So I'm at school where fortunately we have lte, but lately my phone only connects to 3g unless I reboot while in campass. But even after class I go back outside and have to reboot again to connect to lte. Anyone else have an issue like this???

I'm having the same issue.
Full LTE available at work. Some days, it's stays on 4G throughout my entire shift. Sometimes when I use my phone for daily tasks such as web/sms/calls it drops off to 3G and stays there til I reboot then 4G comes back again. Strange.
Are you running CM or a TW ROM?

Is your Sprint Optimizer on? Also you might get more responses asking in the LTE thread in the stickies in General.

I'm on Android 4.2.2, running the new Liquid ROM. Only uses 3G, and same with android 4.2.1. When I switch back to 4.1.2, 4G WORKS
By the way it's a T-Mobile Galaxy S3, any help?

Do something to use data, like browse a page or download an app... Does it switch to 4G?
Are you on the latest modem?

This is stated in the OP for the Q&A for that ROM. You still get your 4G speeds, it will just show as 3G, H, or H+. Did you do a speed test on your data connection to see what speeds you were actually getting?

No, the OP for the Liquid ROM he said he was using.
Thank you! I downloaded the latest modem from DocHoliday and it displays 3G only when Data isn't used, but when data is being used it shows as H/H+.

What do you mean by reduced cell service? Like no 3g/4g/LTE or just spotty?
If you're only getting edge, check your IMEI

I apologize i should be more specific. I am getting lte most of ther time because my area has strong lte. Also great speeds. I ve noticed though in traveling short distances from my home..places where i normally get strong lte, the connection switches quickly to all different modes then back to lte. Also i usually get more bars where i am. Not sure if its the rom or a google issue...

Hey guys this is actually my first post and I am still somewhat of a noob when it comes to rooting the android system. I recently rooted my GS3 on AT&t and I'm sorry if this has already been posted about, but I need some help. Every ROM I have tried which includes paranoid android, CM, and a handful of others I can't remember the names of off hand all have the same issue. Whenever I go from basic 4G to 4G LTE I loose my data connection. When I go back to basic 4G I have to restart my data connection to reconnect. The ONLY ROM I have found that doesn't have this issue is the Synergy Touchwiz.
Am I doing something wrong?
Thanks again for any help and again I'm sorry if this has already been posted about.

check your apn settings
OK so I just checked my APNs and just ATT was checked. I switched it to ATT LTE. We'll see if that works and if not I will check again.
Thanks

I keep getting "Connection timed out" errors while trying to open Google Play Store on Sprint 3G in Manhattan.
I decided to run Speed Test app, and I'm seeing 83ms ping, 492 kbps download, and it's been sitting here waiting for upload the finish for the last 5 minutes. It's currently zero.
I'm also having issues with sending Gmail's, obviously because I have no upload capability.
Apart from the crappy Sprint 3G service (which is astounding in Midtown Manhattan), are there any other setting I should be looking at ?
I'm running Elemental X build 3 with KT747 5/29 kernel. Baseband MD4

Could be worse signal than ever due to tower upgrades on Vision Network. I hear NY is being worked on at this moment.

Seems like they're working on it big time. Well at least according to THIS map.
There's an issue when LTE is enabled and you go from LTE to 3G and something gets fouled up leaving the data borked until you cycle airplane mode or reboot. I've read if you keep it in 3G/EVDO mode, there aren't any issues.

The only roms with issues handling the transfer between 4g and 3g are AOSP roms. Touchwiz roms do not have this problem. But when Network Vision was being updated and brought online in my area I went through very similar issues. At times where I normally got good 3g, I was almost getting no connection.

Yes the signal gets all weird when they're working on an Update in an area. They are still working on it here in my area. Sometimes it will go to pot for most of the day. The upside is that they are working on it.

They are on an aosp build. Says they are running elemental x, which I thought was a varient of aosp, but I'm a noob to sgs3 so I could be wrong...
I am having a similar problem on aosp where I can't connect to the play store. It times out and it doesn't matter if I reboot the phone, turn off data, or cycle airplane mode. I can access the web fine and do other internet based stuff. TW Roms in the other hand work fine. I've updated my PRL and my profile. I'm up to date on my firmware (as far as I know..like I said, I'm a noob to the sgs3). Can't figure it out. ..

