Any way to force LTE only on Samsung Galaxy S III i747?

Hi Guys,
I have LTE coverage where I am, but phone keeps going to 4G.
Is there any way to force it so it stays on LTE?
I have tried the following app but no luck. Once I select the LTE Only mode it switches to WCDMA Preferred mode some how.
LTE OnOFF - HTC Thunderbolt, https://play.google.com/store/search?q=lte+on+off
Any way, any idea any one??
Thanks

If it keeps dropping back to 4G then the LTE service probably isn't strong enough where you are. You can't just force it on either. That's like forcing any service at all in the middle of the ocean.

Previous poster is right.
But u can play around. Reboot to recovery, wipe cache, reboot. Flash different ROMs, usually one Stock based, another AOKP - I believe modems are vastly different there.

The only way to fix this is make a new APN there's a post on skyrocket fourms that shows you how

I have done forcing on other devices such as Galaxy Nexus, currently using Sierra 754S that has feature where you can force it to stay on LTE, and it stays put.. Only problem it gets WICKED HOT if I pump a lot of data

Assuming you subscribed with your provider for LTE-service, then definitely it's because your LTE coverage is not great.
If you've never seen your phone connect to LTE before, I suggest you contact your provider and make sure you are on their LTE-network.
LTE-device doesn't automatically mean you're getting LTE service. I've seen people make that incorrect assumption.

Well, all you really need is LTE Sim card for AT&T, it works awesome ... as I said it works great with Sierra 754S air card.
So any device that has LTE capability it works perfect with that.

No voice coverage on Lte so the phone still needs hspa to make and Recieve calls and text messages. Until all the voice over Lte and hand off standards are in place Lte is a data only feature.
On a data stick it makes sense to allow an Lte only mode but on a phone it would not be a good idea.

Disabling LTE (saves battery?) Easy on GS4

Not sure if this was posted already but looking through the menus I found how to easily disable LTE. It's not around here and I read having it enabled eats battery. My HSPA speeds are 5-10 megs which is more than enough for what I do.
Anyway:
Settings
Connections Tab
More Networks
Mobile Networks
Network Mode
Choose GSM/WCDMA (auto connect). 2nd one from the top.
It seems this device sucks up battery at twice the rate of my former Note 2. Maybe this will help.

My battery has been pretty decent for the past two days, but I'll try this n see if it gets better. BTW, anyone can show me a pic of their home screen that has the 4G lte icon?

It just says 4G when you have LTE on the Galaxy S4. At least for Sprint anyway. I use Cyanogenmod so mine does say LTE. For AT&T I know for a fact that it says LTE on the top right of the 4G icon.

Got rid of LTE on Note 2 ATT...:)

i use Menu Code *#197328640# to get rid of LTE on my Note 2. The option to switch to 4g only came on version 4.1.1. now its permanently off from the phone... no matter how many time i restore my phone.. :laugh::laugh::laugh:

I think some people are too obsessed with this notion of battery life. Sure, LTE might degrade it a little, but is it really worth disabling completely? I'm sure I wouldn't, I want the full features of a phone, whether that is data speeds or other features. Unless you don't have a LTE plan, then I understand completely.

I think that's backwards move there! Because I love my LTE speeds I get, almost faster than some WiFi at home!!
If you don't want lte speeds, then don't get a LTE PHONE!
And another thing if your really concerned about battery life then purchase a extended battery! They start out at 6200 mAh, 6500, 7600, 9300. Don't think they'll have to worry about battery life with one of those!:thumbup:
And tons of external back up batteries also. I have a16,000 mAh backup battery

Just so you know, messing around in that menu can also stop your SIM card from working! Phone nit getting no signal, not connecting to network! If you end up hitting the wrong buttons! Fyi

I disabled lte as well, since hspa+ is plenty fast around here I just select wcdma all.
Automatic can drain battery if you're in between two towers, like I am.

Isn't there a option in settings > mobile networks that you can choose to do it very fast?

Ya, I have the menu option in <mobile networks>. I turn off lte if I'm in an area where it keeps jumping between lte & hspa and it can save me 15-20% battery over an 8 hour work day.

Is there a way to permanently disable Edge? That would prove more useful for me.
Often time, there is a "4G" signal nearby but for 10 seconds I switch between Edge and HSPA I loose data connectivity.

As noted before, this will not work if you are on AT&T as it is RAT restricted.

"Death Grip"?

