No need, since the custom boot animation applying method is available, by the way why are you replying to a post that is ages ago.

Don't you think it would be solved by now.

Okey now! We have some ROMs that I've tried and tested to be kinda stable! Especially LOS 14.1, LOS 15.1( though 15.1 has serious battery drainage) and also ROMs like XenonHD!

But! Does anyone know why they're not made official?

:cowboy: **Feel free to correct me! **
[Xiaomi Mi Max 2  Questions & Answers] jbmc83:
oh thats an easy one, actually:

whether or not a rom is "official" is not only limited to it being bugfree, but also to the developer's willingness to actually make it official.

so a custom rom can be bugfree and stable but still unofficial as long as the dev chooses to keep it that way.

so why would a dev do this? also easy: making a rom official means the dev obligates him/herself to follow the official rom guidelines and keep it up to date no matter what. however, keeping a rom unofficial allows the dev to follow his own timeline and decide for himself whether or not hed like to keep the rom updated.

so all in all, the unofficial status allows way more flexibility for the dev.

for us as users the "official" status doesn't necessarily mean a better rom. a lot of custom roms for the MM2 are already bugfree and stable, so for us it wouldnt make any difference to make them "official" other than the name...

I'm using T-Mobile in the US and had WiFi calling and VoLTE available on my S8+ but it's not an option on my H8266. Doing some research it would have to be approved by T-Mobile for it to work with either of those and so far the XZ2 is not on the list. I found this information helpful, http://www.spectrumgateway.com/compatible-phones
[Sony Xperia XZ2 Questions & Answers] hnt20:
Thank you for the info. Sony has been ignoring this fact for a while, none of the premium phones work on T-Mobile US VoLTE. It is not a certification matter as Chinese phones such as OnePlus work out of the box with T-Mobile US VoLTE making this very clear a Sony issue.

If you are on T-Mobile USA, you will have very limited coverage due lack of VoLTE support. Please be aware before you making a purchasing decision with Sony phones.

Hey hnt20!

Yes, all people should know this before buying Xperias while on T-Mobile USA.

I agree. It's essentially INEXCUSABLE that OnePlus, Huawei (Mate 10), and HTC can certify their flagship phones, but Sony can't except for their "barely flagship" compact phones like the U.S. XZ1 Compact (see Connectivity section)??! Given that the U.S. XZ2 Compact page doesn't also mention this, I'd be shocked if ppl on the xda page for that phone confirmed it actually had it. Same goes for the U.S. XZ2.

I'm VERY confused by that btw hnt20. How the F is it that OnePlus' phones have T-Mobile VoLTE enabled OUT OF THE BOX w/o certifying it, but Sony's phones can't? HOW is this possible?? lol So now I wonder, are HTC and Huawei certifying or no?? My unlocked HTC 10 from last year had VoLTE enabled, and my dad's OnePlus 5 does too, so I know that's all true about them having it.
[Sony Xperia XZ2 Questions & Answers] petrutms:
I have my Xz2 from Orange network România and wifi calling and volte is working excellent.
[Sony Xperia XZ2 Questions & Answers] RockStar2005:
The issue is here in the U.S. petrutms. T-Mobile states that if a phone OEM doesn't "certify VoLTE" on their network (which costs time and money), then it won't work on their network. But what I don't get is why ppl say OnePlus for example doesn't certify it yet I know for a FACT it works b/c my father is on my family plan with T-Mobile and his OnePlus 5's VoLTE works just fine.
[Sony Xperia XZ2 Questions & Answers] nathlynn2201:
I'm unsure about US. Since starting the post I've managed to get WiFi calling working but that was just from an update. Will try phoning EE in the UK and see what's going on. Cheers
[Sony Xperia XZ2 Questions & Answers] RockStar2005:
In other countries like the UK, you guys don't have to worry about stuff like this, so be grateful. lol Sony makes the best phones, but the ppl running the show there are absolute f'ing idiots. lol I have the LG V30 now and love it for the most part, but I would love to upgrade to the XZ2 Premium when it comes out. But if it doesn't have T-Mo VoLTE, then Sony Mobile can seriously go F themselves.
[Sony Xperia XZ2 Questions & Answers] hnt20:
Hi RockStar2005, the phones comes pre-certified as long they have Qualcomm Chips that come carrier pre-certified. As a result, Chinese phone makers don't have to go through certification process per each carrier. The same goes for Sony, but Sony is F*ing with US market and deliberately disabling VoLTE and VoWiFi for T-Mobile USA. This has earned Sony my full disrespect in all of their products (not just smartphones)
[Sony Xperia XZ2 Questions & Answers] RockStar2005:
hnt20,

Interesting. But aren't ALL Qualcomm chips pre-certified since like EVERY flagship phone that comes out for the most part runs on them??

