Force LTE? - Droid RAZR M Q&A, Help & Troubleshooting

Sometimes I drop to 3G in my home 4G area. Turning the phone off and back on usually does the trick but is there another way to keep the 4G connection?

I believe you can set the phone to only receive CDMA and LTE in the Mobile Networks option of the settings (in the more section)
You can also set it to receive only GSM, GSM and CDMA, or all available networks.

CDMA=3G, LTE=4G. Right? Since I am on the Verizon network, the only circumstances that I would connect to GSM is if I left the USA, right? I wonder if there's a way to isolate LTE connectivity and turn off 3G all together..

You on stock or a custom ROM?
That sounds like a radio problem tbh.
You can't use LTE only - in fact, LTE requires a CDMA or GSM base for stuff like phone calls so it always has to be connected to 3g or 1x.
There's a possibility that switching airplane mode or pulling your SIM out would force LTE to reconnect

Solution: Yes you can force lte
I'm not a engineer or a radio analyst but I do believe what the previous post says about LTE needing CDMA is completely wrong - it certainly doesn't need to have CDMA or any other radio band to effect LTE. That being said, LTE is BASED off of 3G CDMA. But again, I may be inaccurate, however I think the "proof is in the pudding"......HOW TO FORCE TO LTE (ONLY)
1. Open up your phones dial pad
2. Dial *#*#4636#*#* (An app with the title "Testing" should open automatically... but not 100% sure. If it doesn't open auto hit dial....
3. Select "Phone Information"
4. Scroll down the phone information page, you should see the first button that says "Turn off radio"..... We want to focus on the item right above that. By default it's set to "LTE/CDMA/EvDo/GSM/WCDMA"
5. Click on that which should provide a drop down list, with specific radio bands.
6. In your case select "LTE Only"
7. Profit!
FYI: IN "LTE Only" mode you will not be able to make or receive calls - this is good for DATA only. You can manually reset back to default mode but regardless every time your phone reboots it will go back to default.

Well yeah that's true. Not really sure if vzw will let you connect though. But yeah no calls or text

[Q] HSPA+ or 3g or 2g setting

hi i came from a mytouch slide and i was able to set the network to 2g or 3g or even both at the same time. is there a way to turn off 2g on the g2? or even turn off HSPA+ and only use 3g? i've been looking around and can't seem to find anything on this. i'm not rooted but if i need to be that will be fine.
Have you tried dialing#*#*4636*#*#?
Sent from my CyanogenMod powered G2.
Yes. The easiest way is to go to the phone dialer and type in:
*#*#4636#*#*
This will take you to a menu.
1) Choose "Phone Information"
2) Scroll down and there is a drop down menu.
Default is "WCDMA Preferred" --- Which is 3G/2G with 3G preferred.
You may choose WCDMA only for 3G only or Edge for 2G only.
I don't think you can turn off hspa+ but you can just go to settings ---- wireless--- mobile networks--- and just check 2g only for edge and leave it off for 3g/H+

... hspa+ ***IS*** 3g.... so you apparently want to choose between 3g and 3g? Can't happen.
it can be done but requires a reboot. You will need to add/change the setting "hsxpa=0" in the build.prop. this will remove the "4g" also you may need to change lines that referance the ril libraries to remove the reference to "rilswitch". But that might just be with cm6...

Network Mode - Verizon

I noticed that by default this phone is setup to use "Global" as the preferred network mode. I'm thinking that means it'll try to use CDMA, LTE, and GSM networks. I noticed there's a setting for "LTE / CDMA" and I'm thinking this setting may save some battery because the radio software wont try to use the non-existent GSM for Verizon.
Anyone play around with this setting and notice a difference? I just switched to LTE / CDMA. I lost data until I rebooted and now everything is working fine. It's odd that it was set as Global to begin with.
I did the same thing you did. I notice no difference but it does work fine. I also tried fooling around with lte on/off app. Is there a simple widget that can be used to toggle between 4g and 3g? If I know i won't be using the phone for a while i would like to switch to 3g to save battery.

