My data turns off while in a call - Huawei Mate 9 Questions & Answers

Using stock m9. Data 4g or other turns itself off when I start dialing and reconnects after I complete my call. Very frustrating when I need to search something while talking. Is there a setting I'm missing? Has anyone else noticed this?

Probably, you are missing VoLTE. Without this technology when phone using 4g and receiving call, it jumps to wcdma (3G) to get call, but drops mobile Internet in this moment.
To get everything working need:
- Mobile operator, who supports VoLTE
- Phone. Mate 9 supports VoLTE on paper, but not in all roms and not in all regions. For example, owner is living in USA, but has Mate 9 with chinese Rom -> no VoLTE.

You will have to enable VoLTE in order to get rid of the trouble.

I have the same issue also. I own the dual SIM variant and use one card for calling and the other one for mobile internet. Whenever I start a call the mobile data connection is stopping. I tried to enable VoLTE with no success.

In the latest C432 roms Huawei has removed the possibility to enable VOLTE for Vodafone Italy.
This possibility was present only in the first 2 update.

This is other case. If you are using one card for calling only, and second card for mobile internet only - you can't get call and mobile data together, cause Mate 9/Mate 9 Pro are DSDS phones (dual SIM dual standby)
To get what you want need have DSDA phone (dual SIM dual active). They are with two independent radio modules. Honor 8 for example.
Dsds phone has only one radio module but uses interchange method of work. On physical level it jumps from first sim to second then gets back to first. If you are in call with first sim, phone does not go to second -> no internet.

How's the audio processor?
For recording videos it is very clear and loud. Haven't tested it with a hifi earbud yet. Sound from speakers are decently loud but do now sound as bassy as the HTC one or nexus 6 speakers. One thing that's great is there is NO stutter when listening to audio with the front facing speakers and changing from landscape to portrait (as happens on the nexus 6)!
How does NFC work?
NFC is the same, tap on something and bam, nfc'd.
What are uses for the fingerprint sensor besides unlocking the device?
So far under android 5.1.1. Just to unlock the device. Once marshmallow comes out I'm sure more uses for it will follow.
How's the video quality?
Video quality is amazing. Colours have a nice balance to them. I turn off the x-reality engine.
Does it overheat or start to get warm during tasks?
Warm when charging and doing some serious downloading or installing a **** ton of stuff. Not hot at all. Haven't recorded 4k video. Will wait for the new camera app to be pushed out before I make any judgments.
What's your best SOT?
So far after one day of use 3.5houra SOT at 75% brightness constantly.
How easy is it to switch networks with two sims?
Seems fast enough. Just pick which for LTE and which for gsm voice. One thing of note... you cannot use LTE simultaneously on the z5 Dual. You can have one as LTE and one as gsm (2g) for voice and text only (so basically Rogers). Calling when one on sim and if someone calls you on the other sim, it will forward to your voicemail.

When you say "just pick which for LTE and which for voice", do you mean you can actively pick which SIM is using LTE Data via the settings app, or do you have to physically switch out the SIM cards in the actual device itself? I currently have a Dual SIM Phone but to pick which one gets Data, I have to physically remove and switch the SIM cards, not through the system's settings.
You can switch them actively on the go via the settings. Sucks you can't use LTE for both sims at the same time though, but I guess that would be a huge battery drain
got the single sim - E6653 on Rogers in Vancouver, so fast!!!
I have a follow up question on the dual sim support. So you mentioned one SIM supports LTE and one will support GSM/2G.
So is the second SIM is only 2G or can you get 3G/HSPA support?
Also what happens if you get a call on the LTE SIM? Will the phone CSFB to 3G on the LTE SIM's network to accept the call (since no VoLTE support)?
Hope that makes sense.
I was considering the dual sim model since I have two SIM's myself. One for work and one for personal. Both are voice and data LTE but on separate networks (AT&T and TMobile). If i'm hearing you right then there isn't much advantage for dual sim in N. America since 2G voice isn't any cheaper than the 3G or LTE...in fact the 2G networks kinda suck now since all the focus is on LTE and getting to VoLTE.

