When making a smartphone, the focus is almost always on size—either that of the phone as a whole, or that of the screen it possesses.  However, components can only be made so small.  Additionally, the smaller theses parts are, the more fragile they often become.<br />

Another problem is power.  The more equipment a phone uses, the more power it will tend to consume.  When a smartphone is designed to be small, it is difficult to supply it with a battery that will hold enough power for the phone to be practical.  When small, high-voltage batteries are used, they also tend to wear out quickly, requiring more frequent charging.  While motion and inductive charging methods are options being studied,<ref>http://www.nytimes.com/2014/02/03/technology/building-a-better-battery.html</ref> these methods have proven largely ineffective so far.  For these to work, the phone would need to be moved around much more that it ordinarily would be, or a large induction coil must be attached to gather any significant power from the surroundings.  While these strategies may be a part of the future, smartphones currently require a certain irreducible size of chemical battery.

There are a variety of external factors that negatively effect smartphone progress as well.  Terrain is one such factor, since it can interfere with communication.  As a result, the phone's transceiver must be larger and more powerful than a flat landscape would require.<br />

Another much greater external threat is that of malicious people and software.  Now that external software may be installed, and the unrestricted Internet is able to access these phones, there is a significant security risk.  For many people, a smartphone contains all the details of their life.  It must, therefore, be secure.  This consideration has been the driving force behind a myriad of choices in development.  Even with these security considerations, information from smartphones is still often lost through malware, hacking, or physical theft.<br />

Sometimes partly due to certain serious external issues, there are also occasionally detached problems which should have been detected and fixed but were not.<ref>http://money.cnn.com/2015/05/27/technology/iphone-text-message-hack/index.html</ref>  As development continues, the public can only hope that these issues will also be caught, even though the focus is often elsewhere.
