2. Install Facebook Lite
Wait, did you even know Facebook have another app? Hell no, right? Anyway, now you know. Since we all know how much data and RAM the regular Facebook app consumes, that’s why installing the Facebook lite version is the answer to your problem.￼
As much as I love the Facebook app, I despise the fact that it’s one the best RAM killers on smartphones, Facebook lite on the other hand, might not be the best appearance wise, but it’s pretty satisfactory. It’s a really good alternative to the main app, saves a lot of data, require less storage space for install, perfect for 2G network and reduces RAM usage because of its lite appearance. You should give it a try.
