5G and foldable phones: have there been any technology trends in the news as much as these two? 

5G promises massive capacity and low latency beyond what 4G can deliver. It brings greater speed (the ability to move more data faster), lower latency (everything’s more responsive), and will increase the maximum number of connected devices at once (a huge boon the mobile operators, and anyone connecting sensors, IoT, and smart devices). It’s a major investment for the mobile ecosystem over the next decade and could have a massive impact on the kinds of mobile apps delivered in the future.
