There are no explosives in a phone though. Lithium batteries might burn when short circuited... however, this requires physically damaging the battery, or shorting the circuitry. This requires some seriously silly hardware vulnerabilities (lithium cell protection is typically implemented in dedicated silicon), not simply a software vulnerability. And if you could successfully perform an exploit like this, you would probably drop the phone before it hurt you.
At best id be blind and unable to use my hands. I don’t give a stuff about my bank account compared with that.
