[Q] signal issues on jelly bean

ive been using jelly bean and just recently my 3g signal just disappears randomly on verizon.
does anyone have a link to a good cdma(verizon) radio for jelly bean?

All of the JB ROMs are just using 4.0.4 radios. Sounds like you have some other problems.

I'm sprint and it does same thing for me. Yesterday in a three hour time frame I was disconnected from network 36% of the time. i think was even higher today. I keep checking the stats and no improvement really.

I don't think I've had over two bars since flashed over and I get excited about those. I think I read in another thread (but could be wrong have been googling) and I think it's because we are a port and still have some ics features..? Don't quote me on that tho.

Any help with this would be highly appreciated. Just bought a gnex from someone and I only really get a signal at home. I have pretty much no service anywhere that I used to have service with my Amaze with no problems before. I was hoping changing to jb might help but nothing.

Did you try to prl before you flashed over and was everything updated first?
*Android is upgrading...*

No, something happened to me too when I tried JB (VZW GNex)
I'm in the same boat (VZW GNex).
My stock 4.0.2 reception was "OK", not great. Same with stock 4.0.4 OTA update. Same after rooting. Same after CM9.
Then I tried jdkoreclipse 2.1 JB, and added the "Wi-Fi fix". Everything fine for a couple of days, then reception SUCKED -- empty triangle instead of bars. Toggling between "CDMA + LTE", "LTE only", and "CDMA only" made no difference.
I Reverted back to my prior CM9 image -- still bad, but I could get a signal outdoors sometimes, in a stronger area (sometimes it would help to turn Wi-Fi off). I re-flashed the proper radios -- no material difference.
I can't get any VZW signal at all inside my house or in the yard, inside my office or outdoors in front of it, inside or outside a Target store (all in an urban area -- some other outdoor areas I could get a stronger signal).
Last night I tried Razor's JB 2.6 -- same problem. Everything's working great on JB, (with the exception that my phone is not actually usable as a phone in many areas of the city). People complain that they have to leave messages that I have to retrieve from Google Voice over Wi-Fi, then I return the call on a land line. I tried "re-seating" my SIM card too.
It definitely appears to me as if something happened a couple of days after I first tried JB, that tanked my VZW reception, even after I reverted back to a prior saved ICS image, and re-flashing the 4.0.4 radios in ICS did not help. Every so often, I'll get a good signal outdoors, but I can't count on it.

I had better reception on ics also. I wonder if there will be a radio update when they finally do the full release
*Android is upgrading...*

One other thing that may be diagnostic
I don't know if this might make a difference, but somewhere along the way, Titanium Backup Pro reported that it detected a change in my Android device ID, and offered to revert it. At first I didn't revert it, but as I had more problems, I went ahead and reverted it as recommended. That was some time ago, and it did not happen again. Since the first JB versions originally came off of a Google I/O nandroid, is it possible that the one I loaded retained the Android device number from the source device, and maybe that played a role? Like I said, I reverted the ID AND later reverted to a prior saved ROM.
@ Jedininjafication, I noticed that you asked jacktrck if he "tried to prl before . . . ." I did a lot of things before I flashed, but I have to admit that I don't know what "prl" stands for. Maybe I did it, but I don't know. I can't think of anything that "prl" would stand for.

Just so we're clear, this goes way beyond merely being "inferior" to ICS. We're talking NO SERVICE in a significant part of my city, whereas I used to have service to varying degrees of strength before.

PRL is Preferred Roaming List. It's essentially a list of towers that your phone can use. Keeping it updated avoids your phone looking for towers that don't exist (in the case of a tower being removed) and allows it to "see" any new towers that have been constructed.
On Verizon (and Sprint?), the PRL is automatically updated via the SIM for 4G devices and manually via *228 on 3G devices. On AT&T (unless something has changed in the last few years), it's updated via a star coded call only, though I don't know if AT&T also uses *228 or not.

Sometimes*228 won't connect and you have to do *22804 or *22805 on sprint. There is also a dialer code but you need your msl

Ah, that's slightly different than VZW. For us, we can do *228 and select option 2, or we can dial *22899 (I think that's the one) directly. In the case of the Nexus, it's a moot point (on VZW, at least), since we're updated manually via SIM. Most times attempting to dial *228 will result in the phone refusing to dial.

