How secure is Google Android compared to other operating systems?

Answers

Android security is a mixed bag, tbh. It's gotten way better, but iOS still generally has the edge due to its stricter control. But hey, Android gives you way more customization, so it's a tradeoff.

From a purely technical perspective, Android's security model, while robust, is inherently more complex than iOS's due to the significant fragmentation of the Android ecosystem. The diverse hardware and software configurations across Android devices create a multitude of potential attack vectors, whereas the tightly controlled iOS environment reduces this variability, creating a more predictable and, consequently, securable platform. However, this should not be interpreted as a conclusive statement on the superiority of one over the other. Both platforms benefit from continuous improvement in their security posture and ongoing advancements in threat detection and mitigation.

Can I track an iPhone's location from my Android phone?

Answers

No. You need the iPhone user's permission.

From a technical standpoint, directly tracking an iPhone's location from an Android device without the iPhone owner's explicit consent is infeasible due to Apple's stringent privacy protocols and built-in security measures. The operating system itself is designed to prevent such actions. Any suggestion that this is possible, outside of features like 'Find My' with proper consent and setup, is fundamentally inaccurate. The key lies in the user's settings and choices within the Apple ecosystem; there is no technological workaround for this.
