How Many Devices Can You Have Pixel Gun 3D
Vida Hubbert
I had noticed that when reading in an identical photograph across devices in the JPEG format, the pixel values do not match up. They are close, but different. When converted to PNG files, the pixel values seem to match up.
This would seem that it would be due to the (un)compression algorithms across devices. That's what comes to mind anyways. Is there a way to read in JPEG files so that the same pixels are retrieved from the photograph across devices? I don't see an option within the BitmapFactory Options component.
Other devices report different device pixel ratios, including non-integer ones. For example, the Nokia Lumia 1020 reports 1.6667, the Samsumg Galaxy S4 reports 3, and the Apple iPhone 6 Plus reports 2.46 (source: dpilove). But this does not change anything in principle, as you should never design for any one specific device.
This has lots of implications when it comes to web design, such as preparing high-definition image resources and carefully applying different images at different device pixel ratios. You wouldn't want to force a low-end device to download a very high resolution image, only to downscale it locally. You also don't want high-end devices to upscale low resolution images for a blurry user experience.
If you are stuck with bitmap images, to accommodate for many different device pixel ratios, you should use CSS Media Queries or the HTML picture Element to provide different sets of resources for different groups of devices. Combine this with nice tricks like background-size: cover or explicitly set the background-size to percentage values.
When viewing a web page, the CSS will think the device has a 375x667 resolution screen and Media Queries will respond as if the screen is 375x667. But the rendered elements on the screen will be twice as sharp as an actual 375x667 screen because there are twice as many physical pixels in the physical screen.
Purpose of DPR is to keep consistent size of CSS pixels and thereforeconsistent size of letters, symbols, images and everything else onscreen, across a variety of devices with different physical pixeldensities.
Thanks ..After raising this i was for pointing to this article.
What is more frustrating is that I can have muiltple fit bit devices - my Blaze (although rarely used) and flex were not removed. Only the charge 4 which isn't a "smart" watch nor is it equivllent to the Pixel watch in terms of function. So if it is possible why is it blocked for some devices ... need this resolved
Seriously don't understand why this isn't an option. I don't want to wear a $350 pixel watch to work where it's going to get damaged. I'd rather have a cheaper version for work, and a pixel the rest of the day. But no, that would be too convenient for the customer, and allow the company to make more money on device sales.
I have the same request\concern. I have been using Charge 5 for specific activities including sleep and outdoor sport in the beach. Just acquired the Pixel watch as my every day watch assuming I can have both devices in my same Fitbit account. Just found that Fitbit only allow one device per account which not make senses because that is why Fitbit has different models that customer can switch depending in the occasion.
Crazy to think there's a whole thread of people who want to buy MULTIPLE Fitbits, and the company is saying "No, you can only have one." There are just so many reasons this makes sense. I don't even care if you disable the "apps" on a secondary fitbit. For sleep, for intense exercise, for yardwork or manual labor, I have no interest or need in wearing a fancy "high end" pixel watch, just give me something very basic.

For many years, 96 ppi was a very common display density (hence CSS defining apixel as 1/96th of an inch). Starting in the 1980s it was the default resolutionof Windows. In addition, it was the resolution of CRTmonitors.
Since the introduction of the first Retina screen, device manufacturers have been in an arms race to create increasingly higher density screens. There are far too many devices and dpi resolutions for a sane person to keep track of.
While desktop and laptop displays are in landscape orientation (wider than tall), many mobile devices can be rotated to show websites in both landscape and portrait (taller than wide) orientations. This means that designers and developers must design for these differences.
Knowing that it is key to accommodate for the many different devices when designing websites, we have compiled a list of the most up-to-date devices with their respective pixel sizes and viewports below. We have also put this information into a handy downloadable PDF.
Since most digital hardware devices use dots or pixels, the size of the media (in inches) and the number of pixels (or dots) are directly related by the 'pixels per inch'. The following formula gives the number of pixels, horizontally or vertically, given the physical size of a format and the pixels per inch of the output:
Pixels per inch (or pixels per centimetre) describes the detail of an image file when the print size is known. For example, a 100100 pixel image printed in a 2 inch square has a resolution of 50 pixels per inch. Used this way, the measurement is meaningful when printing an image. In many applications, such as Adobe Photoshop, the program is designed so that one creates new images by specifying the output device and PPI (pixels per inch). Thus the output target is often defined upon creating the image.
This shows that the output banner will have only 40 pixels per inch. Since a printer device is capable of printing at 300 ppi, the resolution of the original image is well below what would be needed to create a decent quality banner, even if it looked good on a monitor for a website. We would say more directly that a 1920 1080 pixel image does not have enough pixels to be printed in a large format.
For example, a 15-inch (38 cm) display whose dimensions work out to 12 inches (30.48 cm) wide by 9 inches (22.86 cm) high, capable of a maximum 1024768 (or XGA) pixel resolution, can display around 85 PPI, or 33.46 PPCM, in both the horizontal and vertical directions. This figure is determined by dividing the width (or height) of the display area in pixels by the width (or height) of the display area in inches. It is possible for a display to have different horizontal and vertical PPI measurements (e.g., a typical 4:3 ratio CRT monitor showing a 12801024 mode computer display at maximum size, which is a 5:4 ratio, not quite the same as 4:3). The apparent PPI of a monitor depends upon the screen resolution (that is, the number of pixels) and the size of the screen in use; a monitor in 800600 mode has a lower PPI than does the same monitor in a 1024768 or 1280960 mode.
The dot pitch of a computer display determines the absolute limit of possible pixel density.Typical circa-2000 cathode ray tube or LCD computer displays range from 67 to 130 PPI, though desktop monitors have exceeded 200 PPI, and certain smartphone manufacturers' flagship mobile device models have been exceeding 500 PPI since 2014.
In January 2008, Kopin Corporation announced a 0.44 inch (1.12 cm) SVGA LCD with a pixel density of 2272 PPI (each pixel only 11.25 μm).[5][6] In 2011 they followed this up with a 3760-DPI 0.21-inch diagonal VGA colour display.[7] The manufacturer says they designed the LCD to be optically magnified, as in high-resolution eyewear devices.
The release tags for these devices have official builds and updates available. These devices meet the stringent privacy and security standards and have substantial upstream and downstream hardening specific to the devices.
GrapheneOS also supports generic targets, but these aren't suitable for production usage and are only intended for development and testing use. For mobile devices, the generic targets simply run on top of the underlying device support code (firmware, kernel, device trees, vendor code) rather than shipping it and keeping it updated. It would be possible to ship generic system images with separate updates for the device support code. However, it would be drastically more complicated to maintain and support due to combinations of different versions and it would cause complications for the hardening done by GrapheneOS. The motivation doesn't exist for GrapheneOS, since full updates with deltas to minimize bandwidth can be shipped for every device and GrapheneOS is the only party involved in providing the updates. For the same reason, it has little use for the ability to provide out-of-band updates to system image components including all the apps and many other components.
Devices are carefully chosen based on their merits rather than the project aiming to have broad device support. Broad device support is counter to the aims of the project, and the project will eventually be engaging in hardware and firmware level improvements rather than only offering suggestions and bug reports upstream for those areas. Much of the work on the project involves changes that are specific to different devices, and officially supported devices are the ones targeted by most of this ongoing work.
