Seoul, Dec 6 (IANS): Samsung is reportedly planning to launch three kinds of foldable smartphone models next year.

According to OLED research firm UBI Research, these will likely be called Galaxy Z Flip 2, Galaxy Z Fold 3 and a new Galaxy Z Fold Lite.

All three models will use ultra-thin glass as cover windows.

Galaxy Z Flip 2 will have a 6.7-inch internal screen and a 3-inch external screen.

The internal screen size is the same as the first Galaxy Z Flip launched earlier this year. But the external screen size has increased from the 1.1-inch of the original Flip.

The Samsung Galaxy Z Fold Lite will offer the same display configuration (probably without the under-display camera tech) paired with cheaper internals to achieve a lower price point.

The Z Flip successor will come with the same 6.7-inch foldable panel but a bigger 3-inch external one, compared to the original Z Flip's outer display of just 1.1-inch.

The report also said that the Z Fold3 will have S Pen support.

The company earlier introduced Galaxy Z Fold2 that sports a 6.2-inch cover screen and a 7.6-inch main screen when unfolded.

Galaxy Z Fold2 is Samsung's third foldable smartphone after Galaxy Fold and Galaxy Z Flip.
