[Q] Radio quirkiness amongst different nexii (Verizon)

My nexus is a hw version 9. it had some hand off issues from wifi to data with the 4.0.2 radios. the 4.0.3 and 4.0.4 work so well i almost thought they could do no wrong. until i got my wife's nexus which is hw version 10. this one works fine with 4.0.2 doing handoffs just fine, but with 4.0.3 and 4.0.4 i get this weird signal drop every once in a while where the network goes away, the bars become a solid dark grey triangle for 2-3 seconds, then connectivity comes back and data shortly thereafter. anyone else seen this?
UPDATE:
i noticed the problem happened even with the 4.0.2 radio. also the longer the phone went without a boot cycle the more frequent the problem became. asked for a replacement and got a CLNR which is hw9 that doesnt seem to have a problem.
see post here
http://forum.xda-developers.com/showpost.php?p=23621403&postcount=15

where are you determining what hw version you have?

the bootloader for one. also the about phone says it in the radios/baseband.
the version 9 reads 1515.09
and the 10 reads 1515.10

Got it. I have version 9 as well. I live outside of a 4G area so I pop in and out of 4G coverage quite often. Personally the 404 radios are working the best for me right now, switching between 3G/4G is pretty seamless. Though I cant honestly say I have had the device in my hand, screen on, and using DATA while it went from one service to another.

yeah thats how my hw9 behaves.
im parked solidly in the middle of a 4g zone and the hw10 just loses all connectivity albeit for just a couple of seconds on the 4.0.4.
4.0.2 works fine.

I'm on HW 10 and the 4.0.2 radios work great.No issues here and no problems with dropped data.

I am HW 10, 4.02 Stock.
And my GNex has been dropping data+voice every 5 mins when I try to use 4G. As long as LTE is off, 3G+voice is fine.
I also have tried 4.04, and same problem...and came back to stock 4.02 and waiting for OTA I guess..or that's what VZW tells me to do...

I had just mentioned this in another thread, but I haven't had the loss of call audio bug since my rev 10 device.
At the same time, my wife has a rev 09 device, and never had it. We are both on 404 radios, and I only drop data when in fringe areas. I never, ever, drop voice.
charlescom, dropping LTE does not affect voice.

Consider yourself very lucky. I'm about to get rid of this phone because of it.

Adrynalyne, that is what I thought until I bought gnex.
Check out this google issue if you are so lucky to have picked a good gnex out of lemons.
This is one of major flaws that affected so many gnex users. Officially titled gray triangle of death....

If you scroll all the way down, you will see all the screen shots I uploaded on exactly what a user faces as the voice and lte drops...
Thank you..

Yeah, I have never seen that before.
Weird.
Edit: Allow me to rephrase. I did have that once. It was a bad sim.

I have this issue. Stock 4.0.2. Have only had the phone for like a week and it is pissing me off

That does look potentially SIM related. The VZ phones do have a micro sized SIM card.
With posters reporting the same issue on multiple replacement phones, I wonder... was the same SIM card transferred to the next new phone?

At least at my location SIM replacement was the first thing on the list way before vzw even start thinking about giving out a replacement. And yes, I have been given so many SIM replacements you dont even know....and as far as bad batch goes.....why are there so many bad batches to begin with.....hahahahahaha...it is almost a joke. I am not even getting frustrated any more...i just laugh....lol

it was definitely not sim related. its my wifes gnex and i swapped sims with her. her phone gave me the same problem with my sim and her sim worked fine in my phone.
doing some more research, here is the findings.
my phone - hw9 - works flawlessly
her phone - hw10 - has problem
got a CLNR from verizon which is hw9 which seems to work flawlessly again.
interesting thing is the difference between the stickers on the insides of the bad and replacement phone:

the good one (CLNR hw9) is the left and the bad one (new hw10) is the right.
there is a long thread on rootz about this very issue and the conclusion is that if u have this particular problem, its hardware, go get a replacement.

I'm trying to activate my nexus but sprint can't seem to...

hi, i just bought my nexus brand new on ebay, i turned to play with it this mourning and then took it to sprint to get it activated. the lady told me that the phone cant be activated, that it doesn't show as stolen or anything but that it cant be activated

Doesn't sound like a definitive answer. I would talk to someone else. There is always a reason why.

