Browser Used
  • Recent addition of Raspberry Pi comes with a Chromium browser which is quick and robust than the browser available in its predecessors, but still it gets stuck when it comes to opening number of heavy duty sites, however, YouTube video buffering is too quick that you don’t need to wait too long before video comes into play.
  • Opening number of sites at once can take more time than you anticipate, which ultimately hangs the device, causing the device memory to freeze or stuck.
  • Although, experts are in constant struggle to add more advanced features with every new addition, still Pi 3 doesn’t support number of advanced applications.