Hey guys, Not sure if this is normal or not, but in my house I get 1 bar signal with the phone bare and laying on the table. If I put my case on it (Spigen Slim Armor View) it loses that one bar. (without case I get 101-DBm, with the case it jumps to 109-DBm or so. I thought it was the case at first but than I remembered the "death grip" so I put my hands on both sides of the phone while it was laying on the table and it lost the bar from my hands covering the sides.
The case i have can be taken apart into three pieces. I stripped it down to JUST the TPU part and put that on the phone, and it still loses it just with the TPU part of the case on it. Originally I figured I'd just get a different case to use at home where I have low signal but it seems I can't even use a regular TPU case without it dropping the signal...
Anyone else in low services area's experiencing the same?
(Note: I have a T-mobile S4, but its unlocked and running on AT&T's network. Not sure if that matters but I figured since the phone itself is T-mobile I'd post here)

Do you get 4g lte or just 4G/hspa?

seeming you only get 1 bar in your house, i would assume any little thing would disrupt your 1 par, since its so weak in the first place. This is the reason why i love wifi calling so much because if i didnt have it, id be in the same boat as you

Yeah Wifi calling is cool but I don't make many phone calls anyway, the only problem is the 1 bar of signal is enough to receive text messages. If I have my case on and it loses that 1 bar, I get text messages about 45 minutes after they're sent to me. Which is really annoying since I hate leaving my phone bare in order to get my texts on time... Guess that's the price I pay from going to AT&T from Verizon network.
Their coverage map shows "Good" at my address (Which it is, OUTSIDE) but inside any building its garbage.

your building is just probably old and is made of something that significantly reduces cell phone signal. ANd you do know, that you can send and receive texts, mms and all that jazz with wifi calling too, its not just for calling despite it being called that

Unfortunately not, the building is 4 years old. And it happens in all the buildings in my area, restaurants, walmart, neighbors houses, etc.
And I didn't know that, however I'm on AT&T and they don't have it. Maybe I'll give T-mobile a shot but their service in my area is even worse than AT&T lol. Do they do Wifi-calling with Pre-paid?

I'll look into a repeater. However I'm still young and my credit isn't very established yet, and I hear AT&T usually requires a lot of money upfront to start an account. (I use their prepaid $60 plan currently)

I see, however inside my house I don't get LTE (well it goes in and out, but the speeds are like 1mb down and 0.50 up when it does connect) So should I continue to keep it on automatic at home? (Data doesn't matter though, I run on Wifi at home, its just signal strength that I need increased so if the LTE/GSM setting is best for better reception I'll keep it on that at home anyway.

Has anybody tried to disable bands before, same issue here, no ounce of lte unless i update PRL/profile which only last a few mins.

All I can say is be patient. I had the same issue for a couple of months where I had to cycle airplane mode (or update PRL) to get LTE then promptly lose it. Disabling bands 41 and 26 helped. But after those two months, LTE works great most of the time without doing any of this.
Sprint is likely working on towers in your area.

Sprint has been "working on towers" in my area for over a year. Every time I go into the Sprint stores to ask when LTE will be here its always the same answer: 'Well they are actually working on upgrading the towers right now, so if you are experiencing issues with data connectivity or slow speeds thats probably why. They expect to have LTE fully up and running in 1-2 months'. And as of today, still no LTE. And 3G speeds that are so slow it wont even register on a speed test.
http://newsroom.sprint.com/news-releases/sprint-celebrates-americas-newest-network-with-a-satisfaction-guarantee-offering-wireless-users-a-30-day-riskfree-trial.htm
Click on the link and read the section about 8T8R radios. So basically before Sprint brings LTE to all of its customers they started introducing Spark in select areas. Then also before completing their LTE rollout they will be upgrading the Spark towers. Even after LTE is installed it consistently tests the slowest of all 4 major carriers. And as more people buy phones that are LTE/Spark compatible, it will only get worse.
So yes it is good to be patient. But Sprint's upgrades and improvements are very slow coming so don't hold your breath.

I like it
Lets me know how network is going

Freaking hate Spark. Glad to find this thread... I disabled the two bands and it's MUCH snappier now... Is there any reason I will need to re-enable these bands?

You'll want to reenable those bands unless you want a device that only works on 1/3 of the spectrum that Sprint has in the market. I can see disabling those bands during the upgrade process if you are having difficulty but with a finished product, I can't think of a single reason why you would ever want to disable those bands.

Yeah it's serious, your phone may have a different behavior than the LS980 due to the service provider unique tweak to stock android on your phone. Once the LS980 hidden menus are unlocked using the SPC code, the bands toggle no problem. Maybe that could be your issue, if it's not, that's why I suggested to find a thread related to your phone. Good luck!
