[One (M7) Q&A, Help & Troubleshooting] SPU2K:
Greetings XDA users! As you can see, this is my first post on this forum. I have registered here in order to get some answers from other users of the HTC One concerning some problems that I have experienced. I have been using the device since more than a week now, and these are the issues I've come across so far, so please let me know which ones of these you are experiencing as well:

1. YouTube audio / video out of sync

I noticed this the first time I used YouTube on my HTC One. Lip sync simply looked horrible while watching some videos. To test if you have this issue as well, you should try something like this video where it can clearly be seen in action: Link (Since I cannot post links due to below 10 post count, simply search YouTube for "BBC HD audio sync test")

2. Simple games lag / do not play smoothly

The first game I tried on my HTC One was Doodle Jump. It's a very simple game, and before purchasing the One, I have read about other recent HTC smartphones having problems with such simple games because some HTC devices don't know how to properly use their GPU/CPU in situations where games don't have high demands. If this is still the case with the HTC One, and not just some issue with my own, it is simply unacceptable. After all, a new flagship smartphone should not have any issues when playing the most simple of games that any old android smartphone can do perfectly.

Note: I have already tried to cure both of these problems by doing it with / without power savings enabled. I have also tried with / without Beats, Bluetooth, NFC and so on. Nothing helps.

Please let me know if you are experiencing these two issues on your HTC One as well.

Other issues and annoyances I have noticed, that come to mind right now:

3. Blinkfeed share bar at the bottom of the screen is very annoying, and apparently can't be removed at all. It's doubly annoying because sometimes you can hit this bar when trying to use the back button.

4. 3-dot-menu bar at the bottom of the screen in some apps. There even used to be a built-in feature in the setting menu to get rid of this, but HTC seems to have removed this in the final software versions, for questionable reasons.

5. Video camera settings such as 60-FPS-HD or slow motion keep resetting themselves each time the screen gets locked and go back to "Normal".

6. Audio issues (cracks / pops) when using YouTube (maybe other apps as well). This happens especially often with Beats turned on, but I have also heard it happening with Beats off.

7. Odd volume jump that happens around 80% volume when increasing volume while streaming music via Bluetooth. (Volume actually goes down instead of up, and the next step after this sounds much louder than just 2 "clicks" more.)

8. Wifi reception gets a lot worse when covering the upper side of the device with my hand. And by covering I mean holding it normally in landscape orientation, I'm not intentionally trying to smother the signal. This is quite noticeable in areas where the signal is not that strong to begin with, as I've experienced multiple times that I've choked my wifi signal by simply holding it that way to watch some YouTube videos. The wifi bar can jump from 2-3 bars to just the dot by doing this.
