It is the information of manufacturing cell phone jammer . Why then had it malfunctioned just after a short 6 months? Checking the warranty card that came with the mobile phone revealed that as long as I could get the mobile phone shipped back to the agent that I purchased it from, I could get it repaired without charges as it was still under warranty.In fact, I could also get service for it as long as I could send it to an authorized Sony Service Center agent within Australia itself, but since I was going to be in Malaysia again, while it was still within the warranty period, I chose to give the distributor who sold the mobile phone to me another visit to get it repaired. The sales agent dutifully noted the particulars of the Sony mobile phone, and said as it was one of the newer mobile phones, he would need to send it off to the authorized service center to repair it, and would give me a call as to the status of the repair. So I could heave a relief as I thought all things were being taken care off. In the end, there was a conspicious absence of a phone call from the agent and getting in touch with them, I was told the mobile phone could not be repaired free of charge even during its warranty period!Now, if you are a mobile phone user, this rings alarm bells...because when is it a warranty for an expensive branded mobile phone is not a warranty? After all, the Sony mobile phone isn't a brand of electronics and communication technology to be taken lightly- it is an established brand! "We have opened up your mobile phone and we find it was mouldy inside. Your warranty is thus voided because of the mould!", the agent repaired, probably reading from the report from the authorized service center. Amorphous plastic molecular shape and molecular arrangement in crystalline structure showed disorder-like plastic (such as ABS, the PC, the PSU, PMMA, PS), 1-2-3 showing the fundamental behavior of thermoplastics in a specific temperature range according to the heat repeated heating to soften and cooling hardening. Thermosetting plastic heat does not melt the material, heat no longer has the plasticity again. Urine - phenomena and solutions of formaldehyde resin (UF) and (PF injection molding defects such as melamine - formaldehyde resin (MF) cracking cracking is more common a defect of plastic products, the main causes of attributed to the stress and deformation. residual stress, external stress and the external environment arising from the stress and deformation.
