Samsung Galaxy S3 issues (toggling airplane to get LTE)

Hey guys, I am trying to see if anyone is having a same issue as me. LTE just came to my area and I will be standing in a spot that has LTE doing speed tests. It will toggle me back to 3G, and then I will have to toggle airplane mode to get back to LTE. Has anyone has a similar problem, and if so, what did you do to fix it? Also, another thing I noticed while doing speedtests, my phone showed that I was on 3G, but when I looked at the results of the speed test, it showed me as being on LTE.. I am rooted running the FreeGS3 ROM. I am not sure if this may be the issue or not. I know that EVO LTE's seemed to have this issue in the past, but I have NEVER seen or heard of someone having the issue with the S3 (and yes, I did google around)

Also since you are on that wonderful FreeGS3 ROM (being sarcastic), we had a member in the NOLA market do an entire day of 4G mapping only to have absolutely ZERO of his points show up on Sensorly. It seems the Dev of this ROM thought it would be cute to change the network name so Sensorly throws all the points to the curb instead of putting them on the map.

 

So before you map anything with Sensorly please make sure it goes up on the map before spending time mapping your area out.

Yeah, I notice this. I mapped my neighbor hood out and it didnt show =/ but mapped SCC and it showed. So not sure if someone else mapped it. I love this ROM but may have to switch to another one =/

I'm having this issue on my S3 also. Airplane mode seems to solve it sometimes, but more often than not, I have to restart the phone. I'll be standing underneath a LTE tower and be reading 3G. The "LTE Enginerring" (sic) debug screen will show -119db, or wherever the last signal was when it faded out (coverage is spotty in Detroit at this time). I can't figure it out for the life of me.

I know the latest update for the Note2 changed the scan to 5 minutes, probably the same the S3. But I know that interval is not entirely true as I've seen the phone pick up LTE in the almost the same place several times.

 

In the debug screen, what shows for the MCC MNC when it is "stuck"? 000's?

    • Their offers have been crap recently, so this is just more evidence to not buy from T-Mobile. 
    • T-Mobile Will Soon Prevent Early Payoff Of Phones Receiving Bill Credits If you finance a phone with T-Mobile it will remain locked until paid off but now you won't be able to pay off early. If you don't currently purchase your phones from the manufacturer here is another reason it might be a good idea.
    • Was in Red Hook again and I swear there are more Link5G sites as there are Verizon, T-Mobile, and AT&T small cells combined in the entire neighborhood. It seemed like every other street I turned down had one installed. Hopefully carriers will start hopping on them soon. Seems like a lot of effort to go through for no one to use them.  — — — — — T-Mobile converted the Sprint site on top of NYU Langone Brooklyn in Sunset Park. I first mapped one sector of it back in November 2023 but I thought it was a small cell so I never pinned it but I ran into another sector today which caught me off guard. I'm unable to find a permit for the conversion so it's definitely a surprise. There's another T-Mobile site 1 block away that T-Mobile initially installed back in 2019 so I'm kinda surprised they're keeping both considering the Sprint conversion is on a much taller building and could potentially provide much better coverage to the entire area.  — — — — —  Old permit for this new install expired but a new one was recently issued. It's gonna be similar to the site at 360 Forman St in Brooklyn Heights. Permit calls for only 3 antennas to be installed so I'm assuming it gonna be Band 2/41/66 and n25/41 only which is a bit of a downgrade from the now decommissioned full build that was on 871 7th Ave but in it's current state the nearest macro is a few blocks away and a small cell at Broadway and 55th is doing a lot of heavy lifting in the area so anything helps.  
    • Still not seeing any ULS postings for pending T-Mobile UScellular merger in Dane county Wisconsin.
    • Came across another Crown Castle Solutions multi-tenant oDAS node in Brooklyn. Located at 40.7002286, -73.9612666. Nothing on T-Mobile or AT&T so I'm assuming these are all Verizon nodes that Crown Castle is anticipating another carrier will hop on down the line.