You can download an app called Phone Info -- open it up and go down to Network mode, select CDMA (Auto) that will force 3G only.
It will remain until you reboot.
I used to do this with my OG HD and it did save quite a bit of battery but in my semi-scientific tests the difference on the Maxx HD is almost nonexistent, certainly not worth the reduction in speed or the inability to use data and voice simultaneously.
I don't know if you noticed but, data and voice simultaneously is possible even in 3g mode with the razrHD Max. The greatest android phone verizon has ever offered.

How to force LTE/GSM/CDMA auto (PRL) or any other Preferred Network Type.

Hello, I have no problem receiving an LTE signal on BCE (Canada) through the Phone Info Menu. I can select any of the preferred network types including LTE, LTE/GSM, CDMA, LTE/GSM/CDMA but it won't stay. Every day I have to go back into the menu and it reverts back to the first selection "WCDMA".
Does anyone know how to force this so it stays on LTE/GSM/CDMA. So it will stay on the LTE-enabled network unless there is a loss of signal and it reverts back to HSPA? It does this automatically when "LTE/GSM/CDMA is selected, but again reverts to CDMA within a day usually.
I did some searches here, but 99% of what comes up is just people asking how to enable LTE or if their network gets it?
Any ideas? Maybe some sort of macro thing.
Regards.
Add this line in build prob
telephony.lteOnGsmDevice=1
Save
Reboot
Now in settings/more/mobile networks u will have an option to choose and it will stick. U have to add the line every time u flash ROMs.
But I keep iron WC DMA/gsm for better battery speed is OK on h+
Thanks for the helpful reply man. I haven't edited a build.prop yet, so Ill have to check it out.
Alright thats all done now, works like a charm. Like that I have the option now either way. I typically stick to WCDMA/GSM when on the road or at work where LTE is spotty, but on days off for around town I would rather just be on LTE as I usually just looking up something quick when Im shopping or something.
Thanks again.

Nice
I keep it at LTE, it does have less bars but quality is same for me, speeds are amazing. Also 4G is only data, not voice, so when u have an active call it will change to 3G.(but that's not the phone it's the network)
don't forget to do it again if you flash new ROM, also Tethering WiFi won;t work, there is a fix but it's complected for me, so I just go to W/G if I need to share connection.
So, my Nexus 4 shipped today, and it'll be in my grubby little hands by tomorrow evening. I, unfortunately, can't activate it until March, as I have to wait for my Verizon contract to end, but I keep seeing this LTE stuff, with no real explanation. I do know that the Nexus 4 has an inactive LTE radio in it, but what's the use of activating it, if T-Mobile doesn't have LTE? Is this only for the AT&T users?

There are other threads dealing with who can access LTE in the USA. I am in Canada and on Bell.
I'm in Canada, using Fido. I activate the LTE on my Nexus 4. It works fine, but I'm not able to share internet with wifi hotspot.
I have Android 4.2.1 (latest OTA from Google).
There is a bug with this version or it's only because I activate LTE manually ?
As per the previous comment:

I'm with the original firmware. Android 4.2.1

i recently got a rom from revolt on my n4 and i switched cdma to lte gsm wcdma auto
i also went into build.prop and wrote down telephony.lteOnGsmDevice=1. i went and to setting, more, mobile networks chose the correct setting. so now i got 4G. great i can make calls. GREAT. but i cannot receive calls...
need help with this. im really choked about this ROM
Even if I select "LTE/CDMA" in the Mobile network settings menu. The settings page keeps displaying "CDMA preferred".
Does this mean it didn't work? In quick settings, I see my mobile data connection as 3G Bell.
LTE only seems to work when using the *#*#4636*#*# trick in the Phone app.

Would you have by any chance the line for the built.prop to stick the setting to GSM Auto (PRL)?

Thanks, but LTE doesn't work in my country, its always stick on lte/gsm/wcdma but it doesnt detect my gsm so i have to manually set it on GSM only but wont stick here every time i restart my phone i have manually set it on GSM only otherwise it wont detect my network
Any advice ?
How can I make "WCDMA Only" the default selection?
Where I Iive there is no LTE and the coverage of the service is quite poor, so the phone keeps jumping between E and 3G/H. I have to manually go into the phone app and select "WCDMA Only" is there a build prop tweak to make the "WCDMA Only" the default option instead of "WCDMA Preferred"?
Thank you.
So is there a way to get the nexus 4 to work on Verizon ??

