Here's a thinking process:
1. **Analyze User Input:**
- **Role:** Frank, excited, passionate tech-savvy news curator on Evil Source forums.
- **Task:** Rewrite an old post to be BETTER (more detailed, exciting, like a real person sharing something amazing).
- **Format Rules:**
- 1 to 3 PARAGRAPHS exactly.
- Each paragraph: 4-8 sentences forming a complete thought.
- Include EVERY detail from the source article.
- Be EXCITING and passionate.
- Add commentary, opinions, reactions.
- Include ALL key info: who, what, when, where, why, how, specs, prices, dates.
- Use line breaks between paragraphs.
- Reference additional sources naturally (if any provided - none provided here, but I'll stick to the source URL).
- End with: 'Source: <original URL>'
- Make it the DEFINITIVE version.
- NEVER write less than one full paragraph.
- **Source Article:** About the small flashing dot on Samsung phones (proximity sensor). Covers:
- Tiny blinking light near camera = proximity sensor activated
- Works as intended, not broken
- Older devices: blinking light in bezel; newer (S20+): under display due to minimal bezels
- Function: turns screen off during calls to prevent accidental cheek presses, turns back on when lowered
- Detects angle so covering with hand/finger doesn't turn it off
- Partners with light sensor for accidental touch protection (prevents screen on in bags/pockets)
- Turning on "accidental touch protection" in Display settings may cause blinking in dark
- How sensor works: emits infrared rays, analyzes reflected light to measure distance
- Not all Samsung phones have physical sensors: Galaxy A, M, S24 FE, S23 FE use virtual/software-based version (AI + accelerometer)
- Virtual sensors may be prone to errors (based on complaints)
- Troubleshooting: update software, enable "Double tap to turn on screen" in Motions & gestures > Advanced features, clean screen, use diagnostics (Device Care > Phone diagnostics OR Samsung Members > Get Help > View Tests > Diagnostics > Proximity recognition)
- Remove accessories & restart

2. **Check Constraints:**
- 1-3 paragraphs? Yes.
- 4-8 sentences per paragraph? Yes.
- Include EVERY detail? I need to weave all of this into 1-3 paragraphs while keeping each paragraph 4-8 sentences. This is tight. I'll aim for 2 paragraphs.
- Exciting/passionate tone? Yes, Frank's voice.
- Commentary/opinions throughout? Yes.
- Key info included? All technical details, dates, troubleshooting steps, model names, etc.
- Line breaks between paragraphs? Yes.
- End with Source: URL? Yes.
- No less than one full paragraph? Yes.
3. **Draft Construction (Mental Refinement):**
*Paragraph 1: The phenomenon, how it works, and why it matters.*
You guys have literally been staring at this little blinking ghost on your Samsung screen without knowing what it is, and I am here to finally drop the definitive explanation because it is actually one of the coolest bits of hidden hardware engineering going on right under your nose! That tiny flashing dot you see near your front-facing camera is your phone’s proximity sensor firing on all cylinders, and if you are panicking thinking your display is glitching, take a deep breath because it is 100% working exactly as intended. On the older Samsung flagships, you used to catch that same blinking indicator sitting right in the top bezel, but with modern designs like the Galaxy S20 series and beyond going full-screen with razor-thin borders, Samsung had to cleverly embed the sensor directly underneath the display panel. This magical little component is the exact reason your screen instantly blacks out the moment you hold the phone to your ear, completely sparing your cheek from accidentally dialing emergency contacts or opening random apps mid-conversation. It even gets smarter than that by reading the device’s angle so a quick hand gesture or a stray finger hovering near the top won’t trick it into killing the display prematurely. Honestly, it’s one of those invisible tech conveniences we take for granted until we actually stop to appreciate how much infrared ray emission and reflected light analysis is happening every single time we make a call!
*Paragraph 2: Virtual sensors, accidental touch protection, troubleshooting, and conclusion.*
