Data not working on my wife's phone

My wife flashed her hero to the official sprint 2.1. She had never rooted or flashed a custom rom before, so her going to the official 2.1 didn't really bother me much. However, now she's running into an issue with her data not working. A couple days ago she noticed she wasn't getting her e-mail. Strangely enough, mine quite working too (I'm on fresh 2.1.1). I rebooted my phone and mine started working. So I went to her wireless and network settings and turned off her data. I then turned it back on and after 30 seconds or so it said it was connected and everything started working just fine.
The strange part is there are no errors and even when the phone tries to check e-mail, it doesn't report any errors. Now, on my phone when this happened, my HTC Mail app threw a fit because it couldn't connect to the exchange server. Since I could refresh my gmail account and got no errors I thought it was just our exchange server. I signed into my account on my PC (for exchange) and it was in fact working fine. After I rebooted (just this one time as mentioned above) gmail kicked off with new mail and exchange connected fine.
Today, she has told me 3 times now that she went in and reset the connection (turn it off and back on) and a while later it would quit working again. She turns her phone off every night, but for good measure I am having her reboot it now.
Anyone else have this issue? She never had this problem on 1.5, so I don't think it's hardware. I've only had the issue once, but I'm also not in her area right now (tower related, maybe? My data borked when I was at home where she is at right now).
Thanks

This does seem like a tower problem. However, if you want to troubleshoot, you could always reset your data settings via the Sprint ## codes.
For data, enter this code: ##3282# on your Dial Pad. Give it a second and it'll ask if you want to view or edit your settings. Trouble shooting this problem would mean you have to Edit the settings, but in order to edit them you need your MSL code, which can be obtained by either contacting Sprint CS and asking them for it; or you can search around here on XDA and I'm pretty sure some people posted other ways to get your code.
Once you have your MSL code, choose edit when you get the pop up window and then click on your menu button -- there should be an option for you to choose reset -- enter your MSL code and your phone will reboot.
This may or may not fix your problem; I've had success whenever I've had data problems.

Hey thanks! I did a search for MSL and found a thread with a procedure to get it through CDMA workshop but the drivers don't want to work with Windows 7 x64.
However, my wife was complaining the other day that it takes a long time for her phone to start ringing when someone calls. I think I'll call sprint tonight when I get home and just tell them I need to fix that and see if they give me the MSL... Might kill two birds with one stone.

On the taking a long time to ring:
1) Move the ringtone off the SDcard into the phone, in some cases the SD card is to slow to read it fast enough. - Worked for a buddy of mine
2) There is a polling rate you can set when you get the MSL - but I have heard sprint forces a particular rate from the tower even if the phone has one set. - This will also decrease battery life.

This may be too obvious of an answer, but have you tried using the device self service tool and updating your profile and prl?

No problem, hope everything works out.

I had the same problem, took it to the sprint store (Waste of time!) and ended up hard resetting it, seems to have fixed the problem. you can hard reset by turning off the phone and then holding down the end, back and home buttons and selecting "clear storage" or "clear user data" (sorry, can't remember the exact wording). It will completely reset the software but it will wipe the data off your phone.

I got her MSL code via the logcat method that was just recently posted and reset her data and also changed her slot index. Although some people say that it is overridden at the tower, I also changed her priority. I updated her PRL as well. Before, it was ringing after I would hear about 3.5 rings, sometimes 4 full rings. Now it's ringing on the second ring. Also, her data was essentially turning off after about 30 minutes. After doing all of the above, she is saying it hasn't stopped working yet.
Thanks for all the suggestions, looks like it might be fixed.

Well it's still not fixed. She has it happen a couple times a day and now my phone is doing it too. It's not happening consistently that I can tell, just seems to randomly stop working.
Also, I'm on Fresh 2.1.2 and I'm getting some really really bad lag. I don't use any custom ringtones, just the ones that came with the phone and sometimes my phone will start to ring and the only way I know is because the vibrate starts. Then a good 3 seconds later I'm still getting a black screen as the phone is trying to tell me who it is.
I will randomly pick up my phone to surf the web too and it won't respond or do anything for like a good 10 - 15 seconds. I open up ES Task Manager and usually one of the mail apps is trying to update with like a 5% - 10% cpu usage, but that's all that has any CPU percentage. I'm not really sure what to try next. I've removed some apps that I don't really use and a couple that I just recently installed just to see if they are the culprit.
I'm using the Launcher Pro Beta too. Maybe that's it?

