It's not necessarily the installation process which goes wrong. A file which is non-essential (a sound file for example) may have been corrupted for any number of reasons, and a simple re-install re-writes the corrupted file. It's the same principle as with a computer application. An error pops up at a random time, yet the rest of the program still works.
Without more details, this leaves just two options: perform a factory-reset (see the corresponding tag-wiki for details) and see whether that helps if a factory-reset doesn't bring it back to working order, send it for repair. Your warranty should still apply.
