Minimum screen resolution for Android devices

Question

Please, what is the device with the minimum screen resolution on the market?

Answer 1

Take a look at Supporting Multiple Screens to see all of the possible screen resolutions, and Screen Sizes and Densities to see what the current Android market looks like in terms of both measurements.

Right now a "Small Screen with Low Density" has an expected resolution of 240x320, so you can think of that as the market's minimal screen resolution for now (until Google updates these figures).

Answer 2

The most current Android O requirements for screens are here:

The smallest screen now applies to Android Watches (1.1 to 2.5 inches). Refer to section "2.4. Watch Requirements".

Answer 3

This is a device (a smart watch) with 240 x 240 resolution: http://www.omate.com

Answer 4

The current minimum values for android compatibility have changed from those shown in the accepted answer. Minimum size for recent versions of Android is 426x320, except for devices defined as watches which must have at least 120dpi and a diagonal size of at least 1.1 inches. As watches are permitted to be square (which other devices are not), this means the lowest permissible resolution of a watch is 1.1/sqrt2 * 120 = 93x93. In reality, this would probably not work, as I doubt the system UI would function in that size.

Answer 5

According to the latest Compatibility Definition Document, the definition for screen configurations require that:

• Screens MUST be at least 2.5 inches in physical diagonal size
• Density MUST be at least 100 dpi
• The aspect ratio MUST be between 1.333 (4:3) and 1.779 (16:9)
• The display technology used consists of square pixels

In practical terms, the lowest screen resolution currently being used is QVGA (240x320). There are a couple of phones that use this resolution including the HTC Tattoo and Wildfire. The smallest device I'm aware of is the 2.55" QVGA Sony Ericsson X10 Mini.

Answer 6

The smallest screen is probably the HTC Tattoo with a size of 2.8 inches. The resolution of that screen is QVGA (240×320, low density, small screen).