Did u buy a GSM or CDMA phone. U need to make sure it was the sprint version not the Verizon or the GSM version.

A sprint store should be able to figure it out. If it's a brand new phone I don't see why not.

What plan do you have?

Can't activate on Verizon either
I'm having the same problem-- but with Verizon. Bought it from ebay, in great communication with the seller who is trying to help.
Phone isn't stolen/lost; no outstanding balances on the phone or my plan.
Factory data reset didn't help one bit. Can't activate fully-- just get internet (no calls/texts).

Did you get a new 4g sim card with your new phone? Or a sim replacement? You need to activate the sim card, but as long as its already activated, any device should work.

If they can't activate it has to be GSM or verizon

Are you sure it's a Sprint Galaxy Nexus? Take some pictures of the phone. What does the backcover contain?

Yep, this is the third new SIM (LTE) card. Been to both the store and on the phone with Verizon tech reps.
Tech reps say activation is "stuck at the switch" (this is day 3... btw)
should I unroot it? I've already done 2 factory data resets.... Or should I just wait it out?

Are you on a ROM?
I know someone who couldn't get it to activate the Sim while on a custom ROM (liquid i believe)
They ended up putting the Sim in display nexus, activated, put Sim back in his and it worked lol

A lot of custom roms do not have all the required proprietaries needed for such things like sim activation. Or they include them, but do not sign them correctly.

I don't suggest asking them to put it in a display device to activate....i don't think they normally do that and will probably look at you like you have spiders crawling out your nose lol
Just put it on a stock ROM
When i got my nexus it came with liquid on it unlockedrooted
i just flashed the 4.04 stock ROM build that bird man compiled found over at rootzwiki and it got activated
At this point you have the option of putting the official stock 4.04 vzw build on it tho which i would recommend, preferably one without any tweaks, rooted should be fine tho
To the OP, try putting your self on a stock ROM for sprint and you should be gravy
Good luck!
Let us know if it works guys!

Moving from freedompop to sprint

I kind of have a troublesome story. I bought a phone on ebay and activated with freedom pop an MVNO of sprint. I cancel the service after the gigabyte was used. I then tried to activate with sprint and was unable to do so. They said the ESN was in use and could not be activated. I called freedom pop and completely deleted me from the databases and removed my account. I am still having trouble activating the phone. Do you guys have any idea what could be causing this?

What is the actual message or error it gives you when trying to activate? Have you tried dialing ##72786# to do a carrier reset?

My ROM: WICKED X

I'm having the same problem. I Bought a used Sprint S3 and activated it on freedompop. I deactivated the freedompop account. When I check the ESN / IMEI on swappa.com it shows :
Activation Status Clear (Sprint / MVNO)
Device appears to be activation ready.
However Sprint will not activate it. Their system gives an error. I don't know what the specific error is. I put the ESN into Ting.com and it said that it would activate. Interestingly, I bought another used Sprint S3 and did not active it on freedompop. It did activate on Sprint without any problems.
This is the second phone that I've tried this with. The first is a Samsung Victory 4G LTE that I had purchased from freedompop a few months ago. I found the stock Sprint ROM and reflashed it. Took it into the Sprint store and they couldn't activate it. I've reset the phone and done the carrier reset. No joy.
It's starting to look like once a phone gets registered with freedompop, it can't go back to Sprint. Which is sad, because I think a lot of people who try freedompop are going to want to find another service because freedompop is just not reliable.

I tried the same thing. Checked ESN on swappa and ting ESN was clear and ready to activate. I have heard multiple answers.
1. You need a cool down period after freedom pop
2. You can not activate on sprint after flashing to an MVNO
Sprint would also not add the ESN back into there system. I guess it is time to sell phone on ebay as a freedom pop phone. Can phone still be activated on ting or just freedom pop?