But why on Earth would Sony Mobile be doing this?? It sounds like more work for them with no benefit.

They did certify or "let" the XZ1 Compact (U.S. version; see "Connectivity" section) have T-Mobile VoLTE though. But nothing else since they

idiotically

went "unlocked only" back in 2015.

I don't get why I was told this (I think by T-Mobile directly?) if it's not true. So confused!
[Sony Xperia XZ2 Questions & Answers] hnt20:
No idea, one can only guess that Sony is taking it personal against T-Mobile. Or Sony has some legal issues going on. Though, we do know the following:

- The fact is Sony is NOT transparent about disabling VoLTE and VoWiFi with T-Mobile USA.

- The fact is Sony does not work with T-Mobile USA VoLTE or VoWiFi

- The fact is Sony works for the reset of the world for the same features

- The fact is Sony is using the same chip set that are pre-certified and work with Chinese phone makers.
[Sony Xperia XZ2 Questions & Answers] RockStar2005:
All of that seems true, but then why would they certify or enable VoLTE on the U.S. XZ1 Compact then? THAT is the point that is driving me insane!! lol

Also, the last several phones were GSM only, and do not work on Verizon or Sprint as they are CDMA. So is it really fair to say they do not want to work with T-Mobile on issues?
[Sony Xperia XZ2 Questions & Answers] augie7107:
I'm on AT&T so VoLTE not even available in my area but does it really make that much of a difference? Call quality on this device is fine.
[Sony Xperia XZ2 Questions & Answers] RockStar2005:
Hey augie!

VoLTE not only strengthens the call reception, it also helps connect calls faster as well.

The issue on T-Mobile is, you NEED VoLTE to be enabled or else you can't access the superior lower bandwidths on their network, namely Band 12 (700 MHz) and Band 71 (600 MHz). Instead you only have access to the higher (1000+ MHz) bandwidths, which are more standard but not as great. Band 12 and 71 both individually offer two great things: 1) Twice the range of the higher bandwidths and 2) FOUR times the capability of penetrating through buildings/walls.

So yeah, it does make a difference. I'll give you an example. Last fall my dad had the older Xperia Z1s (a T-Mobile exclusive version of the Z1) which came out before VoLTE was standard on T-Mobile, and it didn't have it included. My dad was visiting my uncle (who has Alzheimer's) and he went off into a forest near by and my dad was with him and they ended up getting lost. My dad tried to call my aunt, but couldn't get reception. I found out later after checking T-Mo's Band 12 map online that although the area had no regular T-Mobile reception, the area DID in fact have T-Mo Band 12 coverage. So if my dad had the phone he has now (the OnePlus 5, which I MADE SURE had T-Mo VoLTE enabled) back then, I have GREAT confidence his call would've gone through. It was summer and they're older, so they were susceptible to heat stroke, etc. Fortunately, nothing happened, but I will no longer tolerate a phone for myself or my family that doesn't have VoLTE.
[Sony Xperia XZ2 Questions & Answers] hnt20:
We need to group together and file a class action law suite against Sony and ban their sales in the US. There is a clear case against Sony.

The Federal trade comm. should be aware of the marketing scam and consumer depiction going on. Sony and T-Mobile must be list in the law suite and provide their deposition and statements. We should start with fact gathering process.

Sony smart phones sold in the US don't work with US major carriers and such info is not communicated or marketed. Sony should be banned and consumers should be compensated period.
[Sony Xperia XZ2 Questions & Answers] RockStar2005:
I am with you 100% hnt! But again, how do you explain the U.S. XZ1 Compact having T-Mo VoLTE on it then?

But aside from that, yeah it's total BS b/c many people who have T-Mobile buy their phones not knowing this, end up realizing that people around them often have better reception than they do, then end up leaving Sony for another company. But I bet even more often, ppl never realize what they're missing out on and keep using their phone, like my dad with his Z1s (see my last post).

We have to get our facts straight though. You're saying certification isn't necessary and it's all based on the Qualcomm chip. But that contradicts everything I've read thus far.

Sure thing. Glad to help!

Likewise. Hope all is well with you!

