if someone externally tries to communicate with you, they will see that you have gone offline.
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.

Hello everyone, I know I am totally new to the forum but I assure you that before I wrote this, & before I even joined, I’ve been digging into all WiFi-related problems.
Before I post in this great forum I want to say that I owe all the developers here a BIG thanks, not only for development effort, but also for all help and guidance, it is you guys what make this forum and android community amazing! THANK YOU GUYS !!
The post might look long but I thought describing the issue in one brief post would be better in avoiding doing so in the form of many 2-line posts scattered through a 10-page thread.
Although my WiFi issue seems to me more like a hardware malfunction issue, it seems it’s one of its own where some indicators make me doubt it could be related to software too.
Here what the problem is about:
While I was messaging on WhatsApp, my phone suddenly disconnected from home WiFi & wasn’t able to reconnect anymore at all.
I now can only scan for wireless networks; here is how the problem takes place:
- As soon as I connect to a WiFi network, either it being secured or non-secured, the procedure gets stuck for 10-20 seconds at “Obtaining IP address from (Network ABC)”
- WiFi stays on but then shows “disconnected” or “Unsuccessful”, & (Network ABC) disappears from available networks list (unknown networks doesn’t)
- (Network ABC) reappears –> Device tries connecting to it –> Hangs in obtaining IP –> WiFi turns off
- I turn it on –> Device tries connecting to (Network ABC) –> Fails the same way –> WiFi turns off
- I turn it on –> Hangs completely in “Turning On…”, can’t disable or enable or anything, & got to reboot or battery would drain like crazy!
Things I tried (with no good):
- Resetting my WiFi router (other devices can connect to it)
- Connecting to other private & public routers that other devices normally connect to
- Fix WiFi using market applications: FXR WiFi fix and rescue, and Fix My WiFi
- Wiping cache & Wiping/Factory reset using the built in recovery on device
- Restoring a non-safe system recovery img that was created before the problem started
- Using RSDLite to flash the XT860 5.5.1-112 sbf available at sbf.droid-developers.org
- Safestrap: Wiped cache & dalvik cache, Formatted /system, then Wiped/Factory reset
- Connecting WiFi while on other ROMs (in safe system): CM9, MAVROM 4.5, DarkDroid 1.1, & the rooted deodexed 2.3.6 Motoblur.
Other info & symptoms that may help:
- Mobile hotspot not working in the manner of WiFi: As soon as my laptop or another device tries connecting to my XT860 mobile hotspot, the hotspot disappears from network list on my laptop
- The problem started during my first WiFi usage after the enabling of APN mobile network data
- When I switched on WiFi while Mobile Data was enabled, phone showed a successful connection to my home WiFi ! But stayed for a minute or two, then disconnected, then mobile data would hang & wouldn’t get disabled without a reboot
- WhatsApp chooses random tones when a message is received, even after the many flashes I did (this might sound geeky to mention lol, but it all actually started when I was using WhatsApp, which works using radio)
- GSM network and Bluetooth are working fine
So what do you guys think? What is the chance of it being about the drivers or something?
Or is it totally a hardware defect that grants me a replacement especially that it started while on stock?

Given it survived an rsdlite flash I would lean towards hardware. I know people have had issues with rsdlite not flashing properly, you could confirm by using moto-fastboot to flash the device manually. It's a command line utility, I'm not sure how comfortable you are using terminal commands

Thanks, I'll try the moto-fasboot way..
But what if it is really a hardware defect? I once read that rooting voids warranty, I mean with all what I've tried to solve this, would Motorola still provide a replacement?

Fastboot flashing removes the signs of rooting. Same as RSDLite. It's what they would do for a software issue, it pushes the factory software image.
Lots of people in this forum have gotten replacements after having rooted.

Hello, I got an xperia z three weeks ago and it has always worked perfectly until yesterday: I'm experiencing strange mobile data connection issues. I can surf the web but if I disconnect and connect again, the connection may freeze: the H icon (or g or e..) appears and phone seems to transmit data as it shows an up arrow but the down arrow never appears and I can't surf the web. Toggling data and airplane mode may allow me to connect successfully but it's always pretty random..
I started thinking it was a software issue.. So i flashed The phone with the utility twice.. No success. Carrier issue? Nope: it's all ok and apn settings are ok as I can use them. Hardware issue? Perhaps as I found out that removing the SIM card and inserting it back in a certain way could make the difference (higher rate of successful connections).. So what do you think? Could be the SIM card (I got a new one in December though), the phone or something I did not consider? Sadly I can't test a different SIM now but as soon as I can find one, I will try. Thank you!

Does it happen while your using the device or when it's sleeping you turn device back on? I also have sort the same issue but with WiFi..

Hi.
I've recently started having lots of difficulty when moving out of range of my home's wireless signal in the phone picking up and connecting to the Mobile Data network.
Specifically:
1) Run phone for ages at home using wireless
2) Walk out of house, out of range. Wireless connection goes unconneced
3) Wait for Mobile Network to connect, have at least 3 bars of signal - fails, no E/G/H Sign, Network indicator stays white ( So far waited up to 3 hours)
4) Reboot Phone, instant Mobile Network Connection @ H
Things I have tried:
1) Turning Wireless off before leaving range of wi-fi, sometimes this works ( circa 1 in 20)
2) Turning Phone to Airplane Mode & Back - sometimes this works ( circa 1 in 15 ).
Turning Airplane mode on can take about 4 minutes, as though something is waiting for a closure timeout. Normally, this takes about 5 seconds.
3) Phone calls are intermittant during this time - sometimes I can make them, sometimes i can't.
4) While in range, turn phone off/on again so a "clean" boot, then walk out of range. No affect on ability to reconnect.
Check Phone Status under About Phone, the Mobile Network States reports "Not Connected"
It's really annoying, as I want to use the phone to during breakfast to check the latest traffic information and map updates from Google Maps before I leave home, then get in the car and go, not reboot the phone.
Has anyone else suffered a similar problem?
Phone Specifics:
Motorola Razr I XT890
Android 4.1.2 Stock
T-Mobile
Is there some investigative
Thanks!
I've had exactly the same issue on/off for weeks.
Not found a reason/fix for it yet, although I've been loath to do a full wipe with how busy I am atm.

Hmm.
At least we know we are not in the same boat, and a recent forum query on Engagdet highlighted others.
I've tried to capture a bug report to give me some logs to look at, but that's not working at the moment either !
Thinking it might be an "Always On" app related problem such as sykpe or amazon mp3 :S
