Presently, we have no idea how successful foldable phones are going to be, especially if the cost of them stays in the thousands.

Google also discuss the usual boring bits such as the radius of the curve in the folded part of the display, something that current foldable technology limits. The patent images reveal the device in a partially folded configuration as well as fully folded.

Another design shows a handset that folds down in three sections, with three display surfaces that stack when folded to create one smaller device.

Google's patent application included several sketches of a potential foldable device.

The Z-folding type of design is interesting hasn't yet been seen on any foldable device outside of concepts and patents; Google could potentially be the first to market with such a product, if it were pursuing it. Interestingly, the patent also shows a second foldable design wherein the smartphone folds twice, making a Z-fold.

What do we expect to see in the iPhone 11?


"Like Apple with its iPhones, Google reportedly outsources manufacturing of the Pixel 3 to Foxconn, and both HTC and LG shared manufacturing duties on the Pixel 2 phones", the report said.

The paten doesn't specifically mention anything about this foldable display being for a phone, however.

It's likely that every major phone brand will eventually bring a folding device to market, but Google does have one advantage over the competition. The patent filed by the company indicated it was working on a flip phone.


Foldable smartphones are the flavour of the year for smartphone companies.

The certain specifications of this new super smartphone of the Chinese company are certainly the Qualcomm Snapdragon 855 processor and at least 8 GB of RAM.
