(Pocket-lint) - Samsung's Galaxy Z Fold 3 is a great folding phone, but with the folding phone market really starting to pick up, all eyes have turned to what Samsung will improve on and offer in its next generation of its Z series.

This is everything we have heard about the Galaxy Z Fold 4, including when it might be released, what it might offer and how it might improve on the Galaxy Z Fold 3

Samsung Galaxy Z Fold 4 release date and price

  • September 2022
  • Around £1599/$1799?

The Samsung Galaxy Z Fold 4 is expected to be released sometime in August 2022 or September 2022. It's been claimed there will be an announcement on 10 August with availability starting 26 August, but that's unconfirmed by Samsung for now.

The Galaxy Z Fold 2 was released in September 2021 and the Galaxy Z Fold was made available in September 2019 so if the rumours are accurate, the Galaxy Z Fold 4 could arrive a little earlier than its predecessors and in the place of the Note series.

In the past, the Galaxy Note series had an August release slot, but we haven't had a Note since 2020, with the Galaxy S22 Ultra essentially replacing this line, leaving the launch slot for the Z series.

In terms of price, the Galaxy Z Fold 3 starts at £1599 in the UK and $1799 in the US. We'd expect the Galaxy Z Fold 4 to be around the same. There has been a rumour to suggest it might be cheaper, though it's not detailed by how much.

Design

  • Similar to Z Fold 3
  • IPX8 rated
  • Built-in S Pen?

It's been claimed so far that the Samsung Galaxy Z Fold 4 will feature a similar design to its predecessor - though a little smaller and slimmer - and instead focus on durability. If this is the case, we can expect a book-style design again with a triple rear camera housing on the rear. Based on some early renders, it looks like the camera lenses could sit on their own rather than within a housing for the Z Fold 4.

There has been some talk of more than one under-display camera this time around, presumably one on the external display to go with the one on the internal display, and there is also talk of a built-in S Pen, like the Samsung Galaxy S22 Ultra offers. That said, rumours have also said no built-in S Pen for this device so this feature is still in question for now. Either way, it will no doubt be compatible with an S Pen.

An under-display fingerprint sensor was also mentioned for the Galaxy Z Fold 4 initially, though it has since been claimed the device will stick to a physical fingerprint sensor on the side like the Z Fold 3.

The Galaxy Z Fold 3 offers IPX8 waterproofing, as well as a tougher frame compared to its predecessor so we'd expect the Z Fold 4 to retain that IP rating, if not improve it.

Display

  • 6.19-inch external
  • 7.56-inch internal
  • 120Hz refresh rate

Reports suggest the Samsung Galaxy Z Fold 4 will come with similar size displays to the Galaxy Z Fold 3. It's been claimed the external display will be 6.19-inches, while the internal display will open up to 7.56-inches. There's still expected to be a crease in the display, though it will apparently look slightly better than the Z Fold 3.

It's also said the display ratios will adjust slighty too, becoming shorter and wider, which will mean a squarer internal display if these rumours are accurate.

It's expected that both the internal and external display will offer a 120Hz refresh rate like the Z Fold 3 did, and it is also expected that HDR10+ will be supported. The inner display is said to be an QXGA+ AMOLED panel, while the outer display is said to be an HD+ AMOLED panel.

Rumours have also said Samsung will offer a tougher and improved UTG (ultra-thin glass) for the Galaxy Z Fold 4. 

Hardware and specs

  • Snapdragon 8 Gen 1?
  • Improved battery

In terms of hardware, it's been claimed the Samsung Galaxy Z Fold 4 will run on the Qualcomm Snapdragon 8 Gen 1+ chipset and there will be a 12GB RAM with 256GB storage variant, and a 16GB RAM and 512GB variant. There's also been the suggestions of a 1TB option.

Rumours around the battery have been mixed. It has been said we can expect a 10 to 20 per cent battery improvement for the new device. Initial rumours claimed the battery would be a combined battery capacity of 4270mAh, with a 2002mAh battery and a 2268mAh battery. More recent rumours have said there would be a 4400mAh battery.

The Z Fold 4 will no doubt offer flagship specifications - even if they differ slightly fro the rumours. Either way, we'd expect to see 5G capabilities.

Cameras

  • Triple rear
  • 3x zoom

It's been claimed the Samsung Galaxy Z Fold 4 will have a similar rear camera loadout to the Galaxy S22.

Rumours suggest the zoom capabilities would increase from 2x on the Z Fold 3 to 3x on the 2022 device, though the resolution could drop from 12-megapixels to 10-megapixels, which would match the S22.

The Samsung Galaxy S22 has a triple rear camera, made up of a 50-megapixel main sensor with f/1.8 aperture and OIS, plus a 12-megapixel ultra wide sensor with an f/2.2 aperture and a 10-megapixel telephoto lens with f/2.4 aperture. The telephoto lens offers 3x optical zoom.

There's also been the suggestion that the Galaxy Z Fold 4 will have a 50-megapixel main sensor, 12-megapixel ultra-wide sensor and a 12-megapixel telephoto sensor with 3x zoom. That same link suggested the 3x zoom would be better than the Galaxy S22 Ultra. On the front, it's said there will be a 10-megapixel snapper, while the inside front camera is said to be an under-display camera and offer a 16-megapixels resolution.
