In low network connectivity areas Network Auto mode Switches to 2G even if there's Low 4G signal is available. I have tried Switching to 4G only Mode by using 4G Switcher App, But its not working.
If Anybody know how to switch to 4G only Mode on Galaxy J3 please let us know.

is there any way that you can disable 3g mobile data while keeping on the 4g data(like you can with the evo 4g)?
the reason i ask is this... i use my phone to tether to the computer in my room, and it seems that i get a weak 4g signal there, so its constantly going back and forth between 4g and 3g. I'd prefer to keep the phone only on a 4g signal, even if weaker. is there a way to do this ?
Try the app lte onoff from the market. I believe there's an option for lte only.
Which selection would it be? thanks in advance

I need this too.
On the thunderbolt if you used one of those phone info apps you had the options for CDMA only, CDMA/LTE auto and LTE only.
I have to use LTE only when I want to tether in my office because if I leave it on auto my phone will constantly switch between 4 and 3g and it rapes my battery.
If you use those same apps on the charge they show a bunch of gsm options and wcdma and such. Far as I can tell none of them do anything either. The built in options on the phone allow you to use CDMA only or CDMA/LTE auto but not LTE only. Definitely hope someone can work up a fix soon as it's a key issue for me (I own two tablets that I like to tether).
It's been good to me but does it work for you?
I remember doing this for a few other phones with good results.
Now I'm doing it with my Sensation and it looks like its working... but I want more people to test it. Test battery drain and data speeds.
Anyways,
Type *#*#4636#*#* in dialer > Phone info > Change WCDMA to GSM auto (PRL) and that is it. You should see the battery drain less on stand by.
post results here... and a thanks would also be good.
if you only use 2g,you can set like that

Yes, it does save battery. Same as going into Mobile Network settings.

GSM Auto (PRL): gives me 4G speeds
GSM only:gives me edge speeds
GSM Auto (PRL) isn't in the mobile network settings.
gsm auto prl will save the user a bit more power because it wont force the phone to continuasly hunt for a stronger signal
And just in case you guys want to play with some settings:
WCDMA preferred - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 3G is favored more.
GSM only - The GSM phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
WCDMA only - The GSM phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM auto (PRL) - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more. This one is a bit confusing to me since PRL is associated mostly with CDMA technology and not GSM technology.
CDMA auto (PRL) - The CDMA phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.
CDMA only - The CDMA phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
EvDo only - The CDMA phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM/CDMA auto (PRL) - Some phones are equipped with both GSM and CDMA capabilities. This setting appears to just have the phone attempt to stay connected to the data communication type that works the best. (Maybe the Samsung Galaxy S will take advantage of this???)
Unknown - If none of the above fit or the phone is acting weird as far as connecting to the carrier, you will see your preferred network type is set to this

So what's the downside? Edge speed more often? If there was no downside why wouldn't it be the default?
I find gsm auto gives slightly slower speeds in a speedtest than wcdma only... (only two settings I use) and that's it.

Hi there,
I have a Samsung Galaxy S2 LTE (signed with Rogers) and I'm trying to figure out how to disable 4G on my phone and only use 3G. I've looked through some threads talking about changing the "Network mode" in the "Mobile network settings," but I haven't had any luck with that.
GSM/HSPA/LTE (Auto Mode)
GSM/HSPA (Auto Mode)
GSM Only
HSPA Only
Right now, I'm using GSM/HSPA (Auto Mode) but it still says I'm connected to 4G in the status bar. In GSM Only, it connects to the edge network (E) and in HSPA only, it will connect to 4G network. Anyone have any ideas of how to connect using 3G?
Also, I've noticed in my APN settings, I'm using the "ltemobile.apn" (the only APN setting I have listed). I don't have a LTE plan, so should this be the APN that I should be using? Since I'm not on a LTE plan, would I be charged more for using the "ltemobile.apn" APN?
Thanks
4g is 3g/HSPA. If you were able to get LTE, the 4g icon would change (as long as you aren't on a ROM that doesn't have LTE icons)
Is there any way to turn off 4G/LTE completely and just use 3G to conserve battery life? I don't own a Skyrocket but my friend does and has horrible batt life.
On home screen press menu button and go to phone settings
Wireless and Network > Mobile Networks > Network Mode
Here you can tell it to use edge/3g/lte or edge/3g or just edge or just 3g
Hopfully that is not my ROM that allows me to choose that. Using Sky Ice Cream Sandwich rom
It depends on the ROM. Stock won't do it and a number of custom roms I've used don't do it either, but I have seen some that appear to allow for that functionality. Do some research and find one you like.
"4G" is 3g (well hspa+) which is twice as fast as what 3g speeds were originally at (see 4, iphone) its more of a marketing thing. There won't be a 3g icon showing up with these roms. best bet is to choose gsm/hspa then it won't be looking for LTE.

HSPA is actually 3G. AT&T and Tmobile were calling it 4G because they had to come up with some marketing scheme to compete with WiMaxx and LTE. SO in short, AUTO HSPA... is effectively disabling your 4G.
Hello, i bought metro pcs unlocked Galaxy J3 prime. My country's 4G band frequency is 3, when i turn on 4g its always edge, when i change band with service mode 4g works but disables phone calls. how do i fix it?
Hello,
i often have the problem, that 4G (LTE) is propably aviable but the signal is weak and the Mate 8 switches to EDGE but the 4G Signal is sufficient for fast speed internet and so on.
Now the stock ROM has only options to force 2G and 3G in the net settings but not to force 4G.
Is it possible per app or mod to get these option? Or better: is there a custom baseband version or modification for optimized 4G reception and/or that the Mate 8 accepts weaker 4G signals and doesn't switch back to 2G/EDGE?
Thank you.
