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.

Hi,
did anyone using Umi Super have any problems with using 4G at 800MHz? Im on giffgaff and even though Umi Super is supposed to work at 4G under 800MHz (thats what the specification states) i cant manage to make it work. I have perfect 4G coverage, 4G sim, 4G tariff, even gave my sim to a friend with S7 edge and it worked on his phone. Maybe new update will fix that? I tried with different sim from different operator (LYCA) and it works but 4G in LYCA is at 2100MHz so I didnt really check the 800. I tried everything and still nothing. Did anyone have similar problem?
I actually bought 2 phones of the same model so I decided to check if 4G worked on the other one and as I put the sim card in I just remembered something and realized same thing happened with my phone. When I put the SIM card in for the first time it DID automatically go to 4G, ok, when I looked for available networks it found O2 4G, granted BUT!!! when i got to "preferred network type" there is only 3G to pick, and THE MOMENT I PICK IT there is not possible to go back. Every network I find from that moment is only 2G or 3G. Now i reckon that a software problem right? See attachments
It is a software bug and I think I sort it out after flashing the phone. For now I sorted out the problem using Networks app by Philipp Mangalov and switching network to LTE/GSM auto
Well it seems the data part of the UMI SUPER is not so super, is it? I face a similar problem but worse. The 4G band of 800 doesn't work(despite being advertized by UMI as supported) but luckily the band of 2100 works without any issues. The problem comes when I'm out of 2100 band coverage and phone must switch to 3G - then I lose all data connectivity completely. So basically whenever I'm out of 4G 2100 coverage(which is often) I am without any connectivity! Anyone facing the same? Solution?

I only have 3G and the phone shows that I have internet, but when I try to actually use the data it just says no connection on apps.

I don't have this issue at all. My UMi Super connects perfectly to my 4g network under 800MHz without an issue here in Uganda. You can install the MTK Engineering app from the play store and check the band compatibility on ur device and you can also set the mode using the same app under android settings.
You could also try updating to the latest OTA which is 20160810 or the one before it by downloading the files from forum post here and saving them to ur phone and updating manually if you don't have the current OTA

GravityBox is a perfect solution for this problem. You can set up an icon in notification bar allowing You to toggle between 2G/3G/4G

same problem
This is indeed a software issue, one I have come accross many times - using an app to toggle between the service types is the best workaround!
There are many apps that work to resolve this, some great ones have already been mentioned.

4g Umi Super on Giff Gaff
You need Giff Gaff settings in access point name. If you try and use O2 4g it doesn't work even though Giff Gaff uses O2 network. Settings are really easy to input but MUST be Giff Gaff not O2.

All that's needed is GiffGaff settings inputing manually. Very easy to do. O2 settings that the phone recognises when a GiffGaff sim is used WILL NOT WORK. The Network is O2 but the APN settings for GiffGaff are totally different.
All you guys that think you know what you're doing obviously don't.
No need to Root or use GravityBox or any other App.

Well said. I just shake my head in despair when I see how totally clueless people try to be teachers and Internet gurus with very limited knowledge about the task at hand. These comments should come with warning stickers.
For those who want to be able to switch between 3G/4G and LTE only, use this nifty little APK that I've attached below. It will allow you to enter engineer mode without using the dial code.
Hi
This is a bug implemented in Android 7.0.
I had the same.
1 Just force in your parameters 2G/3G networks
2 wait for network authentification (no more excalamtion mark)
3 go back to 4G
Every thing will be OK to next switch off or plane mode.
Rgds,
LTE band 7 (2600) not working
I recently received my new Umi Super and updated to the last firmware V7.01_20170413, everything works fine except for the 4G. I live in an area where band 7 (2600) is available but the phone can't connect to it. Of course, my preferred network type is set to 4G/3G/2G (auto).
I read a lot about the issue on the internet but I can't find a solution.
I checked the BandMode on the phone by dialing *#*#3646633#*#*, band 7 is included and checked. However, when I tried to remove the other LTE bands and keep only band 7, I got a message explaining that the list can't be empty ("Failed. The band is changed from not null to null, it is illegal"), though the list was not completely empty because band 7 was still selected.
Also, I tried to change the radio band by dialing *#*#4636#*#*, but process com.android.phone stopped working when I pressed "select radio band", even after I cleared cache in phone and sim apps.
Can anyone tell me how to fix the problem and get connected to 4G.
BTW, Network by Philipp Mangelow is not available anymore. Switching between 3G/2G and 4G/3G/2G settings doesn't fix the issue. I tried the giffgaff settings, but the APN gets deleted as soon as I try to save it.
Thanks

