Hi All,
I would like your assistance with something. All it's going to take is a call to you network provider after a quick test with your phone.
The Problem:
Do you miss calls even if the phone has full signal and may even be in your hand? If the answer is yes and you are on any network other than Vodafone, then you are experiencing my frustration. It's due to the networks not prioritising voice calls over data calls when there is an active 2G/GPRS connection. This is not related to the handset at all it's network-side.
The Test:
1. Turn your phone to GSM mode. For my phone it's Settings > Wireless & Network > Mobile Network > Network Mode
2. Start a data connection
3. Use an app that is data intensive e.g. Google Maps
4. Use another phone to call your phone
If I am right, due to a lack of Dual Transfer Mode capability, your phone will bounce the call.
The Solution:
The only solution is for you to call your network and complain. YOU PAY FOR THE SERVICE SO THEY SHOULD PROVIDE IT.
My network is Orange and they say they are looking into it but I have no confidence in them as they say they have never experienced this. It's been the same since I had a Nokia N95 but smart phones these days are so much more data intensive so the problem is greater.
Thanks for you time.
On all the phones I've had with Voda and O2, if I'm using data and get a call, my net connection drops and I get the call.
Hi everyone, I'm running Android 2.3.4 (OpenSoju Rom) on my Nexus S,
but the issue i'm going to describe has happened to me on other Roms and
even on my old Nexus One.
When the phone is idle, 3G data works great (also when using apps that
require an internet connection), but when I receive a call,
after a minute or two, the 3G icon disappears from the notification
bar and the phone data connectivity is lost - no connection to the internet.
I've asked around and someone told me it is because the phone switches to
2G network during the call and when in the phone is in 2G mode, during a call
there is no data (on a 2G network).
I know that in the past this behavior did not occur, and in my country
when in 3G during a call - data is enabled!
So does anyone know how to fix/change the setting that causes this behavior?
'cause, for me, sometimes I really need the data connection during a call,
for example, when navigating using Waze (which needs data connectivity),
and receiving a call it causes Waze to stop working and I lose my GPS direction.
Thanks.
Use to work for me too. Then i noticed when AT&T started saying the had talk and web at same time, mysteriously it started doing what is happening to you. And i have Sprint, unless you switch to at&t you might be waiting for awhile.

Does the idol automatically use wifi when it's available for data? I just got a sim card and activated using BYO Wireless (T-Mobile).
My old Tracfone phone had an option where you could turn off cell data and use wifi only.
Yes and no..the priority is wifi but the cell radio is still used to receive sms's and other cell phone specific notifications...when you make a call while on wifi it's still using the cell radio not wifi for the call. You however have to have wifi on and the hotspot "saved"...if you want the phone to automatically grab any available hotspot when in an area look for an app like "wefi".
Some people make things so complicated.
The simple and best answer is yes, Wifi always takes priority over mobile data if the phone is connected to a wifi signal. This is standard on all phones as far as I know.
I realize it uses cell signal for messages and calls but will it use WiFi for surfing the web and email?
Thanks shodan. I posted before your reply..
Hi Guys,
I am here with a..I hope possible to solve situation.
I have switched to our local carrier, which provides only 2G and 4G connection, but... I have 1GB of data for 4G, but my OPO is sometimes switching to EDGE, which makes me fury, because I am paying for anything transferred through 2G (separately as it is not in the data package I have), but all calls are on 2G, which makes restricting the connection to "LTE-only" impossible, becuase it would result in no access to the calls/text messages.
I have found this article
http://editorsean.com/articles/how-to-force-three-to-use-3g-and-4g-only/
which is really great, but with those options I am forced to use GSM/LTE and such..
Is there any chance of letting my calls and text messages just using 2G network as usuall, but forcing my internet access using just LTE ? There is of course an option for disabling "national roaming" (I hope, it is called the same in english), I have it disabled, but it is still connecting to the 2G and draining data from it...
