When using certain mobile devices, you may find that they are not user-friendly. For instance, on some devices, the keyboards may be too small to type or the screen may be too small to capture all the things you need. This means you may need to look for alternative solutions, otherwise your work would be delayed and your level of productivity would be affected in the long run.
Many things can cause interference when using mobile devices. For instance, the network can be affected by the weather or interrupted by a stronger signal around you. In some cases, certain types of buildings limit the flow of network signal while some people use to deliberately prevent network connections around their locations. All these could negatively affect your flow of work.
