Where is the Guide that Improves 4G by Tweaking Minium Connection Level

Hey All,
I saw a guide on here that was used to change the minimum connection settings for the 4G. It was supposed to give you a better signal.
I searched and couldn't find it anywhere, can someone point to it.
Also have any of you used this and did it help? FYI I am on the absolute 4G border and can get 1 bar in half my house and none in the other half. I am hoping to help it out a little.
Thanks all,
Force

It's in the general section

http://forum.xda-developers.com/showthread.php?t=925898&highlight=fix
It did help just a little. It basically gave me 4G in some spots where I wasn't getting it before. No real speed increase though, for me anyways.

You guys are awesome, thanks, I am just looking to get it in the other half of the house, so this should be perfect. Thanks again

1x/3g

Not sure when and with what ROM this started happening but my signal drops to 1x really frequently. 3G is always going in and out. Any ideas or fixes? Has this been discussed somewhere before? On train ride in to work so haven't searched threads yet! I flashed synergy a few days ago coming from mikg and before that gingerale..and before that cyanogen! It seems like I've had the problem since moving back to sense from cyanogen about a month/month and a half ago.

Where are you located? Have you had speed related issues?
Sprint has been having issues related to the overloading of towers with the excessive growth of data usage [with the boom of the Evo]
Towers are set to send some phones to 1x when 3g usage is high in order to alleviate speed issues for all.
That could explain your issues.

I live in the northwest suburbs outside of downtown Chicago. I work and commute to the city and I experience it the whole ride to and from home. I will be sitting at my desk and randomly go from full 3G to 1x. At home in the suburbs, my signal is terrible in my house already but I do get dropped to 1x as well. Don't really notice any speed changes besides the normal slowdowns from what I am assuming is the congestion.
That sounds like a horrible way to fix their congestion issues! Is this something they just started doing? Like I said in the first post, everything functioned perfect up until a month or two ago. Also, would they apply that to an area as big as Chicago out the suburbs?

It's not a fix, it's just a way to alleviate some congestion while they work on redoing the towers.
I'm not saying this is what's happening to you but it's likely.
You can try to have the phone reactivate itself. [If I recall correctly that function is in ##yourmsl#]
You can get your MSL here.
You can also try to update your PRL and then Data profile.

Same thing here. I've complained to Sprint several times so now they want me to bring my phone in to be checked so I need to unroot. Ugh

Thanks for the info. I will give it a shot. I did update my PRL and profile in that order but didn't seem to help. If nothing helps maybe I'll have to get this bad boy replaced or something.

Also, and before you ask there is no logical reasoning for this and even the very knowledgeable technician that recommended it hasn't figured out why it would do anything, you can try going to ##3282# and clicking "view" and then clicking on EVDO and then backing out and trying the internet.
They don't know why that would do anything and no it doesn't make any sense...but that's exactly why I refuse to go into anything related to working on computers...for being logical they aren't logical...at all.
By the way, doesn't hurt to keep your radios updated.
Best of luck.

Haha, I am actually in IT so I know exactly what you mean. I will try that out as well. And my radios were updated and I was actually considering rolling back to see if that caused any issues for me.

Let me correct myself, sorry I never run Sense, it's ##786# then you hit menu and hit reset.
You need to have your MSL. Also, please note that this will erase your /data and you will lose all personal information.
Furthermore, be sure to cancel when it tries to do a check for firmware update.
This honestly may be more trouble than it worth though.

Thanks, yeah I found the reset option in another thread. I reset, hit the prl update, cancelled the firmware check and will run this around town for the day see if I get 1x. I'll post back here later today. thanks again for the help!

Well used for most of the day and so far so good. Saw it go down 1x once on train compared to everytime I unlocked the phone. Let's hope this isn't temporary . Ill post again after the weekend to test around the suburbs and state to state during a trip to toronto. Thanks again!
Oh and speed still sucks but that's a sprint issue obviously.