I've had a similar issue... only happened to me a couple of times since the update though... but I've just been turning "airplane" mode on and then off it turns off the radio and then turns it back on... seems to have worked for me...
again.. for me it's only happened a couple of times since the update to 2.1 so it could be a different issue.

I never thought of airplane mode. Doing what her and I are doing just reconnects data, not turning the radio on and off. I'm going to have her try that next and see if that fixes it. She says that she turns the phone off every night, but maybe she isn't some nights.

[Q] No more 1X data after playing in the hidden menus

I was playing around with this and, beyond changing the GPS settings and the navigation volume, I didn't change anything, just browsing.
Well, my phone rebooted a few times while in the ##DATA# section, even though nothing changed (that I am aware of), and now my phone no longer has 1X data, so my data goes away unless I have 3G.
Does anyone know what I may have changed that broke this? I haven't touched any settings in the main phone, as it happened while I was looking around in the secret menus.
Is there a way to restore all of the settings to default if all else fails? I tried doing the *228 option 1 programming, but to no avail. Still no 1X data.
-------------------
UPDATE: For those reading this thread because you have also lost data connectivity, I have solved my issue.
By a recommendation from the IRC channel, I activated a different phone (any phone will do, even a dumb phone), waited a while (I waited a day, just to be safe, but I don't think any delay is needed), then reactivated my Fascinate again. Once I rebooted after activation, the data was all back to normal again. No issues.
Keep in mind, you MUST do a new activation, not simply a *228 opt 1 while the phone is currently activated, as this does not seem to reactivate the data. It must be a new device activation (coming from a different device)
Hope this helps someone avoid the stress I went through.

Bump because this sucks.

Need help from devs!
+1 bump!
This is a serious issue as a result of people releasing the "secret codes" with no explanation of what each menu option does.
I, too, am experiencing intermittent data connectivity as a result of tinkering where I shouldn't have been. The OP and I are not holding anyone liable, but just asking for expert help to get our phones back in original working order. I really don't want to call Verizon, risking this becoming an insurance claim which requires a $150 deductable. I could drop Big Red and get an Epic or Evo with that money (contract is up in a couple weeks).
My problem is that the data connection seems to be going into an on-demand state, but when that demand is present, the connection will drop. If I wake the phone (press the power button to turn on the display and unlock), a 3G connection is present. However, if I try to start browsing the web, for example, the connection will drop completely within 1-2 minutes.
I've tried changing the "Set preferred network type" option (found in *#4636*1111# > Phone Information) to every logical option - WCDMA Preferred, CDMA auto (PRL), CDMA only, EvDO only, etc - to no avail. Looking at this menu right now, the preferred network is set to "Unknown". When I toggle the radio on/off from this screen, the "GSM disconnects" active log takes a few minutes to connect, and I see packet traffic. But, again, when I attempt to use that data connection, it will drop completely in short time. I've done everything I can think of, short of a full Odin restore.
Surely XDA has some cellular experts here - maybe even Verizon network techs - that know how to fix this.

i disagree with your first line. this is a n issua as a result of people who dont know what they are doing. not because it was leaked. if you dont know how to mess with your phones. dont. and if u do and screw up, dont blame anyone but yourself

Thanks for the not helpful reply. Argue in your own thread. I need help, not a finger pointing lecture.
Unless you know what caused my issue, you are just as ignorant as I am. The difference being I didn't climb on a soapbox about it.

I'm in the same boat, lowkee. I'm just frustrated because I've posted this issue in 2 different forums and no one tries to help.
Just like you, I only changed the GPS Startup Mode to "cold" and looked around at other things - I touched nothing else. Last time I checked the GPS setting, it was back to "hot".
My intent was not to start a flame war or hijack your post. I was only trying to explain what I troubleshooting I've done in hopes that it may help you and, more importantly, get a response from someone who knows this topic front to back.
The response I got is the reason why my post count is only 2 (now). These days you can't go into any forum without risking backlash or flaming.
Back to the topic at hand - does anyone have any helpful suggestions for the OP? I'm just going to do a stock Odin restore and read up.

