Zenfone 3 Max 5.2 with little space no Android 7

I wanted to suggest that, in the next update, add the option to format the Micro SD card as internal storage for Zenfone 3 Max 5.2 with 16Gb, because Android 7 uses a lot of space and ends up leaving little space, I hope you Read this and think about the idea.

I look forward to your response.
