[Q] GSM D802 - no SVLTE?! - G2 Q&A, Help & Troubleshooting

Hello,
I own a D802 for a few days now and I just have performed a LTE test - I switch the phone to auto 2G/3G/LTE, the phone is indicating 4G, I performed several SPEEDTEST.net and everything appears to be fine...excect that I cannot receive any calls...all incoming calls are forwarded to voice mail.
When I make a call the phone switch to 3G , that seems to be normal, but it doesn't go back to 4G as it should...in theory that's the flow (CSFB)
Has anyone encountered the same issue? This is how the D802 is working? Is it a phone issue?...or is it the provider?

[Q] Cant make and receive call when roaming on gsm

hey all
i've got a problem with my droid pro in eu on gsm/umts network.
when i'm roaming and use gsm only (no umts) my mic and speaker are dead. i can make a call and receive it, but i cant hear anything and caller doesnt hear me. display shows seconds have past so line is opened. i can even receive sms and mms just fine and send them, only cals dont work.
if i change from gsm to umts only, then calls work fine. when im on home network everything is ok.
funny thing is, that if i make a call on roaming in umts only and then change to gsm only i can receive first call, then it's all blank again.
i have stock rom
tnx
teva
probably the problem was with the network where you was located. did you tried another network?
my droid pro works nice in roaming, in both gsm and umts.
I am facing a similar issue.
2G 900/1800 Mhz -- Voice & Data Work fine.
3G 1900 Mhz --- No Voice, Phone re-boots. Data works.
So I have to use the phone in GSM only mode.
I am on 2.3.3 / Verizon 4.6.4 update.
My new operator have same issue! (no with the old operator!!)
In a specific location i can't make/receive a call in only 2g (i can send/receive sms and data traffic is ok)... But if I switch in 3g i can do everything...
For my operator it is an issue between sim (by ORGA) and droid pro and so I'll replace my sim...
I didn't find non ORGA sim, but i have bought a dualsim adaptor, for seeing... Nothing...!
On my operator (TIM), when i'm on edge in only same locations, i can't make/recivie calls... Not with my ex operator (wind)..
But... you can try to compose on your dialer ##7764726 then call, then password 000000
verify
06 test mode
next
next
service option switch to 13k, or others, then back...
Make a call, or try this configuration
if you restart your phone you must reselect this...
Tomorrow i'll try...

4G Problems with D802 (3 UK)

Had a Nexus5 that performed flawlessly on 4G, but wanted/needed the extra battery of the G2.
Bought an unlocked new D820 G2 from Ebay UK. Phone is great except for 4G.
Firstly, it defaults to GSM/WCDMA. I can change it to GSM/WCDMA/LTE auto, but every reboot will reset it to GSM/WCDMA only.
Secondly, when connected to 4G, any incoming call goes direct to voicemail.
Thirdly, when on 4G and making a call, it first drops to H/3G, then loses all mobile internet, and when the call starts to dial out, reconnects to H/3G (but never 4G). Afaik, the D802 G2 should support SVLTE?
I can get into the service menu, but when clicking LTE-Only I get "not supported".
Any ideas what the hell is going on?
The software version, baseband version and firmware version all check out as being UK/up to date - and the phone hasn't been rooted or tinkered with. The SIM is the same 4G SIM that worked fine on the N5
Any reply on this issue?

Note 4 (SM-N910F) dropping calls and can't receive calls when 4G enabled

Hi All,
I have a Galaxy Note 4 SM-N910F with BTU firmware N910FXXU1ANK4 (UK) which I flashed from the older O2 UK firmware N910FXXU1ANJ4 when I bought it.
I am having problems receiving calls and making calls when 4G LTE is enabled on the phone (I get 4G signal bar). When someone calls me my phone rings and the signal bar is 3-5 bars usually and when I slide to answer the phone it seems to answer (timer starts clocking up) and I can't hear anything (sometimes for a split second) and the other person can't hear me, then the person is directly kicked to my voice mail!
If I try to make outgoing calls with 4G enabled it sometimes works but other times it sits there saying "dialling..." then after 10 second or so gives up and stops. If I do manage to call out I get terrible phone recetion breaking up and high pitched noises sometimes. Sometimes it is ok for a while talking but eventually the call drops at some stage.
If I force my phone into 2G only or 2G/3G only then the phone seems to work completely normally.
I have had multiple SIM swaps with no luck.
Samsung walk in repair centre was useless as the empolyees all appeared to be undertrained kids.
O2 was no use saying there is no transmitter faults reported in my area.
Before I try a hard reset and flashing back to the old O2 firmware and then possibly sending my phone away for repair, is there anything else that might be going on here? Has anyone else seen this or know if it is a known problem?
Cheers,
Richard.

