Hi all,
A few days ago I noticed my data connection lags and it takes a while until tha up and down arrow start blinking under the H indicator.
Sometimes it is fine.
Also several times I noticed in an are with 4 bars my connection would drop completely, shie no bars and show a little x instead and then a minute or two later it would come back. Tried factory reset, did not help...
Does anybody know what is going on?
I have done the true perma root and unlock as posted in the development sticky.
I also removed some bloatware which do not come back when I do a factory restore. Not sure if that matters though or of it is related.

Are you running the stock rom? I'm guessing so. If you went through and deleted a bunch of stuff you very easily could have deleted something you didn't want to.
I would suggest grabbing the stock nandroid restore from the thread in the development section and going back to a clean install. See if that helps.

im not rooted and i have the same issues. Going from full bars to nothing and then it lights back up. I assume it has something to do with the tower its connected to
Sometimes I only get phone call reception and no data,I call T-Mobile and they say I'm not in a 4g area,but for the past months I've been here and get the 4g full signal..this only happens like twice a month.its a big problem with their towers.

I'm sure it's a radio issue. Happens to mine and my roommates MT4Gs. And since we don't have another radio, we're kind of SOL there.
I've had my mt4g since they dropped, and it's only started doing this to me recently... when it happens, I go to the APN's and reset to default... it seeeeeeeeems to work (for a short time), but then it goes right back to sucking...
You can also just toggle airplane mode. Will bring speeds back up for a short time.

One day all of a sudden as i was running cm9 alpha 5 my data went away. The h or 4g icon flashes and disappears in half a second. Ive tryed fresh flashing cm9 alpha 5/6 and MikMIUI data doesnt work on any of those. Wifi works but i need my 4g connection for when im out of range of a router.
Ive tryed a couple of sense roms and the data works there (mik XE, miktouch, virtuous infinity, primadona) but i cant get it working on senseless roms /: .
Im not the biggest fan of sense can somebody help please?

This is a commonly reported issue with CM9 A5/6. MikMIUI is based on CM9 and so has some of the same issues. Time will tell if it is insurmountable.
Hastily spouted for your befuddlement
So basically im not the only one having issues with data. Is there anyway around this?
Also my data was working fine on cm9 alpha 5 for a month until about 3 days ago.
I really want to run miui because of the extensive customization options but i need my data plan working /:

I had the same problem with CM9 A5 about a month ago. Out of the blue, it just stopped working. Somewhere on these boards, there's mention of changing the APN settings which I did and it fixed the data issue I was having. If I can find it again, I'll post the link.

I tryed it on mikMIUI (love that rom) and i have no data at all. 3 days ago the data icon would flash but now it just never comes on.
Ive tryed reflashing a billion times and redownloading also but i cant get data to work
Sent from my HTC MyTouch 4G Slide using Tapatalk 2
Are you S-On or S-Off? If S-ON, did you flash the boot.img file before flashing a new ROM? When you flashed your new ROM, did you wipe all data along with it? Davlic, user data, etc.? Unfortunately, I don't really know what else to tell you other than to do a nandroid backup, wipe everything off your phone and see what kind of results you get. Once my issue was corrected, I really didn't go any deeper into why it happened and didn't get much of a response when I inquired about it.
Yeah im gonna try that. But yeah i am s-off and when i flash a rom i wipe cache and dalvik and i format system, cache, and data manually.

Finally got it working! All I did was what I used to do every time I installed a rom with a different kernel, mount system and data then install. I'm so happy I got it working and batterylife shouldn't be an issue with mikmiui since my 3800mah battery is coming in today

jeffakajeff in the CM9 alpha thread suggested to reflash the radio. I didn't find a link here on xda, but i didn't look very hard. I did find it on rootzwiki, as it was pinned at the top.
I have this issue. Seemed to crop up every 2-3 days recently, even though i have been running A6 since its release. It progressively got worse until i just completely wiped and restored my device today.
Gonna flash the radio and see if the issue returns.
*edit*
Don't forget to wipe cache/dalvik after flashing radio or it won't boot

what kernel did you use, just curious?
I used the kernel mikmiui comes with. All I did was wipe everything data both caches and then I formatted data cache and system. And before I flashed miui I mounted data and system.
On a side note man this battery makes the phone twice as thick but I think its worth it. I haven't charged it yet and I've only lost 5% with wifi and bluetooth on. Screen times been about 45 minutes

