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?

    • In the conference call they had two question on additional spectrum. One was the 800 spectrum. They are not certain what will happen, thus have not really put it into their plans either way (sale or no sale). They do have a reserve level. Nationwide 800Mhz is seen as great for new technologies which I presume is IOT or 5g slices.  T-Mobile did not bite on use of their c-band or DOD.  mmWave rapidly approaching deadlines not mentioned at all. FWA brushes on this as it deals with underutilized spectrum on a sector by sector basis.  They are willing to take more money to allow FWA to be mobile (think RV or camping). Unsure if this represents a higher priority, for example, FWA Mobile in RVs in Walmart parking lots working where mobile phones need all the capacity. In terms of FWA capacity, their offload strategy is fiber through joint ventures where T-Mobile does the marketing, sales, and customer support while the fiber company does the network planning and installation.  50%-50% financial split not being consolidated into their books. I think discussion of other spectrum would have diluted the fiber joint venture discussion. They do have a fund which one use is to purchase new spectrum. Sale of the 800Mhz would go into this. It should be noted that they continue to buy 2.5Ghz spectrum from schools etc to replace leases. They will have a conference this fall  to update their overall strategies. Other notes from the call are 75% of the phones on the network are 5g. About 85% of their sites have n41, n25, and n71, 90% 5g.  93% of traffic is on midband.  SA is also adding to their performance advantage, which they figure is still ahead of other carriers by two years. It took two weeks to put the auction 108 spectrum to use at their existing sites. Mention was also made that their site spacing was designed for midrange thus no gaps in n41 coverage, while competitors was designed for lowband thus toggles back and forth for n77 also with its shorter range.  
    • The manual network selection sounds like it isn't always scanning NR, hence Dish not showing up. Your easiest way to force Dish is going to be forcing the phone into NR-only mode (*#*#4636#*#* menu?), since rainbow sims don't support SA on T-Mobile.
    • "The company’s unique multi-layer approach to 5G, with dedicated standalone 5G deployed nationwide across 600MHz, 1.9GHz, and 2.5GHz delivers customers a consistently strong experience, with 85% of 5G traffic on sites with all three spectrum bands deployed." Meanwhile they are very close to a construction deadline June 1 for 850Mhz of mmWave in most of Ohio covering 27500-28350Mhz expiring 6/8/2028. No reported sightings.  Buildout notice issue sent by FCC in March 5, 2024 https://wireless2.fcc.gov/UlsApp/letterPdf/LetterPdfController?licId=4019733&letterVersionId=178&autoLetterId=13060705&letterCode=CR&radioServiceCode=UU&op=LetterPdf&licSide=Y&archive=null&letterTo=L  No soecific permits seen in a quick check of Columbus. They also have an additional 200Mhz covering at 24350-25450 Mhz and 24950-25050Mhz with no buildout date expiring 12/11/2029.

They're completely avoiding talking about mmWave.
