I will also include information about older versions and potential risks. The article should be informative, practical, and optimized for the keyword "apk facebook android 5.1". I will now write the article in English, as the user's question is in English. I will structure it with an introduction, sections on why Android 5.1 needs an APK, the official support status, the best APK sources, a step-by-step installation guide, troubleshooting tips, alternatives like Facebook Lite, and a conclusion. I will cite the sources appropriately. you're looking for a solution to a "Your device isn't compatible" error or trying to breathe new life into an old phone, is a common quest for many users.

Sideloading an older APK extends the life of a perfectly functional older device. By downloading the correct version for your API level, you can stay connected with friends and family without needing to purchase a brand-new phone or tablet.

Older APK versions may eventually be locked out as Meta updates its servers. If this happens, try downloading a slightly newer version — but be aware that eventually, no version may work. At that point, switching to Facebook Lite or using Facebook through a mobile browser may be your only options.
