General Caution Xperia 1 IV USA version XQ-CT62 bootloader unlock not allowed!

[Hurt Copain]

Can I ask which provider you have? That you are getting 5g? Also which version did you buy? Thanks

T-Mobile. Also use Verizon..Both in the USA. Work fantastic. Bought the US version first. Returned. Too much money for the same device but a unlockable bootloader. That was '62. Bought a 72'. Running beautifully. Kirisakira kernel.. added aosp mods via zygisk and have some added customization.

I also returned the US and I'm gonna buy 72 how's signal and speed for you on TMobile? Also are you able to signed up for Bravia core?

Signal is great. No issues. Actually I had the same speeds on the US model, 100mbps-400 depending on the area. I have not see anything about bravia core. Will look into that and see.

That`s good, in my area we only have the 71 band for real 5G, and my CT72 would show 5G, but I could only get 20mb download, but when I had the CT62 that actually had the 71 band, I was able to have download speeds of 250mb,

Hi been lurking around, im on att with ct72 taiwan version purchased from ngpstore getting around 50-200mbps, the phone says 5g on top of screen but phone is not actually not connected to any NR bands that i seen. It gets speeds a bit faster than my xperia 1 ii at51 did, probably because its provisioned to 5g allowing faster lte speeds maybe?. Phones been great so far , been curious what provider does the ct62 gets actual mmWave with though or if it even connects to att NR 5G

Hey, few questions if you don't mind.

1. Does the Asia version (72) have bands 71 and n71? Can you confirm with an app like LTE Discovery that shows you are connected to LTE and 5G band 71?
2. Is the phone IMS registered (*#*#4636#*#*) and do you have IMS services including VoLTE and WiFi Calling?
3. Do you have VoNR? Set the radio to NR only in *#*#4636#*#* menu and try to make a call.
4. Do you have VoLTE/VoNR hand off? Meaning if LTE or NR signal is weak, phone calls will seamlessly hand off back to the better signal without dropping the call?
5. Do you know what advantages the US model would have versus the Asia model in the US? What is the Asia model firmware missing that would be in the US firmware?

Would really appreciate your time with checking these! Thank you in advance!

Ct72 doesn't have band b71 and b71 it has b66 and n41 and b41
Also volte works on TMobile wifi calling doesn't work for me unless if you are on Google Fi from what I was reading
If I set the radio to NR only i can't make calls also the difference between ct72 and ct62 is the bands supports ct62 has b71 and like 3 mmwaves which are 260 and 261

Late to the party, is the days of unlocking the bootloader through other-than-official means no longer possible?

So wait .. the USA variant on Google Fi will get provisioned for Wi-Fi calling?

I received my USA variant phone last week and so far I really like the phone coming from the LG v30 Plus. Not having Wi-Fi calling while shopping is killing me.

I heard that Google fi was the solution but when I called them they asked me for the make and model of phone that I have and I even went on their website and they claim this phone is not compatible. So if you're telling me it does work on Google fi I will be signing up with them as soon as possible.

From what I been reading yes Google Fi works with wifi calling

 

[s1dest3pnate]

Yeah this is my understanding too is that WiFi calling will work with Google Fi.

Love this phone. The only downsides for me are locked bootloader, no WiFi calling, no visual voicemail, and dim flashlight.

Visual voice mail also works with Google Fi.

You have US model? I bought it also but decided to returned it and buy ct72 international one because of bootloader and price difference lol

Yeah US model. Having Band 71 is a must for me.

 

[hnt20]

yes, US model CT-62 supports band 71 with no issues.

CONFIRMED. I switched to Google Fi, Wi-Fi calling works 100%.

Funny thing though, Google Fi on their website will tell you our phone is not compatible but in actuality it is 100% compatible.

Does visual voicemail work too?

Does visual voicemail work too?

To be honest I haven't had anyone leave a message yet.... However, according to Google Fi yes, it's built into the Phone App. See attached photos.
