[Q] Network Dropping

I just want to check in and see if any other Inspire owners are having this issue:
I have noticed that my phone occasionally drops the network connection and doesn't get it back right away. There are two different flavors of this issue that I have experienced:
1) I was walking my dogs today and the phone suddenly dropped it's connection to AT&T completely. After a few seconds, it reconnected and everything was fine. I was in an area with good coverage and the status bar showed no connection at all.
2) When home, I leave the Wifi on. Earlier today, when I tried to make a call, it simply wouldn't dial out. Then I tried to open a web page and nothing (after turning wifi off). I had to switch airplane mode on and back off to reset the connection. I also received several text messages at once, all of which had been sent hours before (as indicated by the time stamp on the message). It's almost like the phone has an issue swapping back and forth between the carrier connection and the wifi.
Is anyone else experiencing anything like this?

As an update, I noticed that when the wifi is on, there's a check mark under the H+ symbol (rather than the up/down arrows) and when I switch off Wifi, it doesn't go away. During this time, I have no cellular data. Switching airplane mode off and on doesn't seem to work. Sometimes it recovers on its own. Other times, I have to turn the wifi off and on several times.
This is annoying. It seems to be having issues doing the hand-off between Wifi and cellular data. This is really the only issue I have with the phone. Hope they roll out a fix soon.

I had the same problem. I thought it was because I had to add my own APN. (I could not switch my plan around because it was a work SIM). This caused SMS messages to not go out and an overall bad network experience on the phone. I have since returned the phone because I need a reliable network connection and the ability to send/receive SMS messages at all times. Once a fix is found I will be back. I liked the phone alot otherwise.

Are you by any chance using the SIM from another phone? I had the exact same issue yesterday and data did not work for me until I called AT&T and had them update IMEI number from Captivate to Inspire. Hope that helps.

Nope. I made it a point to have them activate it in the AT&T store with a new sim because I had read about people having issues when they transfer their SIM. I also had and iPhone 4 previously, so transferring wasn't really an option. I'm definitely on the right data plan, too.
I left the wifi off all night and it did it to me again today. The check mark shows up under the H and it loses all data connectivity. I'm not sure what is causing this, but I'd love to know if there's some kind of workaround. I have messed with a few options (like the data always on option) and haven't had any luck.

I was using a SIM from another phone. It is the SIM card from my Work phone and I can not change the plan. It does have unlimited text and internet I just cant change it to a 4G plan. I had added the APN that is floating around here and that worked except I was having the same problem as the OP.

Like I said, my issue was very much like yours and OP's and adding cutom APN made no difference until I called AT&T and had them update IMEI on my account. Presto, all problems went away instantly. I understand that it's not an option for you, sorry

have you tried creating a new apn? try creating one using these settings.

Just did this. Thought it might have resolved it at first, but it didn't. Basically, when I put the phone down for a while, it's like the data connection goes to sleep and doesn't wake up. When I turn the screen on, there's no mobile data. Sometimes, the dual arrows are visible under the "H", but only the up arrow is lit. Other times, the check mark (meaning no data) shows up under th "H" and stays there. Switching Airplane mode off and on will reset the connection.
I hate to say it, but the phone may have to go back. I love everything else about the phone, but this bug is too major to wait for an update or fix. What good is smartphone that doesn't get data reliably?

are you running the stock rom? i haven't been using that rom much so it may behave differently than the custom roms.
i don't think its a common bug. i would see if you can get a replacement phone.

Definitely stock rom. No rooting or anything. I didn't notice this on the first day I had the phone because it was on Wifi almost all the time. I turned wifi off to test it and the issue persists. I suppose I should try resetting the phone first, though I'm not looking forward to setting it back up again. After that, I'll take it into AT&T. I'd love to keep the phone. Can't believe no one else is having this issue.

yeah, resetting it up is a pain. sorry, and i hope you get it fixed.

Just to say it again. I had the exact same problem as the OP. Maybe we both had a flaky phone?

Okay, turns out there's an issue with the AT&T tower closest to my house. I found out from a rep at AT&T. I haven't left home much at all this weekend, so I had no standard for comparison. I just verified it by turning the wifi off on my iPad and using 3G data. It has the same issue.
Of course, I had already done a factory reset and gone to the AT&T device support center, but at least my phone is fine.
As a side note: I love that Android restores your apps now. I always thought WebOS was awesome for doing that and that was what frustrated me most about Android, with as often as I swap phones.

