How to check that my Phone supports MicroSd Card SDXC UHS1 Bus Speed U30 card or not?
If your phone specification state that it can support sd card &gt;32gb (recent phones have support like 128gb, 512gb, 1tb or 2tb), then it supports SDXC.
Otherwise if it only supports 32gb and below, it only supports SDHC since there are no SDHC cards that has greater than 32gb of storage.
Regardless of the UHS-1 class, your phone can still detect micro SD cards that is SDXC compatible since it only specifies the card speed, not the compatibility. At the moment, no phone supports UHS-2 cards (not to be confused with UHS-1 class 2 or U2) but you can still use it since it is backwards compatible - though, you will not gain the optimal speed of that card.
Hope this helps!
