LTE drops signal prematurely, solution?


Recommended Posts

When my Galaxy Nexus is in Evdo/LTE mode, my 4g signal cuts in and out, jumping from 3g to 4g every minute or so. My LTE signal is ranging from -89dbm to -120dbm.

 

If I force my galaxy nexus to do LTE only, I can get a consistent 6mbps up/down even at -120dbm. Is there anyway to change this dropoff point so it will always hang onto the LTE signal in Evdo/LTE mode? I know you could do this on wimax phones, (http://forum.xda-dev...d.php?t=1566704) but when I enter *#*#3282#*#* on my galaxy nexus, I don't see an option to change signal dropout points anywhere. I'm also running CM9 if that makes any difference.

 

Is there anyone else having this issue, and does anyone know of a solution?

At the moment there is no way to tell if its your phone or the network so just wait a few days and see if it gets better or stays the same. For what its worth, I will say that I haven't had any connectivity issues with my gnex or my evo lte so far.

Good find with the forcing on of LTE and finding that you can still pull that much down. If it is possibly to change the hand off dbm I'm sure someone will find a way to do it soon. However, since you are running CM9 that may explain why you don't already have that option. I know when I ran custom roms on my Samsung Epic I didn't have all of the debug options that I had on the stock rom.

I'll try going back to stock and see if there are anymore options. Thanks!

Sorry, I forgot to mention that this is only happening in my basement. I have no reception problems elsewhere.

I know on the evo lte when you do ##data# and go to edit mode then select Evdo you have an option to change to LTE mode only (I did this but since so lte here yet it to no signal lol)

dial ##3282# edit enter your msl code and click edvo change from ehrp/lte to just cdma/lte and it locks it does change back randomly sometimes after a call.or text message just change it back. getting speeds of 4-5 down with -109db signal loss

    • Since this is kind of the general chat thread, I have to share this humorous story (at least it is to me): Since around February/March of this year, my S22U has been an absolute pain to charge. USB-C cables would immediately fall out and it progressively got worse and worse until it often took me a number of minutes to get the angle of the cable juuuussst right to get charging to occur at all (not exaggerating). The connection was so weak that even walking heavily could cause the cable to disconnect. I tried cleaning out the port with a stable, a paperclip, etc. Some dust/lint/dirt came out but the connection didn't improve one bit. Needless to say, this was a MONSTER headache and had me hating this phone. I just didn't have the finances right now for a replacement.  Which brings us to the night before last. I am angry as hell because I had spent five minutes trying to get this phone to charge and failed. I am looking in the port and I notice it doesn't look right. The walls look rough and, using a staple, the back and walls feel REALLY rough and very hard. I get some lint/dust out with the staple and it improves charging in the sense I can get it to charge but it doesn't remove any of the hard stuff. It's late and it's charging, so that's enough for now. I decide it's time to see if that hard stuff is part of the connector or not. More aggressive methods are needed! I work in a biochem lab and we have a lot of different sizes of disposable needles available. So, yesterday morning, while in the lab I grab a few different sizes of needles between 26AWG and 31 AWG. When I got home, I got to work and start probing the connector with the 26 AWG and 31 AWG needle. The stuff feels extremely hard, almost like it was part of the connector, but a bit does break off. Under examination of the bit, it's almost sandy with dust/lint embedded in it. It's not part of the connector but instead some sort of rock-hard crap! That's when I remember that I had done some rock hounding at the end of last year and in January. This involved lots of digging in very sandy/dusty soils; soils which bare more than a passing resemblance to the crap in the connector. We have our answer, this debris is basically compacted/cemented rock dust. Over time, moisture in the area combined with the compression from inserting the USB-C connector had turned it into cement. I start going nuts chiseling away at it with the 26 AWG needle. After about 5-10 minutes of constant chiseling and scraping with the 26AWG and 31AWG needles, I see the first signs of metal at the back of the connector. So it is metal around the outsides! Another 5 minutes of work and I have scraped away pretty much all of the crap in the connector. A few finishing passes with the 31AWG needle, a blast of compressed air, and it is time to see if this helped any. I plug my regular USB-C cable and holy crap it clicks into place; it hasn't done that since February! I pick up the phone and the cable has actually latched! The connector works pretty much like it did over a year ago, it's almost like having a brand new phone!
    • That's odd, they are usually almost lock step with TMO. I forgot to mention this also includes the September Security Update.
    • 417.55 MB September security update just downloaded here for S24+ unlocked   Edit:  after Sept security update install, checked and found a 13MB GP System update as well.  Still showing August 1st there however.
