I work in the electronic department of a Walmart. The new tablets have rolled out in my store, at least. I am not working today so I don't have the specks, but, at least for the 8", the price is lower.

This apparently comes in 4 colors, gray, yellow, purple, blue. $79
This is "charcoal", i.e. gray: https://www.walmart.com/ip/onn-8-Tablet-32GB-2022-Model-Charcoal/530143567

I've had the original Onn 8 (not the Pro) on my dash for a while.
I think the speed is an improvement over my old Nexus 7 (2013).
Still, the GPS leaves something to be desired in that it's so inaccurate and there is (apparently) no magnetometer.
If you're stopped at a light Google Maps will go wacky telling you to pull a U-turn or take a right or take a left.

Still, I think I'll pick one of the new ones up for the dash (gray) and maybe another for news site browsing (yellow).

I got one of the new 7 inch tablets and it's pretty slick for a 50-dollar tablet. Nothing fancy removed the walmart bloat via ADB and it gets the job done.

(2022) 7" ($59): https://www.walmart.com/ip/onn-7-Tablet-32GB-2022-Model-Charcoal/169995658
(2022) 8" ($79): https://www.walmart.com/ip/onn-8-Tablet-32GB-2022-Model-Charcoal/530143567
(2022) 10" ($109): https://www.walmart.com/ip/onn-10-1-Tablet-32GB-2022-Model-Charcoal/126787849

Are you sure that you got the new (2022) 7" model? The new one is $59. The 2021 model is still selling for $50.

The most critical is getting rid of the Walmart icon on the navigation bar:
Code:
adb shell settings put secure sysui_nav_bar 'space[1.5WC],back;home;recent,space[1.5WC]'
Play with the 1.5 number if you don't like the spacing.

Many stores may not have them yet. They may have them, but if I recall, the actual mod reset for them is in the future, therefore many stores have not put them on the sales floor, yet.

Ok. My bad.
I just don't know why they would mark down a new model (with limited availability) to $50 (MSRP $59) when they have stacks of the old "Gen 2" 7" for $49 in stock.
I thought that was odd, myself. I did notice many older models we have out are priced higher than the new ones.
Personally, I have stayed with my 2, 1st gen tablets, because they were easily rooted and have TWRP ported to them, thanks to @diplomatic .

Is it just me or is Gen 3 lineup not always an upgrade? The 7 gets a bump in storage and battery life but the 8's resolution is lower and only has a quad-core CPU rather than an octa-core. I can't find specs on the 10 at all but one of the reviews (that reads like they copy-pasted PR from Onn) says it only has 2GB of RAM.

Edit: Seems I'm comparing the 2022 models to the older Pro models for the 8 and 10. Guess I'll wait for Pro models to roll out.

Maybe you could inform your superiors that Walmart has been violating the GPL license by not providing kernel sources to their tablets -:(. You will be doing this hacker community a favor and also helping Walmart be in compliance with the law.

Sorry, but this will never happen. I have had these cheap Androids tablets since Android 5.0, (Nextbook) and they will never do this. I believe this does not apply to China. They won't do that.
By the way, these new generation 3 device should be now available in Walmart stores.

So, here it is. I haven't even powered it up yet. Shown with the main "tin can" removed.

Interesting to note, the test points are labelled well, there is a reset TP.
The 20 pin at the bottom is the USB Type C and the speaker.
The 30 pin is the IPS LCD.
You can see from the USB test points at the bottom (DP, DM) that this is USB 2.0
Interesting, at the top there is an unpopulated micro USB 2.0 connector. (Is that a separate interface?)
Lots of test points, maybe UART on that 6 pin or JTAG?

Edit: Interesting. I plug it in and it shows for a few seconds 0e8d/2000 Media Tek PreLoader
Yes, but the one you want is 0e8d/0003 which is the actual boot ROM
Ah, ok, there are 4 buttons, VolUp, VolDn, Power, Reset. 3 buttons and a hole for Reset.
Android "Go Edition" Android 11
Build number x 7 for Developer mode, System > Advanced > Developer > OEM unlock, ADB enable
There is accelerometer/auto-rotate but no compass. Compass is good to keep Google Maps from spinning when you're stopped.
It uses a super (dynamic) partition and has FRP.

So the top, non-existent USB connector seems to be in parallel with the bottom connector, although it seems that parts haven't been populated so that the two data lines don't go through.

There's a stupid (depending on your taste) "Entertainment space" which is a multicolor tab that is always present on your homepage.
Yes, you can disable "Entertainment space" and the tab turns white, but you can't get rid of it.
Like the Google search bar (that you can't get rid of) this seems to be part of the Launcher.
I just set my minimalistic "Lunch" app as the Home app.

Edit: The model is 100071483
The 8" Gen 1 was MT8163, Gen 2 & 3 are MT8168
Maybe the only thing different is colors?

I've been having fun with this.

I used bkerler's MTKClient to pull the boot image. https://github.com/bkerler/mtkclient
It's easier to do this in Linux, I used a spare Raspberry Pi.
Save your data plan (if you have one), don't use the GUI version and don't just "pip install -r requirements.txt".
Use requirements.txt as a guide and just pip install them when the program complains.

If you wanted you could let Magisk take over from there.

I've pulled the kallsyms out of the kernel and made a few mods to the code.
I put in an "empty" vbmeta too.
Code:
100071483:/ # getenforce
Permissive
