[LG V30 Questions & Answers] Zoki88:
I'm literally blown away what i discovered from all testings i done, i hope people will read this, without any offense to anyone, everyone who think/said in other threads and forums everywhere that is basically same if you put European H930 OS in Asian H930DS device like having stock H930DS OS are WRONG. Yes, it's true for both OS supporting same modems for carrier networks and stuffs, but it's obviously for reason made separate OS for different devices, i never imagined that would getting proper wifi speed of 450Mbps and 460 every time i tested(in settings for wifi of course showing theoretical 866 speed), after i put OS that belongs to my device originally, never going back on EU OS. When it comes to 5GHz hotspot, button is there, but when you select it instead of 2.4GHz, button for turning on and off hotspot doesn't work, it turns off same sec you toggle on, only way to make it works is by enabling OTA on same way i mentioned in first message(dialing *#546368#*930# going to Field Test -> WiFi Test -> OTA Setting etc), but when you enable it, then again happenes same thing from before, to wifi in settings showing 433 instead of 866 😂, and on speed test not anymore 450, but 250Mbps, which is still more than previously using EU OS. After enabling OTA, hotspot for 5GHz worked(details coming next), but when you restart phone, even if OTA stays enabled, hotspot button again doesn't want to toggle on with selected 5GHz, till you again dial number to just click "enable ota" , even if it's already enabled, which is weird, so every time have to click enable OTA after restarting phone in order to make 5GHz hotspot works. When i clicked to disable OTA, in settings for wifi wasn't showing anymore speed of 433, but was showing 520, 650 unlike on EU OS where even after disabling OTA was still staying those 433 as "max", but(always some but) even if it was showing those "theoretical" 520 and 650, on speed test was sometimes 250, sometimes 320 speed, not anymore those 450, so will again refurbish phone to that same OS, and don't recommending anyone to using those OTA settings, it's not worth it for 5GHz hotspot, reason i staying on that OS is because of compatibility of modem for wifi obviously, my carrier have full signal too like with EU OS. When it comes to VoLTE, i'll be able to check that when change carrier package soon.

So about 5GHz hotspot, it's not worth it, here's what i found out: when hotspot is sharing mobile provider data, then, and only then, is true 5GHz hotspot, but it gives speed around 150Mbps(all tested on laptop), i don't know if that's good or bad, as i honestly don't know what is speed of my mobile data provider. If i connect phone to 5GHz wifi to share that wifi through hotspot to laptop, even with enabled 5GHz for hotspot, then of course it's not true 5GHz hotspot as guessing that antenna is being used for wifi, so because of that, it's showed on laptop in properties that is 2.4GHz band with wifi 4 n standard, interestingly enough, in that situation lg put to hotspot gives just 1 channel, but strong one, and because of that, sharing 5GHz wifi on false 5GHz hotspot gave result of 100Mbps speed. For 2.4GHz hotspot, it's around 60Mbps no matter if sharing mobile data or wifi(no matter if wifi from 5GHz or from 2.4GHz).

Yes i'm aware all these are just numbers, i tested more times and got mostly all these same results, they still showed me big differences to see that there were definetly some wrong stuffs going on from phone and OS, so can't say that was maybe at that moment wifi itself interrupted or anything by other people here inside

Final verdict for people who can't reading all this: don't mixing OS with devices that not belongs to, in order to have way better modem wifi and carrier performance(still have to check for carrier one, but for now looks excellent), H930 and H930DS OS are NOT same when it comes to that, don't ever touch OTA settings, don't try to enable 5GHz hotspot on H930DS with OTA, not worth it at all, not much speed getting from it, H930 doesn't have 5GHz at all and don't trying to get it. Hope all this helps.
