iPhone 5 Screen won't rotate

Thanks all for your response. Do you have any instructions or images of where/how the gyroscope can be fixed?

Thank you Cathy. You're the only one that helped me unlock the 5th icon on top, the orientation works now!

Did not know about swiping bottom to top--it fixed orientation problem which occurred after I upgraded the system. Much thanks!

Thanks, didn't know that either!

Indeed just helped me now, after new upgrade of IOS, it was no longer rotating, now sorted

This was brilliant. I had been trying to fix this since last night and read your directions and now life is back to normal. Thank you.

Thanks. I'll give that a try today. Any chance that you may have a repair tutorial or any documentation on how to fix the gyro/accelerometer?

Logic board repair is very complex and require a lot of skill. First you have to remove the EMI shield, then diagnose the problem, then replace faulty components.

UPDATE: OK folks, I screwed up. When the battery was replaced, I failed to keep track of each individual screw removed from the square-ish RFI shield over the cable connectors. The 4 screws have 3 different lengths, and the differences are indistinguishable to the unaided eye. This is covered (briefly) in the video how-to guide, but in greater detail in the online step-by-step guide.

Failure to put the correct screws back in the correct holes can (at best) disable the sensors. At worst, you can wreck the logic board.

If all functions other than the sensors seem to be working fine, and you've just replaced the battery, then here is what to do:

Get a micrometer. Re-open the phone and remove the RFI shield over the 3 connectors at the top of the phone. Using the micrometer, measure all 4 screw lengths. You will need good lighting, fine tweezers, and even finer motor skills. You may also find a magnifying glass stand helpful. More in next comment

THEN: using the step by step online guide, insert the two shorter screws in the appropriate holes and snug them down. These have different lengths and are not interchangable!

Next, use the magnetic tipped screwdriver to try to distinguish which of two 1.7 mm screws is more magnetic. Put it in the correct hole. Ditto with the other 1.7 mm screw.

Before connecting the home button cable, power up the phone temporarily and check the sensors are working. If not, then power down, swap the two 1.7 mm screws, and try again. This should fix the problem.

Finally, power down again, reassemble, and enjoy the relief of recovering from a scary experience!

Thank you Tom. This was the only helpful post I could find! I replaced my battery and used a scanditech kit. This step was not clearly defined about the different screw sizes properly. I reorganized the screws and voila, everything works perfectly.

Thank you Tom. This was really the only helpful post I found!

I guess the problem with the gyroscope and compass is the magnetic field of the screws. Because they need to have their own magnetic field, they just work with the non magnetic screw in the right place :)

Solved my issue Tom. Thanks.

Found the right location of the screws by googling it.

compass is not working