Wow... Wish this was my problem. I switched back to my Palm Pre+ and my data works fine.

Some issues with the infuse

I have been going round and round with att on this issue. My infuse will bounce between hsdpa and umts signal every 30 seconds no matter where i am. They believed the issue was with the phone and replaced it issue still happening. Then advised that it was a network issue and opened a ticket with the "network department" who advised there were no issues in the area. They then removed and re added my data plan with the issue still occurring. Any ideas would be greatly appreciated

It's normal to be connected UMTS. You will only get HSPA when you are actively streaming data up or down.

Is that issue causing data connectivity issues?? On my first Infuse it would show me with 3-5 bars of signal, but when I tried accessing data on apps like the Market, Facebook, or stock Web Browser it wouldn't connect and would give me an error instead. AT&T doesn't know why that was happening. They eventually told me to exchange my phone.

It is and i get the same error it says network unavailable. This is the second "4g" phone this is occurring on

Wow, I had the Atrix and that was happening to me with it as well. I don't remember if it went away after I updated the firmware on it, but I had other minor issues with it as well so I returned it and got the Infuse.
I've been trying out my 2nd Infuse and it seems that it doesn't have network connectivity issues like my prior Infuse, but I've noticed it does start acting up when I use the stock web browser. Maybe the whole issue is being caused by the browser!

I am taking mine back today it cant sit on HSPA+ for more then 30 seconds at a time and this is where a cell tower is almost next to my house and i can see it.

I've been streaming on Pandora for 2 or 3 hours without an issue. My network type switches between UMTS and HSDPA constantly, is that normal?

After working with tech support they feel it is an issue with the phone as it is not locking on to a tower signal. I was also informed that it not a common issue but has been seen with a few of the infuses sounds like a bad batch of phones may be floating around

Man that sucks!! I started having network issues with my 2nd Infuse last night. Today I tried searching the Market and it just kept loading till it eventually gave me an error! I guess Best Buy has the bad batch. What sucks is that the rep at Best Buy almost gave me a hard time when I told her I wanted to exchange it due to network issues.

Spoke to AT&T again and the rep told me that the update isn't for any network issues and that she hasn't heard of any problems with the Infuse so she advised me to either get another Infuse or return it and get some other phone.

Hello,
I'm a new android user and I got the Infuse today. After reading this thread, I tried to see if my Infuse was having the same problem. I noticed when I'm not using data, it goes in to UMTS. However, if I start browsing then it'll go to HSDPA, would this be considered normal or defective?

Not sure if that makes it defective but it happens on mine. Does it have issues loading websites?? Every once in a while when I search for something on google or enter another website my phone won't even load the site and when that happens I try an app that uses internet, Market or FB, and it won't load and finally give a connection error. AT&T doesn't know what causes it.

Congrats on getting the Infuse and moving to Android!
You're really lucky to start your Android experience with such a great device.
Switching from UMTS to HSDPA is totally normal. The battery would die very quickly if the radio had to maintain a constant HSDPA connection. The default is UMTS, and when transferring large amounts of data, the phone should automatically switch to HSDPA.

I haven't had that problem yet, but I've really mostly been using wifi to surf, but I guess I should stop so I can figure out if my device is defective. I'll let you know if I have any issues.

As an experiment, try downloading the app "Net Ping" from the market and set it up to ping every 3 seconds or so in the background. Now if you check your status, it should maintain a constant HSDPA connection.
Hmm...now I'm wondering just how quickly the battery will die? Time to find out.

[Q] Can't make or receive calls

Started a couple days ago, using straight talk AT&T sim on my nexus 5, Data and text messages work fine, but whenever I try and make a phone call the signal drops completely and calls won't connect. People been telling me when they try to call it goes straight to voicemail. I'm running stock rom. Any suggestions? Straight talk and Google both with no help.

Have you tried a different sim card from like a friends phone to make sure its not the phone itself? You can also try to call ATT to see if its on their end.

Swapped sims with my wife. Mine worked on her phone hers didn't on mine. Think it might be a hardware issue on my phone and I got it on Craigslist so I think I'm screwed

Sounds like it definitely is a hardware issue now or something with the Sim tray. Sorry to break it to ya. Hopefully you can work something out with the guy on Craigslist.
Sent from my Nexus 5 using XDA Premium 4 mobile app

Thanks. I have had the phone for about 4 months with no issues. I K of its not the sim tray because I still get data and texts and I can receive calls sometimes if I have dull reception somewhere. It just started all of a sudden, pretty frustrating

I just the same issue today as you. It was a ROM issue. I was on PA. I switched to aokp for now.

