lol he probably didnt notice that it was set to maximum 2 cores by default i just put 4 on and got 14658 in antutu
[Nexus 7 Android Development] SquireSCA:
Let me ask this... What is the benefit of only running 2 cores? An extra 25 minutes of battery?

Whether they make a real difference or not in most situations isn't much of a concern. I am sure that at times, like a game, or in multitasking, having the two extra cores does help. And when 90% of the power used, is the screen, disabling 2 cores and *potentially* harming performance, just doesn't seem like the best idea to me.

I would rather have them there for when they are needed, than to slightly cripple the device over a minimal battery life increase.

I notice a difference with 2 cores when I am installing a ton of apps, and it is downloading, installing, updating a ton of email in the background, etc...

It isn't about the best benchmark score, but when comparing one ROM to another, and they are all using 4 cores except this one, it is hard to get an apples to apples comparison to see if everything is running as it should, that's all.
[Nexus 7 Android Development] eduardo_b:
The thing is, the perception of difference is all that matters. If you feel that the performance is markedly different (don't forget the placebo effect), then go with the number of cores you sense offers better performance...assuming you are okay with battery usage. I'm doubtful installing apps and syncing e-mail is actually affected by the number of cores running. Too many other variables.

Re: [KERNEL][3G+WIFI][4.2.2] M-Kernel - a37

I had wifi issues before a35, but none since a36.

On the other hand, I have been getting an occasional random reboot while the device is in the (asus original) dock and charging has stopped/started a couple of times (usually happens when moving the thing around with the dock from the shaking).

Has anyone else had similar random reboots when charging on the dock?

Re: [KERNEL][3G+WIFI][4.2.2] M-Kernel - a37

It did disconnect exactly once, while I was going to write you that it worked. I don't know what to do with that. :confused:

[Nexus 7 Android Development] :
Re: [KERNEL][3G+WIFI][4.2.2] M-Kernel - a37

About one hour ago I flashed a36 and I could definitely see some instability, though not as bad as with a37.

After a few minutes the WiFi signal started jumping from the maximum to a 2-bars level every 10 seconds or so: a sign that it started switching between APs.

It stopped after a while and at the moment it seems to be working normally again.

As I wrote above, WiFi in a37 is significantly worse. I don't know what you changed between 35 and 36, and then between 36 and 37. However WiFi was apparently first damaged and then broken, from what I can see. Does it make sense to you?

Now it started again acting up... Let's see if I can send this.

Re: wifi

I know this isn't truly helpful, but I've noticed that at work, where there are a lot of APs available, it gets confused and jumps around. At home, with a bunch of nearby APs but only the one it can access, it's rock solid. My N4 also does this. The N4 is running AOSPA and Trinity 4, the N7 is running AOSPA and M-kernel.

3 max cores

are there any advantages to setting the max cores to 3? I know you can set it to two max cores with little loss to performance or 4 max cores for full performance obviously. I guess what Im asking is, does setting it to 3 max cores have an adequate advantage over setting it to 2 max cores, or are you just better off setting it at 4 max cores?

Re: [KERNEL][3G+WIFI][4.2.2] M-Kernel - a37

I have a sound problem on a37

The sound is getting very low so I have flashed the king beatz and the sound is also lower than it was . I flashed dirty aokp 5.0 and the same thing . PA . CM10.1 fusion ... :(so this problem I have it from a36 but 35 have no problems what so ever with dirty aokp 4.0

PS : To get confirmed I have tried the dirty aokp with Franco . m and lean . the sound was epic with lean and Franco but with m it is too low same as PA

PS2 : I have tried nexus louder version 3 beta 4 and it is the same

PS3: I have tried the PA 3.0 nightly with no mods too and it is the same

Sorry
[Nexus 7 Android Development] Metallice:
Okay that's great news. If test 4 has issues and test 5 doesn't, that means I (most likely) know exactly what the cause is.

Test 4 had all patches up to 68, and Test 5 had all patches up to 67 plus 69. So it looks like patch 68 (and 70 which is an update to 68) are the problem.

I need to hear from robertototaro first as he is the other user with this problem, hopefully he corroborates what you are saying. If he does, then I'd just need to release one more test build for you guys to confirm the issue is fixed.
[Nexus 7 Android Development] Metallice:
This was just recently discussed (assuming you're referring to speaker volume). (I hate saying this as it is said too often and often used unnecessarily in an elitist way when a simple answer would have sufficed, but...) In the future please read a few pages back to see if your question/comment/bug has been recently discussed.

The seemingly decreased speaker volume is a side effect of another beneficial tweak. Technically the peak sound volume isn't any lower.

If you had read through the OP :( , you would have seen that I disabled DRC, or "dynamic range compression", for the speakers in a36. Too be honest I'm not sure why the changelog for a36 wasn't the first thing you checked when you said yourself that the problem started there for you.

I'm no expert, but in essence DRC as it is used here increases volume of the quieter sounds so they are closer to the volume of the loudest sounds (Not really a true or accurate description but it works). This makes everything sound louder without increasing the maximum volume. Their are downsides to this however. It takes away the "punch" of your music by making everything practically same loudness. In music, for example, you might lose the "punch" everytime the drums are struck as they are no longer louder than the guitars playing at the same time.

So I do this for a couple of reasons. For one, I prefer maintaining audio quality over increasing the volume. There is no reason it has to be forced on you in the kernel level. Second, there is already a heavy dose of compression built-in to most audio recordings already, and I would rather avoid compressing them further. Third, There are many software methods to increase volume. You could use something like the JB louder audio patch or whatever, use an equalizer to raise all the levels, use an equalizer app that allows you to boost volume, and I'm sure there are many more.
[Nexus 7 Android Development] SquireSCA:
That is probably the best descriptions of DRC, what it does, pros and cons that I have read. Thanks!

[Nexus 7 Android Development] ezas:
Re: [KERNEL][3G+WIFI][4.2.2] M-Kernel - a37

The net result of compression should not be a net increase in volume. Think of it this way the ceiling in your room is volume, the limit of your amplifier to produce sound without distortion. Compression boosts the volume of a signal, including the quiet parts, with out the louder parts hitting the ceiling. But compression is also the loss of dynamic range, which is the trade off. Yes I know it can make it louder and/or sound louder, but I'm not going to go into that.

Compression is like putting a nozzle on a hose and a pressure regulator. Depending on the size of the nozzle and the settings of the pressure regulator you get different results. It's not a perfect analogy but it's close enough

Compression should not do the job of volume. But if that's your only option and/or the result sounds better to you that's what listening to music is about.

But having compression on all the time makes no more sense than having the room virtualizer on all the time.

I applaud Metallice for not using 'tricks' to get more volume.
