[Q] Help trouble LTE x9007 - Oppo Find 7 and 7a

Hello there,
I am the proud owner of an oppo find 7a x9007 (Chinese version)
great phone but unfortunately I encounter a very annoying issue.
My problem is the following::crying:
4g is functional, no worries on that side of.
but while 4g is enabled, I can not receive or give a call, if I call, it puts me out of coverage and I lose the entire network.
if I receive a call while 4g is on, the call is routed directly to my answering machine.
to be able to make a call, it is necessary to go into the settings, mobile networks and I put 2G preferred network type.
it's pretty annoying to switch each time a mode to another.
I also note that I have this problem with all kinds of rom, cyanogen, color os ... same result.
Some one has already seen this issue?
Thank you for your help.

new HTC user here having a weird problem

hey guys
ok so i have the TP2 running WM 6.5 professional
ROM 1.86.401.0 (67102) WWE
ROM date 25/9/2009
radio 4.49.25.17
protocol ver. 61.44tc.25.32U
my service provider is Etisalat in the UAE
the problem that im having is that when i set the BAND to AUTO, it picked up the the 3G network...but problem is that it keep shuffling between 3G and EDGE. because of that it wont recieve calls. one fix i was told was to manually select GSM BAND. the call problem was solved because of that.
but since i have done this, i been having another porblem. after using internet to say update the weather tab, i cant make or recieve call, or send sms or anything. everytime i use internet on the TP2, i have to switch to AIRPLANE MODE and then back to PHONE its driving me nuts
anyone facing the same problem? or has a fix to this?
Switching between 3G and Edge is normal, because not everywhere you have good service.
But just to make sure:
When you set band to AUTO and you are switching between 3G and Edge, can you call someone?
I had problems with my HTC Kaiser in the UAE. Etisalat and Du told me they only can provide mobile internet to BlackBerries and IPhones...
yeah, when it is switching between 3G and Edge, i cant make calls and i cant recieve calls either. they say my cell if off while its actually on

Go into the Bands page (where you manually select the bands). Press "WCDMA" to enable 3G only. That will keep you in 3G, but if you go into a non-3G area, you won't get any signal at all.
EDGE can only handle one thing at a time. If you don't have an active data connection, you can use the phone (call, SMS). If data connection is active, you can't use the phone functions. So, if you're on a webpage and someone calls you, their call won't go through.
3G allows you to use phone functions and data at the same time. So if you're on a web page and someone calls you, you can answer it.
ok that was surprisingly simple.. thanks
Edge can only handle one thing at a time? I routinely get and make calls and browse at the same time (or get emails via active outlook push connections, etc). And this is both when I'm in Edge areas (eg when I go to my cabin in Montana (heck - ANYWHERE west of Milwaukee) or when I have 3G (around here).
This does, however, appear to be a feature strictly of AT&T. But I don't believe the inability to do simultaneous data and call is a hardware or even Edge technology limitation - I believe its a network specific limitation.
Having said that, my money would be on an incorrect radio or DLL hanging around in the phone...
(Standard disclaimer: I know nothing about non-US carriers or their oddities. I reserve the right to be wrong- a right I exercise somewhat frequently )
well i upgraded to WM6.5 so the radio is the one that came with the upgrade.nothing else has been changed.
have a feeling the problem is with the phone as my pervious phone, sony ericsson's P990i had absolutely no porblems switching from data to call and back to data without having to do anything.
one thing i noted is that once i start an internet session, it keeps running unless i turn the switch to airplane mode to force a connection break.

Voicecalls not coming through whenever data is on

Guys
Noticed something funny with my Galaxy Nexus. Calls don't seem to be coming through whenever it is transmitting or receiving data on the 3G. I can still make calls no problem.
My previous phone (the N97) would disengage packet connection (a warning comes up) before the call comes through.
I'm still analysis the data but I am hoping that one of you has experience this before and can offer some insight.
I've done the following test:
1. Wifi and 3G on. Some calls come through, some goes to voicemail.
2. Wifi and 3G on - streaming a video from my NAS box - Some calls come through, some goes to voicemail.
3.Disengaged Wifi and 3G on - Some calls come through, some goes to voicemail.
4.Disengaged Wifi and 3G off (2G only) - Calls comes through fine (when I send text I get the volume bug).
5.Disengaged Wifi and Data on but only on 2G - Calls comes through fine.
In all above instances when the 3G/data is on, I make sure I am transmitting (I synch my hotmail account).
So is this normal (this is my first android phone)? Am I the only one or are there others?
Any feedback would be appreciated.
Thanks
***** Sorry for the question mark icon, I put [Q] down but didn't know by selecting the question mark, it overrides it************
Which network?
It's certainly not normal behaviour in Gingerbread and earlier at least (still waiting for my GN to be delivered). Even on 3G calls should be able to come through and then if needed decide to switch down to 2G if it decides it's needed.
Have you confirmed that you can actually make and receive call on 3G currently? Might be something wrong with your plan or your SIM.

