I recently bought the S4 Mini i9190 (standard 3G model) I was well aware of the different variants when i purchased. The seller was offering all 3.
Phone was purchased unlocked / new.
I have a 20 mbps internet connection at home and an apple AP extreme router. We have no problems with our devices. There are other smartphones here such as iPhone and Blackberry without issue. Wifi keeps dropping off drastically or cutting out and coming back on the i9190. I am really disappointed. Interestingly enough I had the same issue with a GS3 that I tried for a few days back in April before returning to the store.
I did not have those Wifi issues with a Moto XT926 or the iPhone 5c. Regular iPhone 5 gave me WiFi fits and there is a thread on Apples official forums with 1 million views detailing that issue which was very phone specific.
The seller is willing to give me a refund outright or exchange for one of the other models 9192 or 9195 OR perhaps S4 Active (with some added $$ of course). I'm wondering what I should do.
There is a youtube video about S4 and wifi problems, and changing the encryption cypher from TKIP to AES. I don't know if this is possible on my router. I am just really disappointed. Otherwise its a great phone. With only 1 GB of data per month, i want to use WiFi as much as possible
Thanks.
I see some people saying they already turned on their VoLTE, how does one go about doing this? I'm on the latest Kernel, running the latest PacMan ROM.

It's in call settings. Isn't pacman AOSP? it might be limited to TouchWiz roms.

you need to return to stock in order to get the volte. when you try to restore via KIES it will ask you if you want to upgrade to the ne6 baseband. click on yes and be patient
So we can't use custom roms to get volte? We have to stick to stock rom?

Volte will not and does not work at all if you are using Pacman rom
or any other AOSP, AOKP, CM or ported roms.
You will need to flash a Samsung N900T Kitkat 4.4.2 Touchwiz stock or
stock based custom rom if you want to get the Volte feature working.
Good luck.
yea i tried flashing all the different options/roms trying to figure it out. only the stock telco rom works for volte. thanks
XtreStoLite custom rom

I have been searching for custom ROMs that can do VoLITE and i think I found one called XtreStoLite but I do not think it will work yet on your device. Someone told me something about wrong kernals, and until they make it install from a universal zip it is not workable yet.
But I would keep an eye out on that one and I think they are going to soon come up with more custom roms with volte.

T-Mobile Unofficially Speaks To Us About Band 12 LTE / VoLTE And Unlocked Smartphones,
And Yep It's Still Confusing
-----------------------------------
Yesterday, we published an article asking an open question: what is up with T-Mobile band 12 support being removed from some unlocked smartphones?
Today, T-Mobile contacted us to speak about said article. Unfortunately, T-Mobile was unwilling to provide any official on-record responses to our questions. But after a short discussion, I can provide you some information I have learned on background (journalist speak for "cannot be directly quoted or attributed to anyone"). First:
On T-Mobile, any device on its network with band 12 LTE data support must also support T-Mobile Voice over LTE services and E911.
The E911 part isn't particularly important in terms of the certification requirement - all phones sold in America are technically E911 compliant, because by law they have to be. The problem is that E911 compliance is inextricably linked to T-Mobile's VoLTE requirement for band 12. Without VoLTE support, a device on band 12 service would be unable to make phone calls of any kind if no other T-Mobile band was available (it will not know to fall back to AT&T roaming - the call will just flat-out fail), and that would include making 911 calls, meaning the device would for legal purposes likely be out of E911 compliance, and T-Mobile could get in trouble with the FCC. Not to mention, you could have somebody trying and failing to dial 911 in an emergency, which would of course be terrible. And yes, by removing band 12 support, you can make E911 work, because the phone then has no signal at all and knows to try to roam onto another compatible network (AT&T usually) to complete the call. This is both a safety and liability issue, and it is easy to understand where T-Mobile would be coming from in terms of concern about this - they do have something of a history with E911 debacles. Clearly this is a very real safety concern, and I do sympathize with T-Mobile in the sense that they obviously can't just sit here and do nothing about it. But there are practical concerns for OEMs here - adding T-Mobile VoLTE isn't just as easy as flipping a switch.
In order to obtain VoLTE compliance for band 12, phones must go through T-Mobile's rigorous network certification process (and yes, unlocked phones can go through this certification).
Speaking off the record to one major smartphone vendor, we have learned that there are very real costs and complexities associated with obtaining that certification, and it must be done on a device-by-device basis. Many phone OEMs, then, may simply choose to remove band 12 support from their unlocked smartphones sold in America. This could mean phones like the Alcatel OneTouch Idol 3 (4.7 and 5.5), the Huawei Ascend P8 Lite, the Huawei SnapTo, OnePlus 2, Moto X Style (aka Moto X 2015 PE), Moto X Play, HTC One M9 Unlocked and Developer Edition, Saygus V2, and various imported phones (ie, some global unlocked Sony or Samsung devices) or unlocked branded AT&T phone models may lose band 12 support in future software updates. The fact is, we don't know what will happen, or to which phones, or when. Some manufacturers may choose to get T-Mobile VoLTE certification (Motorola has hinted as much with the new Moto X 2015 PE), but many may also simply choose to quietly disable band 12 for T-Mobile in software updates. Motorola, as we know, has already done this with the Moto E.
It is not clear what action, if any, T-Mobile will take if a smartphone vendor refuses to remove band 12 data support from their device and also refuses to undergo the T-Mobile VoLTE certification process. (Ie, they want to keep B12 data but not bother with B12 VoLTE certification.)
This is basically the kicker. What will T-Mobile do if a vendor says "no way" to dropping band 12 data, but also doesn't want to go through the VoLTE certification process? We don't know. They might not do anything. But they might do something. Again, this is why speaking to T-Mobile about this situation was so frustrating. Not only we were unable to directly quote or attribute any of the information we were provided, but there was also no clarity as to what would happen in the event the band 12 situation comes to a head with an OEM that refuses to "play ball."
It seems unlikely that any OEM would refuse T-Mobile's request here, though, as most of them are also partnered with the company on T-Mobile-branded devices.
We have asked T-Mobile again for an on-record statement about this entire situation, because it would help clarify it immensely. As things stand now, T-Mobile is attempting to put the ball in the court of manufacturers. Which, to be fair, manufacturers do have a role to play here - they have to make the decision to drop band 12 or go through the T-Mobile certs for these unlocked band 12 devices. Or, potentially, just ignore T-Mobile's band 12 requirements entirely and see what happens. Unfortunately, as you might guess, most smartphone OEMs have zero desire to discuss upcoming software updates in detail, or to ever put their product in a situation where it is being highlighted for losing a feature. That makes our job here a difficult one.
We will update you on any more information we receive about this situation, including any response from T-Mobile or potentially-affected device manufacturers we have reached out to.