I read a thread on Sprint's forums about someone who tried this and succeeded. I pm'd him and he said that he had to open a service ticket with support. Eventually, he found the right person who knew how to add the MEID to the database. It seems when you activate with an MVNO, the MEID gets moved to a different database. And only a few people know how to move it back.
I did check the MEID with ting and it said it would activate.

Personally if you use WIFI a lot and dont use a lot of mobile data i would suggest ting.
They also have tools on their web site to help figure out how much you can expect to pay moving to them. I have had ting for about 6 months now ( after walmart family mobile) and I save money and have better coverage. I have had great experiences with customer service.
If you are inteterested in joining ting send me a PM and i can shoot you a referral and we can both save some money.

Do you know how to create a support ticket on sprints website? I use a lot of data. I don't think ting would work.

Freedompop = bad
I'm still trying to get this phone back to Sprint, but I'm getting worn down. Their tech support is non existent. If the problem can't be corrected by a factory reset, they're lost. Not one of the people that I've talked to so far even knows what freedompop is. I can completely understand why sprint is losing two million dollars a day and their stock is in free fall.
It's so easy for freedompop to move a phone from sprint to MVNO, but it's looking next to impossible to move it back.

I called sprint customer care. They told me to call a sprint repair store to fix my problem. I called a corporate repair store and said it could not be moved back to sprint. I don't see why it is so difficult. Seems like any easy database move.

As I understand it from reading posts on Sprint's forums, the hard part is finding one of the few people at sprint who know how to add the MEID to the database. The people at the stores are not useful beyond doing a factory reset or replacing a battery.

AT&T compatibility

For those of you using AT&T. Do not update your IMEI at this time and hope that the system doesn't auto update it. LTE is not supported on the OP3. I am currently stuck on 4G due to this problem.
I have opened a ticket to get the OP3 registered. I will date back here.

My ATT service is perfect with LTE.
Update your APN's

Nextgenphone and ATT Phone. The network is blocking LTE access. Your IMEI hasn't updated yet. Mine worked fine for a few hours.
I work in a cor AT&T store. There were features removed when I changed my IMEI. Once AT&T updates their IMEI database it'll be fine.

I've had the phone since noon on Friday and still no issues with AT&T. I have not called to change IMEI.

I am having same problem, my two devices are stuck in HSPA mode. I spent over an hour online chat with AT&T to no resolution. They tried but could not understand the problem. I had the phones activated at corporate store today too. Hopefully this problem gets resolved soon.

Guys don't bother with the att reps. Most of them have no idea what they are doing with an iPhone let alone anything else. The worst thing you can do is call them for help.

I agree with zelendel even though I work for the company. I am sure I'm not the only person who has opened a ticket to the OP3 added. In the mean time if you call customer service and just ask them to have a manager approve adding the nextgenphone apn to your line then it will fix the issue temporarily. I have LTE back for the time being.

How temporarily is the fix? And is there an eta on when att will fix the problem? I will be returning this phone if I can't use LTE on it.

So will this phone be updated and approved to receive LTE in the future by att? This is kind of a major deal if not.

Too late for it to be approved. This is one of the things you learn to deal with when you buy China based devices. They don't get approved by the Fcc which in turn causes issues with LTE and what not.

So because of you I should expect to see a text from AT&T saying they've detected that I'm using a smartphone and have added an expensive data plan? Great.
Pretty sure you just needed to use the right APN.

Pretty sure I know the right APN. What plan are you on that's worth saving...senior talk 200? That's the only plan in the last 10 years that's cheaper than any new plan which all include data. Please don't be a **** because you didn't have a problem. Others will and when they do its nice to help them understand what's wrong.

im on at&t go and it worked out of the box with LTE.

if what the OP said is true, u can get another IMEI that uses a nano sim card and then call att to activate that IMEI with att and then just reinsert the sim into the OP3 without calling, I did not update IMEI either but i do have a little issues with downloading things it switches back and forth quickly between 4+ and LTE but still get good speeds

Just opened my OP3 an hour ago and put my ATT nano sim in.

Yeah my LTE worked fine for at least 5 hours after I changed the IMEI. I was at work on WiFi so I don't know when it quit exactly. Even putting my sim back in a recognized device yielded no data. Called in got the nextgenphone added to my line, LTE came back. The problem with using another IMEI is sooner or later the system will update and you end up with no data.