I had the same problem a month ago. It's the phone. I tried many different combination of radios and roms but no help. Ended up exchanging it. When you bring in the phone just use the android browser to load a heavy graphic webpage which should take forever in 1x mode.

someone please help, my mind is cannibolizing itselfit

i've exchanged my first galaxy nexus today because i noticed that on really low brightness there were two streaks going down the screen. they were only visible when the brightness was low. i did have it on auto, which means that in dark places, this was the case a lot. anyway, i went to the store where i got the phone and they were really nice and exchanged it for me. big props to popular electronics. now, the screen seems fine. you could still see some streaking on super low brightness, but its definately much better. i would say to most people, even, not noticeable. i'm just anal, i guess. however, it now seems that the phone is a little slower/laggy. i mean some transitions between screens/menus is not as smooth as i think it was on the other phone. now, logically, the same phone running the same software, there's no way it could be different. however, it just seems like it. i don't know if it's just me at this point trying to find something or it's actually slower. i did factory reset twice, before entering all my info. someone, please tell me that's its just me or is actually possible for it to be laggy or for the software to work differently on this phone? almost everything else seems perfectly fine which is why i keep thinking it's just me. sometimes when you get something in your head, you start finding things your looking for.
by the way, i love this phone. have had all the nexus phones since nexus one and this one is by far the best.

Restore it. And chill out and smoke some pot.

i've also just did a speedtest.net test on this new phone and the speeds seem lower. last time i did speedtest on my other nexus, i saw about 10mbps, now the best i got was 7 mbps, most times around 5. could the same radio get a weaker signal this new one.

Unless you averaged dozens and dozens of speedtests then compared both devices in the same place at the same time of day you can't even come close to making a comparison like that.
For the record, I think you're just freaking out...

Yeah, its probably your brain getting the better of you. If you want, you could root your phone and try a custom rom if you wanted more speed? Maybe there was something you turned on in the settings unknowingly, or was already turned on (I have heard about something you can turn on in the settings called 2d gpu rendering or something which makes the performance better but causes compatibility issues with other apps) and don't smoke pot like the first guy suggested.

i think i'm just freaking out too. i just watched a bunch of youtube reviews and it seems those phones worked the same.

alright guys. thanks for the replies. i'm going to leave it alone. the phone is awesome. i was pretty sure i was just being retarded about this whole thing.

[Q] G-apps, 4G, and GPS questions

Hi all. I think this is the right place for this..
I have looked around the forum and I have gotten the answers and solutions to some of my questions. But not definite ones.. :L
First, this isn't really ROM related but, is Sprint's 4G still Wimax? And are they ever going to go to LTE?
Second, when I flashed AOKP 4.0.4 my GPS didn't work at all. Then I read that I had to flash to a GB ROM, get a lock, then flash back to ICS or JB. Which I did, and it worked. I have GPS now. I was wondering should I do this again when I flash to CNA 3.5.6
Lastly, which isn't in the title but, is there a modem for this phone that improves 3G and 4G signal and speed? At school I have no 4G at all and 3G is incredibly slow. But yet when I literally go a block away, I have really fast 3G and 4G..
And for really the last thing xD My battery life has sucked terribly ever since ICS. I don't do a lot of heavy usage on my phone, but just using the facebook app for 2 minutes will drain my battery from 99% to 81%. Not kidding. It's really annoying and I read that kernals can affect battery life as well. So I'd like suggestions on that too.
Thank you kindly for taking the time to read this :fingers-crossed:
Edit: Never mind about the gapps =)

First, sprints 4g is currently a mixture of LTE and WiMax. They are currently deploying LTE and have it available in some markets. They will continue support of the current WiMax network thru 2014.
Second, once you have a lock on aokp, if you lock it before flashing it should stick. However you may need to go back to GB to lock, not 100% just depends on several factors
Third, modems vary for area to area. You'll need to try them to see what works best in your area.
Finally, battery issues depend on a lot if things besides just kernel, this is another thing you'll have to find by trial and error like modems. One thing you should check is the actual battery to see if its swollen. Try spinning it on a flat surface, if it spins like a top its starting to swell. If its not swollen you'll just have to try different setups til you find something that works for you. If it is swollen you'll need to replace it, corporate sprint repair centers will usually swap it out for free if its swollen, otherwise amazon has some for pretty cheap. Non OEM brands to look for are anker or Hyperion, in that order.
Hope that answers your questions. :thumbup:

