Xperia XZ1 Compact, android 8.0. Solid Explorer cant write my Samsung 128 micro SD. Any other app like Total Commander, Root Explorer or Mixplorer can. Even built in Android file manager can. I already give permission to write and read files at first start up. Interesting fact is that I can see (just that, not write) my SD card if I go to Root / Storage / micros. But I don't see my micro SD card as a normale storage at the left main menu
