Facebook not compatible on Android 4.3 I was asked to resolve a weird problem. Facebook was crashing on my mom's phone, so I wiped it and tried to install it again. Play store says me that my device is not compatible with this version of the app

The phone is a Huawei Y530-U00 and I have android 4.3

I tried what is being said in the Facebook support: https://www.facebook.com/help/instagram/231705083624002 
but it didn't worked. 

What can I do?
You could try installing an APK manually.


Go to Settings &rarr; Security and enable installation of apps from unknown sources. 
Visit APKMirror and click the blue download button. Once the download finishes, click the notification and install the app.


If that doesn't work, you could try the above process again with Facebook Lite, although it looks significantly worse, and may or may not work properly (possibly depending on the country you're living in).

After you've finished installing APKs, you should disable installing apps from unknown sources. 


Go to Settings &rarr; Security and disable installation of apps from unknown sources -- this is important to do, because else you could be tricked into installing a malicious app.
