Closes #327

What has been done to verify that this works as intended?

• Samsung j8(Android version 9) - ok
• oneplus 6(android 10) -ok
• vivo y55s(android 6)- Not shown (working fine everything no problem)

2. Checked whether every activity is working fine or not

How does this change affect users? Describe intentional changes to behavior and behavior that could have accidentally been affected by code changes. In other words, what are the regression risks?