Anyone using this device on Three UK?
Does it work ok? Do volte and Wi-fi calling work?

Have used all my OnePlus devices including my current 5T on the 3 network.
In south West Wales I have 4G connection speeds in excess 50Mb/s inside and outside in urban and in Cities and my job as a mobile engineer its the same around the Midlands and the South of the UK.
I use whats app for video call not Volte.
Having sampled all the networks (O2 presently on my fruit based work device) they are all relatively the same - good areas and bad areas.
Hope this helps.
VOLTE does not work due to their stupid ass policy of only enabling it for phones you buy from them. However WiFi calling does work if you use the Magisk module VoEnabler to enable it in the settings.
I always like 3 in general, coverage in my are is quite good Hampshire ... but I get no coverage at home which is why I ask about Wi-fi calling. So would need to contact three to get a signal box.
I’m on EE currently my contract end in a month, but they just don’t seem competitive as far as price goes
So the tossup between three and Voda

I used to use one of their home signal boxes, and it was not the best experience as the phone would often fail to switch over to the device when it was in range. I'm not sure they offer it anymore as they released the 3inTouch app, which provides WiFi calling. However, you have to have their app running all the time, and when I tested it, it was fairly heavy on battery, and not a great interface (eg not native wifi calling, so you have to use their app to send texts and make calls).
Hmm
So my choice really maybe Voda or go back to my the iPhone X on 3. Or pay the extra and stay with EE
Thank you
I've access to a stock op5t and it's just updated to the official ota ores and a new vo-wifi logo had appeared in the status bar.
There's no option in the dialer to enable or disable WiFi calling, but it definitely functions. I'm not in a location to verify if volte has also appeared.

I have a friend who lives in Leeds with the same phone as myself a xioami mi6 on 3 and volte is working no problem for him on a custom rom. I am a few hundred miles south in Bedford with the exact same phone and identical rom and setup but volte will not work at all for me.
Anyone else notice that after updating to Android 10, all the necessary Wifi Calling software is just baked in now?
I have the korean SM-N976N , Note 10+ 5g and am on USA T-Mobile. Now, on the Korean Note 8 I had to make a custom CSC patch which included some software from the F variant as well as the U T-mobile variant (as well as delete a Korean feature) to get Wifi Calling working.
However, on this 10+ 5g I haven't had time to root or work on a CSC patch to get WFC, but after updating to Android 10 a few days ago, it is just baked in by default now and works just fine. I did have to go into the Wifi Calling menu and change the preference to Wifi, but it is definitely connected and works great.
Now I'm really not sure rooting is even worthwhile anymore... adblock would be nice and CSC feature customization is also great but... everything just works now (minus phone-app Samsung Pay of course, but rooting wouldn't solve that).
-------------
Anyway - anyone else notice this? Wondering if AT&T WFC will work now as well.
KT- Hey! I ALMOST got a Exynos Note 8 a while back, based on your experiences fixing it for T-mobile. Now I'm seriously considering the Note 10+, because it seems even more US friendly.
There's been some talk about Carrier Aggregation. Has there been any progress? Does it REALLY matter? How slow is "slower" gonna be? Would I notice if I didn't have a US version right next to me?
I'm actually thrilled that the Wifi calling just works now! That becomes a huge issue for me once a year, when I travel to the deep Boonies to see my family.
Also, I'm thinking of getting the F/DS. Would it be better if I track down the N, like I believe you have?
Long time listener, first time caller. Thanks so much!
How has your service been? On my N975F, its been ok. Slow data speeds, and weak signal, have been issues ive been dealing with. Im also using on T-mobile in the US.
What about 5g? Did u managed to get it working? I live in China and technically n976n has to work on n78 band but it doesn't
My Max 3 is on MIUI EU ROM 10.x (Android 9.0) and I'm using it in India (I've also used it extensively in US).
The call quality, that has been way below average in US, has been terrible in India and has come to the point where I'm constantly asking people to let me call them back on Whatsapp instead (which isn't even an option is many cases - service calls etc).
Though I guess it's because this phone was never intended for India/US release and doesn't support some bands, is there still some solution available? Alternate radio I can flash etc, to make this otherwise phenomenal phone usable as a phone?