He could try having them push an update. Sprint has had me do the *#*#4636.... Code and change my network to cdma(prl) then go do the *228.. And that's worked. I had garbage service other day until I did a ping in same dialer code. I don't know if menu is the same on Verizon tho
OH! don't do the SCRTN if your do call them! I did that and since am not stock it completely set my meid and stuff to all zeros and they couldn't figure out how to fix so i had to restore
*Android is upgrading...*

I was having terrible data drops and couldn't find a solution. Turned out to be a faulty radio. Got a replacement and haven't had any issues since. So it does happen I guess.

So, what do you guys think of the Android ID thing? Non-issue? And what would have caused it to change in the first place?

after i did the scrtn thing and everything set to 0000000000 and restored back to a previous version and did the update I haven't really had issues. I do at my house in my room but have been good other than that. I don't even know if Verizon has that menu, but it's the factory data reset code for us. Doesn't reset the other stuff.

i have no idea what happened but this is on 3g. Not wifi. no lte here..I'm second round. Awesome
Android is upgrading...

I was having great 4G signal running any ICS rom, however my signal would drop 4-5 times per hour. I called verizon to see what they could do, as I had read that some people had better luck with a replacement phone or sim card. Verizon first sent me a replacement sim card which made it worse. Next they sent me a replacement phone. The first replacement, which I have no clue how it passed re-certification, because you could see the 3-pin charging area from the front of the phone. The housing was not seated correctly on the phone after they refurbished the phone. So I called verizon back again and I got a second replacement. This one was free of any visual defects that I could see and runs fine on ICS or JB roms.. However I am still getting awful signal where I used to get 3-4 bars 4G all constantly on my original nexus.
If I reboot the phone it locks on the tower at 4G for maybe 1-2 minutes, then drops to 3G full bars, then slowly over the next few minutes drops to 0-1 3G bar(s) and then down to 1X.
I suppose my next move is to get yet another replacement and see if I have any better luck. This is becoming a nightmare.

AT&T drastically reduces your data rates while you make phone calls

I've been with AT&T for years and have in general been quite happy with them. I noticed though that earlier this year AT&T started throttling my data if I was simultaneously on a phone call. This crippling of the data rate makes surfing the web basically impossible if I'm on the phone.
Before people say it's my Samsung GSIII or SIM card, I'd like to highlight that I first noticed this problem on my Sony Ericsson Arc S. One day I could browse the web at 5Mbps download and 3Mbps upload while making a phone call and then suddenly the next day my data was crippled to a crawl (while making calls). Nothing changed with regards to my phone or SIM. And then when I switched to the GSIII and a new SIM card I still have the problem. This is so frustrating and it pisses me off to no end. This link describes what I'm seeing...

Has anyone else had this problem???

well i've found that it reverts from LTE/HSPA to UMTS the second i am in a phone call. but i still get aorund 1mbps (which is good in the part of my work building). UL is attrocious though.

Your results are totally in line with the article I linked said. I copied and pasted here...
"We went from 4.5Mbps download and 1.1Mbps upload off-call, to 1.0Mbps download and .024 (24k)Mbps upload."
The insanely slow upload both you and the article mention will make surfing the web very painful. That's because most communication protocols apply some sort of packet transmission error correction scheme which typically requires data to be uploaded. So even if you have 100Mbps download if your upload is 0.024Mpbs then your browsing experience will be very slow.
So much for talk and surf on AT&T =/

My download is fine, it's in line for this area. Upload suffered.

It's because it swtiches you from LTE to HSPA+.
Still close to 3 mb/s down is MORE than enough to do some quick web browsing while on a call, or downloading an email.

I have a lot of conference calls I participate in where I am not talking the whole time. Being able to browse the web on a 4.8" display is great during those times.

What you said is partially true. The download speed does drop because it switches from LTE to HSDPA+. The upload speed though drops because not because of the switch you mentioned but rather because of the intentional throttling that AT&T has recently put in place.
Have you ever tried browsing the web with such slow upload speeds? I know it's counter intuitive to think that upload speeds are important while browsing the web but in fact the phone is constantly communicating back to the base station so if a severe bottleneck is created on the upload it won't matter how fast the theoretical download is. I've tried this many times and even simple browsing slows down to a crawl if you're on a phone call. Or even worse imagine how it will be if you are tethering the phone to your laptop and then have to hop on a conference call.

There have been many times where I've needed to grab some information from the web while on a call. I get calls from clients and while I'm talking to them, need to pull some information up regarding them. It's better for me to pull it up during the call than to tell them I'll call them back (just so I can pull up their info).

