Just a quick promotion of a webinar that aims to teach people how to tell if Pegasus or similar software has been infiltrated onto their device. I just don't use my phone for anything but text and phone calls. I don't take my phone out of the home. This makes my device almost irrelevant to spooks, doesn't leave any data trail across the web, and costs less because I can use the lowest quality, and cost, device available on the market. But that's probably not how you secure your devices from creepy stalkers that want to copyright the dick pics they stole off your device and add them to their massive, personal hoard of >16M dick pics they have at home for their viewing pleasure.
Whatever uses you put your device to increase the attack surface you present to the world. The more you rely on your phone, the more devastated you will be when hackers gain control of it, it's bricked, stolen, or otherwise used by malevolent parties to do you harm. Take Back Our Tech is a movement, as well as a company that wants to help you help yourself, and that's what the Webinar referred to in the title of the OP is intended to do. TBOT wants to teach you how to tell if your phone has been infiltrated by malware that could present all kinds of risks (besides stealing your dick pics), or if there's just some update, or a bug. The link above is <2 minutes of video explaining, and you should take the time to hear them out.
I hope ya'll that put your phones in harms way take the time to tell when they've been harmed, so you don't get hurt more than necessary when they come for you.
