Video - how to fix please insert micro-sd tf card
If it is an old tf card that was told 'please insert tf card', then you may need a computer to get it fixed in Windows 10/8/7 or Vista/XP.
Connect your tf card to a computer that installed Windows OS, and then open disk management by right click your computer -> Manage -> Disk Management
And then right click your tf card in disk management -> Delete volume; And then right click the empty drive -> Format, and then your tf card can be formatted to FAT32/EXFAT/NTFS per your need.
If you do not know which one(exfat, fat32, ntfs) to format, you may try fat32 at first, if it did not work for you, try exfat, or ntfs later. And reinsert your tf card back to your phone/camera/recorder.