I had this issue on the stock, unrooted ROM after about 4 months as well. I think the cache partition was corrupted. You can try wiping this in recovery and see if the problem fixes itself.
I didn't think of just wiping the cache, so instead I did a factory reset by unlocking the bootloader and everything cleared up.
Now I wipe the cache partition roughly once a month and the phone runs like a champ. Also I use sdmaid to clear the device from junk that accumulates over time.

Thanks for the help, but I already did a factory reset with no success. Data works fine on LTE but if ibtryvswitching to 3g or 2g signal drops as well. If I have full signal it will connect but anything in less it doesn't connect the calls.

Flash factory images then.
Sent from my Nexus 5 using Tapatalk

This happened to me on my non rooted N5 with 4.4.4. Disabling Wifi and/or LTE sometimes allowed a single SMS to get through, but then the problem resumed.
I fixed it by booting into recovery and wiping the cache partition. For some reason that took a long time (about 5 minutes) but eventually it finished and when I rebooted it was all good.

I'd try the wiping the cache and reflashing the radio.
I had a similar issue first week of owning the phone any time I sent a text I lost service until I rebooted.
From what I've read some N5's don't like the 4.4.4 radios. Mine likes 4.4.4 but couldn't pick up a signal if it had a 50ft antenna with 4.4.3 radio.

I just had this almost exact same scenario. I started having problems with signal dropping using CM12 nightlies (late April 2015) then eventually I switched over to a NET10 because T mobile was not cutting it to begin with. After the problem persisted on an ATT Sim card with NET10, I started flashing different ROMs. Signal seemed to be more stable and everything was fine for a while. After a few days I was no longer able to make or receive calls.
Eventually I did a complete factory image (still didn't work)
Flashed a 4.4 radio image (didn't work immediately, but the next morning it seems to be working as of now)
I probably could have skipped the hours of trouble shooting if I would have (found this thread first) and just tried flashing different radio images. Or maybe it was the series of other steps combined...not really sure.
Good luck and hopefully this helps the next person going through this mess. Oh and don't event waste your time calling NET10/Straighttalk customer service.
*EDIT* Above did not solve my problem, I actually had to fix the physical radio connections which came loose.

same problem
Hey guys having the exact same issue. Dropped my phone hard and then all of a sudden I cannot make or receive ant calls with my carrier dialer. I can send and receive texts, use LTE data , Wi-Fi. When I place a call, it is silent for about 10 seconds then drops the call. When people call it is silent for 15 seconds, then voicemail.
Called google, said it is out of warranty and LG would have to repair it for $150 just to see the phone.
Have done a cache wipe and factory reset. Is this most likely a hardware issue that I need to open the back for ? Little bit of a tech noob but can work my way around things. Any help is super appreciated as I love my N5 32G and don't have the money.

Same issue that I had, just remove the back and reattach/secure the radio wiring. It's on the left side and rubs parallel to the battery. It was a petty quick and easy fix.

So I took the back off and looked at the cables and they were both connected. I took them off anyways and reconnected them. Didn't see anything surprising to my eyes at least. The only thing I did find out was that LTE is the only setting that I can't use data and texts on. 3G and 2G say no cellular network detected. Do I maybe need to replace the antenna cables ??

Hmmm. I don't think the cables would be bad. I would just make absolute sure that they are staying attached after you re-assemble your phone. I even put a small piece of tape over the end that I noticed was loose. If that doesn't work then I think we had different issues with the same symptoms.

