Ever since I flashed my phone with the wicked rom .. my data has been do constantly switching between 3g and h+... I have my network type set to wcdma only and I have a strong signal but it still drops down to 3g
Before when I was on the stock rom it never did that.. I even had my network type set to wcdma preferred ..

That's completely normal. It only shows h when your data is fully active. Its a good thing. The only difference is now your phone is telling you the truth.

Yeah dude. T-Mobile does that they call their hspa+ 4G. Technically anything that is not 3g is considered 4G. The reason you are seeing this on your new rom is because the stock tmobile rom will only display you in 2G or E for edge. Or 4G for 3G and HSPA+ otherwise known as 4G. The majority of customer roms will tell you what you are currently on.

3G/4G Menu

Where is the hidden menu for the 4g preferred setting? Isn't there a hidden setting menu. My phone tried to stay on edge. My little brother has a blaze and is right next to me and his is on 4g and mine is on edge....
I still have IMEI so that isnt the issue. :good:

go to the play market and download phone info

Should it be set to gsm/cdma auto(Prl)?
It was on gsm auto (Prl).
It seems since I flashed a Rom and then did my Nan restore to stock rooted it preferred edge over 4g.
Sent from my SGH-T999

no if you want it to prefer 4g ovr edge then you have to have it set to wcdma preferred. that's tmobile's 4g! and then when it isn't available it will simply go to edge. that's definitely your best bet.

I did that now. It still was sticking on edge. I then switched it to wcdma only and it switched right to 4g. Thing is on edge it had full bars. 4g only two. I wonder if that's why it stayed on edge. Anyone know?

So I'm visiting family in Toms River NJ and I have full bars of Edge service, but no 4G service. Should I try switching network settings or what ??

try wcdma preferred. It helps stay on 4g. There may not be 4g where you are. Might want to check on that.

So I did this same thing and it's telling me I'm on 3G.
When I was on completely stock ROM out of the box, I was on "4G" all the time.
Now, every ROM I've flashed to test out which one I like, it displays 3G BUT whenever I click on a link it switches to H+. Then when that link is done loading it switches back to displaying 3G. Am I correct in assuming that it is supposed to do this?
Edit - After reading the NEXT post while I was doing my search, it seems that I was correct. :]

correct you are. while It's accessing data it goes to H+

I have my set to wcdma preferred. Keep in mind this setting might use more battery because it's constantly looking for four g signal rather than two g or three g

If I'm not mistaken, on stock it will always show 4G, even on 3G.
A lot of custom roms change this so it tells the truth. That's why you see 3G or H/H+.

Hi there, please go to bell.ca/support and search apn settings, you will probably need to add Bells LTE settings to your phone.

Are you inside a building? Bell's LTE penetration is....enough said.

Did you get LTE with stock rom? If so it could be a setting in the rom somewhere. I also have troubles with LTE when in a building (if thats the case)

I've been outside a building and still don't get lte in the kitchener Guelph area where lte is supported I also changed the settings to gsm/lte but still never see 4G on the top

Just got the confirmation yesterday that Bell have issue with their LTE network.
Go on your network setting and select WCDMA ONLY if you are able...
This is what the tech told me for my LG and since yesterday got 1 drop connection and not 10 a day!!!

I'm on Virgin Mobile Canada (Bell) and was having issues getting 4G (LTE). I believe it was posted on the CM10 thread but I reposted this as someone else was asking the same thing, but if you can't get 4G working even with the correct APN, go to your dialer and dial *#*#4636#*#*
This will take you to the phone testing menu. Tap Phone information, scroll down to the selectable list which may say CDMA or GSM/CDMA. Change that to LTE/GSM or LTE/GSM/CDMA and that should get it working again.
This worked for me on CM10, but AOKP should be close enough that this may help you out.

I'm on Att but the 9-8 build of aokp defaults to wcdma preferred on boot up..I know I live in an LTE area so what I did was *#*#4636#*#* then choose LTE only to force it into LTE coverage after that choose LTE/GSM/CDMA prl auto then or LTE should stick..for me if I chose LTE/GSM/CDMA first it would still default to wcdma...hope this helps...keep in mind you have to perform this after every reboot until its changed by task if it ever is in future builds.

Hmmm, that's interesting. On CM10, I don't need to change that on every reboot. Not even after a dirty flash. Just after a clean flash.

I had the same problem on rogers in Vancouver also running cm10 make sure you change your APN to the lte version also where it says APN type I put default. Another thing that may confuse you is that there is no lte icon on cm10 it says 4g instead

Also what might help is don't keep to many APN stored delete all except the lte and the lte tethering one. My phone was also switching to the regular APN on booting it up

Disable LTE to save battery?

I am not in an LTE market (yet), and I'm not likely to get LTE for another 3 months at least. If I switch from CDMA/LTE to CDMA in the Mobile Networks / Network mode settings, will I be saving battery?

Only one way to find out papi

I have read that you can expect minor improvements. That seems to be the consensus with Galaxy Nexus anyway.
Sent from my SPH-L900 using xda premium

Yes, not sure how much exactly, but turning off LTE will save battery.
The Sprint Zone app gives suggestions for saving battery life, and turning off LTE is one of them.

Someone said in another thread that it didnt make any difference. So, I dunno?

What about running in automatic mode?

Not positive it was related but my phone wouldn't boot after I changed it to CDMA from CDMA/LTE.

fix for disconnect from 3g network

For anyone having issues with getting disconnected from 3g network. If you find that you are continuously getting disconnected from the 3g network on Sprint, goto your network settings and change your preferred network setting from lte/cdma to CDMA only. That should keep you on the 3g network without having to continuously reboot all the time. It's not a problem with your Rom I think it's an issue with the lte network. Being that it may not be up and running in your town. Yes they are advertising it but it is not online across the entire country yet.
