It is one of the pathetic mobiles.
1)signal problem
2)ear piece problem
And also, some times loud speaker automatically get on. I have new piece , never buy this phone
the ear speaker is the loudspeaker.so your around hear your conversation Ii have the same problem with my Nokia 101. The only solution is put your finger in the loudspeaker and loud speaker on automatically and any one can listen your conversation and now I’m planned to buy Nokia X1-01.
I hope it makes me happy !
