Sources say Sony is developing a Xperia Flip foldable phone with a 7-inch 4K screen
CTOnews.com, July 22, according to Japanese media sumahodigest, Sony is developing a foldable phone internally, which is expected to be called the Xperia Flip when it goes on sale.
CTOnews.com note: the report quoted source @ RGcloudS as saying that the Sony foldable phone will feature a vertical folding design similar to Galaxy Z Flip5, with a 7-inch screen with an aspect ratio of 21:9 and a 4K screen, but there is no more information about the phone.
The Galaxy Z Flip 4's home screen aspect ratio is 22:9, so Sony's Xperia Flip estimate is a bit wider.
