I have a Samsung A20 that will not rcognize and micro SD card that I try to use. I have used in my previous S7. Am able to format on S7, but not on A20. Cards have all been checked on PC and S7 to ensure they are not damaged.
If the different SD cards are recognized on a Samsung S7 and on the PC, I'm afraid it's due to a defective card reader on the a20. In that case, you could contact the seller if there is warranty.
I was afraid of that. Not sure of complexity of this kind of repair, but would it be worth paying to get fixed or am i better off just getting a new/replacement phone ?
Since I'm not sure how much it will cost to replace or repair the SD slot, I can't comment on that, but I think it's more worth it to buy a replacement phone.
