Last month dispay flickering and blank screen issue occured, contacted Mi service center and display component was changed after one week.
After 12 days issue repeated and contacted Mi service center, again replaced display component.

I hope issue will not repeat.

can any one suggest any tips and tricks.

I have purchased screen protector and smart cover from Mi store, to secure mobile device.

Just after 3 months visited Mi service center two times.

loosing faith and interest to use Mi devices.
