Foldable iPhone faces engineering challenges, Apple shares plunge over 4% in a single day

```

The development of Apple’s foldable iPhone has hit another setback, causing a noticeable decline in its share price.

According to Nikkei Asia, Apple’s foldable iPhone is currently facing technical obstacles during the engineering testing phase. The complexity of the related engineering issues and the time needed for their resolution have both exceeded expectations, so the first batch of shipments may be delayed by several months.

The report quoted a source familiar with the matter as saying: "Indeed, more problems have arisen during the early trial production phase than anticipated, and additional time is needed to resolve these problems and make necessary adjustments."

After the announcement, Apple’s share price dropped 4.3% on Tuesday.

This news had a direct impact on market sentiment. Apple’s share price had previously risen by a cumulative 5% over four consecutive trading days, and this drop wiped out all recent gains.

Previous media reports stated that the foldable iPhone, when unfolded, would use an iPad-like operating interface, focusing on providing a large-screen productivity experience. This product is regarded as one of Apple’s most notable hardware innovations in recent years, and the market is highly sensitive to any changes in its mass production schedule.