Hey all, I'm at my wits end trying to figure out what's going on with my phone/service. First off I hope this is the correct forum since none of them officially address the US Cellular version of the S3.
So what is happening is that my device seems to only want to connect to 3G. I am running the latest nightly for CM 10.1. It all started last week while I was in the twin cities on data roaming for a few days. On my drive back to Wisconsin I notice I would go in and out of 4G service.. by the time I hit home I was on solid 3G service. This was last Friday. I knew there was some work going on the towers in the area as my brothers 4G service started working on Sprint. I just assumed it was something to do with that.
By Sunday and still on 3G, I called tech and they did everything under the sun to try to get me back on 4G to no avail. They ended up sending me a new phone. When the new phone arrived on Tuesday I did a factory reset on the old phone just to clear everything before sending it to them and I noticed it went back on to 4G. This was on the stock ROM, rooted still.
So I switched the phone over to the new one and sure as hell, comes up in 4G. I replaced the recovery and restored a backup I had.. phone pops up.. 3G. :crying:
I did a factory reset a few times and nothing.. still would only come up in 3G mode. I then restored a backup I had for the stock ROM and what do you know.. 4G. Flashed a fresh download of the stable 4 snapshot.. 3G.. then I did a factory reset and what do you know .. 4G.. reboot the phone.. back on 3G.. Tried AOKP.. 3G..factory reset.. 3G.. Back to CM 10.1 nightly.. 3G.. factory reset.. 4G.. reboot.. 3G.
I cannot figure out what the hell is going on.. it clearly isn't hardware as it's now happened on two phones. I thought it might have had to do with being on data roaming for a few days so I waited until the data billing cycle finished (the 6th) but no luck.
I'm at wits end.. I will try anything at this point to get it working again with CM/AOKP.. doesn't matter.. just want my 4G back!
Your phone does not have 4G, It has HPSA.
On AOSP/AOKP, your connection will show up as 3G until it's being used. Let's see some speedtests.
Don't go by what it says in the ststus bar. What does it say inder Settings > About Device > Mobile Network type?
Now go start a large download, like a rom or something. While its downloading check again and post what you see.

Speeds
Thanks for the quick responses guys..
First thing was my status bar was showing 4G for about a year.. it was just recently I started having the issue. I used to get about 20Mb/sec down and now I'm getting about 800Kb-1.5Mb. It's clearly much slower than it was.
And the network type is CDMA - EvDo rev A:6
Try going under Settings, More Settings, Mobile Networks, and try a different network mode.
Sent from my SGH-T999L using xda premium
Its selected as LTE/CDMA/EvDo. The only other option is CDMA/EvDO. I think it's set correctly.
What about Network Operators? Have you tried checking or trying a different one?
Sorry, I just don't know much about the usc model.
What is the model# btw.

Not sure what you mean by network operators but the CDMA subscription is set to RUIM/SIM (which it should be) and the System Select is on Automatic and not Home Only.
Model is SCH-R530U
Under mobile networks you can manually search for and then select an operator.
Judging by your model number, you will likely find more and better help and probably others with your phone in the Verizon forum. (Possibly Sprints, but most likely Verizon)

Thanks. I think I found the answer.. some code in CM 10.1 was causing the NV to lose it's information. A code change was put in to prevent that from happening.. I just need to go back to stock and flash back to CM.
Thanks for the help guys!

Everything I've read involves going back to stock, factory reset, and reflashing. Is there any way to resolve this without reverting to stock? Or is that the only way? - Does it need to be unrooted? And also, one thing I was curious about, I have a stock backup, would flashing that, and then reflashing to a current CM backup do anything, or does it need to be a clean flash?
I would go totally back to stock and start over. It wouldn't even take more than an hour to do everything.

Yup, if you're having problems, taking shortcuts often result in more problems and more time involved than just starting over clean.

I was having the same exact issue on CM10.1 RC5 -- called US Cellular and eliminated everything but CM causing the issue. Flashing back to an earlier version of CM, trying RC2 first.
Do you have the SCH-R530U? If so, see my quoted post below.

Verizon has their own separate forum and you can get to it from the main forum page. Go into q&a and use the search this forum searchbox.
I'll try to get the link in a bit. Bout to leave for a while though.

Went the revert to stock and reflash route. Issue is resolved. I did have to do it twice, as after the first reboot with RC5, I lost 4G again, skipped it and am running the 6-19 Nightly and have had no further issues! Thanks for your help. You guys are awesome!
