Try to restore software after full Backup if not work you need to take your laptop to a professional.

In short, no. The button is specially designed to work with the TouchID sensor, and in fact, Apple only sells the entire assembly, not just the button cap. It is certainly possible on a technical level for someone to create a compatible button cap in another color, but I'm unaware of anyone doing it.

Hi, Try a factory restore to prove whether the problem is software or hardware related. Before you perform the factory restore, backup the phone using the phone's backup feature. Ensure that the battery is fully charged before you restore the phone. Factory restore (also known as a hard reset) the phone using the phone's factory restore feature. Be aware that a factory restore will erase all your data and downloaded apps. It will be like when you first got it. That is why it is important to do a backup first . Once the phone has been reset test the camera to see if it works OK or not. If it does then restore the phone with the backup that you made earlier, using the phone's restore feature. If the camera still works OK then the reset has fixed the problem. If the camera doesn't work OK again then perhaps a downloaded app is the cause of the problem. the trick is to find out which one. If it doesn't then it may be that the camera itself has failed or perhaps it has a loose connection. Electronic components...

It may happen. If you checked previous suggestions - checking your own ears (switching earbuds left<>right) - checking if your media player/sound card have sound balanced (same level for left and right ear) - checking if its not clogged It may very well be just plain simple failure of hardware. I had before earbuds in which one side started to sound lower, after i checked all these things it was really just failure of hardware, I fought it by adjusting balance (put it more to side which got lower volume and increase overall volume) But it kept decreasing until it was so low that having balance completely to that side had no effect. It may be same case. If you check all above and earbuds are still under warranty, return it to store. If no maybe start looking for replacement (meanwhile you can adjust it as I did by switching balance toward failing side).

The problem is that your digitizer is broken/loose connection. It is repairable. The charge for the repair will completely depend on who you take the unit to. I do not think that the manufacturer warranty will cover it, but if you are paying for insurance, physical damage should be covered. It completely depends on what kind of insurance you have on the device. Hopefully your insurance will cover this incident. If not, seek a local repair shop and get a quote.

Basic Drill From Apple: Apple products are made with a variety of materials, and each product might have specific cleaning requirements which vary by the part you're cleaning. To get started, here are some tips that apply to all products: Use only a soft, lint-free cloth. Avoid abrasive cloths, towels, paper towels, and similar items that might cause damage. (1) Unplug all external power sources, devices, and cables. (2) Keep liquids away from the product. (3) Don't get moisture into any openings. (4) Don't use aerosol sprays, solvents, or abrasives. (5) Don't spray cleaners directly onto the item.
