Anyone flash it?
What's working and what's not list can go here as well as discussion.
I'm gonna wait till Betas but would love to see some screenshots and here some impressions.

Would be nice to know if Magisk Canary is working with the Developer Preview (on Pixel 5).

Initial thoughts...

No issues discovered, yet.
- Wifi speeds are on par with the February Android 11 build (see screenshot)
- T-Mobile 5G speeds (Boulder, CO) are also on par with what I was previously seeing (see screenshot)
- No issues sending/receiving texts/phone calls/Emails/Slack messages
- Bluetooth connection and functionality with my Galaxy Buds and Galaxy Watch Active2 are solid
- Google Smart Home device controls are working (HUE lights, Nest cameras, Google Home Hubs, Nest thermostat etc.)
- Camera quality for photos & videos don't appear degraded
- No noticeable stuttering or hiccups (yet)


Still need to test:
- Android Auto
- Battery life
- Longer term snappiness/smoothness (this tends to degrade over 1-3 days on previous developer previews I've tested)

Side notes:
- I was able to enable the developer flag for the new One-Handed Settings UI but I'm still trying to track down the flag to enable the new larger brightness slider layout.
- Possibly a placebo but notifications tones are much louder/crisper than they were on Android 11 (even at the same volume slider setting). This was a persistent annoyance I had with Android 11 that I attributed to the new speaker setup of the Pixel 5 vs my previous Pixel 4.

@sn0warmy Thanks, great review. Boulder 5g sucks. Denver by Lodo has the high speed one and some other areas nearby. I'm really wondering if we will get eSim + physical sim and 5G. As of now, even though there is a commit that has been merged, we only get 4G if we use both sims. It's obviously not a hardware limitation and I'm not sure why it hasn't been pulled into a monthly other than they are waiting for 12 to enable it.

Do you did new install or updated ?

Clean install.

38mbps is plenty fast for me when I'm away from the house. Though, I will say that 5G signal in this area is definitely hit or miss. I often find my signal falling back to LTE when I'm out and about.

I'm sure it will improve, over time.

Any updates on root for android 12?
Screenshot_20210220-084324.png

Finally managed to flash magisk to pixel5....
However I am only able to boot the patched image (fastboot boot boot.img), if I tried to flash the image(fastboot flash boot boot.img) it won't boot saying "failed to load/verify boot images" which means I lose magisk every time I reboot.
I am fine with that although it's not perfect.
BTW exposed doesn't seem to work for now and the safetynet-fix module is bricking my device.

I ran into my first bug. If I try to change the notification tone in any app other than 'Phone', notification settings force closes. So I'm stuck with all the default notification tones for everything except the system wide default notification tone and ringtone.

I'd advise against plastering your IP and device MAC address on a public forum...

Yeah 38 is very decent. Have you tried it with 4G for comparison? I have dual sim so I only get 4G unless I temporarily disable a sim. When I test the 4G is faster. I agree, it will improve once they start rolling out mmWave.

flashed and running for me.. 5G working on Verion. I updated (no clean wipe).

Battery may be a tad worse but that's because I'm used to being rooted and optimized.

Havent come across any hard crashes and reboots. I'm making an install video.. then later one on features, sharing experience (after using it for a while as my daily)

Tried dp1 earlier today. Found 1 bug I can't stand which is media playback won't hear in my Pixel Buds 2, I guess it'll be the same with other bluetooth earbuds?

Tried rebooting the phone to see if it resolves it, no. Tried also forget the Buds and redo pairing still the same. I can hear notifications fine but media playback, no. Just silence.

So flashed back to Feb 2021 public build.

I've been using DP1 since Friday and haven't had any issues with media playback, notifications, or voice calls via bluetooth through my Galaxy Buds, Nest Audio Speaker or my car.

    I've got a nice long 3 day weekend, starting now. So I'm going to give this a go and run it through its paces to test 5G, Wifi speeds, Bluetooth connectivity with watch/headphones/car, smart home control, notifications, various apps I frequently use etc.

    Will report back soon.

    I got root working on A12 dp1.1. (yay)
    Userdata will be wiped so take a backup.

    - Install dp1.1 using the Android Flash Tool (flash.android.com) and check "disable verity" and "disable verification" before confirming
    - Patch the boot.img from the factory image using the latest magisk canary app.
    - just flash the patched boot.img (fastboot flash boot magisk_patched_*****.img)
    - reboot. If it fails to boot and asks you to format confirm.

    Universal safetynet fix doesnt work unfortunately. To fix run
    Code:
    adb shell
    magisk --remove-modules
    while booting.
