Not really, never even thought about disabling LTE before I read your post, but I had found Tab/List view feature for the System Settings after I started monkeying around with phone, got it on Monday BTW...
When you have the System Settings open, tap the menu button to select between list and tab views. I like list because it puts most things in order similar to my ol' Samsung phones. :good:

Still no LTE option
Are you sure you have bought Samsung Note4?
Sent from my SM-N910V using XDA Free mobile app
Does your mobile operator has LTE? Usually you don't see LTE option when your network doesn't support LTE.

Try this way (ROOT is required):
- Install ES File Explorer, open the menu and enable Root Explorer option.
- Locate the file /data/property/persist.radio.lteon
- Open that file, and change its content from false to true
- Reboot the phone.
Hey Jusho,
I'm having the exact same issue with your issue, no LTE option with TELKOMSEL. Have you fixed your issue? If so, how?
Did you purchase 910G in Singapore?
I went to Singapore recently and was able to go to Samsung Service Center... we tried a couple of things :
- Use M1 USIM card in MY Note 4==> LTE option appears
- Put my TELKOMSEL USIM in THEIR Note 4 ==> LTE option disappear from THEIR phone
- Put OPTUS (Australia) USIM in MY NOTE 4 ==> LTE option appears
Today, I went to Grapari and asked them to replace the USIM and tried with the local Samsung Store :
- Put TELKOMSEL USIM in their Samsung EDGE ==> LTE appears
Any idea?
Hey guys, I had that same problem on my galaxy S4 before. I used a Straightalk sim card running on Tmobile. I called straighttalk and they replaced the sim card and everything worked.
Call your providers and ask them to change your sim for LTE compatibility. That is if your providers support it, and your phone supports the LTE bands.
Good luck

I did mention that I have replaced with the new USIM (4G card) and LTE option won't appear. And yes, my provider supports LTE Band B8/900 Mhz

4G not connecting

Hi,
i experience a problem on note 4 where despite LTE/WCDMA/GSM (auto connect) is selected, the phone reports only H+ instead of 4G. is there any suggestion on how to make it connect to 4G?
some hints:
- the phone is running stock rom , not rooted.
- no issue with 4G coverage. other phones in the same area are registered on 4G network just fine.
- same carrier between phones.
waiting for your input and thank you for your time.
Thnx

Your SIM card is already a 4G SIM Card?
My phone could get a 4G in the 4G area, but I don't have the option LTE/WCDMA/GSM (Auto Connect).
But in a non 4G area.. it changes to H+

No 3g or 2g after *#*#4636#*#* Radio Band selected

Hi guys...
Could really use some help here...
I was facing some issues with my 4g network... So I went to the *#*#4636#*#* menu and turned off radio etc...
I usually did this when my 4g network would give me problems.
However last time I had some time in my hand and decided to see what other options are there. SO I went to the Radio Band option and I don't remember what I chose but ever since then my phone can detect only 4g on either sim. No 3g no 2g.
I went to the radio band menu again and have tried selecting all options but nothing seems to work... I get USA band and then BAND MODE 31,32, 33 all the way up to 42...
Please help me...
I am new to posting in the forum. So I can't figure out how to attach images.

i had this problem i was also playing with the radio bands in the service menu follow these steps and surely you will get 2g coverage.
1. make sim 1 and as primary and then open service menu by *#*#4636#*#*.
and then select radio bands from top right corner and select radio band 42
2. now switch the sim cards in the sim slot and repeat the whole process from step 1 surely you will signals on both sim.

Switching betwen 2g/3g/4g

Hello
I'm with Leeco Le Pro 3 AI with stock rom 5.9.026s
I notice that my battery drops almost 25 % per 10 hours . Battery used when phone is idle - 30%. The reason for this as I think is that the signal in my place is not so stable so the phone constantly changes between 2g/3g and on some place in 4g.
When I go to settings / Dual Sim $ mobile networks / Network mode i see that it is on auto - ( 2g/3g/4g ( auto) ). The problem is that I can't set it expressly on 2g. There is no option on this settings to choose the type of signal.
If I click on Sim Card slot 1 ( I have only 1 sim card on my slots ) and next click on Netwrok Carrier there is 2 options - auto select and Search for Network. When i go for Search for network i found my local network signals and it shows 2g 3g 4g ... I choose 2g but this do nothing. The phone again is in auto mode ( 2g/3g/4g ( auto) )
So does anybody has any idea of how to expressly set the phone to use exact network carrier ( in my case 2g ) not to be auto?
I believe you can force certain bands by typing this into the LeEco dialer: *#*#4636#*#* and choosing "phone information". Select "GSM only". Use this with caution. Your SIM might stop working because your provider might not support 2G only.
I thought there was an option to choose 2g 3 or 4g separate ???

IDK. Just chose GSM only if you want 2G only. Or better yet, pop your SIM into the second SIM slot and you'll only get 2G. Much safer.

AFAIK, it's supposed to give you a bunch of options: https://www.learn2crack.com/2016/01/force-2g-3g-lte-only-mode-in-android.html
Otherwise just choose 2G or LTE as your preferred network type in Settings.
Maybe try an app like this: https://play.google.com/store/apps/details?id=www.extremedroid.com.a4gltetoolkit&hl=en
sk8223 - my settings doesn't allow me to choose between 2g /3g or LTE it is locked on auto! There is no option on my model to choose network type.
Sweeden - I thought so that there is such option just as your screenshot but for Leeco Le Ai there is no such one.
Also there is no option to switch off sim card when you are with only 1 sim card. Actually there is an option - but it doesn't work.
So I will try some kind of app to switch between network type
Leeco Le pro 3 AI has really awful ROM- good hardware but the ROM is the worst I ever used
I badly need a custom rom for this model

Have you tried some kind of app that let you choose only 4G and that really works even after the restart of the phone ?

No I did not.. but as I see on this thread the link to the app it change the settings on the same place as the call combination *#*#4636#*#* ... So i suppose every app do the same things. But to use this code is not so bad ... from there you can choose, 4g it works!
The bad thing is that my issue with battery drain still exist so i will continue to investigate the problem. Phone in idle consume too much electricity - some **** app sucks my battery energy! Every day I have issue with this phone - it is so time consumption .. bug after bug

This works just for a moment for me! Any other tricks that can force 4G LTE even if there are no 4G LTE signal? Thanks
Edit:
Use this instead to force 4G LTE without the ROM changing it back to auto.

Select "Network Selecting" then change to LTE only. Don't mess with the others, I heard it might destroy your device.
