How to set up hotspot on Redmi Note so that it does not turn off?

Question

Android

I have a Redmi Note phone, the first Android phone, before that there were only iPhones.
And now my phone falls asleep in hotspot mode (after about 3-5 minutes after turning off the screen), then the hotspot turns off and the Internet disappears.
And the phone must be poke so that it turns on
Is it a feature of the phone or android?
My screen sleep is set to 30 seconds of inactivity...

Answer 1

Everything was decided by Security - Lock settings - Set - and do not turn off the mobile date when the phone is locked . A
friend suggested to me, there was just not a very obvious transition to settings for me
