[q] overclocking and kernel

Hey yall I have a newbie q and a for you
Im new to overclocking!
I had my phone unlocked, rooted, and they flashed a custom rom that overclocks the device form 600mhz stock to 796mhz.
HTC DEsire C:
Android 4.0.3
Sense 4.0
Slim Sense 1.0
My question is..by default the cpu speed is 796mhz now. When I whipe the phone with factory data reset, it still runs at max speed. Is this because the kernel is set to this by default? This is the max I want to run at, and basically apps like CPU Tuner are only underclocking the device? When I use CPU Tuner, Min is set to 122mhz and max is 796mhz. Also If I change the max cpu speed form an app, will it conflict with the kernel that runs at 796 by default? can I change the max cpu speed to any supported MHz I want through an app?
I would also love a few tips from the pros.
THankyou kindly.

Yes. Since the kernel is set to that speed by default, it'll stay so until you change it manually. CPU control apps may only do that since the kernel only allows that speed as the max (so there's nowhere but down ). There will be no conflict. You can only change it to frequencies the kernel allows.

Ty!
Perfect! thanks for the answer Theonew. Im going to play around with underclocking it
I would love to tune the cpu voltage but just don't have the cojones. Has it become safer in recent times? The guides I read on google are from a few years back. I understand there are risks like SoD sleep of death, maybe other risks too. Any tips?
Thanks again, You guys are great what a wealth of knowledge!
I love tuning.

If you do that, make sure you do it wisely. Undervolting can be dangerous if not done correctly and could damage your device. Go down in steps and use your device for a while after each step to see its stability. Do not make huge steps. Yes SoDs can occur if it is done too drastically. Read up more and try to learn as much as you can before attempting. Its only as safe as you make it .
You may also want to set profiles in SetCPU e.g. screen off - set the governor to conservative. No problem for the help .

Apps are a great way to go, especially SetCPU since you can make profiles to save battery! I would not mess with the voltage though, you can completely fry your phone permanently... I'd leave that to the pros. Chances are, the person that made the Kernal has all the voltages set properly, so you would only be messing up the work that has already been done for you... Just mess around with different profile settings on SetCPU to get the best battery life/power balance. Also, if you want to save even more battery and gain full control of your phone, check out Tasker! Tasker allows you to automate ANYTHING that you do on a regular basis, including toggling Wifi and bluetooth, and rebooting your phone daily.. or ANYTHING you can think of! Open the Music app when you plug in your headphones, turn on GPS when you open the Maps app.. the possibilities are endless! And it will save your battery! Hope this helps, good luck!

[Q] Lag throughout the tablet?

Hello all,
I recently bought the shield tablet but am having some problems with it. There appears to be an unusual amount of lag in things such as ui and games in the tablet. I had no possible reason for this to occur. Even while typing this message, the tablet is missing inputs on the touchscreen keyboard. I am running this rooted and stock. I am using folder mount to move all my obbs to the SD card (Samsung 64gb pro, 90Mb/80Mb). I used SD maid pro to disable the autostart on all the downloaded apps such as Gameloft games. I am using the default screen color correction and am using optimized power mode, but have not set the apps to be optimized.
From what I can see I have done everything I can to optimize the tablet, but all is in vain because things still seem to lag. Any help?

I have run into it a few times as well. Rebooting the device helps, also switching over to ART helped as well. At least as a temp fix.

I have heard the opposite actually. Many people said that dalvik was better. It seems as though it might be related to the folder mount since I have about 40gb worth of games. I went over the top.

I agree keep dalvic! Art seems to have a few issues, this will be sorted when the shield gets updated to 5.0

I too have some serious lag going on and I don't understand what is causing it. It really sucks. After a fresh reboot all is fine until an hour in. I'm not sure if it's the sd card causing it or not. I wish there were more replies here regarding it. We can't be the minority here with these problems.

I just bought this tablet and was having the same issues. I did a factory reset and switched to ART. Thing flies likes it's supposed to finally.

Use Greenify to manage background applications to better optimize performance. Sounds like this could be an issue with stock ROM. It may be that trying a custom AOSP ROM like Vanir might be of great benefit, though it was just released recently and could have issues. It's worth trying if all else fails.
Oh yeah if it's an SD card issue, it might be resolved by installing the "KitKat SD Card Full Access" XPOSED module. KitKat's changes involving the SD Card may be interfering with Foldermount, so this would fix it in that case.

I'm really hating the lag on this device. After a few swypes in Nova Launcher, the lag starts. This is a stupidly powerful device. Why is this happening!! Tried formatting, and unrooting.

Think it is a known bug, according to NVIDIA forums, supposedly fix in next update.

Try changing I/O schedular
And
Govner to Interactive.
Haven't got this tablet, just giving my 2 cents lol

No custom kernels yet so can't change any of those

Actually you can change governor, but it's already set to Interactive.
The values are fairly well tweaked too.
You can't change I/O scheduler though.

Oh, well either way, the lag remains. Out of curiosity how do you change the governor on stock kernel?

