It's probably far worse with Android users that Google is not disclosing. I'm seriously considering changing to Apple after this. Not that its secure but that they are willing to go to this length to communicate it.
Ironically that may be worse for you. iMessage is probably a critical step in 60% (or more) of these exploits, and the various unicode/pdf etc rendering engines are responsible in many exploits. Android's open-source nature likely means that a lot of these things are found by security researchers first. Don't forget that zerodium still pays more for an android 0-day than an iOS 0-day.
Plus, the huge variability between Samsung/Google/Moto/Huawei etc makes it triply hard for a single exploit to be successful.
