Intex V.SHOW Projector Mobile Phone

Intex Technologies has come up with the Intex V.SHOW mobile phone, which features an in-built projector to combine projection with mobility. The phone allows users to project movies, pictures, music videos (saved in the phone and from Internet) and other Internet content up to 154.9 cms (61 inches) of screen/wall with a high intensity projection of 10 lumens and QWVGA resolution. Projection can be enjoyed up to a distance of 12 ft (between the screen/wall and the phone).

Its long-life battery ensures that you can watch a film for as long as three hours and a film quality of 25 frames per second (FPS) – which is as good as the FPS used in movies. Other features include insertion of ‘Bolt’ in the software – a fast mobile Internet browser and a Tripod stand as one of the accessories in the box (for an easy, hands-free visual experience). The phone is a touch-screen dual SIM (GSM + GSM) variant and also has another feature - dual screen mode (phone screen mode and projector screen mode are simultaneously active). It comes with dual camera and a dual card memory slot of 8 GB each to expand the internal memory of 64 MB.

Taking the visual experience to a new high are the clarity adjustor (present just below the projector lens) to modify the distance and quality of images as per the user’s comfort and freedom to capture stills from the movies (to be used as wallpapers). One can also convert the screen output from portrait to landscape and vice versa. It is FM radio (wireless and wired) enabled, with GPRS connectivity and has a 8.1 cms (3.2 inches) dust resistant touch screen.

Speaking at the event, Ramesh A. Vaswani, executive vice chairman, Intex Technologies, said, “I am confident that Intex V.SHOW will change the way people watch movies, videos, picture galleries and even read e-books on their mobile phones. If positioned judiciously, it could emerge as a powerful infotainment tool too. We are in touch with leading chip development companies of the world for future enhancements in this model.”

Elaborating on the technicalities, Debu K Dasgupta, head-centre for design and development, Intex Technologies, added, “It can receive multimedia content remotely through GPRS connectivity which makes it a valuable tool for streaming of content anywhere- commuting in public transport, spending leisure time outdoors/ cafés, remote locations, etc. Along with provision of front and back cameras and customised Java applications, the phone’s sound output through built-in speaker can be further be enhanced through external amplifiers/ headphone speakers.”

Samsung SGH-X120 Cell Phone Service Manual

Samsung 120 x 100x series continue. This is essential phones OLED screen, and I can assure you that colours and the screen is really good for your phone. But my opinion is that the display is the only good thing in this phone.

This phone has a polyphony of 64. 64 Of course, polyphony is a good thing, but the bad is that when you turn on the highest level of the melody You still not well understood. When you turn the phone in your pocket, you will probably not there for the phone to ring because even the highest level is really quiet. Ringtones sounds like sampler. Also the battery works really poor, you have to load offten. One last thing, but I am not sure Irda has not worked for me. I have heard that some people have the same problem with this phone.
