Hi nairalanders, plz. I use an HTC android phone and recently started observing that some videos/songs on the memory card, do not appear on the phone's music/video player respectively. What happened was, I have a Bluetooth mini speaker and so normally play music on the speaker via the my phone Bluetooth but, when the phone ba3 is low, I simply remove the m.card and insert it directly into the mini speaker. It was on one of this occasions, after restoring the m.card back into the phone that I observed that my songs/videos non complete again o.... But, when I access the m.card content via the file manager, I just see all of them for there dey chill dey look me.
