[Q] WanHu ROM 2G/3G switching?

So I finally jumped in and got the WanHu ROM installed with M's v5 patch. This thing is really nice now, hopefully it will stay that way even after I reinstall some of my apps.
One thing that I've noticed is that the ability to use only 2G networks is gone. It used to be an option under Settings » Wireless controls » Mobile networks. Any chance that may be coming back?
I know some people would probably think I'm crazy to be asking that, but in my experience the batter life was pretty much double that of what I was getting on 3G, so I'd use that mode sometimes.
Thanks for all the good work on the WanHu ROM.

You can turn off the 3g at Settings >> Wireless networks >> Data Network settings & there is also a 3g widget.

Hi,
At this point you only turn data on or off. You cannot switch from 3g to 2g.
I would like to have this feature to, because the radio at my work is very poor and the battery last much longer in 2g.
Sent from my XT720 using XDA App

switch 2g , 3g, and 2g/3g
if i have to change the default network setting (3, which mean 3g/2g auto), i can from here:
1. from the dialpad dial *#*#4636#*#*
2. from the popued menu, choose Phone Information
3. from "Set preffered network type" You can choose several options including:
"GSM auto (PRL)" (this is usually default and means 3g and failback to 2g, depending on signal
"WCDMA prefered" (this mean 3g and if there is no 3g, then 2g), this settings seems to wotk, but if you exit and return to the same menu it is changed
"WCDMA only" 3g only
"GMS only" 2g only
hope that helps.
p.s. I use Battery monitor application, which has shortcut to the Phone Information menu.

Thanks for the reply. I was messing around in those menus and could not find a "GSM only" mode on my phone. I will look again, but all I remember were an "auto" mode, a "3g only" mode, and a bunch of CDMA stuff (which doesn't apply to our phones).
But I will look again and try out the battery monitor application program as that would be nicer than typing the key sequence everytime.
And just to expand my (rather small) knowledge of the android OS. The option to select only 2G under Settings » Wireless controls » Mobile networks, is that a framework thing that has to be added?

[Guide] How to increase S4 GSM signal strengt

Many of you know that the sore point of this phone is the quality of signal reception. Informing about the mode of action of the baseband, and reading the feedback from users about their various tests, always read from their words unsatisfied a search of a radio version that could improve the reception of the terminal (and thus battery life).
Since I live in a poor signal area on the Vodafone network IT (and no LTE coverage), I thought that perhaps the solution could meet elsewhere. After PimpMyRom installation , under "Device Hidden Menu > Access Hidden Menu > Telephone informations" there is a menù was set to a profile "LTE / GSM auto (PRL)".
By clicking on the drop-down menu, I selected GSM Auto (PRL), then rebooted, and i have greatly improved connectivity to the network.
Below there is a legend about the most important items. Take the test and reported your opinions.
I recommend GSM Auto (PRL) for best battery consumption allowing the automatic signal 2G/3G, preferring to 2G when the 3G signal is weak.
- 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.

It's strange because is a System related setting that can be changed without problems...maybe in your case this parameter is linked to something other. In my case all went ok only selecting other profile (i discovered that if you select "2G only" into telephone settings, this string change to GSM Only). So my suspicious is related to a linkage to some other driver that won't make you possible to change it.
We have to investigate. However my battery drain seems lowered combined with "Wifi tx power" + "iwconfig" file used for reduce Wifi signal power to 11dB. Other small things and Jelly pure ROM 4.3 will be perfect for daily drainage use

[Q] Samsung Galaxy s II i727r Skyrocket have signal problem in 4g

I buy Unlock Phone Samsung Galaxy s II i727r LTE Rogers from Canada right now iam in India my android version is 4.1.2
When i open Network Mode Its showing me
GSM/HSPA/LTE (Auto connect)
GSM/HSPA (auto connect)
GSM only
HSPA Only
1) When i select any of the above option except "GSM only" its showing me weak network signal only 2 to 3 point instead of 5 and its keep on changing frequently not stable and its shows 4G sign but internet speed is good but weak signal because 4g Won't support in india
2) when i select "GSM only" then its show full signal and its work fine but its show 'e' sign means 2g speed very slow internet speed
3) So i talk with Idea Operator they told you select WCDMA Option but that option is not available so how to bring that option in network mode
so please help me to solve this signal problem with 3g running right now weak signal with 4g
Thanks in advance

Hi
Your observation is true..I have Skyrocket,but the ATT Version,using with BSNL..
My network mode is not exactly the same...so..I have 'WCDMA Preferred'..and using it I get 4G(HSPA)..but with 1 or 2 signal bar at my home...but at some places I get good signal(4G is not avaialbale everywhere).Since I'm not a internet freak,i switched over to 'GSM Only'.in which I get at least 4bars..with good internet connectivity('Edge'!)
India is not truly a 3G place,leave alone 4G..Mind you this is the situation at 'India's so called silion valley'--Bangalore:highfive:
If the Rogers one don't have this,may be FLASH a ATT ROM---I use

Network with 3G connectivity

Hello guys, i am from India. Here, I have activated airtel 3g and i am from Maharashtra state. Here, airtel network uses IDEA network for 3g packs as they don't own the spectrum. I kept my cell in 3g mode and "automatically select network", but it stays in 2g(Same doesnt happen in my note 2, using 3g in auto mode). If i manually select IDEA from the list of networks, it goes to 3g. I want to keep it on auto, like switch to 2g when 3g is not available. Settings are same. How to make it switch to 3g automatically. Preferred mode is 3g. Any problem in my handset?
Thanks

Help 3G, 4G/LTE Not Working on Cyanogenmod 13

I am using cynogenmod 13 latest build all things working perfectly but I'm unable to change connection type to 3G or LTE if selected 2G I have to go to flight mode and then I can change the connection type to LTE only still can't change it to 3G. When it's selected LTE as default even that time also the data connection work still as 2G sign showing as E even if I select LTE never get the H/H sign on my service provider Vodafone India please help me... and sorry for my bad english.

I had a similar problem with CM 12.1, but I solved it changing the APN. My phone has 2 APN available, I just selected the one it wasn't using and I got 4G and 3G again after some minutes.
Hope it helps.

Try changing the APN as Secuential said. For Vodafone India, I think it says 'www'.
If that doesn't work, try manually changing it.
Enter *#*#4636#*#* in your dialer.
In the 'Testing' window that appears, go to Phone Information.
Scroll down to Set preferred network type: (The default is LTE/GSM auto (PRL))
Change it to WCDMA only.
It should show H sign after a while.
Good luck.
(Though, keeping WCDMA only can increase battery usage. Change it to 'WCDMA preferred' later)