I started having this problem with my phone. I talked to a girl at T-Mobile and she said the SIM card was having issues and replaced it. I had the same problem the next day and went in again. Since I have the insurance plan, she just RMA'd the phone for free, saying it was a problem they've been having with the radio/antenna stuff. The radio would get finger-meltingly hot and flash the H icon on and off and would never get a mobile data connection. I also tried backing the clock speed way down below stock to see if that resolved it.
Well to save battery I ran across a post on Droid Life about an app turns off LTE since we don't have a setting for that. The app is called Phone Info. I was able to switch it to 3G but now I can't get LTE back. I tried to select "LTE/CDMA/EVDO" but it doesn't stick. It keeps going back to "CDMA Auto (PRL). I tried rebooting and even wiping the phone but nothing. Any help guys?

In the phone info, switch it, then select turn radio off, then turn it back on. Has worked for me in the past.

It's been discussed around here pretty extensively but it's an issue with Bean's rom (mb synergy too, I don't know) but once it is switch off lte/cdma/evdo you can't switch it back .
When it happened to me, the only thing that fixed it was nandroiding back to my stock/rooted rom, changing it and then reflashing beans and leaving everything alone.
I just did this today and just switched back to lte with no issues whatsoever it went straight to 4g.
The other night simply I opened this app and lost all data on beans b6...It was as if the app glitched because the screen glitched and bam, data/voice was gone... so I went to device info and the app automatically changed my device to wcdma preferred wtf? I got 3g back by switching to cdma, but still no LTE even after switching to lte/cdma/evdo...
So I ended up having to reprovision my device by dialing: *2767*3855#
This will wipe data so have a nandroid ready, but it should restore LTE...atleast it did for me.

On Beans? It works on stock, but hasn't worked on Beans. mb it got fixed in B7 though.
Similar issue here. I flashed CM10 last night. My 4g worked for about 10 minutes, but it dropped 2 times within 5 minutes, then for good. I rebooted to see if it would come back, no luck. Went back to a restore, same thing. Got phoneinfo and I can get data only on LTE/WCDMA and LTE/GSM/WCDMA. LTE/CDMA/Evdo shows no data, and roaming. Can't seem to get 3g at all. Phone won't even show as activated in CM.
update: Droidstyle's fix seems to have worked. Too scared to play around with the preferred network or CM now though
Avoid jellybomb theme and beans rom if you use the phone info app

Thank you so much. This worked like a charm. I work night shift n this happened to me at work. When I got home, I started to download the stock files to Odin back to stock to fix it but when I seen your suggestion, I did it but I fell asleep waiting for it lol n when I woke up, I got a pleasant surprised. Got my 4G back thanks a lot

even doing the whole reprovision thing has not allowed me to go back to lte/cdma/evdo.. im still stuck at either gsm or cdma auto prl... this is getting really annoying...
Personally i would avoid using that app period, it seems to cause issues on any rom

It's like my radio sleeps sometimes. This screen shot shows no data. Once I wake my phone data reconnects. I don't think this is caused by no signal.
Sent from my SCH-I535 using xda premium
Looks like you live in a so so signal area, the closer it is to green then the greater your signal is. I would think that's an issue with the towers in your area cuz as you know the signal fluctuates often even while sleep.
Sent from my SCH-I535 using xda app-developers app
Thanks. I don't understand why it shows no signal when there was signal. As soon as I woke the phone it reconnected to the tower. There's a delay when it switches from 4g, 3g and 1x....This long area of red was probably the phone stuck in the delay between switching? While trying to submit this post I just lost data in a strong 4G area..... I don't get it.

How often within a day/week does this occur? That's still odd behavior that you lose signal or notice signal degradation while sleeping.
Sent from my SCH-I535 using xda app-developers app
This happens once or twice per day. Seems to happen in areas with less than great signal, that's why I think it is maybe getting stuck in the transition between 3g and 1x. No idea why it stays stuck once I move to an area with better signal.... Seems like the radio is sleeping until I wake the device.

