Have a Galaxy Note 4. All of a sudden, it stopped responding to screen touches. It's as if something is taxing the heck out of the CPU, and it's taking 10, 20 and 30 seconds or longer to respond. Occasionally, the phone just reboots.

Tried removing the flash card and sim card. No change on the flash. It might have improved a bit with the sim card gone.

Cleared system cache. No change.

Restored to factory settings, updated phone to latest software, and installed / updated my apps. No change.

Booted in safe mode. No change.

Other than sending it back to Samsung, are there any other steps I should try?

Thanks

 

I think I found the culprit.

If I disable Google Play Store Services, the phone acts pretty normally. I enable Play Store Services, and the phone slows to a crawl, and restarts.

Anyone else seen this?