Is there a chance it is a problem from my side ? I did not factory reseted the phone since buying, doing just OTA upgrades and such, so I was thinking, if the system is not kind of bloated...I had some weird things happening with it too in the past - recently I have seen that in the battery saving mode I could see some like various screen brightness jumps while playing a game for example.
Hello XDA Community!
When my new phone (Huawei P9 Lite Mini) is on 3G/2G auto network mode, it consumes more battery than LTE/3G/2G auto mode even mobile data off.
I do not understand how this happens? For example, while 3G consumption at overnight is %10-15; LTE is only %2-3. This problem is the same in daytime too. Mobile data is off, unneccesary services/apps disabled, and no extra application installed while this happens. I tried all "wipe/factory reset/update firmware/factory reset/wipe/no app install" procedures, enabling all battery saving options, but it did not work. This is a problem for me when I'm in non-LTE areas.
This problem occurs the same result in different locations. There was no problem with my previous phone and I use same nano sim card.
I tried the following but it did not work:
- Wipe cache, factory reset, wipe cache,
- Wipe data/factory reset over recovery menu,
- Update latest firmware, wipe data etc. again.
How this happens and where am I doing wrong? Thank you for your help, best regards!
EDIT: PROBLEM SOLVED!
I changed my mobile carrier (provider) and the problem is gone. This is very interesting! I worked for hours and days to solve the problem, but this problem is neither caused by the phone nor by the software...
WCDMA (aka 3G with support for 2G/Edge) is in always-on mode on most phones, because that's how you receive and emit phone calls and, for most phones, SMS (in some more recent phones, LTE takes care of sending and receiving SMS/MMS), so if you're in an area where 3G/2G reception is poor, your phone has trouble locking on a cell with enough power to maintain contact, hence the battery drain.
4G/LTE only works for data, and voice if you have VoLTE (Voice over LTE) enabled, but works on a on-demand mode, even with cellular data constantly enabled. In other words, the 4G modem on your phone will memorize the latest position and IP address the nearest 4G tower/cell allocated it, and connect to it using the memorized settings when you need it to.
Not so with 3G, where DHCP doesn't exist, at least not the way it does in 4G: it uses PPP (Point-to-Point Protocol), where an ad-hoc IP address is attributed to each new connection, based on a pool of existing addresses allocated to the tower and its owner (carrier) by the authorities.

Thank you for your reply!
When I googled about 3G vs. LTE battery consumption, everyone says that LTE will consume more batteries. That's make sense on first thought. So what I've been through is very interesting to me.
I think about is there a problem with my phone's 3G antenna. (footnote: I don't know about that 3g and LTE antennas are same or seperate?)
But I understand that you say this is normal, right?
Edit: I found a forum that this problem may be due to the operator (carrier). I'm still investigating...
3G and 4G operate on basically the same principle: receiving and sending "information" via radio waves.
The difference lies in the frequencies each standard uses, the way the data sent over them is modulated and demodulated, and how handsets make and maintain connection, so if you stay in the same location, and set your phone to 3G-only, then switch Airplane mode on then off, it'll take your phone longer to reconnect to the 3G cell/tower with the strongest signal (not necessarily the closest to you), because it'll have to go through the whole getting-acquainted process again, whereas in 4G, it'll go straight to the "Hey, how do you do? Long time, no see".
Now, if your phone antenna has a problem, you could be standing a few feet from the tower, in line of sight, and still get a crappy to non-existent signal. How many bars are showing on your screen is just an indication of how well your phone is receiving the signal from the tower; it doesn't mean that this signal is consistent and steady, hence the bars coming and going in real time.
If I were you, I'd download and install the Hidden Settings app from the Play Store, and run it; there, you go to RadioInfo, and you'll get a lot of information about how your phone modem actually works. It's a bit technical, but it would give you an indication.
I will try and looking for a new carrier. Thank you again. See you.
