Hi Guys,
Looking for a bit of advice here, I have an android tablet (not a branded one) which has ICS installed on it and every time I open Chrome a flashing red frame appears, I have unticked all the boxes in the developer options like other posts have suggested but that hasn't made any difference (I did restart the tablet), I have also tried to reinstall chrome, again made no difference. I have had a look at AVG Anti Virus but can't see anything in the settings which I could change to stop this so would anyone have any ideas on what could be causing it? It only happens when using Chrome.
Any help appreciated.
Thanks in advance
