I have 32gb and 8gb micro sd card. but if can buy to increased GB? DJI have limited GB! for phantom 3

According to the specs:
Supported SD Card Types   Micro SD - Max capacity: 64 GB. Class 10 or UHS-1 rating required

People get dazzled by the (not always true) idea that bigger, faster, more expensive = better
Sometimes good enough is good enough

Using 64 GB cards is not necessarily a good idea.
Do you want to store the work of many flights on one card and keep sending it out and risk losing it all?
Using a number of 16 GB cards is probably a better strategy.

Stick to 16 or 32 the two 64 gig top quality cards I have used both have had problems, waste of money

Your problem was due to the quality of the SD cards, not their capacity.