As far as I am aware, it supports gsm network (most likely 2G only). I don't have data on my 2ND sim so I'm not sure if it supports 3G data, I doubt it though.
If I receive a call on the LTE sim, it reverts to hspda yes. No VoLTE on telus AFAIK.
Hello,
I also have Z5 Dual on my hand, and I have bought a QC 2.0 supported charger from the shop, and I tried to charge my phone with it, but I don't know if I can check whether I'm using quick charging mode or not, do you have any idea?
Thank you!

Just time it. Quick charge is usually 0-100% in about 1.5 hours. Which charger did you get?
Hi Guys, really want to find out if this phone supports dual 3G standby. They are turning off the 2G network shortly in my area and need to know if it will work.

Does the Sony or Android UI tell you which network you are connected to on the primary line? In screen shots it seems like it just shows signal strength on both lines. I'm curious if it says LTE, 4G, H+ or H. My ATT service switches quite a bit here in Houston so sometimes I force the phones to 3G only in areas where reception is awful.

Hi there,
Could you please post a screenshot of the service menu of your Xperia Z5 Dual? I'm interested to see what are the working bands of this phone listed in this place.
Enter *#*#7378423#*#* in the phone dialer to open up the menu.
Choose "Service Info" and then "Configuration".
Capture the screenshot (feel free to cover your IMEI there).
Thanks a lot!

My Xperia Z5 Dual will got the following message and forced to restart when I have changed "Preferred network type" in settings--->More--->Mobile networks--->SIM1/SIM2, or even I have replaced another SIM card. (I have turned my phone off when replacing SIM card.)
Your device will now restart to be optimised for your service provider.
This is very annoying and anyone knows how to fix this issue?
Much appreciated!

I stand corrected, its 2G standby! That being said you can switch the primary data line to SIM2 to LTE/HSPA which forces SIM1 to 2G :crying::crying::crying:

Nougat modem issue "No services, emergency Calls Only"

I m using my G930FD (Dual SIM) phone from may 2016. On marshmallow i didn t have any problem. After I switched to nougat, problems occurred with reception on 4G.
Where I live, the phone uses the Band 20 (800Mhz) and working both Sim cards without any issue, everything OK.
At my workplace LTE uses Band 3 (1800Mhz) appear the problems. After a random period of time, SIM1 unusable switch off from network and get "No service, emergency call only". Airplane switch ON/OFF, and SIM 1 functional again.
You can see the actually used channel dialing *#0011#
I think the problem is related to nougat modem, and only on BAND 3. Tried 4-5 different nougat modems, but no lucky.
TEMPORARY SOLUTION: flashed back marshmallow 6.0.1 modem G930FXXU1BPL6 and now seems ok.
Anyone else have this problem?

I'm not using the dual SIM version but the normal one (G930F). I also have some issues with 4G data dropping to EDGE/GPRS after a call and occasional "Emergency calls only" message. This would either require a restart or a switch in Mobile data type (LTE/3G/2G) and revert back for it to be fixed. I've also tried flashing different modems like you've done. I initally had the NEE region in Marshmallow (which I remember had the same issue, but less frequent) and then I updated to Nougat by flashing the BTU firmware.
I will try the modem that you have mentioned, hope it all gets fixed after that Thanks :good:

LTE 4G not working on both sim

I'm on 5.1.9 but despite i activated the option only the Sim used for data traffic can actually connect to 4G. The other Sim seems forced and stuck in 3G at 900MHz (band 8)
There's no use for LTE on the phone sim unless you are lucky to live in China, India or Finland AND use a sim card of the view carriers supporting VoLTE in the OP6.
No sense reply. OP declares dual 4G on both Sim. My phone supports 4g only one sim and the worse the secondary sim is locked on 3G band 8
Are you using any custom rom? i faced similar issue on havoc rom

No. Pure stock 5.1.9
I had the same problem. But i went back to 5.1.8 and problem solved now dual 4g active.
Crazy but settings the phone on the English instead of my local language the problem seems gone.
I'm in America and I'm having the same problems after the 5.1.9 update, one SIM is always in regular GSM mode even with the dual-4G mode enabled.

