I am using Microsoft Lumia 540 smart phone since 11 Aug 2015, I bought this phone by mistake because without compare other brands.After 6 months of purchasing its having battery charging and battery saving problem and I went for service center but they took time 28 days and my all contacts and apps are removed from the mobile this is very panic for me. Sound Reception not good e.g. if u want listen music. style and design is very heavy comparing other brands ranges smart phone and not ease to use for a new person.It is use full only office working persons.Reliability and durability is good but I am recommending to others. according to my opinion this phone is not value for money.
