OPPO U71T mobile phone memory card can't be read. What's the matter?

1. The memory card of the mobile phone cannot be read because of the broken mobile phone card or poor contact.

Solution:

If it is poor contact, this is a good problem to solve. Take out the card, erase the gold finger of the memory card with an eraser, remove the oxide layer on it, and then put it into the mobile phone to try. If it doesn't work, pry the antenna inside the memory card holder higher, or apply a layer of glue on the back of the memory card to increase its thickness. Insert the card into the card reader (make sure the card reader is good), and then insert the card reader into the computer to see if the data in the card can be read. If the computer can read the card, it means there is nothing wrong with the card. Maybe there is something wrong with the slot of the mobile phone card. Try inserting a normal card again. If other cards can't be read, the slot of the mobile phone card is broken. Please ask someone to repair it.

2. The memory card of the mobile phone caused by poisoning cannot be read.

Solution: There are many such cases, and poisoning can also lead to the problem that the memory card cannot be formatted, which is generally difficult to repair. If the virus causes the mobile phone memory card to be unreadable, it is necessary to format the memory card. (Sometimes there will be problems that the memory card cannot be formatted and the memory card cannot be formatted.) Generally, the formatted memory card can fix the problem. Memory cards that can't be formatted are not easy to repair, and of course they can also be repaired with the help of memory card repair software. If there is important data in it, you have to use the data recovery tool to recover the data inside. Be careful not to write data into the memory card after formatting, which will cause incomplete recovery files.
