Signal issues with the galaxy nexus

Recommended Posts

Well, as i have gotten a galaxy nexus at long last, ive noticed that other sprint phones have been constantly getting better signal than my phone has. For example, when i went to the sprint store, my phone varies from 1-2 bars in the store. When i would go over to any other sprint phones, they would have at least 3-5 bars. And this was more than just one different sprint phone that did it, it was every phone in the store that had a better signal than mine, except for the galaxy nexus at the store. It had the same signal strength as mine did.. Radio issue possibly??

Did you look at the actual signal numbers? Or just the bars? There is nothing scientific about the bars.

Yes, i have looked at the dBm values. At times, the difference between my value and other sprint phones values ranged from a 4 to 10 dBm difference. When one sprint phone would have a -93dBm signal strength, mine would be around -105 to -109dBm signal strength.. I can not figure out why this happens Edited by rwhittaker13

It is possible that the nexus has a slightly weaker radio... I have noticed slightly improved signal strength numbers and bars since going from the gnex to the gs3, but I have not noticed additional coverage area due to the "better" signal strength. There are a couple places that I occasionally visit that I would drop calls and/or have no signal with the gnex, and the GS3 behaves the same in those areas.

Part of the problem seems to be that the Galaxy Nexus uses an off brand VIA Telecom baseband for its CDMA2000 chipset. Honestly, this late in the game, I do not know why you would want to pick up a Galaxy Nexus.

Because of my broken LG Viper, sprint said they would replace my phone with a different model and the galaxy nexus was the other model i could choose to replace the viper with, so i did. Not a bad phone really, it still lives up to its name.

The Galaxy Nexus has the weakest 1x/EVDO radio performance of all Sprint LTE devices I've tested. On par with one of the weakest devices of all time...the Samsung Epic 4G.

Full agreement there..

finally got something helpful....

 

Sometimes it helps to be a HAM radio licensee..:) I worked my way up to a level 3 escalation on the airave where i had sprint and airvana directly involved. It turns out there is a known issue with the airvana 2.5 and andriod LTE devices. the phones try to query the airvana for LTE which fails...the phone then de-registers from the airave and then recycles on 3g and connects. Things are fine until the phone tries to find 4G at the airave again..rinse repeat. This only affects the 2.5 AFAIK. The solution is to disable 4g and lock the phone into 3g when on the airave. I've also noticed the signal the 2.5 is throwing out is very hot. I live in a 2200 sqft house but i had to have them turn it down to 1500sqft to keep the rest of the phones from getting blasted off the air as well.(google receiver rf detuning). Airvana now has an active ticket on this inssue internally on their end as well...here's to hoping this will get fixed now. I've now got the reduced power and the 4G disabled on my GNEX. I'll report back with the results.

well the issue has accelerated. my gnex now drops the airvana completely on a regular basis. it appears either sprint or the device itself keeps jacking the rf output up to high and that's blasting phones off the airvana again. What a piece of junk.

according to sprint on the airave when the system polls for 4g the airave can and does often drop the device that did the 4g poll while connected to the airave. it having a via chipset explains quite a bit on my signal issues.

 

I don't believe that at all unless maybe it picks up a fringe LTE signal that is unusable.

 

Just not the way it works. Kinda like saying your phone will drop the 1x connection to scan for EVDO.

that's what i been told by more than one level 3 airave technician. My symptoms and further research bear that out. Various sprint forums have multiple threads on multiple Android phones and the 2.5. i even have an offer from Sprint airave tech support that if i can find a 2.0 on ebay up to a certain amount all i have to do is grab it, send them proof of purchase and they'll credit my account for the purchase. i just called back this morning and that offer is legit...so it's a major issue that's just being kept under wraps right now. Here's to hoping sprint gets this fixed right quick. You can't get more definitive than that.

I will rephrase..when the phone polls for 4g while connected to the airave the airave can and usually does drop the device doing the polling especially if the device is andriod based...it's due to a bug in the firmware of the airave.

This thread explains my signal frustration. Anyone else's Gnex get exceptionally hot on the top half of the phone? Pretty much any activity is causing my phone to get really hot.

Yep. All the time. I'm taking mine in tomorrow, and as soon as I get the replacement, I'm selling it on ebay to subsidize the cost of my new iPhone 5. Good thing I kept my EVO Shift around for something, lol.

      Even though Sprint doesn't have the best coverage in my area. I do have lots of memories and nostalgia with the company. I wonder who else here will miss Sprint besides me?

      Its almost time for the next iteration of Samsung's Galaxy Phones! I'm planning on pre-ordering either the S20+ or Ultra. Current Rumors have it going on Pre-order February 11.  Let the discussion commence...

      I'm new to this forum, and I've seen people mention cell sites with specific ID's (for example, SF33XC664). Is there any significance to these ID's, and is there a way to decode them? Also, how do I figure out what the cell site ID's are for towers near me?
      Thanks! I'm excited to start talking on this site more 😀

      Samsung Network Vision equipment are highly distinct and fairly easy to spot compared to the equipment that other vendors are deploying. Sprint is Samsung's first extremely massive American contract (baring Clearwire) so there  should be no issues in confusing these equipment for another carrier which happens often with Ericsson NV equipment.

      Below are images of Samsung equipment which includes antennas, remote radio units, base stations, and their mounting configurations.

    • Just figured out this is a waste of time. US Mobile and Verizon lock the eSim to the emei while T-Mobile only uses it to see that you have a capable phone, like Red Pocket does with physical sims (although RP does keep track of what phone you are using it on with the emei.)  So @Trip was right in this case on liking physical sims.
    • Verizon has a reputation for being frugal with MVNOs. After looking around, I also decided US Mobile was my best option. People have gotten C band on it.  Hoping for esim for my S21 Ultra.  No luck so far.  Red Pocket does not claim Verizon 5g, although they say Soon!(TM).  I do see some 5g with it. Typically MVNOs are deprioritized, thus I am reluctant to claim truly getting top speeds with one.
    • Did some exploring yesterday/last night and didn't find a shred of C-Band, including with my brand new US Mobile SIM. Did find 4CA CBRS but the site seemed backhaul constrained; both that plus 15x15 B2 and band-locked 2/66 got me 190 Mbps or so.
    • Did some more exploring yesterday/last night and I think I spotted some LAA downtown but didn't get a chance to confirm before it went away in favor of mmW, which also went away pretty quickly. Also saw another n66 site, as well as an n2 site, making AT&T the second carrier to run n2 DSS within a few miles of me. I think at this point they won't be able to advertise anything flashy, but due to the sheer amount of CA they're throwing at customers here they can keep their network at 50+ Mbps until they can deploy both 3.45 and 3.7, and that's probably enough.
