Let's think about it this way for a second
Pay close attention to app permissions at install/first-open time — if a flashlight app is asking for access to your contact list and location, that should raise a red flag. Only install apps from the official app store (Google Play, App Store) — sideloading (downloading an APK file directly) massively increases malware risk. Without a screen lock (PIN, fingerprint, face), losing your phone means anyone can open it and see all your data.
Let's connect this to a real-world scenario
With 'Find My Device' (Android/iOS) turned on, if your phone goes missing you can remotely locate it, lock it, or wipe it (erase all data) — a last-resort protection. Public charging station USB ports (airports, cafés) can be used for a data-stealing attack called 'juice jacking', so it's safer to charge via a wall outlet (power only) instead.
Let's look at it together

Go into your phone's app permission list and find (and fix) any apps with unnecessary permissions.
A quick word of caution
Rooting or jailbreaking a phone can disable some of its built-in security protections — don't root or jailbreak your phone unless you have a solid reason to.