I'm still testing but it does appear that whenever it's transmitting on 3G (3G or H in the icon) incoming calls go to voicemail.
I just did another test, in the previous tests I was just calling my voicemail service (901) but I decided to call my house phone and here's the strangest thing.
- With the wifi on and 3G I couldn't make any phone calls (apart from the voicemail), the calls just end. I turned off the wifi, tried making a call it works. Then turned on the wifi on again and I can make calls again. How bizarre.
I'm hoping it's a network issue but I won't know until say about a weeks time (if its a network issue it should have been fix within that period). But my first adventure with Android isn't going very well.
Rang O2 and it sounds like an issue with the network . According to them 3G was affect all over the country recently and still have issues in the London area.
I also put my sim back into my N97 and after numerous attempts was able to replicate the fault So happy.
But the customer support suggested that I should still go and get a replacement sim from the shops tomorrow since mine is quite old. From 2009 but still 3G enabled.
So fingers crossed that its def a network issue and not a fluke that it affected my N97.
How will a new SIM be able to work better? I thought, as long as it has 3G, it's all good?
My SIM is from 2008, I guess, so quite "old", as well...

Does SIM age really matter? I've been using the same SIM card since 2005.
I don't know if the age of the SIM matters, but what I do know is after I replaced my old SIM (AT&T) my data got faster (a few phones ago).
It never hurts to use a new SIM. The manufacturers change every few years (gemalto, etc) and I'd bet that newer is better...

no calls or data on ROGERS Canada

Hi all, I hope I can get help here since I'm getting crazy trying to have my p8000 with Rogers connectivity.
I've tryed on both Stock and Eragon roms with same results.
The phone seems to only be able to find 1 network - ROGERS 4G. It registers it, but then I can only get the messaging to work... both calls and internet are still down.
Also important to say that the reason why I can't see the LTE might be related to my old sim card. I'll be replacing it soon.
Anyways, in the mean time I could use some help with:
- assuming I can only connect to the 4g, should I be able to have calls at all? are calls delivered through 4g? 3g? 2g? all?
- Any reason why I can only see 4g? is the phone not capable of connecting to 2g/3g?
- anything else I could try? different modem drivers, some app to assist on this?
Thanks
update
I partially solved the issue...
few notes.... since I leave in canada, the 3g frequencies do not work...
So, I can only have internet with 2g or 4g....
no this brings one other issue regarding receiving phone calls while phone is in 4g... it does not know the calls are coming since they are transmitted using 2g... any way phone monitors 2g incoming calls while using 4g internet?
Hi
Any progress on this. I have the same issue (p8000 and rogers) Have you found a solution?
I'm on Rogers with the P8000. When it is showing 4G, I'm surfing away fine. Making a call, it switches to 2G because like most carriers (other than Wind/Mobilicity), voice calls are on the 2G network. I dont believe the P8000 has 3G bands that we use in N.America so you are only going to get 4G or 2G.
According to willmyphonework.net, the P8000 is able to use all of the frequencies. Therefore, you should have 2g, 3g and LTE.
Is this not the case?

