One device for everything? Foldable smartphones in everyday work life.

Industry 4.0: from technological trend to practical application. With large displays, foldable smartphones open up new possibilities for planning, documentation, and communication. But what should businesses consider when buying one?

This article is part of the special topic Digital Crafts

Our preview of foldable smartphones (foldables) Craftsmen benefit from two classes of equipment in one: When closed, they function as classic smartphone with front-facing display, unfolded they an almost tablet-sized touch work surface with over 8 inches.

For craft businesses, this means one significant expansion of mobile working opportunitiesBuilding plans can be displayed larger, measurements can be checked more easily, and photos can be edited more conveniently. Applications such as digital construction diaries, project management tools, and documentation software particularly benefit from the larger screen, as multiple apps can be displayed simultaneously. Multitasking allows users, for example, to write emails while plans or photos remain visible.

Added value in everyday work

This combination of mobility and screen size offers a significant advantage in everyday work. tangible added valueThis is how it can be done complex documentation directly on site Perform the process without additional devices such as a tablet or PC. Photos of damage or construction progress can be taken. be conveniently processed and forwardedCustomer communication also benefits: plans or visualizations can be presented directly and in large format to customers.

Another benefit is that Integration of artificial intelligenceFoldable smartphones analyze images, recognize objects, and assist with text creation. They can also automatically transcribe voice recordings and structure notes. For craft businesses, this means less manual rework and more efficient documentation.

Technology that unfolds

However, the biggest advantage of foldables is also a A sensitive weak point: the flexible display, which can be folded along a hinge. This hinge determines the stability and durability of the device. Current models such as the Samsung Galaxy ZFold 7 or Google Pixel 10 Pro Fold They do rely on improved mechanics and more durable materials, nevertheless Is the construction prone to failure?There is always a risk that dust will penetrate the hinge and cause long-term damage – because Protection against fine construction dust (IP6X) is still rare in foldable phones.However, water protection is often included: many devices achieve protection classes such as IPX8 or IPX9, which temporary submersion is possible.

However, even with the Pixel 10 Pro Fold, one of the best-protected foldable devices with an IP68 rating, manufacturer Google offers no permanent guarantee: Water and dust resistance is "not a permanent condition" and can diminish or be completely lost over time due to normal wear and tear, disassembly, or damage. This shows: Despite all the progress, foldable smartphones are (still) not suitable for permanently harsh environments.Furthermore, the flexible internal displays are inherently softer than conventional glass, as they must be able to bend. Therefore, careful handling of sharp tools near the screen is essential..

The situation is significantly better when it comes to the protection of sensitive data: Models officially available for the German market They are based on the Android operating system, which offers extensive security features. This includes encrypted data storage, biometric authentication, and regular security updates. 

However, challenges can arise with devices from Chinese manufacturers.as Oppo, Honor or Xiaomi. Companies should ensure that their data processing and cloud services comply with European data protection requirements.It is crucial to rely on local data storage and data protection-compliant security solutions. Mobile device management (MDM) systems can also help implement security policies and control devices.

Conclusion

The decision to buy a foldable smartphone depends heavily on the intended use. Foldables are not yet suitable as robust companions for harsh construction site conditions due to their lower protection classes.However, those who regularly show plans and presentations, edit photos and documents, or use multiple applications simultaneously in dust-free environments benefit particularly. Businesses should consider whether potential added value justifies the high purchase price.
