I bought Sony m4 Aqua 2 years back worth rs20,000. it is giving me a horrible nightmare. my both sim is not showing any signal from 8-10 days(sim card is working fine in another phone). I tried all the solutions which is given by your forum and which is on the internet. a month ago I fixed my mic and audio jack in rs2000 and two times I changed my sony data cable. now customer care service telling me to change the motherboard which cost you 8500. seriously I was a big fan of Sony products but seeing your product quality and customer service I am very disappointed. please give me solution about it!!!!
