[FIX] Pops and crackles in headphone output.

---

Hey everyone, just thought I would let it be known that (at least on my phone) overclocking past 1.8GHz causes horrible clicks and pops when listening through the headphone jack. I am using the Rogers Stock ROM with the latest KT747 kernel, and the issue appears when clocked to 1.89GHz, even though the rest of the phone runs stable. Took me a while to track down the problem!

I was hoping people with other kernels/roms/configurations could weigh in to see if this is an isolated or a widespread issue. For the time being I have just decided to overclock manually when it is needed.

EDIT: It appears after more testing that it was the kernel itself. Switching to stock kernel fixed the problem.

isn't your phone blazing hot to the hand?

Suprisingly the temperature increase is hardly noticeable. I tested while playing N. O. V. A. 3 and a few other games. My One XL got burning hot while overclocked to 1.7GHz, even though it's the same chip, which I find strange.

I had this probelm as well on my SGS3, ended up exchanging my phone for another reason and the new phone doesnt do it anymore.

The galaxy s3 explodes with stock temps, I would be afraid to oc to 1.9GHz Oh, and I would edit the title from [FIX] it's kind of misleading since there isn't a fix here.

I'm still trying to figure out when you would "need" to overclock.

I'm a power user. I do just about everything with my phone, including lots of gaming with emulators. Perhaps I got a higher than normal quality chunk of silicon, but the phone didn't overheat at all, even when overclocked. The only time it got noticeably warm was while overclocked, gaming and charging all at once.

To those having this problem, it appears it wasn't related to overclocking after all, as the issue appeared a day later on stock frequencies. Changing back to a stock kernel fixed the problem.

In the end I sold it and bought an international SGS3 from eBay. I don't care for LTE, but the Wolfson DAC and Mali-400 GPU appeal to my usage case nicely.

Seeing posts like this just make me cry inside...from the day I first got my phone and activated it, I have been having overheating problems. No one would take my device back so after my 30 day "return" period or whatever, I decided to root my phone to underclock/undervolt to solve my problem....but even know, my phone gets warm by just using stock Browser after a fresh install (not Chrome or anything else) WITH underclocking.