You may try to force 3G and then try to force 4G
You may try to user another IMEI number from a UMI device with 2600 support (of course backup/write down the original one before just in case)
http://www.ucc.co.ug/data/imei/2
After the update to Nougat 7.x how long does it take to do a full recharge?
Do you still have fast charge feature (< 1 hour) or do you lost it like all users reported so far?
What about your GPS? Do you have a fast fix after cleaning history and is it reliable (not losing signal often?).

Is it safe to change the IMEI number? and where can I find another number for a UMI device?
GPS is working fine, it fixes pretty fast, but I'm not sure about interruption in the signal because I haven't used it enough yet
Facts:
- OnePlus 2 (European Edition, Germany)
- CM13 (13.0-20160721-NIGHTLY-oneplus2)
- Provider: Telekom (Congstar)
My OPT refused to switch to anything more then EDGE (2G) a few days ago. First I though the network was down but after a few days I checked with other phones and only mine wont switch to 3G or LTE.
When I tried to cheange the "prefered network" toggle, I switched it to 2G and now I can't switch it back to 3G or LTE. The options are still there but when I select them they instantly switch back to 2G. Even in the Advanced menu that you can enter by dialing *#*#4636#*#* I can't change it. The setting is fixed to "GSM only".
When I search for network I can only find 2G networks. In the Results are only Vodafone 2G and Congstar 2G which is my provider.
Does any one else have a similar problem and maybe a solution?
UPDATE:
I reflashed the stock image and everything worked there. Then reflashed cm13 and now I have the same error again. So it seems to be a software bug in cm13 not a hardware bug.
UPDATE 2:
I flashed the modem from stock again. Still not working. Than I disabled the modem from the service menu and enabled it again. Then it worked for a few days but then I was back to only 2G. Now the reflashing trick doesn't seem to work anymore.
I have no idea how to fix this does anyone have a clue? I can't be the only one with this problem.

You can't have 4g/lte active on both SIM cards, so solution is to put phone in flight mode, switch your primary SIM to 4g/lte which should put your secondary into 2g mode and then you're set.

What he said.
That's how I fixed it. Still wondering why this is possible with the stock firmware. At least I didn't notice the problem with stock.

because on stock it does this automatically. You can change the network type of the SIM on which data is enabled.
The other one wont even show you the option
Hi there.
Is there any way, to toggle network mode from 4G to 2G without root?
The problem is, that when im at work or at home, my 4G signal strenght is really weak, so it drains my battery too fast. When i manually switch to 2g, the signal strenght is good.
Is there any way without root to toggle network mode with tasker or other apps, while my smartphone is connected to my home or office wifi?
I tried AutoTools w/ tasker and changed the preferred_network_mode1 according to this tutorial, but it did not seem to work:
https://www.reddit.com/r/tasker/comments/6aif23/tip_change_network_type_2g_3g_without_root/
any help appreciated.

im on the international/european unbranded version.
yes, i do have that option but i would still like to use 4g, when not connected to my home/office wifi.
I hear ya, I'm on sprint which is a bit of a pain because it'll reboot phone when switched, try dialing *#*#info#*#* from dialer and you should be able to change network type from there on that model(yes I know not exactly what your looking for), but that's only thing I can think of without having to root or reboot phone each time(I don't own that model so I don't know that particular phones software)

Hello!
I have a problem with LTE in my device. When I have it in 3G mode internet works ok (but it's 3G). When i have it in LTE/3G mode first it connects to 3G, next it tries to connect to LTE but fails and it's out of reach for few seconds, and then gets back to 3G. I figured out that it isn't SIM card issue (it works with other devices). I also checked that this phone supports 4G bands in my country. Is there any way to fix it?
Check your apns you may need change or make new one.
