I tried just copy pasting but after that i had gray icons, clicking them said apps not found. Under settings/apps i couldnt find the apps. So i just plugged in the old card and moved apps to internal storage, plugged in a new one and moved them to sd card. Took just few minutes.
Testing the speed of sd card is funny, always get about 60mb/s write, read is sometimes 60mb/s, sometimes 120mb/s. Using sd card testing apps. Sd card is exfat and half full.
My phone for some reason gets incredibly slow when i have only 2/16gb internal free. Which happens fast cause unmovable youtube and chrome bloat from 150mb to 600-800mb. When i manualy clear cache on them, the phone flies. I have like 1 gig of important apps on internal storage, banking apps. I removed everything else i could to sd card, yet i only have like 4.5gb free on internal. Wish i could free more. Unrooted phone cause i cant root, otherwise banking apps wont work. Its cheap old phone but seeing how it flies after cache delete makes me sad - its still perfectly usable when i disable all nonsense. Wish i could move youtube and chrome to external and convince it to remain on a diet. Also freeing a gig or 2 would also give me some headroom. But not sure what else i could do. 12 gig on android 8.0.0 sound a little much. And this internal storage slows down when full. Dont think defrag would help with non mechanical flash disk or sd card
