Just bought a new I phone 5 s last month after few days home button started making cracking noise some times . Visited service centre in CR park Delhi they said take back up and come again as phone need replacement . So went back again to submit the phone this time they said its a regular feature after requesting they took it and returned it next days saying its fine and repaired now , but it was still making same noise . But such a expensive phone and now not happy with the service and response as still has same sound and why should I take repaired phone after buying and having defect in 30 days .

Don't know what to do now but the noise is very irritating and disturbing and button even gets hard but can't keep running to service centers and keep giving phone to them

Have more I phone 5 s at home and none of them makes noise like this
