I'm using an xposed mod to continually be online on WhatsApp, even when my phone's screen if off. Would this thwart such attacks? I mean it would be an anomaly, but other than that I don't know what other information you could get, except the last Online/Offline never changing. It confuses my friends though, who write me more at night times than usually, luckily though I've a DnD mode that saves me from waking up. (confuses gf too)
