My Z1 notification light is barely visible as the covering of the ear reciever is accumulated with dust. How to clean the ear reciever area as it is not advisable to use tools to remove the dust as it might damage waterproofing. Will appreciate for the reponses.
Solved! Go to Solution.
I gently used the cotton swab to pull out the dirt from the notification light groove, worked like a charm. Luckily did not cause any damage to the ear piece.
Use a cotton swap

Is it safe to use cotton bud, will it not effect waterproofing ?
Niceeeee.. You solved it by yourself... Hahahaha
Anyways, I appreciate your replies. Thank you.
