Wear sunscreen to avoid getting burned in the sun!
No two people have the same lines on their fingertips. Using fingerprints we can unblock phones or even find criminals!
Corrected version
Wear sunscreen to avoid getting burned by the sun!
No two people have the same lines on their fingertips. Using fingerprints, we can unlock phones or help catch criminals!
Notes for clarity
- Replace "the sun" with "the sun" after "burned" for natural flow: "burned by the sun".
- Use a comma after introductory phrase: "Using fingerprints, ..."
- Choose gentler phrasing: "unlock phones" instead of "unblock phones" and "help catch criminals" rather than implying absolute outcomes.
