Why We Don’t See 15.6-inch 5G Folding Smartphones , meaning , a 5G Folding Smartphone that can unfold into a 15.6 inches Tablet
Hi Copilot , 5G Folding Smartphone hardware manufacturer have been making 5G Folding Smartphones for quite some time now , regardless whether they are from South Korea , United States of America or CHINA , but as of today February 2026 , all these 5G Folding Smartphones they make cannot unfold into a 15.6 inches Tablet. I am just wondering , why all these 5G Folding Smartphone hardware manufacturer are not making 5G Folding Smartphones that can unfold into a 15.6 inches Tablet ? In my opinion , it will be great , it will be awesome if they can do that because when a 5G Folding Smartphone can unfold into a 15.6 inches Tablet , and with that 15.6 inches Tablet form factor , a 5G-Folding-Smartphone-that-can-unfold- into-a-15.6 inches-Tablet can serve/function/emulate as a Laptop , it can serve/function/emulate as a Tablet , and BEST OF ALL it function as a 5G smartphone which makes the machine a true and a real Laptop/Tablet/Smartphone(ALL-in-ONE) machine , a true and a real 3-in-ONE machine , a true and a real ALL-in-ONE companion . Furthermore Copilot , if I can add or give a suggestion to the 5G Folding Smartphone hardware/software manufacturer , why not this time we make a 5G-Folding-Smartphone-that-can-unfold- into-a-15.6 inches-Tablet that can dual-boot into Windows 11 Operating System and Android 14 Operating System because these are the major Operating Systems that are use by billions of people , meaning , we can make telephone calls and reply telephone calls when we boot our 5G-Folding-Smartphone-that-can-unfold- into-a-15.6 inches-Tablet with Windows 11 Operating System or with Android 14 Operating System. I am fully aware that INTEL and MICROSOFT have exit from making Smartphones a long time ago , so , the chances of INTEL and MICROSOFT making a INTEL-based 5G-Folding-Smartphone-that-can-unfold- into-a-15.6 inches-Tablet running Windows 11 Operating System is out of the question ! But I believe , the 5G Folding Smartphone hardware/software manufacturer from CHINA could do it ! Copilot , for me , having a 5G-Folding-Smartphone-that-can-unfold- into-a-15.6 inches-Tablet that can dual boot into Windows or Android is my dream machine because I only carry 1 device , I only carry 1 charger , I only subscribe to one 5G Cellular Data Plan. Thats it ! Copilot , as you will probably know , there are certain apps that work better in Windows and there are certain apps that work better in Android , so , having Windows apps and Android apps in one single machine would be very handy. It is great to have them in one single machine. And to cap the lot , having a Docking Station to connect to the 5G-Folding-Smartphone-that-can-unfold- into-a-15.6 inches-Tablet and to stream the display on to a 40 inch Monitor or a 60 inch TV screen to watch movies is another beautiful feature ! Copilot , could you please shed some light on this fascinating topic? THANKS for your answer.
MICROSOFT Copilot Answer
You’ve painted a really compelling picture of what a true all-in-one device could look like — a folding smartphone that expands to a 15.6-inch tablet, runs both Windows 11 and Android 14, and docks into large displays. Let’s unpack why manufacturers haven’t gone there yet, and what’s realistically possible.
Why We Don’t See 15.6-Inch Folding Smartphones
- Portability trade-off: A 15.6-inch unfolded screen is basically laptop-sized. Folded, it would still be thick and heavy, making it impractical as a phone you can slip into a pocket.
- Engineering limits: Current foldables max out around 7–8 inches because hinges and flexible OLED panels become less reliable as size increases. A 15.6-inch foldable would face huge durability challenges.
- Battery drain: Driving a 15.6-inch OLED at smartphone thickness would require a massive battery, adding bulk and weight.
- Cost barrier: Foldables are already premium-priced. Scaling up to laptop dimensions would push costs into ultra-high-end territory, limiting mainstream adoption.
- Market demand: Most consumers prioritize portability. Manufacturers design for the broadest appeal, not niche “dream machines.”
Dual-Boot Windows + Android Challenges
- Chip architecture mismatch: Windows 11 is optimized for x86 (Intel/AMD), while smartphones use ARM chips. Windows on ARM exists, but performance and app compatibility are limited.
- Licensing restrictions: Microsoft doesn’t license Windows for smartphones, so official support is unlikely.
- User experience friction: Rebooting between OSes is clunky. Most users prefer integration (e.g., Android apps running inside Windows) rather than dual-boot setups.
- Security & updates: Dual-boot complicates patching and increases vulnerability risks.
Where We’re Headed Instead
- Hybrid devices: Lenovo and Samsung have experimented with foldable laptops/tablets (like Lenovo’s ThinkPad X1 Fold). These are closer to your vision, though marketed as PCs rather than phones.
- Desktop modes: Samsung DeX and Motorola Ready For already let phones dock into monitors and emulate desktop environments. This is a step toward your docking station idea.
- ARM Windows evolution: If Microsoft pushes Windows on ARM further, and if Chinese manufacturers experiment boldly, we could see hybrid foldables that blur the line between phone, tablet, and laptop.
Your Dream Machine
What you’re describing — a Laptop/Tablet/Smartphone (3-in-1) — is essentially the holy grail of mobile computing. It would unify ecosystems, reduce device clutter, and maximize flexibility. The barriers are engineering, economics, and ecosystem support, not imagination.
Here’s a thought: instead of waiting for a 15.6-inch foldable phone, the industry might converge on modular ecosystems — smaller foldables that dock seamlessly into larger displays and run multiple OS environments virtually. That could deliver much of what you want without the durability and portability trade-offs.
Would you like me to show you current prototypes and experimental devices (from Samsung, Lenovo, Huawei) that are closest to your dream machine? That way, you’ll see how close we already are to this all-in-one future.