Also, bear in mind, AT&T made it an advertising point that you could talk and surf at the same time, now it's being restricted (in an extreme way).

Yes it's definitely an issue. The download speed tends to stay around 1Mbps while the upload almost disappears completely. What makes it worse is the ping is so high that even that 1Mbps speed, is painfully slow to surf on.

I just got my LTE plan enabled. I notice it today, too that phone switches from LTE to HSPA+.
Well, I haven't tested it if the upload speed is dropping that bad. I am on Rogers, I will report back to see if it's carriers restriction.
I just have a question that why LTE isn't compatible with voice call?? It has to downgrade to HSPA+? It's like totally switching to another network, which is really annoying since the phone always gives the no date connection message during the transition.

One possible explanation is battery drain concerns. Being on the phone greatly increases the discharge rate, as does actively downloading something at lte speeds. Put them together at the same time could be bad for the battery. Just my speculation.

Its called circuit switch fallback att does not have an lte voice network so when you take a call it goes to hspa then 15 seconds after the call it will go back to lte

This! Voice is not carried on the LTE network only data is. When making a phone call you are on HSPA. This has always been the case on the LTE network. Once you complete your phone call your phone (data) revert to LTE.

I get that the phone drops LTE for voice calls but even HSPA has usable upload speeds? 0.1Mbps is a joke.

It doesn't really matter if the download is "fast" because the upload is so slow and the ping time is sooo long that it makes accessing the web basically impossible. AT&T has essentially crippled web access while you're making a call.
Note that this has nothing to do with the fact that AT&T switches your network from LTE to HSPA while on a call. Rather it has to do with AT&T intentionally crippling data rates to a practical standstill while you are on a call. And the reason they do this is to save bandwidth. So yea, the consumers just got shafted.
Also, just to clarify the reason the network switches from LTE to HSPA while on a call is because LTE currently does not support voice. There is an initiative called VoLTE which is Voice over LTE. This will roll out next year. Even then though, there's no guarantee that AT&T will 'un-cripple' the data rate issue we're talking about in this thread.

Tested today at work in a two bar at best 3G area - Still had 1mbps downloads while on a call -

Yea you'll get 1mbps download easy while on a call. The issue is that the upload and ping speeds are insanely slow if you're on a call. That totally ruins any web browsing or email experience. Just try running running a net speed test like 'Speed Test' or something and you'll see.

It must be the area you are in then, because when I'm on a call, I have no internet whatsoever...The icon changes to 4g (from LTE), but opening any webpages timeout after 5 minutes of trying.
Should I contact ATT regarding this?

Sprint gawd! !!!!!!!!!

Just got done talking to sprint over the community and the signal issue many people are having trouble with they said I need to get my phone run through diagnostics for antenna malfunction which I think is b.s. cause my phones are acting up my sister in laws LG Machs are doing the same as well as my friends s5s and s4s so its obviously a problem connected to there towers and the way I see it they need to start getting everything done right otherwise I'm headed to verizon

Opposite here, guess it depends on your area. Mine is better than ever but right before the 4.4 update it was horrid. I think they're trying to overhaul their network now so it might be shaky for a bit.

Sprint is updating its network vision for your area. We're sorry for the inconvenience.
This is all I ever hear out of those outsourced folks from India.
also, in california, my 4g and 3g always alternate depending on which part of town im at. Its rediculous.

Never had the data issues when I was on stock 4.1.2.
For me, a solution that is temporary may be leaving mobile data on, don't turn it off. Power phone off and power on again. Wait for data to connect.
I did that and my data seemed to be stable, but if you turn your data off and leave it off for a while and turn it on again, it'll become unstable again.

My data on kit Kat is better than ever. 4.3 was horrible and 4.1.2 was pretty good
I'll also bet they are doing tower upgrades. Be patient sprint is overall the best.
If you go to Verizon you may have a good signal but it's will cost you about 30% more in cost and you'll constantly have to

When I call customer service I get connected with an office in Shreveport where I speak to Americans. Sorry to inform you that they're typically not any more knowledgeable than the people you're referring to. The good thing is that I get to speak to people at all. When I was on AT&T that was often an incredibly difficult thing to do. The last time I spoke with Sprint's customer service, it was in regards to how horrible my cell signal is at my house. The lady told me that they were indeed updating their system in my area and were expecting it to be 100% completed in the first part of June. I'm waiting to see how that goes before complaining any further.

