Screen my screen and all the settings are upside down! when i swivel the phone the screen is still upside down! help!!

The phone uses two magnets which are located behind the lcd screen to sense when the screen has been swiveled away. There are two sensors which are built into the keyboard which senses the change in magnetic flux. I guess that there are two so that one can determine to which direction the screen was swiveled. So what could happen, is that the keyboard does not make proper contact with the main board within the phone and this can be the cause to the problem. It seems like when too much pressure is applied to the keyboard over time, that the contact pads on the keyboard wears out. So by replacing the keyboard pcb, the problem would likely be solved. One could of course try to fix these pads. One other possibility is that there is something wrong with the magnets behind the lcd. Either missing or misplaced or they are so old that they do not have a sufficient magnetic flux any longer, but I guess that is less likely.

Based on someone981 comments. I open up the phone and changing the keypad was not my option. Then i check the magnet. One of the magnet was going to peel off. So I peel off and reverse the suspected problem magnet by applying double side tape to stick on the metal plate. And it works beautifully. Have to clean the old sticky material that applied on the magnet before applying new double sided tape to avoid too much gap between magnet and the sensors under the keypad.

Sounds like your ribbon cable is loose, or perhaps you need a new one

Got into settings an display an turn on swivel animation
