Let me begin by saying this method is just a workaround - the dark side of Android is, unfortunately, the multitude of screen sizes and densities we designers and developers need to work with, and the only way to create pixel-perfect assets in Photoshop is doing it manually. The following solution works only in Photoshop, as far as I know: If I understand ...
For an optimum screen-viewable PDF, don't export as a Print PDF. Choose Interactive PDF instead, and ensure that your Jpeg Quality is set to Maximum @ 144 ppi (a good compromise between low and high resolution monitors). As a note, also verify that your .indd is using RGB, not CMYK, and the transparency blend space (under the Edit menu) is set to RGB. ...
Yes, if your asset is 55 pixels for the 1× size, then you'll be after 110 for 2× and 165 for 3×. The iPhone 6 Plus should be treated as a full 3× UI scale device. You should use a 1242 × 2208px canvas when designing a full screen mockup. This is because the iPhone 6 Plus renders internally to a larger virtual canvas, then bitmap scales the entire screen ...

Then take the Crop-Tool (standard Shortcut: C) and change the mode in the Top-bar to Fixed-Size and type in 62cm as width and 182 cm as height. You can leave the Resolution blank. Then ...
Crop the image to just the part you need first, then, in the Edit > Image Size dialog, uncheck the Resample option and change the size to what you need.
150 ppi is plenty of resolution if you're printing on canvas. If you expect your piece to be viewed from a few inches away (less than 16), then 300 ppi is more than sufficient. Beyond that point you're just adding to the file size without adding visible image information in the final product. On high-grade art paper, you can go as high as 600 ppi. Beyond ...
