Unexpected mistakes that damage foldable phones despite 500,000-fold claims

A key mistake when using a foldable phone is closing it with debris trapped between the screens, including dust or sand. The inner display differs from the hard front glass of conventional smartphones and can be damaged by strong pressure or scraping with a fingernail. Protection against solid particles varies by model based on IP ratings. Manufacturers’ fold-cycle figures are based on specific test conditions and do not guarantee real-world lifespan.