---------- Post added at 10:59 PM ---------- Previous post was at 10:58 PM ----------

I don't know. Probably not.
[Sony Xperia XZ2 Questions & Answers] KOLIOSIS:
Just used T-Mobile (US) DIGITS to make a phone call to a landline,using the H8296 model:

I disconnected WI-FI before making the call & the signal dropped from 4G LTE (Band4) down to HSPA+.

Once the phone call completed,the signal jumped back to 4G LTE Band4.

When keeping WI-FI on during the call,no change in connectivity,stayed on Band4.

IDK if all of this is SOP or of any consequence to the OP topic,just giving my usage as best I can/hoping it helps clear any questions up.

FWIW,my area has Bands 2/4/12,I'll check on my way home this evening,see if I pick up Band 12 along the way,2&4 are no problem.
[Sony Xperia XZ2 Questions & Answers] RockStar2005:
Sounds like it didn't work then if you remained on Band 4 during the call.

Yeah find an area that had Band 12 and try it again there. Good luck!
[Sony Xperia XZ2 Questions & Answers] km8j:
Pretty sure we have band 12, its just data only.
[Sony Xperia XZ2 Questions & Answers] RockStar2005:
It's supposed to be both though. I mean, if you have T-Mo VoLTE anyway.
[Sony Xperia XZ2 Questions & Answers] KOLIOSIS:
Yep,getting Band 12 data,no problem. :good:

FWIW,this phone is also provisioned for Band 66,it'll be years before I see it (2019-20). :rolleyes:

Whether on WI-FI or not,when in a Band 12 area,I place a call & it drops down to W-CDMA.

Just as with Band 4,Band 12 picks up after completing the call.

Yeah,something's apparently going on behind the scenes w/the US carriers & Sony:

The XZ2 Compact works on VZW,to what extent,IDK,but,the no VoLTE/Vo-WI-FI is now the sole owner of the Sony WTF Crown,now that the (US) disabled FPR is history..........

Otherwise,I have few complaints,it's (XZ2 H8296) a great phone.

The weirdness with this affects myself little,but,I do wish Sony would take care of this matter once & for all,for everyone's benefit.

Perhaps there's a root solution to enable one or the other (or both VoLTE/VoWi-Fi)..............
[Sony Xperia XZ2 Questions & Answers] RockStar2005:
Yeah, that means no VoLTE then. Band 12 should be present DURING the call if VoLTE is enabled.

Yeah, other than this issue, all the Sony phones have been great. But this issue is still a big one.
[Sony Xperia XZ2 Questions & Answers] Berzerker7:
I think we can conclude that VoLTE and Wifi Calling will not be available for the XZ2 or XZ2c any time soon on T-Mobile US. If you're within your return period, the most "damage" you can do in this situation is to return your phone back to the retailer and get your money back. If Sony sees the demand, they may do something about it, but the fact that only the XZ1c was certified and every other device was not, I'd be hesitant to think it would be. I'll most likely be returning mine to Best Buy.

---------- Post added at 12:57 AM ---------- Previous post was at 12:56 AM ----------

US Unlocked purchased from Best Buy.

Yep, I'm on T-Mobile US. No VoLTE or WiFi Calling here (as expected)
[Sony Xperia XZ2 Questions & Answers] chili_red:
I just finished chatting with Sony USA support and here's what was said, "I asked in the opening question where the VoLTE and VoWIFI settings were as I was unable to find them to turn them on, I gave her my make and model to make sure we were chatting about the correct phone"

Paula C

Thank you for the information, Sir.

As I understand you are not able to enable VoWiFi, right?

Steven

That is correct.

Paula C

Alright, I understand you, actually the device has the feature, but it must be enable by the carrier, Sir.

Steven

To clarify, I need to contact the carrier to get this resolved?

Paula C

9:36 am

Yes, Sir. They are the only one able to enable the option.

So it appears T-Mobile does have to provision this for the phone itself.

Here in MS our T-Mobile service really sucks, so I've ordered a Redpocket sim for ATT and going to give that a whirl. I had Cricket here before T-Mo and the signal was way better, they just cap their download speeds.
[Sony Xperia XZ2 Questions & Answers] RockStar2005:
Hey chili,

I can tell you right now with 100% certainty that THAT is a BS answer. lol If you call or contact T-Mobile and ask them to enable it, they will just refer you to the manufacturer. T-Mobile will tell you that "Because the phone is not sold through or by T-Mobile, we can't help you." But go ahead and try if you wish.

