Drywall is subject to expansion and contraction.

You should know how to repair drywall corners if you are experiencing this problem. For this procedure, you should be prepared with the proper tools and materials. Keep in mind that your safety comes first since you will be using tools that require force.
The first simple tactic for drywall corner repairs is removing the drywall and checking the problem from both sides. The most common problem is usually because the two sides of the corner have been separated significantly because of the house settling and maybe due to problems with water leaks. The drywall must be re-attached to the wood foundations properly to make the corner strong. Experts suggest the use of drywall screws and a drywall screw gun for this problem as they are built for this kind of problem and may offer significant results in firmly putting the drywall in place. The screws can also be adjusted depending on how deep the screw should go in the foundation. After re-attaching the drywall, take out the tape used to strengthen the wall and examine it closely. If there are bubbles in the corner, it can easily be remedied by the use of a utility knife and cut it out. For cracks, use the utility knife to open them slightly to allow the joint compound to easily slip in and fill the area.
Another simple tactic for drywall corner repairs is by replacing the corners completely. After removing the corner, it is important to replace the tape used to fasten the drywall in the surface. For corners, it is best to use paper drywall tapes at it easily work well inside corners. The compound to be used must look like a toothpaste mixture to allow the corners to look sharp and easy to work with. Apply the compound inside the corner and spread it evenly. Fold the paper tape in half and place it on top of the compound. Always make sure to check if the compound covered the entire area to make sure there would be no empty spots and bubbles once the area is finished. The tape would then be used to squeeze out the compound carefully and leave on the wall overnight to dry. The second coat for the surface would now hide the tape and make the corner smooth. Leave the place to dry and once it is dry enough, sand it with a specially designed drywall sanding sponge. Ordinary sandpapers cannot fully cover the corner surface as it can only cover the general area. To fully get a smooth and even surface, repeat the procedure until you are satisfied. Finish off the repair by coating the drywall with paint primer before completely painting it.
