Kernel Test Results

Good day Mr. Radu! After testing both kernels on CyanogenMod 10.2 Alpha 6, I can say the results were brilliant! :)

a- Kernel Variant 1:

Of course, upon performing the test, I flashed the alpha 6 with a pristine installation and no Google apps have been flashed with the ROM. Installation of the kernel was fine as well. After that, I booted the phone, went through CM Account setup, set the lockscreen to PIN lock, and installed Titanium Backup Pro (I have a backup .apk of my important applications). I opened Titanium Backup app and locked the screen. The lockscreen gave no issues even when Titanium Backup app is or is not running in the background. I even tested other apps in the background while phone was locked such as Messaging app and the Dialer app. Upon locking the screen multiple times and turning it on again, the lockscreen worked fine and no lags have been experienced. However Mr. Radu, here's a heads-up I would like to mention. I realized the kernel had something fishy, in which the available RAM was 341 MB (usually 342 MB) so I went on and tested the camera. The first picture was fine, but the second one caused the camera to freeze completely, and even closing the camera app and reopening it didn't solve this "bug". The Gallery app was accessible, but if you try and press the camera icon to quickly access the camera, the gallery app closes unexpectedly. Yet, this time when I pressed on the Camera app, the Camera displayed an error which says that the camera isn't connected. Just wanted to inform you about this issue Mr. Radu, as for lockscreen freezing, it's no longer there, additionally the status bar, notification page and the quick settings panel are all working flawlessly and no SystemUI issues at all, hence, I can confirm that the ROM issues are being caused by kernel-related annoyances.

b- Kernel Variant 2:

After being done from all testing on the first kernel variant, I went on and booted into recovery. The installation procedure only included wiping of cache and Dalvik cache (no data or system wipes have been performed). As expected, the phone booted and all preferences were saved, that is the lockscreen and installed apps (I only installed Titanium Backup to be honest). I did the same exact test as posted above which was originally mentioned by you, sir :) . The lockscreen did not give any freezes and it worked better than usual, with no lags whatsoever. So, the second kernel variant has no issues related to lockscreen and the ROM was running smooth, which indicates good performance. Again, I had some doubts about the Camera app and realized that the available RAM this time was less by one Megabyte (340 MB), but even while taking 6 pictures, I had no issues or shutdown, and the Gallery app worked fine too. Therefore, the second kernel variant, according to my tests, is better and smoother.

In case you missed anything in my posts above, Mr. Radu, here is a summary of what I did:

1- Kernel Variant 1: Flashed CM 10.2 Alpha 6 on pristine installation, flashed kernel variant 1, set the PIN lock, had more than 3 application run in the background, multiple screen locking, no lockscreen freeze bug at all. Note, camera had an issue.

2- Kernel Variant 2: Flashed kernel variant 2, wiped cache and Dalvik cache, locked the screen, multiple screen locking performed, no lockscreen freeze annoyance has been experienced. No camera or other issues.

Upon using CyanogenMod 10.2 Alpha 6 with default Linux kernel 3.4.86, performance and battery life were superb and optimal, I would like to thank you again Mr. Radu for all your work, and in the hope of my test results be important to you. God bless you, Mr. Radu, and shall I help you in making the ROM even better. Have a nice day, sir! :)
