One of the most visible technological trends in recent times are without a shadow of a doubt smartphones with dual screens, which exploit new technologies to bring back into vogue a concept of telephone that was very famous in the first decade of 2000 but completely fell into disuse with the arrival of touch screens and modern smartphones.

The technology underlying dual-screen smartphones (often also used as foldable mini PCs) is very expensive and delicate to produce, this explains why they have not yet caught on and are not yet as widespread as traditional single-screen models such as an iPhone.
Are these phones with dual or folding screens really as useful as they say or is it a simple aesthetic gimmick made only to amaze, but without any real advantage in the basic functions of a smartphone (especially considering the selling price)?
How foldable smartphones work?
Behind a smartphone or a PC with a double screen we find a futuristic technology called POLED, an acronym that identifies Polymer Organic LEDs (or Polymer Organic LEDs).
This screen is composed of organic LED polymers capable of resisting different degrees of bending, without compromising the traditional functioning of the screen: in fact the screen folds and closes without receiving any actual damage, showing the image clearly when completely open.
Thanks to this technology it is possible to create a small smartphone or PC with an internal POLED screen (the largest and most detailed one) and a second traditional monitor, accessible only when it is closed like a book.
Folding smartphone models to try
After having seen the technology behind dual screen devices, in this chapter we will find all the best models that can be purchased on Amazon, for many the best platform on which to purchase also thanks to the effective return policy (something not to be underestimated with a device of this kind, since you may not like it).
Motorola razr 40
The first folding screen phone I recommend trying is the Motorola razr 40, which doesn’t really have a dual screen, but just an external window. The 6.9″ smartphone folds in half leaving a small 1.5-inch external screen that shows the time and notifications. For the rest, we have here a 64+12MP camera and a 32MP Selfie camera, battery 4200 mAh, 33W fast charging, 5G network compatibility, Dual SIM slot and Android 13 operating system.
nubia flip 5G
A different smartphone than usual, with dual screen and foldable is the nubia flip 5G, which has a dual 1.43-inch external OLED screen, 6.9-inch FHD+ internal screen, Qualcomm Snapdragon 7 Gen1 processor, 8 GB RAM, 256 GB internal memory, 50MP AI dual camera, 4310 mAh battery, 33W fast charging, 5G network compatibility, Dual SIM slot and Android 13 operating system.
Samsung Galaxy Z Flip5
Another valid folding smartphone is the Samsung Galaxy Z Flip5, which boasts a 3.4-inch Super AMOLED external display, a 6.7-inch Dynamic AMOLED 2X internal display, 8GB RAM, 256GB internal memory, front camera optimized for selfies, Ultra-Fast charging support, Dual SIM slot, 5G network support and Android 13 operating system.
OPPO Find N2 Flip
A valid folding phone is the OPPO Find N2 Flip, equipped with a 6.8-inch internal display, 3.26-inch AMOLED external display, 120 Hz refresh rate, 8 GB RAM (expandable up to 16 GB), 256 GB internal memory, 50+ 8MP AI dual rear camera, 32MP Selfie front camera, Dual SIM slot, support for 5G networks and Android 13 operating system.
Samsung Galaxy Z Fold5
Samsung’s flagship smartphone in the sector is the Galaxy Z Fold5, which boasts a dual 6.2 inch / 7.6 inch Dynamic AMOLED 2X display, 12GB RAM, 512GB internal memory, triple 50MP rear camera, Ultra-Fast charging support, Dual SIM slot, 5G network support and Android 13 operating system.
HONOR Magic V2 5G
The most expensive foldable smartphone ever is the HONOR Magic V2 5G, equipped with a 7.92-inch foldable OLED internal display, 6.7-inch external display, Snapdragon 8 Gen 2 processor, 16 GB RAM, 512 GB, 5,000mAh battery, Ultra-Fast charging support, Dual SIM slot, 5G network support and Android 13 operating system.
Conclusions
Foldable phones can be considered the trend of the moment, with Samsung leading the way with various models to choose from . The main concern with these phones is the durability of the folding screen: the risk of damage from bending is high, so it is advisable to be ready to replace the glass in case of problems at the folding point of the phone.
