TheNokia Lumia 730 is a smartphone developed byNokia and released byMicrosoft Mobile that initially runs Microsoft'sWindows Phone 8.1 operating system. It was announced on September 4, 2014, atInternationale Funkausstellung Berlin, just a few months afterMicrosoft bought Nokia's mobile division and renamed it Microsoft Mobile. It was released in October 2014. It is a successor to the 2013Nokia Lumia 720 and marketed as aselfie phone.[1]
The phone has a 4.7-inch OLED capacitive touchscreen with a 66.0% screen-to-body ratio and a resolution of 720x1280 pixels (~316 ppi pixel density). The display features Nokia's ClearBlack polarisation filters and is protected by curvedGorilla Glass 3.
The Lumia 730 ships with Microsoft'sWindows Phone 8.1 operating system coupled with theLumia Denimfirmware update. It is upgradable toWindows 10 Mobile.[2]
The Lumia 730 has aQualcommSnapdragon 400 MSM8926SoC with a 1.2 GHz quad-coreARM Cortex-A7 CPU and a QualcommAdreno 305 GPU. There is 1 GB of RAM and 8 GB of internal storage; the latter can be expanded withMicroSD cards up to 128 GB in size.
The Lumia 730 has a 6.7 MP PureView-branded rear camera, sporting a 1/3.4-inchBSI sensor with 1.12 μm pixels and an Carl Zeiss 6-element lens with an f/1.9 aperture. The camera supports1080p video capture and is complemented by an LED flash. The front camera has a 5 MP sensor with a wide-angle f/2.4 lens and supports1080p video recording.
Many users reported that after upgrading to Windows 10, the front camera stopped being able to properly focus at normal distances, only focusing properly at very near distances. The problem was not fixed if one downgraded the unit back to Windows Phone 8.1. Newer builds did not solve the problem either once it appeared.[citation needed]