I'm having this same issue. Three weeks now, unable to make or receive calls. SMS and data work fine. Wifi works. LTE works. When I switch to 3G or 2G there is no connection and T-Mobile doesn't appear in the list of networks. The SIM card works fine in another phone so it must be an issue with the device.
Tried everything on the software and settings side, flashed different ROMs, flashed different radios including stock. No change whatsoever. I completely disassembled and reassembled the phone. Nothing was loose or looked broken, all contacts seem to be making contact.
I do vaguely recall dropping the phone recently, so I guess that must have been it. The only other possible cause was that Google Play Services was auto-updated the day before I noticed the problem. Of course that is unlikely to be the cause but just mentioning it in case anyone else had this issue starting around Oct 23, 2015.
As much as I hate to do it, I guess I'll have to get a new phone. Just no other solution I can see unfortunately.
For anyone finding this posting through Google, currently there is no VoLTE (Voice over LTE) support in the Nexus 5 on T-Mobile. If that is available when you're reading this, then you might look into enabling VoLTE and seeing if you can make voice calls using that. Based on my reading it seems like VoLTE is a software update (perhaps requiring the provider to support the device as well), but the consensus seems to be that VoLTE on Nexus 5 on T-Mobile is unlikely to happen. But they support it on the Nexus 6, so maybe there is some way it can be done on the Nexus 5. Also Wifi Calling on T-Mobile is not available for the Nexus 5. The consensus there is that the stock Google/T-Mobile ROMs are unlikely to ever add Wifi Calling support for the Nexus 5, but perhaps CM 13 or Android Marshmallow do or will have Wifi Calling support built in, so there may be some possibility of getting Wifi Calling using those.

Did you try checking the cell antenna? That was my issue, I just tapped it back in place and my N5 has been fine ever since.

If you mean the ones with the long wires, then yes, I checked those. Actually I checked pretty much everything inside the phone. According to this excellent disassembly video: youtube dot com/watch?v=OPuCmfhzgbg , there are lots of antennas and antenna contacts. So many that he doesn't get to all of them until 20 minutes into the video. But still, I checked all of those and they looked ok. There must be some damage somewhere, just too small for me to spot. He also identifies "external test ports" for some of the antennas. I don't know how those are used or if they would be useful to debug this issue, but for anyone else experiencing this, you might try looking into those.

[Q] Mate7 4g data problem

Hi all,
I've had this great phone MT7-L09 (softare version L09V100R001C00B127) since last December. My problem is that every now and then the 4g cuts off for a period of ten seconds.
It does not matter how strong the signal is nor which or whatever app I'm using. It just loses network. First thing I did was to change the old sim card to a new one. Did not help.
I was in contact with the Huawei support and conclusion was to send phone to service. OK. It came back with the same problem altough they changed the circuit board...so obviously they though that this would solve the problem. I did not. After messing around with it, trying to find if someone else was suffering with the same problem, with no luck, I send it back to service. Now they said that there is nothing wrong with it, but the problem is still there.
I havent noticed anything cut offs using 3g. It's not a major thing but it would be nice to know if its a firmware or any other software related problem.
If I use Netflix or similar where the data keeps coming it works just fine or if I use the phone as Wi-Fi hotspot, no problems.
It just loses network connection using apps like play store, facebook, whatsapp, twitter, every browser ie. firefox, build in browser, chrome, to name a few.
Should I just keep using it as it is or keep sending it back to service until they fix this issue???
Thanks

Sorry...one stupid question: have you already tried keeping the phone completely stock (without any application and/or software or any kin dof personalisation) for a couple of week and see if the problem still exists?
It really seems to me a software problem. Very strange.

I had the same problem with my MT7-TL10 golden version. For a week or so, the network used to come and go. Then ultimately the sim was not recognized at all. I sent it to Huawei service center and they told me that the sim slot is broken and I had to pay for replacement of the board which I refused. I was sure that I didn't break it. Now I am using my phone with one sim only.

I'm not sure, but isn't the sim card slot located on the circuit board??? If it is, it cannot be the problem, but I must try the second slot anyhow.

I was in contact with the Huawei support and conclusion was to send phone to service. OK. It came back with the same problem altough they changed the circuit board...so obviously they though that this would solve the problem. I did not. After messing around with it, trying to find if someone else was suffering with the same problem, with no luck, I send it back to service. Now they said that there is nothing wrong with it, but the problem is still there.
I havent noticed anything cut offs using 3g. It's not a major thing but it would be nice to know if its a firmware or any other software related problem.
If I use Netflix or similar where the data keeps coming it works just fine or if I use the phone as Wi-Fi hotspot, no problems.
It just loses network connection using apps like play store, facebook, whatsapp, twitter, every browser ie. firefox, build in browser, chrome, to name a few.
Should I just keep using it as it is or keep sending it back to service until they fix this issue???
Thanks

Man why everybody blames PHONE first??? like not trusting !
To fix this problem is to go to networks and u have to restore your apn to default it like refreshes then you can either just turn off data and then on and restart phone

Does not work, same problem after a numerous resettings. If I may add, I've have couple of other phones of which this problem does not occur.
In same place and conditions these phones work just fine not losing the data connection. Sure, if 4g is not available they use 3g, but never ever will the connection break off.

faulty 4G module tuner.. phone ... replacement needed...

change preferred network
Go to settings and -->mobile networks-->>preferred network and select "WCDMA only"..
It will fix your problem..

