Facebook is the largest social media platform. Its still growing with tons of users per day. But the mobile app of Facebook is nowadays is just a ballon which is getting bigger and bigger day by day.
Concept: It is very nice concept of Facebook to provide access to social media via smartphone. It brings the world of Facebook at the fingertips of the people.
Layout and design: laptop and design of this app is getting very complicated and messy day by day. They are adding new features and messing them in a single app. This makes them to bring a new update frequently and it frustating for users. This app takes too much of RAM and drains the battery of device. Also it consumes the large amount of data.
Features and Functions: features and functions in this app are good but it makes the app messy as they are packed in a single app. App many time force stops and the phone misbehaves.
Usefulness: This app is very useful but only if you have large amount of RAM on your device, if your device is old then this app may hang up your device.
For those who have old phones this app is like a heavy basket put on the head of the phone. These things make this app as a bulky app. Hope Facebook will resolve it in coming updates. Otherwise this app is good.
