I Used a Foldable Phone for a Month. The Crease Was Not the Problem.

Before I bought the Find N6, I never used screen protectors. My previous phone lasted two years, and its screen was covered in fingerprints and fine scratches, but I never bothered. A foldable was different. On the first day I got it, I went downstairs to have an inner-screen protector applied. The technician said while working that this film was hard to apply. There was a crease in the middle, and he had to push it out slowly with a squeegee. I stood there watching. He pushed four times, and there was still an extremely thin line of air bubbles down the middle. He said it was normal. All foldables were like that.

That night I lay in bed with the lights off, tilting the inner screen to look for the crease. From the front there was nothing. Tilt it slightly, and there was a shallow groove in the middle of the screen, as if someone had gently drawn a fingernail across soft clay. I turned on the bedside lamp, and it disappeared again. Turn off the light, and it came back. I turned the light on and off three times. The last time, my wife said, “What are you doing?” I said, “Nothing. Looking at the screen.” She said I was crazy.

The next day I used it all day and didn’t think about the crease once. Reading documents, replying to messages, unfolding it at lunch to watch a video. From the front, the crease almost didn’t exist. Only when my finger passed over the middle of the screen could I feel a slight dip, a resistance, like touching a very thin thread under a tablecloth.

What made me stop was cleaning. The inner screen had fingerprints on it. I wiped it with a glasses cloth, then held it up to the light. The oily smudge was still there, smeared into a small patch at the edges. I wiped again, a little harder. The smudge spread but didn’t disappear. I gently scraped the screen surface with my fingernail and felt a fine, frosted resistance. Not the slickness of glass. I looked closer. The screen surface did have an extremely fine texture, barely visible to the eye but noticeable to a fingernail. Oil had gotten into those textures, and a dry cloth couldn’t get it out.

I looked it up. The nano-texture was meant to scatter light and soften the crease. The crease softened. The tradeoff was a surface that no longer felt like smooth glass. I took a microfiber cloth, put a little cleaning solution on it, and wiped gently twice. Only then did the oily smudge come off. That night I turned the light on and off again. The crease was still there, but the smudge was gone. I sat on the edge of the bed and wiped the screen three times before I remembered that all I’d meant to do was reply to one message.

Later I went to an Apple store to try the folding demo unit I’d heard about. There was one on display. I picked it up and folded it twice. The hinge damping was different from the Find N6. Tighter, and it would stop halfway. I unfolded the inner screen and looked. From the front I could barely see a crease. It looked cleaner than mine. But when I ran my finger across the middle, fingerprints stayed on the screen. I wiped them with my sleeve, and they wouldn’t come off. An employee handed me a cloth and said it was best to use a dedicated cleaning solution. I wiped twice. The smudge faded a little but was still there. I put the demo unit back without saying anything.

On the way home I kept thinking about it. The crease wasn’t obvious, but the screen was hard to wipe clean. My Find N6 had a slightly more visible crease, but at least I could get it clean with three wipes. The surface texture on Apple’s demo unit was finer. Once oil got in, it was harder to get out. The microscopic bumps that Media Storm saw with an atomic force microscope? I could feel those bumps in the store through my sleeve.

That night I unfolded the Find N6 and left it on the table without turning on the light. The groove in the middle of the screen was almost invisible in the dim light. I ran my hand over it. I could still feel it. Then I folded it, stuffed it into my pocket, and went to the kitchen to pour a glass of water. When I came back, I forgot it was still on the table. I picked it up and replied to a message without folding it, typing one-handed. Only after I finished typing did I realize I hadn’t been paying attention to the crease.

I’ve used it for over a month now, folding it about twenty times a day. At 3,000 folds, that’s about five months. But I don’t think about that number much anymore. The crease is still there, visible only from certain angles, with a little resistance when my finger passes over it. The oily smudge comes off after three wipes. Every now and then I still think about Apple’s demo unit. Its crease was fainter, but the screen was harder to clean. The interaction was smoother. The system-level stuff is something the Find N6 can’t match. But with a first-generation product, there are always compromises in the hardware. The bubble line in the middle of the inner-screen film I’d applied was still there. I hadn’t replaced it. The technician was right. All foldables are like that.

Yesterday on the subway, I unfolded it one-handed to look at a map, then folded it and stuffed it into my pocket when I reached my stop. As I folded it, the hinge made a soft click. The person next to me glanced over. I didn’t feel anything. On my way out of the station, I touched my pocket. The phone was folded, screen facing inward. I didn’t open it again to check the crease.
