Android Samsung TAB e auto turn on Hotspot? Is there a way to automatically turn on the hotspot when my samsung tab e starts up?
You can use Tasker (7 day trial available) to accomplish this or Macrodroid (free up to 5 macros)

Objective: Auto switch-on  mobile hotspot after boot

Profile (or Trigger)

Create a Profile which allows triggering of the Task after boot:


Go to Profiles Tab and click  "+"
Event  → System  → Device Boot
Tap back to exit from this window


Task

You will notice as soon as you exit, you will be prompted to link this Profile to a Task;


Scroll all the way up the Task list select "New Task + "
You can name this Task AutoTethering or anything.
Click "+" to add new Action
Net  → WiFi Tether (Set On)
Press back the way all back until you exit Tasker (your profile is now saved and is ready for execution)


Extras: Give Tasker more priority (allow auto-start for Tasker, exclude from battery optimisations, task killers etc)

Explanation: Soon after boot, the first action  turns on Wi-Fi tethering (note:  Tasker already has a built in WiFi Tether variable which is capable of handling tethering state)

This should work. (tested)