Hahahaha. Yeah that's the story I've heard for the last 2 years. Sprint LTE is a joke. I regularly get sub 10k speeds with 4G connection. Enter a building and it's back to 1x. Come July I have 2 GS3s for sale and it's buhbye Sprint after 10+ years of broken promises.

Must be location related. I live in the middle of nowhere, in a forest nonetheless, and in my house I get 1 bar of 3G. On my back porch I get 2 bars of LTE, but in town I get full LTE. It's slightly less signal than I got at home on AT&T but then I was paying almost twice as much for only 2 gigs of data. But, I suppose the grass is always greener... :sly:

Just updated to 4.4 and data connection seems to be stable. When I was on 4.3 the past 3 weeks it would shift to 3G a few times but I think Sprint is upgrading our towers. On 4.4 its gone down a few times to 3G but I'm banking on the Towers.

Ive been on 4.4.2 for a few weeks now and my devices ability to hold onto a signal has gone down considerably. Previously I had to roam at my house. (We live in the country) Now a lot of time I have no signal at all! There's nothing to be done about it so I just use wifi and don't worry about it.

My data keeps going from 4GLTE to 3G no matter where I go unless I reboot my phone.

Simultaneous Voice and Data?

Received my note 4 yesterday, noticed today while I was on a call that I could not connect to LTE data simultaneously as I was used to doing on my note 3. This led me to inquire why this was the case, after searching the web I found that to the best of my understanding that the new sprint phones are all coming with one chip to access a cell signal instead of two like my note 3. If I've misspoke about the reason my apologies but I believe thats what I understood. Now I'm wandering if I was to use google voice to make calls could I then access data as well? This leads to another question, my understanding is that Sprint customers can allow google voice to use there current mobile number as there google voice number. If anyone has done this I would like to know if there are concerns to have and can you opt out if you no longer want to use the service? Any suggestions are appreciated.

Wow...this sucks! I just tested mine and i cant use data while making a fcuking call. Wtf sprint

Like I said, I've never used Google voice for phone calls but that may be an option I'm just concerned about giving my phone number to google if I want to get it back.

you can always drop Google Voice from your number

Some are using hangouts. You can call and use WiFi for data if available, or you can do both call & data on WiFi.
For 95% its not an issue and Sprint is going VoIP in the near future and will be able to do both then.
The trade-off is better battery life with one antenna compared to having two.

So you can call out without wifi and use data, even with the Hangouts dialer?

So when I'm on 4g I won't be able to call someone using phone? Wtf, I can do that on my note 2...how the hell is this progress?

This is 100% Unsat!!!
I can't believe this has happened. I too need to know if this can be fixed by using Google Voice. You can keep your own number without giving it to GV, but this is completely a backward proposition.

U can only if you are on wifi or 4g while making call. Verizon and Sprint can not do data while on calls unless u are on 4g at the time or WiFi. Its the limitation of having CDMA devices. Att and tmobile doesnt have that issue

Hangouts essentially uses VoIP. Of course it will work. You're not actually making a cellular call with it.
All Sprint Spark LTE phones are incapable of using voice&data at the same time.

So the note 4 is a spark phone but the note 2 isn't?

New technology.. smh
I have the same problem with my LG G3. Cant surf the net while making calls. Its really a disappointment. Somehow Sprint needs to find a way to be able to have Spark and use data at the same dang time. My friend has the Note 4 as well and told me she could talk and use the net but I think she BS-n.

No Simo Voice/Data
With Sprink Spark, You can no longer have simo talk/text. It's a single signal. Instead of CDMA / GSM on LTE Devices. It is only allowing one. Now that isnt due to the phone. It's the towers and the tech they are using. I heard they are in the works to update that and there will eventually be a fix.
I work for Sprint.

I think you meant "...simo talk/data"...

Are you telling me a bunch of sprint user's didn't know that spark phone's wasn't capable of talking and surfing the web at the same time using the phone data network lmao? Seriously why don't you guy's look up info before purchasing a phone first lmao this has been known since the first spark phone which was what i think the lg g2 if I'm not mistaken but no wait it's sprint fault for taking the direction they choose to better their network and services lol.

a little off

Most sprint phones dont have that capability, but yes the note 2, 3, and gs4 and 3 do . I have had them all and all work when on 4g and of course WIFI. It has nothing to do with the limitations of the CDMA network, its the hardware that they put in them. (as well) yes it is easier to do over GSM and they usually have that feature. though This is something that we should have been let known and also should have been worked out before putting (or lack thereof) something like taking those antennas out in play before getting the network right. Most of us cant use spark anyway! lol so now its no spark and you cant be on the phone and get 4g either, on the newest phones, G3, S5, Note 4 ETC....

