bought my daughter (6 years old) the above for her birthday last month. she loves it EXCEPT i put a 64Gb Sandisk micro SD card in it (the same as her older sisters identical tablet has in) and this one seems to have issues. its NOT the first SD card ive tried in it (but still having the issue) and ive tried the usual remove, wipe with a cloth to clean, reinsert card, make sure it clicks in properly, all to no avail. when the tablet is powered on, it often has a message saying 'SANDISK SD CARD MISSING reinsert SD card' with the little sd card icon in the top left of the screen. also the app icons disappear from the home screen (where my daughter likes them).
now if i go into settings and look up the storage, it shows the card present, working and being used and i can get apps etc to work from there. why does the card keep doing this virtually every time its switched on? every card ive tried does the same. how do i cure the issue? or is it a faulty unit? its on Android version 7.0.
once i go into the memory part of settings, everything reappears and seems fine, till the next time its powered off/restarted.
also the same tablet seems to hang/stall/buffer (whatever you want to call it) when she is watching youtube on it, which is an issue her sister doesnt have, on an identical tablet (5 or 6 months older) even though they are both connected to the same broadband wifi at their home. the older machine has no buffering issues when the newer one does. any ideas?