Aah Crap ! Well thanks man saved me from buying on guess i will have to stick with my rezound for now then
fixed it
For everyone still searching for a solution to this problem, this worked for me. Go to phone information and turn your radio off. Then switch to LTE/GSM/CDMA then power down, DO NOT TURN YOUR RADIO BACK ON. Now remove your Sim card, put it back in, reboot and you should be good to go. DO NOT HGO BACK INTO PHONE INFORMATION OR ELSE IT WILL NOT STAY
If it still isn't connecting try fiddling around with your APN settings.

[Q] Mobile network issues [SPH-L720]

I have been having substantial problems with my Spring GS4 connecting to mobile networks. I am in an area where I should have LTE, but most of the time my device constantly switches between 1xRTT and eHRPD (and NO network connection). Occasionally it will connect to the mobile networks 3G on 1X and 4G on LTE, but that usually requires restarting the device/ turning on/off airplane mode.
Any thoughts that you have would be greatly appreciated. I am happy to supply additional information upon request.
When you say 'should' have lte, do you mean Sprint had officially announced lte live in your area?
If not it's likely your issues are associated with lte deployment and are fairly common until upgrades are finished.
If so, if try prl and profile update

My area has an active LTE tower. I sometimes do connect, but soon after it goes back to no data.
I have tried a prl and profile update, although I will try again right now
Update: I did a prl update, but the profile didn't work (my device won't stay connected long enough for it to finish. Multiple attempts)

So what do you mean there is 1 tower in your area that has LTE? If that's the case it will be a while to get a consistent stable LTE connection because they would be doing NV upgrades in your area. And how far are you exactly from the tower that has LTE. It is probably just out of range or can't penetrate the walls or something. You should probably just go to s4gru.com and find your market thread and read. Also are you on a custom ROM. We can't really help without more info.

try a ##72786# reset(may need msl/spc) to reprovision your data profiles. I'd suggest being on wifi before you do this so that the profiles update over wifi after the reset. Do your PRL update over wifi as well.
It's possible that Sprint is in an upgrade phase which is causing issues. Here in philly we have many LTE towers yet my connection with eHRPD/LTE SUCKS!!! I know what bad is... this is worse than that.
You can get around this(YMMV) by setting the mobile network to cdma(cdma/evdo) instead of cdma/lte(cdma/evdo/lte) in settings. Doing this will make your phone ignore eHRPD/LTE and just stay on EVDO.
I read that ##72786# really screws up this phone on another thread
OP If you have NV upgrades going on in your area, give up on depending on your phone. I had to switch to Google voice just so I could find out if someone tried calling me because I would miss everyone's calls in addition to having almost no Internet.

Thanks for the replies u guys. Im guessing that in my case its an upgrade phase. I still get connections all over but it switches back to EVDO all the time. Ill keep u guys updated.
Update: been plugging in at different locations and lte is connecting. When I unplug shortly after back on evdo 3g. Does anybody think power management on a system level might be a culprit? Anybody having similar results?

2 Devices. One seems to connect to LTE better than the other. Same Place, Same Tower. One is stuck on 3g (or worse) as you detail above while the other is solid 4g. Data on/off cycle doesn't help. I was using RF Signal tracker to see tower, and network information. I have also had many dropped calls, as well as Bluetooth troubles.

phone just stop receiving any call but the signal bars are full

Anyone experienced that the phone just stop receiving any call at all but the signal bars are full?

I read these but it mentioned N5 only,
but I did experienced this problem couples of time in different days and it last for so long that I didn't know at all
(only found out when someone did leave me voice mail and it popup)
I am using 4.4.2 rom with hybrid modem LTE enabled,
I am trying with LTE disabled right now and see if the issue fixed.
If you dial *#*#4636#*#* it'll bring up a menu. Click phone information and make sure if you wanna use LTE make the selection to LTE/GSM auto not LTE Only. I've has that problem and i could receive calls or texts. If you wanna go back to HSPA+ use WCDMA Preferred. Hoped that helped

It could be your radio, hopefully switching to use LTE every time you want to use it isn't that much of a pain
