recieved my set on wednesday afternoon, do a full charge for 12 hrs, did not encountered any auto shut down, but few things to feedback to AC Ryan, this tab 7 might not be suitable to run on Android 4.0, the tab seem to be slagging when we load the browser, even slower than a smart phone. There are bugs i think you guys need to fix to make the software stable. my screen is not evenly fit into the casing. Look to be your QC is not 100%. Overall i would rate it to be 5/10. I would not recommend to anyone by comparing it to any tab in the PC Show, you are jeopadising your reputation by producing a low standard of tab, not value for money.
I m not sure how many of them had bought this tab 7 but from this forum, there are more negative feedback than positive, Hope AC Ryan can seriously look into the issues and come out with plan to help those with serious auto shut down or any hardware issue.
