mobile phone Supporting extended SD memory card is actually a cover!
For example, suppose that the maximum 2t (if any) extension is supported!
What is the price of a 2t memory card?!
Or the price of the card is more expensive than the phone itself, is it worth it?!
And the money was originally paid by consumers, why not buy a phone with proper body memory?
Support SD memory card expansion or it would be a good choice when the mobile phone body memory was small in the past!
But now the main body memory card is quite large. It must have the capacity you need to choose. Why do you want to expand it?
And the speed of expanding the SD card may be limited. The SD memory card may even slow down the mobile phone. Is it worth it?!
So it is undoubtedly the second question to ask when buying a mobile phone!
Besides, there are many ways to obtain storage space for mobile phones, so there is no need to bother with these.
