With fall in Internet prices and more accessibility to Internet, the sale of Smartphones has also already increased. However the trend shows that most users of Smartphones whether IT savvy or not is probably not using it the right way. In spite of wide-scale popularity of Cloud-based Picture sharing services (like, Google Photos, Amazon Photos, Facebook, Instagram, etc.) and Video sharing services (like YouTube, Vimeo, Google Photos, Facebook, Instagram, etc.) only a handful of Smartphone users use the services in the most optimum way. Primarily WhatsApp and other messaging services have contributed to the larger problem of excessive data usage.
Instead of sharing Picture Albums, Video Albums and other Pictures/Videos through the popular Cloud-based Picture and Video sharing services, most Smartphone users still continue to forward content through WhatsApp. Smartphone users also don't change their default Camera settings to reduce the resolution. My experience says that a minimal 3 - 5 Megapixel still Photo and an HD 30 fps video is more than sufficient to watch on Phones, Tabs and large screens at Home/Office. Higher Picture resolution is only required if you really want to print a large Picture (like a Banner). This not only leads to a lot of spamming but increases the Bandwidth requirements and the Storage requirements of your Smartphone.
A 16 GB Smartphone which was more than sufficient for regular use a few years ago is no more sufficient and most users right now seek for 64 GB to 128 GB Storage on Phone and a 4G / 20 Mbps Broadband connection to have a smooth viewing experience. Its still not too late. A simple change in your lazy habits of blind Media forwarding can make a lot of difference.