Let me know if that ODIN restore (and which part of it) fixes the issue. I have a suspicion it won't, and if it doesn't, I'm really worried.
Wiping is not an issue; I don't want to have to wipe for no benefit, though. Thanks for being the test subject

Ok. So I actually had to use the "force close loop" restoration method, including manual voodoo removal even though it should have been removed before - I never reapplied it. Data is staying up... nope, just dropped again. I'm really starting to hate this phone.
Here we go again... baseband version is the DI01 update, but build number is DH12. Removing root and going to try OTA update, IF data will stay connected long enough...
That DInc in my desk drawer is starting to look better every day. It's even one of the first batches that had the (AM?)OLED screens AND it has Froyo!

I hate to start typing this, but I believe I've fixed my issue. Here's what I've done so far (in order):
Removed Voodoo lagfix manually.
Wiped System via stock recovery.
Wiped system/cache/Dalvik cache via Clockwork Recovery.
Flashed stock system partition via Odin w/ PIT loaded.
Flashed stock kernel via Odin w/ PIT loaded.
Followed steps from the post "How to Escape the Force Close Loop of Hell" on AndroidCentral forums (sorry, can't post links yet).
Once fresh ROM loaded, installed CWM, fixed permissions & reboot.
Loaded the latest JT stable kernel.
Installed latest JT CleanROM.
And, of course, while I was typing this post, it dropped data connection when browsing the web, but not during the first time setup when Google Sync was processing. Very odd, but I'm now at a point where I feel I can troubleshoot further. Not going to install any unnecessary apps until I get this fixed. The SpeedTest.net app is good to test your connectivity - data immediately drops when I run it.
Also keep in mind that when I say that the data connection drops, I mean the 3G icon itself completely disappears and I get a network error. So back to the drawing board.

This is what i have had to do to correct 99% of all my issues ... results may vary and I base this off my own personal experiences:
To undo any changes that the hidden menu would have changed, I did a "factory data reset" from within the privacy options. Not from clockwork and not from teh original "-Vol and power". Neither clockwork or stock data and cache wipe clean out dbdata. It has to be done within the system options. Those of you not able to add new gmail accounts and super sekr3t phone code problems need to wipe dbdata via this method. Odin backups only restore kernel, recovery and system. dbdata remains untouched and contains these configurations. Ever wonder why after a clockwork wipe, it still remembers your gps options after you selected english and proceeded to configure? Hope this helps.

I'll give that a shot now, but doesn't the manual method to remove voodoo wipe /dbdata?
BTW, I had to perform the wipes from stock and CWM recovery because the system was stuck in a force close loop.
EDIT: So I did the factory data reset from within the OS and as soon as I try to open the browser, the network connection drops off. Time to call CS for a replacement. :-/
OP: As long as you haven't tinkered with funky ROMs or lag fixes, I bet this will solve your problem. Like you said, a wipe can't hurt anything but convenience.

The help doesn't go unappreciated. I've just played with too much experimental stuff, thinking XDA has never let me down. I'm glad you stepped up with a logical suggestion!
Let's just hope this works for the OP.

Thanks guys for trying so many methods. I have a feeling the unreachable phone firmware is storing this data, which means it may not have a reset at all. Some guy in a cubicle somewhere has a document which shows all of those settings.. we need to kidnap that guy.
Seriously, though, this may require a phone replacement if we cannot get someone to tell us what setting controls 1X enabling and tell us the value it needs to be set at.
The conspiracy theorist in me wonders if this was intentionally done by the factory (or Verizon) to detect tampering. Say, you always have to change X value to Y when entering a certain menu or the configuration goes pear shaped. If I were trying to detect phone hackers, this would be my method of detection/prevention. I'm evil like that >

The deductible for an advanced device is $89, not $150

This is beyond awful. Now I don't have 3g OR 1x data. I'm using Wifi right now to make this post.
There must be a way to fix this!