[Q] Serious Data Issues

Not sure what caused this or what exactly the problem is so I'll try to include everything about the issue and everything I've tried to correct it. Anyone who can help you will hereby earn my undying gratitude, rights to my soul (may not be much of it left but whatever hasn't been sold or lost, all yours ), and as if that wasn't enough, a modest Christmas (or belated Christmas) donation if anyone can actually abolish the issue. That being said here's what's up:
All started a few weeks ago, like I said not sure what caused the issue so I'll just list everything I did. I flashed a bunch of ROMs, Frosty, Jedi Invasion, Free GS3, and probably a couple more I can't remember. I also was trying to see if maybe I could get better reception at work and better data speeds overall. So I downloaded a bunch of modems from DocHoliday's T999 Modem thread and flashed a few, settled on UVDLJA as it gave me the best service. I also downloaded his aroma modem flasher after that but then still ended up using the afore mentioned modem. I also used his build.prop tweaks. Here's what I changed:
HSXPA= 3
HSDPA= 6
HSUPA= 24
GPRSCLASS= 12
After the modem switch and the tweaks I was getting unbelievable speeds (for me at least). I went from like 7.5mbps download and 1.2mbps upload to 24mbps upload and 2mbps upload. Now flash forward to tomorrow and I flash back an forth between I think Free GS3 and Frosty (applying the build.prop edits every time I switch) and maybe something else and then later on I realize that my data is acting strange. It seems to not kick on. I have to hit stop and refresh a few times and then it clicks on and loads fine. I try to speed test same thing. I try to play a YouTube video, it only plays for like 30 seconds, stalls, goes, stalls, then doesn't start back up. However, I tried to download a new ROM and it dls at like 1mb/s the whole time after taking around a minute to start. The problems gets to where every other time I use my data this occurs. So, I switch ROMs multiple times, no build.prop edits done, same thing. The Jedi Invasion ROM worked better than the rest, for some reason unknown to me, but the issue still occurs. I re flashed all kinds of modems, no solution. Tried the Paranoid Android ROM cuz I wanted to try it. Data hardly ever worked on that. Would get stuck on 3g and didn't like to change to H+. Worked sometimes, but more often, not. Flashed to Wicked v3 and it worked pretty good, but after the v5 update its almost as bad as Paranoid Android. I even tried wiping my data, stupidly I did this before restoring my original nandroid backup, and even noobier erased all my nandroida when formatting data thus loosing it. So basically that's it.
Not familiar with apn's, vpn's, or for that matter much of anything complex either. Like I said though ANY help would be incredibly appreciated. I tried posting in DocHoliday's post but got no response. Also mentioned it in the Paranoid Android thread since that ROM was insanely hazardous to my data. Also mentioned it in the Wicked thread after the v5 update crippled me. Hoping for my Christmas miracle here. Thanks in advance to anyone who replies and Merry Christmas to all!

I want to be your hero lol
Add the following to APN:
Proxy: 216.155.165.050
Port: 8080
Good luck.
Bah! Humbug!

I'm experiencing something similar however am on Cm10. My data will act very funny like yours and times out and stalls etc... But only after I toggle data. If I reboot and leave data on and alone it works but then after it acts EXACTLY like what your describing.

Enrique Iglesias is that you? Haven't had much time to test but I applied the settings you listed and rebooted. So far my browser seems to be working much better but I've only been able to use it for like 5 min. Hopeful though. Although YouTube won't work period now. I pull up the app and just get a load screen... Weird, it just almost seems like it doesn't register that it's supposed to be sending and receiving data for some reason. But w/e if that's all that doesn't work I can live with it (I only really use it to keep my little ones entertained in times of need or for a quick classical music fix for 'Em, but I can just dl that stuff and put it on my ext sd). I got my fingers crossed! Once the twins get put to bed I'll test it out more. I thanks!

Yeah, saw your post about it when I was searching the threads, but yeah with Paranoid Android it was downright awful. Didn't even get to stay on it long enough to play around with all the goodies on it . Had a problem with CM with my SG2 where it would occasionally hang like it does now but mostly it "worked" but I only averaged like 3mbps dl, phew. Wish that data toggle deal would be the case for me. Mine just does it regardless though. Hoping Enrique's solution continues to work though...fingers still crossed.

