[Q] Wifi drops when on a phone call

UK model D855 with 4.4.2 v10h.
I notice that Wifi keeps getting disconnected when on a (3G?) call. I get notifications that the wireless is not responding, I get dropped to 3g data which works ok, but also sometimes it works absolutely fine and wifi stays active.
Any ideas on a) is it just me and b) troubleshooting tips if it is?
Addendum: when not on a call I have a 5x5 wifi signal. It also happens at home and at work on different wifi networks (Asus vs Cisco enterprise).

I have the Wi-Fi drop issues on my G3 as well. But sometimes, when I turn WiFi Off, and back on again, it just forgets every network that I was ever connected to. LG Does not know how to fix this problem, and resetting the phone does not seem to help either. Maybe it'll be fixed in a software update.

Broken Wifi but working LTE?

I bought a used G3 for $180. I didn't know at the time that the wifi doesn't work. The phone is a T-Mobile (d851) and I have a ATT sim card. The LTE/broadband works though, the only thing wrong with the phone is the wifi.
I flashed the phone to completely stock with 20B. On stock, the phone still doesn't pick up wifi (Lollipop). Then I installed TWRP and flashed other roms and none of them fixed the wifi. I used BlissPop and CloudyG3 while flashing the firmware to stock repeatably. Currently, I am using EuphoriaOS, still the wifi doesn't work.
No matter what I do, the wifi doesn't work. It turns on but it doesn't detect any networks. I used Wifi Analyzer and nothing picks up. Strangely enough, when I switch the Bluetooth on and off, the wifi suddens picks up networks but it doesn't connect to them. When I was in a McDonald's, I switched the Bluetooth on and off. It picked up the wifi but then it suddenly dropped off. The trend in Wifi Analyzer shown this clearly.
I thought this was a hardware issue so I opened it up. I tested the antenna with a volt meter and it was completely functional.
I am completely out of ideas. Any directions would be greatly appreciated.
Later on, I flashed it to 10R firmware and its still broken. Its just very unstable now. I think it is a hardware issue. I placed a mobile hotspot right next to the phone. At first it detected but I couldn't connect to it. Then it said it was out of range... even though it was right next to the hotspot... That pattern was the same for other wifis.

WiFI, Bluetooth, Camera, Cell Network, Not Working after update.

I buy used phone with kitkat on it, everything is normal on this rom, then I update to lollipop using dkz, then I got error
"Current version is not available for user. Can't find matched cust for NT-Code mcc/mnc"
After that, I realize that WiFI, Bluetooth, Camera, Cell Network, no longer working, WiFI and Bluetooth just can't turned on, Camera can't be oppened or force close, cell network keep searching, I try to reflash different stock rom, and flashing modem too but no luck.
I will try to change the battery next week as someone report Wifi and bluetooth fixed after changing Battery. but I'm not sure about the other error, is someone ever experienced something like this?
same problem here it been a month and i cant find a solution for this same as you bleutooth , wifi , cell , camera

Wifi issue

Hello community,
1. I have a low wifi signal - about 10-12 dbm less then my old lg g3 or lg g5 or galaxy j7 pro - seams it is just an integrated wifi antenna issue and there is no way to fix it
2. When scanning wifi networks I have a very not stable results: even when the signal is excellent about 55-60dbm the ssid is appear and goes all the time occasionally - seams it is a wifi driver bug
Especially I see it when using WIFI analyzer.
Couple of days before I opened thread with Sony support and don't have answer.
I must have the WI-FI card working well !
Someone have the same issues?
Someone have any ideas about fixing the low wifi signal ?
Thanks,
p.s the wifi connection is stable with day by day standard usage.

hi
I CANT EVEN USE WIFI
like u said,i found my signals are very weak at the first.
i think its just a bug and didnt care about it
however 1 week later my phone suddenly cannot connect to any wifi.all the wifi spots are shown as almost no signal and it will repeat"connecting,saved"'
and i found this is a serious problem,used Xperia companion to fix that
But it didnt work and i couldnt turn on the wifi option now.
it will reboot when im trying to turn on the wifi option.
i think its likely to be a hardware issue,but my LTE worked very well without problem.
im very Confusing now
