Samsung’s three mains objectives behind growing the brand new Galaxy Z Fold 3 and Galaxy Z Flip 3 foldable smartphones had been to supply significant experiences, sturdiness and affordable pricing, an organization government mentioned.
Samsung Cellular government vice chairman and head of flagship product R&D workforce Gained-Joon Choi advised ZDNet that the corporate believes these three components for its newest units shall be what takes foldable smartphones mainstream.
“We’re assured that the foldable smartphone class will develop. And that progress must be sustainable,” Choi mentioned. “So for us, the large query was how can we provide a brand new worth that’s price what our prospects are paying for these units. That can’t be the novelty issue of folding alone.”
In keeping with the chief, Samsung carried out plenty of shopper analysis previous to and through the improvement of the Z Fold 3 and Z Flip 3, and one vital a part of that was discovering out prospects’ willingness to repurchase a foldable smartphone. Most of the new capabilities and experiences on the units had been a direct results of that analysis, Choi mentioned.
ECOSYSTEM AND S PEN
In keeping with Choi, the Z Fold 3 and Z Flip 3 usually are not about displaying off the corporate’s folding expertise, however the expertise they provide. Samsung collaborated with Google to combine the Android working system into the folding units. It additionally reached out to lots of of third-party app builders to persuade them to be a part of the foldable ecosystem, the EVP mentioned.
Choi additionally talked up Samsung’s Good Lock function — an app that enables customisation throughout themes and person interface for Samsung units — and the way it may be utilized in foldable units to spice up person expertise. The app can be utilized to customize sure apps comparable to Instagram to scale back black areas and combine higher with the folding display, he mentioned.
“We expect we have reached a sure completeness in terms of the folding kind issue expertise. We have mirrored on buyer suggestions loads. However we won’t do it alone. We’d like third-party builders to affix us in growing apps that help flex mode, massive screens, and multi-window setups,” Choi mentioned.
Including in S Pen help for the Z Fold 3 was additionally a part of Samsung’s efforts to supply a significant expertise on the gadget, he mentioned, however that was extraordinarily troublesome.
“There have been occasions we needed to surrender on the function. The expertise to help the stylus for the foldable kind issue wasn’t executed in a 12 months, nevertheless it was years within the making.”
The rectangle-shaped digitiser sheet beneath the show, which finds the placement of the pen’s tip by resonance sensing, is made with arduous materials and isn’t versatile just like the show panel. Samsung initially meant to have the digitiser as one sheet beneath the panel, however after repeated failures to make this purposeful, the corporate got here up with the easy answer of slicing it in half and placing one digitiser on both sides of the fold, Choi mentioned.
“We made certain the 2 digitisers shared their indicators and likewise utilized our writing sample prediction algorithm to make the stylus work between the hole.”
For the tip of the S Pen, Samsung additionally collected information on how a lot drive may very well be generated when prospects pressed it strongly in opposition to the show panel to guard them for scratches.
On whether or not the corporate considered housing the S Pen contained in the Z Fold 3 because it did for the Word collection, the chief mentioned the corporate thought of plenty of choices on find out how to incorporate the stylus for its folding units.
When deciding to not home the S Pen within the Z Fold 3, Choi mentioned the brand new foldable is 6.3mm in thickness when unfolded, thinner than the Word collection’ round 7mm, which meant if the pen was housed inside, it will be too skinny.
“If the pen is simply too skinny, it ruins the sensation of writing. We thought loads about advantages and trade-offs when it got here to how we needed to current the S Pen on the Z Fold 3.”
Nevertheless, Choi did acknowledge the advantages of housing the stylus inside a cellphone and mentioned the corporate would proceed to “assume exterior the field” to give you the very best options for the S Pen.
IMPROVING HINGE DURABILITY
In keeping with the chief, sturdiness was one of many prime priorities for the Z Fold 3 and Z Flip 3 as shopper suggestions confirmed that one in all their largest issues was across the sturdiness of the units.
“The show panel and the hinge are a very powerful components by way of sturdiness,” Choi mentioned. “For the show panel, we noticed all of the defects comparable to scratches which have occurred within the prior iterations. These show panels have very complicated layers and now we have to make these layers versatile and strong on the identical time.
“We mulled over the proper thickness of those layers, the supplies we use for them, adhesives, and the quilt movie.”
For the hinge, a very powerful element in each units for reaching the IPX8 water resistance ranking, Samsung targeted on making the construction easier. The Z Fold 2’s hinge had over 100 parts however for its successor, this quantity has been halved, Choi mentioned.
“We tried to scale back the method steps to fabricate the Z Fold 3 and Z Flip 3 in addition to their parts throughout. We additionally optimised the supplies in order that they’re robust, water-resistant, and cost-competitive.”
This innovation in design and supplies additionally allowed Samsung to realize a cheaper price tag for the units to make mass producing them easier, the EVP added.
NEW UNDER-DISPLAY CAMERA MIXES SOFTWARE WITH HARDWARE
The screens of the Z Fold 3 and Z Flip 3 each mark the primary time a foldable has supported a 120Hz refresh charge, and the Z Fold 3 is the primary time Samsung has carried out an under-display digicam. Samsung touted each options closely in its Unpacked occasion, however Choi famous that the event processes for each options weren’t with out hurdles.
“A 120Hz refresh charge on the foldable screens was a problem due to their greater energy consumption because the screens are usually bigger than standard telephones. Scrolling by them additionally must really feel pure. Now we have tons of expertise in software program tuning optimisation, which allowed us to over this problem,” Choi defined when touting the brand new function.
Whereas power effectivity was the problem for upping refresh charges, the under-display digicam posed an issue for Samsung relating to find out how to make the picture sensor correctly take in mild, which meant the corporate wanted to enrich the brand new {hardware} with software program to supply photos it was proud of.
Not like standard entrance cameras that do not have a panel masking them, under-display cameras are unable to totally take in mild resulting from being blocked by a show.
“Since now there’s a show panel above the digicam, we needed to discover methods to minimise the lack of mild when it passes by the show panel to achieve the picture sensor,” Choi mentioned.
“The important thing to reaching the under-display digicam function was the picture restoration algorithm we used. The software program will work to recuperate the picture or video to their full content material if it detect shortcomings.”
In speaking concerning the new under-display tech, Choi additionally mentioned the Z Fold 3 complemented the opposite digicam choices obtainable on the gadget, comparable to utilizing the primary digicam to take selfies in flex mode.

The Z Fold 3 and Z Flip 3 every sport a triple 12MP digicam and double 12MP digicam, respectively, as their primary shooters.
Strictly by way of pixels, that is behind the specs of cameras put in standard flagship smartphones. The Galaxy S21 Extremely, for instance, packs a 108MP primary shooter.
On whether or not Samsung plans to spice up the {hardware} specs of the cameras for foldables, Choi mentioned: “What number of cameras there are and what pixels they’ve is after all vital, however we felt the general expertise of how the cameras are used is extra vital. So we’re specializing in placing on our sources in digicam software program proper now.”
Addressing the 2 kind components introduced within the Z Fold 3 and Z Flip 3, the EVP mentioned Samsung remains to be persevering with to overview different kind components however will solely launch them in the event that they add one thing new and helpful.
“The vital questions is whether or not a brand new kind issue can present an expertise that wasn’t obtainable earlier than. We do really feel nonetheless that down the highway there shall be a time once we can introduce a very new expertise within the foldable area,” he added.