That is completely false. Even T-Mobile in the US supports VoLTE. Even if it didn't though, it still allows for faster SIM switching since it was already on LTE.
Curious how you guys are checking it. Mine both say VoLTE and it seems to be fine for me.
I reset the network settings and it work for a few hours. The dual sim 4g instructions are broken .

Help me - Infocus m808 is working only in 2G

Hi
Maybe you can help me.
I used my M808 2 years. In 2 days i can't call and sms and don't have internet when i have 3G or 4G. When i force 2G i can call and sms. In 3G i can see range but i cant call to anybody.
Do you have idea how i can fix it?
I done hard reset and nothing, I try my SIM card in other smartphone and there i had 4G ok.
Will Change rom help?

This could be caused by a few things.
1. Hardware fault.
2. Your carrier (SIM Provider) switched to a none supported band or bands. The M808 does not support LTE band 20 (800mhz) which is common in Europe
Supported Network Bands:
(2G) GSM 850/900/1800/1900MHz
(3G) WCDMA 850/900/1900/2100MHz
(4G) FDD-LTE B1/B3/B7/B8/B28
3. APN settings although this would not affect voice calls
4. Your carrier Decided to block your phone by IMEI from using anything other than 2G and yes they do sometimes do this O2 did it to me some years ago now with absolutely no warning or reason given so I will never ever use them again the arrogant s****
5. Duplicate IMEI someone is using a phone with the same IMEI as yours on the same network. This can cause all kinds of strange stuff to happen. Again happened to me when I restored the incorrect backup. Both mine and my sons phone ended up with the same IMEI . It took ages to work out what was going on with that one
I would suggest you first try another sim card from another provider that use's the supported bands for 4G (3UK) if in the UK it used to work fine on my Old M808.
I done some tests.
I put my sim card to other phone - everything is ok.
I put other provider sim card to my phone - only 2G is working properly.
I done flashing - no improvement.
Im afraid hardware fault.
Any more sugestions?

HD Audio/ VoLTE

Is there a setting to enable VoLTE or some sort of HD phone call audio? I searched everywhere and i can't find something... The top speaker sounds like the other person is on speaker and talking from the bathroom...
Yes it's in the "Network and Internet" settings, under the "Mobile network" category.
Sorry if the labels are different on your phone. I'm using it in French.

It probably depends on the SIM card.
You could try asking your mobile network provider for a new SIM card. But I'm not sure at all that would fix this.

My network operator is Orange/Sosh(France) and there is no option for the VoLTE.
Guys the truth is... The phone is compatible with only a limited set of band frequencies..
THIS MEANS
Volte, 4G 5G etc will ONLY WORK IF your cell phone provider has the same frequencies that the phone requires.
If you cant enable Volte, It wont work cause your phone is NOT capable of working on your Cell Providers cell tower freqncies. Each company uses a different Frequency
Here in USA
ATT will ONLY work upto 3g. You will see an H on top the signal bar which indicates a Enhanced 3g speed also know as HSPA speed connection. I have tried 2 new sim cards. I have tried several APN's I have tried all updates and a reset. No 4G and no 5G on ATT. Unless someone can tell me something new, this phone will not FULLY work on ATT. Text works. Calls work. Internet is sort of hit and miss with decent signal but again rather slow.
T Mobile will ONLY work upto 4g. No Volte although it seems to have the capability of Volte it cant not work with Tmobile Volte because it seems the cell bands are not compatible. Text work. Internet works rather fast, Good solid signal however no 5G and no Volte due to incompatible cell bands.
I did research on this subject and found that the ATT cell bands for everything including 5G do seem to be compatible with the 7 pro but again, it does not FULLY work oddly
I also did research on Tmobile cell bands and the bands for 5G are not even close to being compatible. Volte is also non compatible. 4g is compatible and works..
If someone has a magick wand which can somehow make these features work on this fone in USA Id be willing to send a donation..
