Ringing volume.

I wondered why i kept missing calls... The chuffing speaker hole is on the flat rear of the 640 and when its put down on a flat surface you cant hear it. Some donut made a design clanger there..

One way to solve this problem is to use a case that has ridges on the back. When you lay the phone down, face up, the ridges on the back will hold the phone up off the table/desk surface allowing the sound (phone ringing) to escape.

Example of such a case for Lumia 640:
Amazon.com: Microsoft Lumia 640 Case, CASEFORMERS Duo Armor BLACK for Microsoft Lumia 640 Combo Case with Stand and Holster: Electronics

They make a similar case for Lumia 640 XL, which is the one I plan to get when Lumia 640 XL comes to my area.

Agreed, but i dont want a case on it as its a big phone already. A case just makes it bigger. Im gonna drill some tinny holes in the side i think...

Wont it be good to just attach some thin line? or a better way to insert round ring with cuts on top to the speaker hole so that the ring will keep phone raised and cuts will allow sound to be loud
just like this with cuts on one side...

Ive had another idea. I can just glue a thin strip of something (not sure what yet- piece of plastic) across the back of the fone just above the speaker hole. Just enough so that there is a small gap when laid face up. Bingo.

why not try those small things coming with laptops and speakers? some stickers...

If you go to Amazon.com and do a search for "self-adhesive clear rubber feet" you might get some ideas from this.
You can buy these kinds of things in an office supply store, and probably in a smaller quantity.

Just a thought.
