Samsung SGH T639 Specifications, Tests and Review

Design of Samsung SGH T639 has dimensions of 94 mm × 38 mm × 17 mm and weight of 91 g.

LCD displays are currently taking a back seat. This is mainly due to higher power consumption. In addition, they have the disadvantage of lower colour contrast, which can be reflected e.g. in the resulting photos. On the other hand, phones with LCD displays are in general cheaper than those with OLED technology.

Display Resolution of Samsung SGH T639 is 176 x 220 pixels. A higher display resolution is a prerequisite for a sharper image. The standard for mid-range phones today is a Full HD resolution of 1920 × 1080 px. Cheaper phones, which usually have a smaller diagonal, have an HD resolution of 1280 × 720 px. Smaller resolutions can only be found in older models. Best phones, on the other hand, have a 4K resolution of 3840 x 2160 px.

In addition, if you need more memory, this model offers the option of inserting a memory card to increase the storage size.

The rear camera of the Samsung SGH T639 has only one lens. Single lens is more typical for older phones or lower-end phones with lower quality cameras. The rear cameras of modern phones nowadays are usually equipped with two, three and sometimes even five rear camera lenses. A high resolution lens alone does not necessarily mean high quality photos. The main lens in this has a resolution of 1.3 Megapixel. However, if you are looking for perfect photos, in addition to resolution, don't forget to focus on at other parameters such as lens aperture or pixel size.

Standby time is 250 hours. The value indicates how long your phone will last on a single charge when you are not actively using it. The battery life when making calls is, like standby time, a figure that tells us how long the phone will last on a single charge when making continuous calls. For the Samsung SGH T639 it is 240 minutes.

Bluetooth makes it easy to connect your phone to other wireless devices such as headphones, speakers, TV or tablet and more.
