Hello,
I have a problem with my new Polaroid mini projector that runs on Android. Many people have this device with Android 4.4.4, and when I ordered it, I thought mine would be the same (that's what was written on the site), but mine is running Android 7.1.
In the version of the device with 4.4.4, in the "display" settings, it is possible to change the size of the projected screen and thus adapt it to the available space in the room for projection. In my version, I can't do that. I only have a "keystone" mode to manage the projection tilt.
As a result, I have a projection that is too large for my projection screen on the wall... I searched for an app or something that could modify this, but nothing.
Is it possible to change the Android version on my device without issue, and if so, how?
Otherwise, do you know of any other possibilities?
Thank you in advance if you can help me... I don't know what else to do.
Configuration: Android / Chrome 76.0.3809.132

Hello,
You can change the resolution of your projector by connecting to it using "adb" from your computer.
To do this, you first need to enable "Developer options" by clicking 5 times on the "Build number" in the "About device" tab in the projector's settings.
Next, you need to enable "ADB over network" in the "Developer options" tab in the projector's settings.
Then, you must connect your projector and computer to the same Wi-Fi.
Once that is done, you need to download "adb":
https://www.xda-developers.com/install-adb-windows-macos-linux/
Finally, you just need to open a command prompt in the folder where you extracted the adb files and execute the following commands:
You need to replace "x.x.x.x" with your projector's IP address. You can find it in the network settings of your projector. The size is set by the dimensions of the 3rd command (950x720).
Good luck!

Hi Alison,
You posted your question in the
If you want, we can redirect your question to one of the two.
If you want my (non-expert) opinion on the matter, Android 4.4 (Android KitKat) is a system that hasn't been updated by Google for over 5 years now. In terms of security, it’s not great. It’s also possible that if the manufacturer of your device decided to upgrade the embedded operating system to a more current version, it might be to support hardware features that your projector version doesn’t support and which older Android versions can’t handle.
Downgrading firmware can be tricky unless it’s supported by the manufacturer (who provides the firmware image and the procedure for changing from a higher version to a lower one), and you risk ending up with a brick or a nice expensive paperweight.
To resolve your issue with the missing functionality, I would rather advise you to try to obtain more detailed documentation than what you currently have (the manuals provided at delivery are becoming increasingly basic these days and often consist of mere quick start guides) from the manufacturer's website, or directly ask the manufacturer through their customer service.

You posted your question in the
Programming - Androidforum, but it doesn't relate to programming. There’s possibly a
Mobiles - Androidforum we could redirect your post to, although your device isn’t a mobile phone. There’s also a
Connected Devicesforum.