There is no such option in my phone settings, only the option to choose automatic 4g3g2g or automatic 3g2g or 2g, 3g only and 2g only. As previously stated no data loss nor connectivity issues using 3g. It's bit annoying sometimes when phone loses data connection altogether although signal is very strong. Just waiting lollipop upgrade if it'd solve the problem, I doubt it but...

network operator..
I think it's network problem..please contact your network operator..4g network have connection problem from some local area signal towers..so you just put other network company SIM card in your local area..(use 4g supported SIM only)

Thanks for your advice, but I don't think that it's SIM card problem because there is no problem what so ever using my other phone SGS5.

sorry

Hmmm. Sorry friend..I am helpless.. anyway continue your thread here..in Xda have brilliant members..they can help you..best of luck.

Thanks, I totally missed your comment...this is turning out to be quite a puzzle. I've noticed the less battery (<60%) I've have on the phone there seems to be nothing wrong with the 4g connection. ???

To answer to myself, I was too optimistic...nothing to do with battery. It's just so weird that phone works like a charm most of time and then suddenly not. I'm confused...

Now on the newest firmware lollipop 5.1 it fixed my lte problem

same issue
I bought mate 7 a couple of days ago and I keep losing the data connection. the network gets connected and lost again.
i did everything to fix it but no luck. changed sim, restored device, modified APN and no luck.
it keeps disconnecting seems that it is a problem with the phone itself as i have read the same issue on a couple of forums..
hope it is a software issue and get fixed soon as this is annoying.

In service they replaced my phone to a new one mostly because of this problem and I can say it did not help at all. Only upgrading to lollipop will fix the problem ( tested on beta) I'm on b145 now and it does that all the time. I guess it is carrier based problem not SIM nor hardware.

One Plus One unable to connect to wind network

Hey I have had my one plus one for a little under a year and after a 2 week road trip it has stopped being able to connect and detect the Wind home network. During this road trip I was on airplane mode for the full duration of the 2 weeks with the 05Q caulkin rom installed. Once I had reached my home town of ontario I had noticed that I could only connect to wind away on my opo. When scanning manually for the WIND home network it would appear with the simcard symbol beside it but when trying to connect it would state that it was unable to connect to the network. Although randomly throughout the day it would connect without warning until I rebooted my device where it would lose connection again. I then later updated my phone to the latest OTA which is cm12.1 hoping that the problem would be fixed but to no avail. At first it was the same issue where it would show the WIND network with the sim card symbol beside it but now I am not even able to see the WIND home network and can only able to see the Wind away network. I have tried changing my APNs and have tested my sim card on my sisters opo where it works perfectly fine. I have also done a factory reset and nothing has been able to fix the issue. I would like to fix this issue and anything would be of help.

Did you have any luck yet? Mine is still acting the same. I have been using my LG G2 for a while so I haven't really tried to solve the issue as I tried a lot previously as stated in my post.

Maybe you could post your solution here to help other members that may have the same problem ?

Have found found a solution yet? I have the same problem. Sim card works perfect on OnePlus X, Nexus 4, but not on OnePlus One. I get connected to Wind Away, and I've tried just about every fix including entering in everything manually.

did anyone figure out a solution? im having this problem right now

Wow... sounds like I wrote this thread - aside from minor details this is EXACTLY the problem I am having. My vacation was also two weeks and the randomly connect during daytime but loses connection once restarts sound all too familiar. After Wind store clerk did sim swap, new error msg appears and said "your sim card does not allow connection to this network", so the problem actually got worse. Eventually I had to switch carrier (to Koodo and it works).
No, I have not fixed it yet.
But I'm contemplating to try manual selection of radio band (in the *#*#4636#*#* menu), because mine is showing EURO BAND and USA BANDas choices. Tho haven't made up my mind yet because that might do much more damage than good, based on some Google research so far... frustrating.
