How to set up mobile devices with a personalization layer over Android OS

In the case of having to set your app on a mobile device with heavy layers of personalization (Huawei, Xiaomi,etc), there are some parameters you should adjust to have a clean and satisfactory experience.

Keep in mind this explanation is in a general way, each brand has its own UI and settings, after installing our app you must go to SETTINGS → APPS → APPS SETTINGS and then go to Collaborator, once there:

  • On AUTOSTART or AUTOMATIC START set it to enable.

  • On OTHER PERMISSIONS settings you will see different options such as SHOW ON LOCK SCREEN, SHOW POP UP WINDOWS WHILE ON BACKGROUND, VISUALIZATION OF POP UP WINDOWS and PERMANENT NOTIFICATION. You should enable all the options, this will allow the app show notifications of new messages, meetings, incoming calls.

  • On NOTIFICATIONS should be enable SHOW NOTIFICATIONS, NOTIFICATIONS ON THE LOCK SCREEN. Some devices will have a PRIORITY setting inside here, in that case change it to the max priority possible.

  • And the last setting we should change would be the BATTERY SAVING and this should be set to NO RESTRICCTIONS.

All this changes are meant to make this layer of configuration the most similar to a “pure” android device and a fluent Collaborator experience.