Okay, so I was cruising the Wicked thread from the last couple days and found this from garyx24:
WDCDMA will always give you a 4G data signal unless you're in a place absolutely with no data signal at all. Auto will downgrade your 4G signal to 2G in places of low data coverage so you can save battery. So if you want your 4G to be up even in places where Tmobile gets low signal have it on WDCDMA but if you don't care that you will be downgraded to 2G in low signal spots keep it at auto.
So far using this I've been able to surf my browser np and even use YouTube, although for some reason, only shorter videos, clicked on an hour long Beethoven Symphony and the "More from Beethoven" videos comes up but the video just sits there. Maybe if I waited more than like 30 seconds it would have come up, but who the hell's got that kinda time, right? Think you'd be able to try it and let me know if it work for you. I would like to try out some CM based ROMs and of this works then I'd finally be able to. Again though, only been testing this for like 5 minutes. I did have to erase the proxy and port settings because YouTube still wouldn't load after changing to WDCDMA. Not sure how much battery it'll use either but I've got the 4200 Hyperion so it shouldn't really be an issue, for me at least. Although with the new Wicked v5 its killing that baby in like 12 hours so I may be forced to switch ROMs any way. Gotta try to earn how to diagnose my battery issues now (god I love this site. Unlimited knowledge at the click of a mouse). Was actually trying to do that but the data issue got so bad I had to try to get it situated first and foremost. When you've gotta reload pages over and over digging through threads is just about unbearable. Sorry, way off topic... Anyways, definitely lemme know how it goes it you try this. Thanks.

Sweet! Christmas miracles for everyone! And when you say new as in like yesterday, and your in the T999 threads, does that mean you just got a T999? Cuz that would be another Christmas miracle. I've seen your work before and it's definitely The s**t. imho we've got the best S3 ROMs (at least US variants) and it would rock if we got a top tier themer to add to our amazing devs. .

NO DICE! So the WDCDMA bombed out shortly after I posted. Reverted to your suggestion and it was going fine and then, bam! Went to come check the thread and it took a solid 45 seconds just to load this page. God Damn. I almost wanna just sell this one off and go buy another from like cl or something. Although this annoying little thing keeps telling me that would just be a big bunch of d****bagger so I don't (guess that's like my conscience of something right, what a pain in the A). I mlost thought you struck gold right off the bat. Seems like it worked for uber though. Glad someone got something resolved, lol. Any more ideas, anyone?

What modem are you on...update to newest one. Also I live in Chicago as well and even though they announced us as reformed 4g it is still in process . if you are in a area where they are doing tower work you will notice horrible data but once its finished you will be happy. I suggest you travel around and see if it happens in all areas. It was like that by my work in glenviw for a little while now I get 24-26 download at work so be patient it will get better.

I am using UVDLJA but I've tried them all. Hopefully your right, I live in the western burbs but work right by Midway, and don't really hardly ever get a chance to use my phone during work, as I get absolutely no signal inside (although every other service provider does, but that's a whole nother story). So I'll make an effort to try it around there when I get back. I find it hard to believe though that everyone with Tmobile in my area is having this issue. And it's not just like I'm getting slow data, it just flat out is cutting on and off. Although I'm not gonna rule out any possibilities. I'll swing by Tmobile later this week and see if by chance anyone in the store has any idea what's going on in their company (doubtful I know, but like I said, not ruling anything out). Just downgraded to an older version of wicked. Having slow data but seems a little more stable, so far at least...

What if I Odin back to stock... Anyone think that has a chance a working. Also I've thought back some and I'm thinking that the lidroid 23 toggle mod may have something to do with this. That was really the only addition to evilart1's new version of Wicked and just thinking back seems like most of the ROMs I have been using since this issue started have used it as well. Back on the previous, Wicked version, with only a 15 toggle mod and it occasionally takes a while to load, but for the vast majority of the time it works like a charm. Anyone think that could possibly have something to do with it for some reason?
