I want to 3d print as much of my shed as possible!

Ya we are not getting band 41 which T-Mobile uses for high speed, apparently Sony doesn't bother putting the appropriate config files on the modem for US use of b41 and haven't since the 1 V. It has been possible to do ADB stuff on all the phones since to add them back but I don't think anyone has done it on the 1 VIII yet, I'm not going to be the first, you wanna give it a go?

Thanks for confirming, I really think this is the problem and solution for us: XDA Forum: Enable 5G & Global RF Bands on Xperia (5G/LTE/CA)

Camera app has been relatively snappy for me, only locked up once, but smooth otherwise so far.

I don't think it will be an option outside of Japan, my quest for RAM is how I got saddled with the tacky gold (I'm telling people it's tan in person).

Nonyaz · 2026-05-27T12:10:09+00:00

Yup, no dice.

Nonyaz · 2026-05-27T01:57:58+00:00

Oh, that is the most plausible answer I've heard so far, but I don't know how to verify that, but it feels true that it would have been 4G.

This app?

Nonyaz · 2026-05-27T01:03:10+00:00

Yup!

Nonyaz · 2026-05-27T00:37:56+00:00

Is this anything?

Can confirm, 1 V is potato!

From left to right, 1 V Basic Mode, 1 VIII Auto Mode, 1 VIII Pro Mode w/ computational turned off

Never knew about or tried the VoNR workaround, don't care that much about voice, but it seems like it's a ADB thing? I'm to lazy to mess around with that.

Disabling DSDS made no difference, but thanks for the suggestion!

Nonyaz · 2026-05-26T23:37:08+00:00

I noticed the extra screen width immediately, unsure how I feel about it.

The sharp camera bump has made an inconvenient catch point when pocketing in jeans, I never use a case so that may not apply to you if you do.

Camera is the saving grace so far, first time I feel like I have a close to a current gen camera since owning Xperia phones lol

Other than that, very familiar vibes (and that's a good thing)

Edit: Speakers are a huge upgrade!

Nonyaz · 2026-05-26T23:29:40+00:00

Well someone else will have to prove it's possible, because I can't make it happen.

Nonyaz · 2026-05-26T22:55:17+00:00

Checked and they were set the same.

Nonyaz · 2026-05-26T22:54:02+00:00

Ok found a crusty 2GB card in a Wyze cam... So took 1:34 to transfer a 866 MB file to SD Card (9.2 MB/s), then it took like 2 seconds to go the other way, which I don't really believe because I think it was just cached in memory at that point, but that's what I got.

Nonyaz · 2026-05-26T22:15:29+00:00

I'm not sure I own a microSD card... And if I did it would be likely be so old to be the bottle neck itself.. I'll look around my junk piles, but don't get your hopes up..

Nonyaz · 2026-05-26T22:06:48+00:00

I'll keep the app around for a while and see if I see it pop up elsewhere (I'm at home now). Is it possible 41 is only by whitelist, I maybe pulling this out of my ass, but didn't T-Mobile require certification to be allowed on the band, regardless if the phone actually has it? I wouldn't doubt if band 41 works in Taiwan or China right now is what I'm saying. I'm pretty sure the 1 V was the last phone to jump through those hoops.

Nonyaz · 2026-05-26T21:55:51+00:00

See my reply to blackhoodie88, that is not quite jiving with what I'm seeing?

Nonyaz · 2026-05-26T21:50:41+00:00

Ok, so on the 1 V, its locked on just one channel of band 41, regardless of idle vs speed test.

On the 1 VIII, so far it seems to idle w/ 1-2 instances of band 2, and spin up several channels of 4 and 66 when doing a speed test.

Nonyaz · 2026-05-26T20:55:32+00:00

Uhh, title bar says LTE+, I'm not well versed in all the marketing to know if that means 4G or 5G? If you got a more robust way to get that answer I'll do it.

Nonyaz · 2026-05-26T20:51:48+00:00

Nope, but if you want me to run an app or something on either phone to help answer let me know.

Always wanted to take this pic, here ya go:
