In one sentence, describe what the following article is about: In some phones—typically Samsung brands—you need to remove a second back piece to access your speaker openings. These phones will have 10 to 13 more screws to remove, although the exact number varies by model and manufacturer. Use a #3 Phillips 4 inch (10 cm) screwdriver to turn each screw counterclockwise until they come loose. Afterward, pull off the second back piece.  Pull of the plastic film covering the screws if your phone has one. Once the second back piece is off, you can access and clean speaker openings and speakers. However, in some cases you will only be able to clean the openings. Snap the back piece back on when you're finished cleaning the speakers and reattach the screws. Afterward, you can reattach the metal covers to the speakers and snap the back lid back on.
Summary: Remove the second back piece if you still can't access your speakers.

Thin to moderate weight paper works better than heavy paper, but otherwise, the only limit here is your imagination. Collect several sheets of paper in nearly any pattern or design that appeals to you.  Some good sources can include wrapping paper, old magazines, old books, comics, and crossword puzzles. If you are unable to find anything you like in print, you can also find images you like online and print them onto standard printer paper. When selecting images and patterns, pay close attention to the size of the print. You'll need to make sure that the pattern is small enough to fit over the surface of your shoe. Take color into consideration, too. Arrange your images in a pile and make sure that the colors work well together. The easiest size to work with will be postage-sized squares—approximately 1 inch (2.5 cm) around all sides.  You can also cut the paper into small strips or cut out individual shapes from the pattern. Small pieces work best since they will crease less when you apply the paper around the curves of the shoe. Cutting the paper with scissors will create smooth, straight edges. Another option would be to simply tear the paper into small pieces. Doing so will create ragged edges and give the finished shoes a different sort of look. While not strictly essential, it's usually a good idea to spread out your cut pieces and plan a layout or overall design for your shoes. You may need to make alterations to the layout as you actually apply the pieces, but giving yourself a rough estimate of how the design should look can make the application part of the process seem less intimidating. Find a good pair of leather or faux leather shoes. Solid color shoes with a smooth surface and minimal detail will work best.  This project is a great way to add new life to an old pair of shoes, but if you don't have a pair lying around, you can probably find some at a thrift store. By choosing a solid color shoe, you'll guarantee that the decorative paper will be the focal point instead of the pattern beneath. Shoes with grommets, laces, straps, and other details can be a bad choice since you'll need to decoupage around these elements. Doing so isn't impossible, but it will make the project more complex. Wipe the shoes down with a damp rag or baby wipe to clean away any surface dirt and debris. The shoes do not need to thoroughly cleaned, but you shouldn't see any large clumps of dirt or grime. Stains and deeply imbedded dirt can be left alone, though. If you choose patent leather shoes, it's a good idea to lightly buff and scuff the surface with a patch of sandpaper before continuing further.  A nail file can also be used to scuff the shoes. Scuffing shiny, smooth surfaces can give the paste something to sink into when you apply it, creating a more secure bond in the process. Note that this scuffing process is not necessary if the shoes already have a matte or rough surface. In a glass or plastic bowl, combine equal parts PVA glue and water. Stir them together with a popsicle stick or disposable wooden chopstick until thoroughly combined.  Note that PVA glue is merely standard white glue. Another option would be to purchase Mod Podge or similar commercial decoupage glue. Make sure that whatever you choose will create a permanent bond and a clear, smooth finish.

Summary:
Schedule 20 pipes (also called DWVs) are the least rigid PVC pipes. 1/2 inch (1.27 cm) plumbing grade PVC pipes are also extremely flexible, but they lack strength and can kink when bent.
