I no longer have access to my cam4’s after the latest camera update. They are no longer compatible with my Samsung tablet or the app. Please design an app that is inclusive with older devices. I was looking forward to buying a few pan cams too. Now my cams are basically bricked as I’m not able to get a different device. Was told ‘unfortunately there is no work around’.
Welcome to the Forum, @jabbatoonces! 
What app and firmware versions are you using?
When posting about issues related to the app or firmware, it can be helpful to others within the community if you include specific versions. Saying “latest” can be somewhat vague, depending on which specific devices you’re using (both Wyze and mobile) and when someone happens to read your topic.
I’m not sure who gave you this advice:
I don’t think that’s entirely accurate. Even though newer firmware versions for some Cams now (and likely more in the future) require newer app versions, it’s also still possible to flash the firmware for some Cams back to earlier versions. In your case, you could consider downloading a prior version of Cam v4’s firmware and then flashing that into your affected Cam v4s. If you choose to attempt this, then please take note of these things:
Please be aware that this is primarily a user-to-user support community and that someone from Wyze may or may not see your topic. If you want better visibility for your concerns from Wyze within the Forum, then you could consider posting a reply to whichever topic in Wyze News corresponds to the firmware version that you believe is the cause of your problem. Again, it would be important to note both your firmware and app versions when doing so.
If you read the release notes it tells you that you must have a certain app version to run the firmware.
If you’re using an old tablet that can only run the 2.5 app (the 32 bit version) then yes you’ll lose access with this firmware. So you either need to manually downgrade the firmware or replace the tablet with a 64 bit one. Note that at some point the 2.5 app is going to be completely useless, it is gradually getting made obsolete by newer security protocols being released in newer firmware. It is not officially supported anymore.
I think the key question is - how ancient of a phone (and it’s OS) are you using? If you are using a really old phone, more and more software will not work with it. Pretty much every piece of software has a “this is the oldest OS that this will work with”. At some point it simply is not practical to support some particular OS. For example, I run a computer controlled Christmas light show at my house. In 2022, the then new software version would no longer work with Windows 7 or 8 - required Windows 10 (or now 11).
I have android pie and the cam4 firmware 4.52.9.5332. The app is no longer available on google play so i went on APKpure and redownloaded the app v 3.6.7.694. I tried flashing an older version of firmware (recovery_wcv4_4.52.9.3415.bin.zip) like Crease mentioned above and followed the directions to no avail. Will try a smaller memory card.

That’s Android 9.
It is, but Google Play Store won’t offer it to your device because your OS doesn’t meet the minimum requirements. Current versions of the Wyze app require Android 10:
Thank you for including information about your firmware and app versions! 
That helps to explain your situation:
Those are incompatible:
In addition to trying a smaller card (32 GB or smaller), please do make sure that it’s formatted FAT32. Some users have reported that having other things on the card often causes problems, so you may have your best chances of success by using a freshly-formatted card and ensuring that the only thing you copy to the card’s root directory is the single .bin file that’s necessary to flash the firmware. You must download the .zip file from Wyze’s repository, decompress it, and extract this .bin file from the archive. The recovery_wcv4.bin file should be the only thing you put on the microSD card before inserting it into your Cam v4.
I wonder if you’re trying to rename the .zip file because of Step 4 in the instructions. Although Wyze recently edited the instruction to clear up some confusion, that particular Help Center article still has problems, and the instruction about renaming the extracted file seems unnecessary and potentially confusing.
Another thing that can be helpful is using a power strip. Holding in the SETUP button while plugging in the Cam can be tricky for some people. When I have to flash a Cam, I plug it into a switched-off power strip, insert the microSD card into the Cam, hold in the Cam’s SETUP button, and then flip the switch on the power strip while continuing to press the Cam’s SETUP button for 3-6 seconds or until the status LED turns purple.
Please note that flashing back to older firmware should be considered only a temporizing measure. You’re likely to have better results with your Wyze products and your mobile experience overall if you can make plans to replace your phone with something running a currently supported operating system, particularly since Android 9’s last security update was released over four years ago.
Please also understand that I don’t fault anyone for using older technology, especially if part of the goal is to reduce e-waste and keep things out of landfills, and I noted my own uses of older tech in a topic I linked above. I just think it’s important to understand the risks involved (e.g., missing important security patches) versus the benefits of using something more current.
Finally got around to rolling back the wyze4 cam. Used a 2 gig card and pulled both .bin files out of the archive. It was successful! Thank you so much for your help. Ive always loved Android Pie and am happy i can use my tablet until it dies. 
My old phone is still on Oreo (8). But the writing is on the wall, now my v4 doesn’t work with it and the Panv3 has limited functionality on it too. But I use that for backup purposes or to try to see when an issue is app related or not.
Take a look at the Lenovo tablets, they go on sale frequently for very good prices.
The Onn (I believe Walmart exclusive?) tablets are cheaper and halfway decent for light needs, but you need to make sure the one you get runs an 64 bit Android OS, I believe some do and some don’t.
Obviously Samsung makes really nice, powerful ones, but they have prices to match. Though the low end ones sometimes come up at a good price and are an attractive value at that point, usually around the time they’re releasing a new model.
Thanks for taking the time to post an update. I’m glad you were successful!
Like I said, I’m still using older tech, including a moto g⁷ running Android 10. That one’s mostly for listening to podcasts and testing, and so far it’s still running the latest WyzeBeta app.
