I've recently bought a Telechips X5 7" Tablet from Amazon.co.uk. Latest 1080P 2GB X5A 7" Android 2.1 Tablet PC with Telechip 8902 processor and HDMI out: Amazon.co.uk: Computers & Accessories After a number of initial teething problems I'm left with one major problem I can't figure out for myself so I'd appreciate some help. Every time I insert an SD card the whole tablet hangs. I've tried three different sized cards by two different manufacturers all with the same result. The only way to get it working again is to reset. I hope someone out there can help me resolve this issue.