When I bought my Z3 it was locked and sold by T-Mo, so I had all the features. But back then my area didn't have VoLTE so it didn't matter. I'm not even sure T-Mo had Band 12 at all during the time I had the phone, but maybe. But again, my area (Chicago) didn't get it until Summer 2017. lol See T-Mo Band 12/700 MHz official map here to check your area.

Dahmn! Yeah from what I can tell, like NONE of MS has Band 12! I don't blame you for switching over to AT&T. lol Thing is, I don't know if you'll get VoLTE even if you do through them, but please let us know if you do, cuz that would be awesome!
[Sony Xperia XZ2 Questions & Answers] KOLIOSIS:
Just to pile on here, Sony's Chat/Reps are totally useless on any subject. Their SOP, regardless of subject matter, is to pass it along to someone else. I'd honestly be surprised if you could get them to agree that the sun will rise tomorrow.....

Haha yup!!

hnt20 had the RIGHT idea........................class action lawsuit!!!!!!!!! Rot in hell, Sony Mobile!! LOL :good:
[Sony Xperia XZ2 Questions & Answers] chili_red:
Well MS won't get TMO band 12 support anytime soon, "if ever" there's a small regional carrier here "CSpire" and they own all of the 700 band spectrum in MS, they aren't sharing with anyone. That's directly from my neighbor who's a program director for CSpire.

Even if I don't get VoLTE or VoWiFI on Redpocket I'll be happy with the better coverage ATT provides here, I'll let you know if I do. My wife is currently using Cricket, she gets HD calling on her G6 but haven't actually poked around the phone to see if VoLTE is on there. I'll do some checking on it when she will lets me take the phone from her for a few minutes.

---------- Post added at 12:59 PM ---------- Previous post was at 12:54 PM ----------

He clarified, CSpire has the 700A spectrum tied up just band 12, not band 17 that ATT uses, this is only for the MS area too.
[Sony Xperia XZ2 Questions & Answers] RockStar2005:
Ahh I C. Ok. That totally sux, but makes sense. Your neighbor would know for sure too.

Yeah here in Chicago, one of the local TV stations and/or AT&T (not sure) owned that spectrum, so T-Mo had to work it out with them. That's why we didn't get activated until last summer when it should've happened like 1-2 years before that!

Ok cool! Yeah if you get AT&T let us know if you get VoLTE on your XZ2 or not. Before I thought you would for sure, but now I'm not so sure.

Band 17? Oh that's AT&T's 700 MHz!! Had to look it up to make sure. lol Well regardless of the band, if you get VoLTE on your U.S. XZ2, that would rock!! I really hope you do.
[Sony Xperia XZ2 Questions & Answers] afcor:
I can confirm that this is exactly what T-Mobile told me in a chat session yesterday...
[Sony Xperia XZ2 Questions & Answers] RockStar2005:
Haha yeah. But I ultimately blame Sony Mobile for this nonsense.
[Sony Xperia XZ2 Questions & Answers] afcor:
And it's getting returned today, for these and other reasons. Senseless paying $800 for a flagship that doesn't have basic features enabled. It's too bad, really; I wanted to love this phone and I really do think it's beautiful and feels great in my hand...
[Sony Xperia XZ2 Questions & Answers] RockStar2005:
I don't blame you afcor. I'd be doing the same thing in your shoes.

I actually do like the new design as well, and the phone has a lot to offer, but there's a certain standard that we deserve to have met that Sony Mobile isn't, and that fact can no longer be ignored.
[Sony Xperia XZ2 Questions & Answers] afcor:
I sent them a strongly worded email, about which I'm sure they will be quite concerned... Next up Best Buy, for securing exclusive resale of a flagship phone and then only offering it via online sale. If they had the phones in store, I'd probably consider just exchanging (issue with the USB-C port in which the cable will not fully lock into place), but I'm not going to return and wait several days for them to get another in stock.
[Sony Xperia XZ2 Questions & Answers] RockStar2005:
Nice. I did the same with Sony Mobile about a month ago. Prob my 2nd strongly-worded e-mail. lol Here's a shocker: THEY NEVER RESPONDED!! lol

So the XZ2 wasn't on display in the stores? May just be a matter of time. The one by me usually gets the flagships and displays them. They had the XZ Premium and XA phones of last year. Sometime soon I will go back and see if they have the XA2/XA2 Ultra and also XZ2. It would be nice if they get the XZ2 Premium as well and display it, even though the odds are I won't buy it since I know the odds that Sony Mobile will actually give it T-Mo VoLTE are low at best.
