body: I have a question regarding the use of Android.
  
  
  We want to sell devices, that are equipped with a modified Android-System. 
  
  
  * Some things are restricted
  * Some apps are preinstalled
  * We use the company logo when booting the system.
  
  
  Is there something we need to consider in this case?