When you say eventually... Have they actually given some type of internal horizon or if it eventually like paying off the national debt?

Why is both WiFi and LTE showing in my status bar when im on a WiFi connection? Yes, I do have download booster on, but it was doing this way before I enabled that for the first time.

T-Mobile One - Pixel 2 XL Signal Issues?

Well I'm testing out T-Mobile in my area since AT&T is frankly getting too expensive for me. I received my SIM card today, turned the phone off, put it in, and powered back on. Everything seems to be working and upon initial boot I show LTE.. Then I eventually see 3G, then H+ ... My area is saturated with LTE for T-Mobile and I'm a bit confused as to why I'm having such an issue with signal. Signal with my AT&T wasn't horrible, but never dropped LTE on me while in my home.
Is there anything specific I can do to improve reception at all? I am running DP2 of Android P.. Maybe there's an issue there.. I can't seem to figure this out. T-Mobile says everything should be running fine as the coverage is there.

Just a thought, don't know if it'll help or not. Have you thought about fastbooting a different radio from the latest 8.1 factory image?? I honesty don't know if there's any difference between them, but it maybe worth a shot. If your bootloader unlocked of course

Always unlocked, and I did flash back to the May 8.1 update. It did improve a little.. it's just a puzzling situation. There's a T-Mobile tower less than a mile from me up on a hill a bit. It's very close.. Maybe too close? I don't know.. I get LTE from it.. Luckily a signal booster from them is free and may help. So far I haven't dropped signal completely since going back to 8.1 but it's running close to -119 which I think if memory serves, is very low.

I have been on T-Mobile for years. My signal on my Pixel 2 XL has been really good except my friend's new apartment, but I think it's because the building is blocking the signal really heavily.

10 to 1 your actually too close to the tower and the signal is actually going over the top of you. What happens when you get 2-3 miles away from it. This is all just spec on my part though ?

I never thought of that.. my house is a total dead zone. I drove around town and was getting 100+Mbps download speeds, amazing signal. So it's not the phone/radio. It's either I'm too close, or something odd with the tower. Maybe it's an old 2G tower they 'turned into' LTE? I don't know, I do know it's one of the oldest radio towers in town.. I drove as close to the tower as I could without trespassing.. I know the signal could be going over my head, but it only pulled about 23Mbps ... Closer to downtown I was pulling 120+Mbps on the speed test..
Not sure there's anything I can really do other than ask for a booster for the house and see if that helps. I can do without signal at home due to the Wifi calling, but is that a risk? I have a landline, but only for work.. May have to pull double duty.. All this is to save myself some money.. 4 Paid Lines with T-Mobile is cheaper than 3 Paid lines and one free line with AT&T.. it's crazy..

It may have something to do with the Android Beta's, I remember seeing signal issues like this on the Oreo beta as well.
Are you still seeing signal issues on the may security patch?

There is a tmo specific flash for June.

And the build is working for the most part....

Damn that sucks, Call up tmo tech support and have them investigate that issue. They usually do a test in your area, and if they can't fix the issue they'll make note of it and install another tower.

Havent had any issues so i would say YES!:good:

The latest June release did fix some issues.. but didn't fix the issues in my home. Seems the signal in the area has issues penetrating some buildings. A tower is close but the theory from T-Mobile and others that I've talked to on here and elsewhere is the tower is just a bit too close and likely going over my head. They sent me a CellSpot. This thing is amazing! Connects to my ISP and uses that to 'phone home' to T-Mobile. It sends out full signals of 3G/4G and 4G LTE. It's amazing and free! Sends a strong signal outside of the house and around too.. T-Mobile is something else!!

So when you say ISP, you mean T-Mobiles network?

No, it's actually connected to my ISP Suddenlink. I don't know how it all works, but through the internet, when I'm using LTE instead of regular Wifi, it's using the T-Mobile Network but through my ISP connection. I don't know how it works, but my signal is roughly -60 to -50 at all times inside and outside around my house.
