❓ Frequently Asked Questions (FAQ)
Q1: Will enabling all these settings slow down my Samsung phone?
A: No. These settings either optimize performance or add useful features without slowing down your phone. RAM Plus and Auto Optimization actually improve performance.
Q2: Is Protect Battery really worth it? I lose 15% capacity.
A: Yes! 85% is enough for most people's daily use. In exchange, your battery lasts 3-4 years instead of 2 years. Over phone's lifetime, this saves money and maintains performance.
Q3: Which settings give the biggest battery improvement?
A: Top 3 for battery life:
- Protect Battery (85% charge limit)

A: Absolutely! All settings can be reversed. Simply go back to the same menu and disable them. Nothing is permanent.
Q6: How much RAM Plus should I enable on 6GB RAM phone?
A: 4GB is optimal. It gives noticeable multitasking improvement without slowing storage. More than 4GB has diminishing returns.

A: Secure Folder uses Samsung Knox, military-grade encryption certified for government use. It's extremely secure. Even Samsung can't access it without your password.
Q8: Does Link to Windows work with Mac or only Windows PC?
A: Only Windows (officially). Mac users can try third-party apps like "Your Phone" alternatives, but Link to Windows is Windows-only.