H812 Keeps Losing Signal (Please Help)

Hello everyone, I've been lurking here all weekend as I've been trying to stabalize this phone I bought off of Kijiji. Right off the bat, when I
installed the sim I forgot to turn off the phone . Haha, I was extremely tired & only when I removed the battery (of course) did I realize what
had happened. Ever since the sim has been in, the signal has been unstable every 5-10-15 to 30 minutes (this is without running POGO). By
unstable, I mean both data & most importantly calls. I won't be able to make or receive, when I place the call during these failures it will
say dialing, connecting... and just continue until "call ended". And when I"m called, outside of LTE just say we've forwarded your call to VM. On
LTE, it will say something along the lines of this customer isn't able to receive your call at the moment.
Troubleshooting Attempts:
- Tried SIM in a different phone & it worked perfectly
- Power Cycled Several times, Factory reset it 3 times
- Set up 2 APN's (sorry can't link yet, but google them if u like they're ez to find. LG G4 VM Canada APN's)
- ^ Tried both, both unstable, but PDA gives most stability
- I've registered to all available networks under GSM/HSPA/LTE all unstable
- Connected Automatically & Manually to GSM/HSPA/LTE together & separately. All unstable
- Phone is not in Air Plane mode
Model: LGH812
Unlocked, Original Carrier: Rogers
Current Carrier: Virgin Mobile (Canada)
Android OS: Marshmallow
Kernal Version: 3.10.84
Build Number: MRA58K
Software Version: H81220x
Now, I have just recently come across a very interesting development. Using the App Network Signal Refresh Lite,
In pokemon go I've been able to transition to a signal that will stay solid for up to 5 minutes, 3 on average. It will still
lose connection, but will usually reconnect in-app in moments. I do have to minimize it & do a refresh again in NSRL
every now and then but it's a big improvement. Before hand, when I would use go, the service (calls included) would
completely rip in seconds.
So... any ideas? I'll appreciate any & all help.
I've flashed every stock rom I can for the device too, but the signal continues to drop regardless of the OS. Some error messages I' ve gotten are emergency calls only, no service & service disabled but usually it just shows that its connected to virgin but I can't make or receive calls.
Other than the cellular service, everything else with the phone works perfectly. The wifi, the camera, the gps, etc it would be a shame to have to get rid of it but the essentials first. I have to be able to make calls.
Please, anyone, any ideas? Are there any apps I can install to fix the broadband or something.
It won't remain stable no matter what I do... and no one has any solutions
tips, thoughts or ideas? Really regretting this purchase now... It's been a
month and I still cannot get a stable connection. This is ridiculous.

You may want to check out this link (https://lg-firmwares.com/lg-h812-firmwares/) for an H81220X Bell/Virgin kdz (H81220x_00_1122.kdz) and use LGUP-NEW to install it. It might help but if not, you may be facing a hardware issue ...
Solved lg g4 losing signal
I bought my lg g4 K450 and within days l noticed my phone was losing signal constantly. By the grace of God l tried this and it worked.
Go to settings---Then to Network---To more---To Mobile networks----To network operators. Select search network. All available networks will be displayed after a thorough scan. Select your network provider with a WCDMA instead of GSM and it will register it. After it done registering, restart the phone. and u are good to go. It worked for me, if it works for u give glory to God.

Cant use mobile internet whıle on call

hi there,
i am new with OnePlus, and am i really so happy from that decision.
just i need one strange question. While on phone call i cant use internet connection on my both service provider ( different gsm companies btw ). even my old M7 was able to done that. have i done something wrong on settings? or this is like that?
thnx
regards
I can't use internet while on call me neither
No issues here. But I'm using a single sim for both data and call.
Iam on OOS 8.1 beta 4 using 2 sims, same can't use 4g when on call but only sometimes I have noticed my 4g drops down to 3g while on call, there should be a solution to this, I am gonna try some 4g booster apps from play store lets see if they help, cheers everyone.
Don't think this is an issue. I don't recall I could do this ever on any phone. But if you are connected on wifi there is no trouble at all. Guessing you can't do both ?

there's an option in "developers options" "mobile data always active" , if u read the little detail underneath it it says mobile data will be on even if the WiFi is connected I presume this way both will be on, but I still don't know if mobile data disconnects at the time of making a call, but I will experiment and see what happens, cheers.
I had the same issue on my OnePlus3 a while ago. I haven't encountered it on the 5T though. I'll try to look for a solution when I get home. In school atm.
I'm using turkey Vodafone and when I'm on call i can use internet but it drops to 3g from 4g, unless you use volte its normal when it drops to 3g.
Yep definitely an issue. I'm Virgin Media and EE
Don't remember it being the case on the OP3 but could be wrong
On op3 I remember having the same issue. And note 3 and note 1 too. That's why I don't think it's an issue per say. Maybe a wrong implementation or something. Can maybe be fixed by a piece of code (magisk or xposed)?
