Hey there. I am a mom whom ovbviouly does not know crap about computers or tablets. but TODAY after owning my ACER tablet. i noticed when i went into setting to see how my memory was going i saw that only my internal memory was being used. I bought it in October and a week later decided I would add a sd card to up my memory so I could put all my music on it and be able to put a movie or two along with apps. ANYWAY i looked and saw that no SD card was being used it said "mount sd card" so i fiddled with it down loaded astro used my computer to make sure it was using the correct format. Long story short it isn't reading any sd card. SOOOOOO. Is there a quick fix or do I have to send it back to the company. sad part I have to be at a hospital for many many days going through tests biopsies and treatment with my mom for weeks. I need my tablet so i am PLEADING for any advise that could work for me. I did also do a factory reset as well. PLEASE SOMEONE HELP IF YOU CAN..... GOD BLESS.
