Siemens has received the green light from operators to patch a software defect in some of its 65 series mobile phones which could cause hearing damage.
In a laboratory test, company researchers discovered that when batteries in this series run down during a call, the disconnection warning tune can play extremely loudly and cause ear damage.
Siemens was warned of the defect on 26 August and advised customers to deactivate the disconnection tune until it released a software patch for its 65 series mobile phones, including the C65, CX65, M65, S65 and SL65, as well as the CV65, CT65, CXV65 and CXT65.
The patch required testing and approval by the mobile phones operators before Siemens could offer it.
Customers can upgrade the software for free at local Siemens customer service centres and selected retailers and network operators.
In the future, Siemens plans to offer an automatic software upgrading service via mobile phone operators. Under the service, small components will be updated automatically when required, instead of replacing the entire device software.
The software can be downloaded at: siemens-mobile.com/software65.
