When I select a voicemail, it sometimes turns grey, and a voicemail one or two above becomes selected. Screen will also...

There are a number of YouTube videos that suggest removing the batteries, then washing the keyboard in a dishwasher without soap (and without JetDry please), then drying it for four days or so in a warm location. I don't think I'd go so far as to put it in a dishwasher, but you could put it in a container and add distilled water, then press each key a few times to help the water circulate underneath each key to help wash away whatever gunk you spilled on the keyboard. Change the water and do it a couple more times to remove as much of the sticky stuff as possible. Then dry for four days in a warm area, or use the 'put it in a bag with rice' trick. I'd do this only if I'd given up and was ready to buy a new keyboard. Sort of a last ditch attempt to try to save the keyboard. If all else fails, take it completely apart and sell the pieces on eBay to others who need the parts!

Run hot water on the metal around the stuck endcap. You are attempting to heat up this area to get the aluminum to expand a bit. Be careful not to get water into the keys. I was able to successfully unscrew a stuck endcap with this technique.

Try replacing the camera and flex assembly.

You can find it on eBay. It is sold along with the two clear plastic pieces.

You will need to replace the flex assembly.

When replacing the battery, be careful not to open the LCD more than 90 degrees. You may have damaged a flex cable assembly or possibly the connector may not be seated correctly, although unless you removed the connector cover, that is unlikely. Or if you had to pry the battery out, you may have damaged something else. Since the cameras are on different connectors it doesn't sound like something simple.

Seems unlikely. The glass is glued to the LCD assembly, and there are no gaps where dust could get under anything. I've heard of people replacing the glass without reglueing it, which could allow dust in. But I'm not sure how dust would get in the phone in the first place.

Use just a dot of B-7000 adhesive at each end. It has a pinpoint applicator that makes it easy to get just the right amount, in just the right place. You don't really need the glue, the speaker will hold it in place as you assemble it if you are careful. Also great for gluing the frame to the glass. (Some replacement frames come with glue already applied. Just heat with your LCD separates machine and it will melt enough to adhere.)

Just Google it. There are a number of manufacturers. Some are available on eBay. There is a nice basic temperature controlled LCD Separator Machine for just $35. Expect to destroy a few LCD assemblies learning how to do it, so practice with some scrap displays.

Try resoldering the flex cable. Otherwise one of the flex PCBs is likely damaged.

Warm the area where battery screw cover is in a stream of hot water from the faucet. Be careful not to get water into the keyboard or keys. The warmth will sometimes expand the aluminum enough to loosen the screw cover. Worked for mine.
