If that's K4 Note, then go to settings > storage > default write disk > set it to memory card.
Make sure to insert a memory card in advance.
But you need alteast class 10 UHS-1 or anything similar memory card for optimum smooth performance. It should support FullHD 1080p video recording.
Memory card is much slower than phone memory, so utilise phone memory more. Keep your daily usage data on phone memory.
There is a limit of expandable storage, so make sure to check official specs to see how much maximum expandable storage it supports. Gsmarena info is mostly wrong about expandable storage limit.