I think its funny that people havent done a FACTORY RESET before posting here. Then they post they don't want to do one because they will lose all their data. Big wow, back it up, do a reset, restore and boom alls good.

[Q] Should I exchange my TF? (wifi issue)

On the 4 networks I have so far connected to, I've noticed the TF will lose internet after being idle for a time. I'm not sure how long it needs to lose the connectivity.
It shows as still connected but the icon is grey instead of blue and I can't access anything on the internet.
In order to fix it, I have to disconnect and reconnect (or go to airplane mode and back), then it works perfectly again.
I have "never" checked in the options on wifi connection.
Is this a hardware issue? Should I exchange it? My window for exchange to BB ends Friday.
Here's hoping for an easy fix that I don't know about

have u reset it to factory? Not sure it would fix it. But worth a try. Before u return it.
* I have seen the wireless go gray. But it comes back to blue bars

Thanks,
I tried that and it didn't work
I returned it to BB for a full refund. Going to go with the Galaxy 10.1.

I'm a bit late with this but,settings,wireless and networks,wifi disconnection policy and then stick it on "Never" which as it say's,will eat your battery quicker but might have solved the issue for you. now all I need to figure out is why I can't connect mine to my HD2's hotspot

I didn't try adjusting Wi-Fi policy and stay with default "Never", and my battery lasts well 2 days with my moderate use (I don't know what a normal battery life on this thing should be), though I haven't tried any movies yet.

i had the same wifi issue but the last OTA update fixed it. it reconnects everytime from idle now

I'm having the same problem, the $100 difference is too big to make me switch. And 3.1 had wifi driver updates, which may be the reason why it has been the problem for me since 3.1.

Software issue
This is well recognized problem.

Samsung Tab A (SM-T285) Wifi constantly disconnecting-reconnecting

Hello Guys, I'm not sure if this is the right forum to ask something like this, so apologies if I'm asking in the wrong place, but I've searched a lot the past days and haven't found a solution yet :/
Less than a week ago, I bought a Samsung Galaxy Tab A6 (SM-T285) 7" LTE, and pretty much since day one, the tablet keeps disconnecting and reconnecting on every wi-fi I tried so far (3-4 different networks). I lose my connection for a couple seconds, causing any app running to lag a bit, then the notification that I have been connected to (the same) wi-fi comes up, and it starts working again. I googled a bit and tried using WPS button, Keep Wifi on during sleep, always allow scanning, even turned flight mode on, but the problem remains. Also, googling usually returned solutions that were aimed towards the router, although I'm pretty sure it's something to do with the tablet, since it's not just on one router. I'm at a loss on how to fix this and the only thing I can compe up with atm is to try a factory reset, which is weird, since the problem was with the tablet literally from the beggining. Any help will be appreciated! Thanks in advance

I haven't really encountered that problem on my device. If you still have problems with the device after factory reset I suggest you try to get a replacement and see if it fixes it. You can also test if the problem goes away if your device is the only one connected to the router or setup a static IP. You can also post a logcat during the interruption so that we can get a better a handle on what is happening.

Try to re-flash your firmware and then install root. There is an application that grasps the Wi-Fi, so it doesn't disconnect and reconnect everytime.

Never mind got it working by using a different browser.
Thanks for posting it, but Samsung's 'solution' [emoji55] is to simply disconnect and reconnect the wifi which I have already tried.
It's related to the device not the network as I don't have any issue with any of my other devices on the same network.
Maybe if they'd release some source code that actually worked I might be able to do something about it instead of them refusing my request.

Mine too. I have the T280, Best Buy has the T350 for $20 more. Has dual band wifi. Might try exchange it, but I rooted it already. Can I go back to stock without them knowing?

I was dealing with this issue although it was never more than an annoyance because it never actually interrupted my wifi connection, it just showed the little toast message that said it reconnected
I somehow magically got the device to stop doing this and I don't know exactly what fixed it, but I think the step that did it was flashing the stock firmware to the device. After that, it never seemed to have the annoying bug again.
The other things that could have done it relate to installing root and using Link2SD to disable some bloatware and moving all user apps to the SD card, but my guess is the fix came from flashing the stock ROM

I have the same problem with SM-T280 (T280XXU0AQA4), tried many wireless network and I have always disconnections. There is a solution for this problem?

