Hello, after I updated my desire to latest supported android version via the system of the phone, several core programs and functions ceased from working. To solve these problems, I have tried resetting the factory settings, as well as updating to the latest supported-unrecommended version of android. Neither of these fixed any of the problems I'm experiencing . Concerning the problems, I will name the three major ones: 1) During a phone call my screen goes plank and the sound switches to speaker. This is especially annoying because the only way I can end a call is by removing the battery. 2) The camera does not function at all. Not just in the android's default app, but in any that uses it. 3) Headphones have no function. All sound is always forced through the speakers, even if I have my headphones plugged in. If anyone has a fix, please.
