Problem with home button and main camera

Hi folks!

I was hoping that some of you could help me with my strange problem with Iphone 6.

Namely, last time I opened my phone to fix front camera crescent moon problem, when I finished work on camera, I put flat cable connectors (LCD, front camera, home button and touch) in place on main board and closed phone frame. Nothing was damaged, scratched etc.

After that repair, I am having strange problem with, sometimes, unresponsive home button (home button wont wake screen, double tap does not work, wont exit app etc.), also, flash and back camera sometimes just wont work.

When this problem occurs, for example when I enter camera mode, I got yellow triangle with warning that indicates warm flash unit, besides the fact that I didn't use flash or camera,

After, for example, hard reset or just phone shut down, everything is working fine... for a half day, and after that the problem is back...

Could someone help me with this issue ?

Thank you in advance!

All the best

Alex

Sounds like there is some static or power surge build up within the phone. Might be worth unplugging the battery and holding the power button for 15 seconds then plugging the battery back in and see if that helps.

Camera IC sounds like it is getting overloaded / faulty and the home button issue not really sure what is causing that.

I believe that the FPC connectors on the various flexes are not seated properly. Unless you get a very satisfying "snap" feeling, I would check them again. These FPC connectors are delicate and are only rated for a dozen or so insertions. This is fine for a one off repair but it shows to what extent they can be easily damaged.

After you remove the screen assembly and it's flex connectors, visually inspect the connectors on the logic board with a magnifying glass or loupe. Sometimes, a single pin can be damaged and cause problems.

Dear Minho,

Thank you so much for your suggestion and help.

I did what you said. I oppened the phone, checked every connector for possible damage and put it all back, having in mind that every connector must "snap".

The other thing that I did, like the @benjamen50 suggested, I cleared phone form any possible static electricity that may be within the phone.

Since last Friday, thanks to You, there is no more problems with my phone.

Once again,

Thank You very much for the solution and help!

All the best!

Alex!
