Urgent warning to iPhone users over troubling 'glitch' that exposes browser history when you hold your device a certain way

An embarrassing glitch has reemerged on iPhone, judging from complaints online -- a bug that dredges up old web searches many would like to keep private. Some Apple users are discovering that their devices are displaying old adult content at unwanted moments, despite their best efforts to clear their browser history, tabs and cookies, even after making sure to view risqué content in'incognito mode' only. 'I have a fairly new iPhone and this is happening,' one Apple fan confessed. 'Old porn vid stuck in Firefox preview mode, only happens in landscape [mode] though.' Another user told horror stories of their iPhone displaying old adult content while'people have been looking over my shoulder as I am showing them something.'