Most mobile providers still don't support VoLTE (don't know if that is the case in UK) so your phone needs to go down to 3g/2g when phone call is received.. So maybe there is some problem between BTU and O2 firmware (I am no expert, but may be CSC related)..
I suppose your network selection on 4g/3g/2g automatic mode, not LTE (4G only)?

I only have the option of :
LTE/WCDMA/GSM (auto connect) - Have the issues with this mode
WCDMA/GSM (auto connect) - No issues in this mode
WCDMA only - not tested
GSM only - No issues in this mode.
In phone dialer hit settings. There should be a volte toggle if there is turn it off.
I don't have any issue like that. 4G turns to 3G or 2G when receiving/taking a call. May be u hav an issue with ur firmware
I've tried flashing back from the BTU UK firmware back to the original O2 UK firmware and the problem remains. I also tried a hard reset afterwards leaving the same issue.
I have noticed that the issue does occur with 3G as well as 4G but it seems to be a bit more stable. 2G seems the most stable.
I have arranged with Samsung to send my Note 4 for repair so hopefully that will resolve the issues.
I have the same problem using 4G. Sent for replacement. Waiting for feedback..
got information that warranty service did find the problem and in a week or so I will get new one
I HAVE THE SAME PROBLEM!!!! THANKS A LOT !!!!! I WAS LIKE CRAZY TRYING WHAT CAN BE WRONG WITH THIS....
In my situation i can
send and receive sms on all mods
I can call in 4g but i can't receive calls when im on 4g... - just only hire is a issue
Last time my charger when i was charging in night get burn and i think meybe form that time... i have phone 3 weeks brand new.

Leon LTE (MS345) Problem: "Searching..." forever but SIM is OK

Just posting this in case somebody has some ideas. I've had a MetroPCS LG Leon LTE (MS345) for over a year without problems, but now it started losing its mobile connection sporadically, for a few minutes or a few hours, as if there was no SIM in the phone.
Symptoms:
The 4G indicator disappears from the notification bar (signal strength indicator shows good signal).
The lock screen says "Searchng..."
Calls fail with the "Emergency Calls Only" message
SMS won't send
I get a "Service Unavailable" error when I choose Settings/Call/Additional Settings
WiFi is unaffected (and WiFi calling seems to work, though it has always been hit or miss)
Things I've already tried:
Checked relevant settings, APNs, etc
Checked the contacts on the SIM socket, all looks good.
Reset Phone to factory defaults
Replaced SIM (MetroPCS did this for free)
New phones are relatively cheap, but I don't have a burning desire to upgrade, so I'm hoping for another option.
I'm having this same problem. I left for an area with no service and came back to an area with service to find that my phone will constantly state Emergency Calls Only and no service. Does anyone have any suggestions?

Incoming/ Outgoing call problem while on 4G network with no volte support.

I have recently bought the MI A1. While buying itself it was updated to the latest may patch.
The problem is while on 4g network, I cannot receive nor make any phone calls. For calling I have to manually switch to 3g/2g mode from *#*#4636#*#* menu. Is this a normal behavior of this phone as my other phone swiches to 3g while incoming/ outgoing calls and back switches to 4g after the call is finished.
PS: my network doesn't support volte. Phone is manufactured on Feb 2018, it's not modified by any means.
That's not normal behavior.
I've never seen a phone where You have to switch between 3G/4G/LTE for calls and data.
Can You try a SIM-card from another service provider to see if it behaves differently?
If You check at https://willmyphonework.net/ are all bands supported with Your provider?
Or, in worst case of course, try a factory reset and see if that makes any difference...
Set to 3g/4g in *#*#4636#*#* menu.
Airtel doesn't support volte in all circles yet. Only rolled in few circles. In 3g/4g mode, it'll be mostly in 4g mode if nw strength is good & switch to 3g when you call or receive a call
