Lock screen timeout

[Pranav122002]

Earlier (before 3,4 days ) my a52

Lock screen timeout was 10 secs

But its now 30secs 

I tried to change timeout by goodlock lockstar,

It has options of

⑴default ⑵ 15sec ⑶ 30secs

I tried all three but timeout dosnt change even it dosnt change to 15sec 

Its only 30 sec 

And now i noticed that lock screen timeout is taking timeout which is display timeout 

*

I want to set 

Display timeout - 30sec

Lockscreen timeout - 15sec

*

Plz anyone help me