It happened to me before. Try to go to flight/airplane mode and back. It should reset everything. I also sometimes press and hold the home button , then remove all applications and go to ram memory and clear it.

That does work but we should not have to do that in the first place. Hopefully a update will fix the data problems.

Are you stock? if no, what ROM are you running? Are you rooted? what apps are installed.
If you have CWM recovery, i would try to wipe cache and reboot, see if it helps at all?? if you don't have much installed, i would say do a full system restore...
one other thing, are you losing data, ie; not getting text and or phone calls? Also, check to see if you have any battery savers checked. Might be just a method of saving battery by shutting off data until it is needed.

As far as I know I am not missing phone calls or texts. Power saver is turned off. I am basically running the phone the way it came brand new (not many apps, no root, no unlock.... Yet).
Thanks for the replies. Any chance a factory reset would help? My mute/vibrate functions in settings do not mute the phone either... Still get audible notifications and phone rings like normal. Unrelated to the data issue but still weird for a new stock phone.
Sent from my SCH-I535 using xda premium
I'm not going to lie. I don't know if it will help or not. But if you are stock and got nothing to lose it would give it a shot. Can't hurt? Also, as others have said, it sounds ds like it could be because of signal strength. A lot of variables though.

Data wipe did not fix the mute problem. I am very annoyed. Will see how my radio acts today after the wipe.

Now before I say this I want to make it clear that I am not representing Verizon or Samsung in any way with this post, I am just updating the users on what I have identified from the test of my device on this reported issue.... So with that said you can take this accordingly..
Ok everyone about the reported connection issues reported, I recently have been able to duplicate the signaling issue reported on my S3 and it appears to be miner for me at the moment but I can say that it is present.. I recently attempted to isolate the bug and I learned that when I placed it in my test rig to monitor the device in the weakest area in my house the software would temporarily powers down the radio for a few seconds that causes the device to loose all connections (Wifi, Bluetooth, 4G and some times also the network connection), this only happens in a weak connection area and it does appear it could be a software related bug with how the radio drivers handles switching the connection from one connection to another.
From the test results this does not appear to be a hardware issue but I do agree that this could be a pain for a user on the border of a 3G and 4G connection because any connection change causes a crash or radio and force restart.
I have reported this to CS and it appears to be a situation that is being looked into and a solution is possibly in the works... Eventho this isnt a major issue for me at this time, I hope to see a update to address this soon.

This is frustrating. I have lost signal now two times and needed a reboot to get it back. When I did, I was not only losing data, but phone also. I would get this barrage of texts and missed calls.
I am rooted and unlocked, so there in itself could lie a problem, but it comes without warning and the phone appears to be working. Would the SIM card really effect that?

Firmware: CM10.1.2
Recovery: CWM
Notes: Full wipe, cache partition, dalvik cache, erased SD card, etc. Closest thing to a clean slate as possible before flashing.
I flashed CM10.1.2 and then GAPPS and then the new skyrocket radio because I was unable to hold a connection for more than 2 seconds before calls dropped. It was essentially unusable until I upgraded the radio. I don't seem to be missing calls but the poor reception is hurting my battery and the data speeds are very slow. Last I checked, I was without a signal 40% of the time whereas before it was close to 0.
Right now, it pretty much always stays on 4G and 0 bars. Occassionally 1 and then briefly at 2 bars inside and outside. However, whenever I get a call, it immediately switches to H+/3G and then I have full bars. So I'm not really sure what's happening. I also seem to be receiving texts on time without lag.
I've gone in and chosen a network - there are three options for ATT in my area and choosing any one of them doesn't make a difference.
Is there something I'm doing wrong? Any suggestions?
That's what's supposed to happen

That depends on your area and the radio used. I was talking about the switch to 3g when making a call.

Ahh, okay.
I am using the ATT official JB radio. Before I upgraded the radio and the firmware, I had pretty good reception when I was CM10.0 so that's why I'm confused about the reception problems now.
Have you tried the latest Rogers radio?
