I mean in UK I saw no one complaining about the s20 5g note 5g etc yet it's an exynos.

But most parts of UK are still space, in my city center is the only place for 5G and only certain parts.

But it's quick

I've done a comprehensive deep-dive into the modem's capabilities. That's not saying much with the available diag tools and data to look at are practically non-existent. The logs I can pull are useless since I don't have those tools. We've only been able to pull out the carrier aggregation combos and bands that are actively offered by a tower. There's nothing allowing us to make a full device report yet. Cellmapper is usable for SA but anchor bands don't always show up for NSA. One thing it does right is band indicators for NSA.

It's not as fast as a Snapdragon X60 or Release 16 like Mediatek. 5G aggregation, TDD-FDD aggregation, and VoNR should all be possible based on its S20/21 siblings' spec sheets, modem dumps, and slideshows but are mostly unproven. What makes the Exynos 5123b better than an Exynos 5123a? We have no clue.

What does this mean for the Pixel 7? The Exynos 2200 modem is still an unknown but Google should adopt the Snapdragon X65 instead.

This is literally all we know without getting into the weeds.

I'm still trying to figure out diag modes for this phone. I can get the modem and serial devices to show up. Per my conversations with cstark:



Everything seems to be controlled by /vendor/bin/modem_logging_control and /vendor/bin/dmd.



Regular invoke can yield usable logs and we can also get the apps started in SHANNON_DM or SHANNON_APP mode after START, but no idea what to do with them.

The Shannon DM version floating around is too old and I haven't gotten a decent scat setup. Airscreen might work but Network Signal Guru doesn't. No tools for this phone are good at the moment.
This website seems to already have some carrier aggregation combinations/bands for the Pixel 6 Pro, but it only lists the ones that correspond to a particular mobile phone carrier configuration, i.e. the supported bands that it reports changes whenever you insert a SIM from AT&T, T-Mobile, etc.

From what you're telling us, it seems that obtaining the actual hardware capabilities is still pretty elusive.

I had 5G as preferred but not covered that well so noticed battery was being hammered and Carrier Services was runtime of 22hrs 3 minutes so switched back to 4G. It looks like the battery was being drained because this was looking for 5G so much

The December update looks like it could be substantial.

Early indications suggest that NR-CA being added. This means 5G signals can soon be combined. Awaiting further analysis.

This would be a major achievement for the modem.

Is this something that's had any developments? I've recently verified my setup w/ scat.py and the leaked shannondm with an older s7 but haven't had any luck with the pixel6 yet. Came to the same spot you are in with the serial port being exposed prior to stumbling upon this thread.

I had tried scat but wasn't sure of the correct flags. Usually craps out when it scans the port.

With respect to Network Signal Guru, version 4.0.3 was finally published today. There still might be some weirdness in dual sim configurations if the 4.1 alphas are any indication. I've found disabling DSDS in the *#*#4636#*#* menu to be helpful.

Looks like Network Signal Guru 4.0.4 now includes 4G band locking for Exynos and Pixel 6. It's pretty crude compared to what I'm used to with Qualcomm but it works.

    Does that matter and why? $900 for tech already outdated by a year... I can understand if budget phone. $900 is not a budget device.

    Sounds like they skipped out on others like inferior panel as well. So it definitely seems Pixel once again is a gimmick phone. And their fans will defend it because of it's gimmicks without acknowledging once again its a phone with pricetags not backed by haddwarw but camera software gimmicks.
    I have never had a pixel device, but I can still say it's an amazing deal. You're someone who expects an exact $1200 Samsung clone for $900. You're either a troll or shallow, no body likes either of those things.

    I am in San Francisco on T-Mobile and live in one of the few locations where there is a hole in 5G service. On the cusp, I teeter between 5G, 4G and 3G when at home. Yes, I am on Wi-Fi when in my flat so this is less an issue.

    However, I've turned off 5G altogether because the modem or software refuses to switch from an unusably weak 5G signal before picking up 4G.

    This was making my phone unusable when walking around in the city playing Ingress. I was constantly toggling airplane mode to reconnect and by the time I do, the portal I was attempting to destroy have been recharged by the enemy. Google has crossed the line when they start messing with my gaming. ;)

    On a positive note, my phone hasn't been snatched out of my hand by thieves so I should be thankful for that. 😂

    In order to get the new technology it would cost more then 900. Sounds like you are trying to compare apples with oranges. If you want the newest tech, then you pay for it. If you think samsung is the greatest, why consider pixel?

    1st gen vs 2nd gen modem from Qualcomm is about twice the difference from certain reviewers.

    Qualcomm modem better than Samsung which is why Exynos this year uses Qualcomm modem. But Google chose the Samsung modem from last year instead. Just because it is not Qualcomm probably.

    So makes a huge difference.

    To you may not matter. To me if I am paying 900$ for a year old tech that is singificantly inferior, and considering this is a phone and the modem is terrible compared to competition, matters to me. Just another way Google continues to give the finger to Pixel users every year they find a way to do that. If this is the case.

    I just like knowing when Google will start to treat Pixel users same level of respect as Samsung with their fans.
    dont forget it also doesnt have the samsung price