Also for me since day 1

I have the exact same issue with my A6 10.1.
Posted about it a while back, I tried a factory reset, i tried clearing the cache. I took it to the service centre who did a complete software rebuild. I reset my router to factory and gave the tablet a static ip address. In the end I got a replacement, the replacement has the exact same issue. A friend bought the tablet the same day I did and has the exact same issue, they also got a replacement, their replacement also has the issue. So that's 4 out of 4.
Samsung couldn't care less, I've called customer service who suggested taking it to the service centre or getting a replacement, both things I've done. I've emailed and received nothing but generic cut and paste replies telling me to factory reset and clear the cache partition. I'm over my 30 days and can't return it. So I have a lovely paper weight and I'm back to using my iPad 3 because it may be slow as anything but at least it stays connected to wifi.

It may not be Samsung's problem but the place where you bought your tablet from. You might have to reflash it to stock (the ODIN way or the Samsung Smart Switch way). Some stores refurbish items and just take the same item repackage after thinking that it is okay to use because they just hook up the tablet to the computer without it actually connecting to the wifi.
If you want to do the ODIN way, you should try going to www.updato.com and find your software and device number and install it. There will be a guide there.
If you want to do the Samsung Smart Switch way, just go download it for the PC and it should tell you how to do it. (YOU NEED YOUR DEVICE NUMBER AND SERIAL NUMBER!)
Or if it still doesn't connect online, it might be because the host file is messed up. It is located in ./system/etc./host
I'm not sure but you should be able to find it through ES File Explorer.

Thanks but I took it to the local service centre who reflashed the firmware and it made no difference. Support told me it's a known software issue but they don't know when or even if a fix will be released.
It connects to the wifi fine, it just drops connection constantly, it shows as connected and I'm sat less then three feet from my router but try streaming or opening play store and it says no connection retry. Then you have to wait until it decides to work again, sometimes that's seconds, sometimes a few minutes. Sometimes you have to manually disconnect and reconnect wifi or turn the device off then back on. Rince and repeat.
I'll download smart switch and give it a go but I don't see it helping to be honest.

Try rooting your device and then check your hosts file and fix it. Sometimes, after when I installed Freedom (In-App purchase hack) it updates the Host file to disable it to connecting to the Internet. It should only say 127.0.0.1 Host, not something like app referrer: 108.xxx.xxx

Thanks but I honest'y can't be bothered with it anymore. As I said myself and a friend got the same tablet, we've both had the same issues, we both got replacements, both the replacements have the exact same issue and I assume it's massively unlikely all 4 tablets have host file issues. I've wasted hours of my life on this (resetting my router to factory for some reason caused my wifi printer to flail which took 4 days to fix). I've not rooted it and haven't installed anything that should mess with the host file.
I may change my mind and give it a go one day when I'm bored. I assume rooting doesn't invalidate the warranty/trip the knox etc?
I ran smart switch last night, backed up, reinstalled the sofrware then restored from backup. Only the backup didn't restore all the app settings, so it removed all the progress on the games I had been playing.

Root does trip your warranty and it is a pain in the but when you are trying to install applications like Oasis's Island app because it knows if you had a "modified" OS. So, you have to be careful on what kind of application you still want to use.
If you can get another replacement or exchange, reset your device and then hand in to the store for a SM-T350 or some other device.
I know that SM-T350's are good for games and other content like watching videos.
Hope I helped and I wish you the best of luck.

The T280/T285 doesn't have knox, so nothing to trip.

Can confirm reflashing stock did not fix it on my t280. Starting to think the only fix is to get a different tablet...

Wifi issues?

Sorry if this has been discussed before. I just can't find it anywhere.
Is anybody having any Wi-Fi issues with their S8? What is happening for me, is that, I connect to my home private Wi-Fi network. Then 10 seconds later the network completely disconnects. Then approximately 10-20 seconds later it reconnects again. It keeps doing it over and over and over, non stop in a cycle. So I completely disconnected from my Wi-Fi, and I'm using my 4G LTE. I started noticing this at home, but then as I go to other to other Wi-Fi networks it's he same issue.
I even did a factory reset to the phone because of this issue and a home button vibration issue, where the vibration would not stop even in standby mode. It was also causing the Android OS settings to even be disabled, and not let me go into the OS serttings from the Android OS taskbar menu button, or the button for the settings in the app drawer. The factory reset did fix the vibration issue, but it didn't fix the Wi-Fi issue at all.
Also, is anybody else having this exact specific Wi-Fi issue I'm having?
Thanks in advance for all the answers and feedback!

You need too update your phone through the Samsung Apps app. Samsung released a fix for the wifi issue.

I already am up to date with all the apps in the Play Store and the Samsung store. I even contacted Samsung, and the woman on the phone on her own just completely connected me to a manager without saying a word to me. The manager ended up saying that he never heard of this and made a bug report so they could look into it. It's also not in their system, according to this manager. This was today around 5PM EST

It could be a hardware issue. Have you thought about exchanging it?

I already did. This is the second device to have the Wi-Fi issue. I just received my replacement device in the mail today around 4PM EST, which is the device I'm talking about here.
The thing I'm thinking is, that maybe if I went back to the direct cell phone providers store and did a buyer's remorse exchange. It could just be a batch of phones that have the same issue. Which more than one from the batch could be located at the same store. But since I'm in Florida, and the replacement device came from somewhere in Pennsylvania it's a completely different batch. Which the Samsung manager agreed with me. He even told me what I already know, that even if Samsung tests the phone. People in the real world using the phone, may encounter issues that Samsung never found on their own. He also went on to say that it's vital, that people in general, especially people that are tech savvy and semi tech savvy call in, because with us calling in it can help fix the issues that Samsung may have never encountered on our own. The manager also said, that there can be more people with the same exact issue, they just never called in and reported it like I have.

What kind of router are you using? Have to tried another? Go to a Starbucks, or some other free WiFi spot and test. So far with you it's been a 100% issue. I'd start looking at different things.

Like I said in one of the above post, that I noticed it at home first. But as I used other Wi-Fi's I noticed it was an ongoing issue. I've tired my home private Network, my work private network, and at a few friends houses.
The manager from Samsung, honestly believes that it is a Android OS bug.

Ah ok. I missed that. Easy to do when on the go. [emoji3]

It's not a big deal, I completely understand. So what else do you think I should try?

I also have issues with Wi-Fi similar to yours, if anyone has a solution, please let me know

Have you made sure that in settings you have a tick on "Keep wifi on durring sleep" ? Also for the sake of it, switch off "battery optimization" for all apps and see how it behaves. Also make sure you swithch​ off the option "smart network switch" under WiFi settings. What your phone is probably doing is constantly trying to switch between the WiFi and mobile data, or the power management puts it in sleep to preserve battery.

Well instead of getting the same same old suggestions (which Im sure you tried, all of them) you can read thru them all here in the thread that already exists:

Honestly what's probably going to happen is, we're going to have to wait for an OTA update.

Keep Wi-Fi on during sleep is activated. But it has nothing to do with that because my phone goes to standby mode in 30 seconds. While as soon as I connect to the Wi-Fi network, 10 seconds later it completely disconnects me. Then 10-20 seconds later it reconnects me. Then it repeats the same thing over and over. The phone can be completely in use, or it can be in standby mode, the same problem still occurs. Also the same thing goes for battery optimization, while it's on and off.
It also appears that someone else on the first page is having similar Wi-Fi issues. So maybe, a few of the many mass produced phones are having Wi-Fi issues. So maybe it's really an OS bug like the manager from Samsung on the phone yesterday was telling me.

Hi All, even am having a same problem, am here in Saudi Arabia and when i spoke to samsung Persons they are not showing an exact root of the problem and not even willing to exchange my mobile. this issue is with my mobile since 3 months and am waiting for upadte , i got 2 updates till now but none solved my wifi problem, i donno what to do

I can say this only happens to me when I have Bluetooth on and my watch connected and when I'm on a 2.4 signal vs a 5....and if by chance is your phone with sprint or verizon?
