Each time I insert a TF card I find it works for a while and then all data is lost.
Recovery programs fail to retrieve any files or photo's as though they were never on the card.
My other problem is that I cannot download apps and am constantly asked to delete other essentials.
I'm currently trying to set up a Fitpro smart wristband to monitor heartbeat, blood pressure etc but cannot do this.
TF cards I've used have been generic and also San Disc.
Phone in use is Wieppo S5 bought on Amazon with Android 7 Nougat.