Changing the IMEI is not only illegal but can also cause other issues with the device it's self.

The IMEI will be updated when they scan the network which they do from time to time.

Straight Talk AT&T Nightmare

I have used straight talk since I had my Oneplus One and always used AT&T towers. I've always received 4G LTE with that device. Since recently purchasing the Oneplus 3 and activating my new AT&T sim from straight talk, I have only gotten 3G with straight talks recommended APN settings. After spending hours on the phone with straight talk reassuring my phone has LTE capabilities.
I did do research about this problem and it looks like AT&T does not recognize this IMEI as an LTE compatible phone. After attempting to tell straight talk to try and activate my IMEI as an LTE compatible device, they sent me to AT&T. Which after being bounced around multiple times, even to some number that just gave me ads. They finally just told me they can not do anything because I have a straight talk account.
I then threw this sim card into multiple devices and received 4G on all of them.
So long story short, if anyone has had any experience or advice with this problem please comment otherwise I'm just going to change service providers... F*** Straight Talk.

I used to get a Straight Talk SIM for summer motorcycle trips. I have T-Mobile and after ATT tried to buy them, my phone didn't have service in lots of places that it did before.
Now I notice that ATT has the same $45/month pre-paid plan that I used to get on Straight Talk. You might try that one and see if it works for you.

I have straight talk AT&T with no problems. I had to try a few APN to get one that worked. I just Google Straight Talk AT&T APN settings. They are a lot to try. Try one and wait 5 to 10. It takes time for the new APN to kick in. Once it goes LTE, it will go straight to it now. It is not straight talk issue it is AT&T issue. They give MVNO providers low priority. That is why it takes time to get it to go LTE. I will take screen shot of my settings to see if they work for you.

Thanks, but no go. After testing settings, I flashed Freedom OS and it shows HSPA+. with both the settings you provided and the ones straight talk specifically provided me.
I did do a speed test and got 194ms ping, 5.26mb download and 1.34mb upload if anyone can compare.

Tried these settings already, after allowing hours for it to turn to 4G and multiple reboots. I'm still left with HSPA+. I'm quickly thinking this could be a modem hardware issue. I've tried installing most of the custom Roms available and as soon as I connect to a wifi network it restarts the phone and will keep restarting as soon as it connects to a wifi network . The only Roms that work are oxygen and freedom os. ��

There shouldn't be any difference between straight talk and legacy AT&T. Did you try running the phone using AT&T APN settings Instead if straight talk?
For what's it's worth, I have AT&T and I've had trouble with the hand-off from 3G to LTE. I live in an area without LTE but can drive in any direction half a mile and get LTE. The same thing was true with my LG3, but the hand-off was seamless.
T-mobile has enhanced LTE in my area and I'm now testing straight talk T-mobile in my second SIM slot.
It automatically loaded the T-mobile APNs and they work, as does straight talk.
I'm getting 2 bars of T-mobile LTE now and so there is no hand-off issue.
If all goes well for a month, I'll dump AT&T and either stay with straight talk or move to T-mobile.

Ditto
I share the same problem, OnePlus 3t on straight talk using at&t sim card. I can only get H+ on the status bar. Speed test max speeds of 10Mbps, usually around 6-7Mbps. I have scoured the internet for a solution to no avail. Tried swapping the sim card from my son's Galaxy S4 on the same network, but still H+ only. Both sim cards pull 30-50Mbps lte speeds in the S4. Both sim cards pull 4-6Mbps in the 3t. S4 is rooted running synergy mod flawlessly. I tried every apn on the internet. Even flashed back to stock rooted from lineage Pie. Entered the phone information page from the dialer menu. Lte physical configuration is blank?
Called straight talk, but their system hangs up on you when you get transfered to the department with some expertise, if that really exists there? None of my efforts got me lte. I really like this phone, this issue makes me feel like ditching the high-end garbage for something old but reliable. Makes no sense why so many 3t users get 4g lte with no problem, but then a few of us don't? See the screenshot of phone information.