Use Dalvik
I switched over to ART immediately when i got the tablet, because my moto x runs faster on ART, but it lagged A LOT randomly, so i switched back to Dalvik and have noticed virtually no lag since then. Hopefully they can fix this in future updates...

The default camera creates corrupt jpgs and the sd card gets stuck in a loop. You have to delete those jpgs and all is well.

[Q] Moto G too aggressive about freeing memory - related to swappiness setting?

I have had my Moto G LTE xt1045 since they first came out and have been very happy with it except for this issue. It is very aggressive about suspending/killing apps. You notice this when you try to switch back and forth between two apps and find that it is restarting the other app instead of resuming it. It's especially noticeable when switching between a browser and another app. Another example is that I was using navigation and tried to use the NPR app to listen to some programs, but it would only do one or the other.
I realize that the phone only has 1 GB of memory, but it seems over-aggressive at freeing memory - doesn't it? I'd like to hear feedback from others about this.
In my searches for further information, it seems that one thing that can be tuned is swappiness. On my stock phone, the swappiness is set to 60. Have people experimented with different values?
My phone is not rooted yet as I've been reasonably happy with the stock experience. But I'm willing to root if it will allow a solution to this problem.
Thanks!

I was facing the same problem, I really hated that it closed the apps so aggressively. This was one of the main reasons I rooted. I don't know about swappiness, but there is a file: sys/module/lowmemorykiller/minfree which handles when the OS will kill different types of apps. If you root and download MinFreeManager you can easily edit this file. If you want more information on this topic, just search for "minfree" here on the forums. After using this app I've been happier with how memory is handled, but of course it is still only 1GB. Also it's worth mentioning that the values in the minfree file are reverted to default on boot. There are workarounds for that, event MinFreeManager has an "Apply on boot" setting, but it doesn't work for me. However it takes like 3 taps to set the values manually.
I hope I could help you.

This sounds like just what I need! What settings have you tried? Have you decided what works best on the moto G?
Thanks!

OK, I've been using MinFreeManager for a bit now and it has solved all my multitasking issues. I used this guide: Fine tuning the MinFree settings (improving on Android's multitasking) with the aggressive settings.

I confirm it works.

Just flashing the Franco kernel won't fix things?
Also the Android one phones with just 1gb memory performs a lot better at multitasking than G
Somebody with the skills should really look into how google is managing ram in that phone.
Seriously it multitasks like a dream.

No, the kernel is not the issue. It's a config file on the phone that tells android how much memory to keep free - if you follow the link in my previous post, you can read all about it and understand the issue.
It is a phone setting that Motorola changed in 4.4.4. With default settings, you will find that apps are killed by android when you switch to another app and the first app has to be restarted from scratch when you switch back to it. MinFreeManager fixes the issue - but you have to be rooted to use it. Your Android One just has less aggressive default minfree memory settings.

I see. Also one more thing I observed on Android One was that google play services was using 1/4th the ram it uses on my G . there was always 500 mb free ram

Rooting Lag Fix?

Hey! So I rooted, and everything went well. The only problem is the lag, I tried fixing it with Kernel Toolkit (the settings don't seem to stick?) and a cache wipe, but still have a lot of stutter. Any other ideas?
Thanks!

Root doesnt lag your phone, its impossible, root only gives you the admin permissions on Android. You must have some app that are killing your phone...

You should do some research before you say things you do not know about.
Root on the S7 US versions uses an engineering kernel that has the CPU governor set wrong and causes bad lag.
After rooting, download an app that allows you to adjust the governor like https://play.google.com/store/apps/details?id=com.grarak.kerneladiutor&hl=en
After allowing that app root access click the menu button and then select CPU.
Scroll down to the CPU Governor section and set it to ondemand or interactive.
I personally am using ondemand and have no problems.
Many people are reporting that this does not auto apply on boot as it should, so you will have to do this each time you reboot the phone, it only takes about 5 seconds.
Have fun with your newly rooted phone.

I repeat.. root doesnt lag phone.

Root access itself doesnt lag nor improve the performance of the phone.

Root access specifically does not, you're correct, but rooting THESE phones does cause lag because of the method we have to use. Rooting an S7 DOES cause lag.

God, some really sucky unhelpful people here.

Latest version of Set CPU?

Hello I'm looking for Set CPU but all links to Google Play Store appear to be broken, would like a reliable link for this app. Or is this app outdated? In that case would like suggestions for any other app for over locking of CPU. Bear in mind that I am new to the concept. Thanks in advance

Many Smart Pack kernel manager ( my favorite), FKM kernel manager , Ex Kernel manager .

This is a useless app made by Vietnamese people (I'm Vietnamese). It cannot overclock which many people mistakenly believe, and it only has the task of limiting the CPU speed, the CPU speed is managed by the OS and limiting it is a bad way because no matter what task it does it will be slowed down. When idle the CPU will automatically reduce its voltage and speed by OS. Any process no matter how big or small with high CPU speed it will be processed very fast even with small tasks that are reported not to use up CPU but it will still be faster than a slower CPU. Kernel Auditor is also useless.

SetCPU is only usefull if you have a modded kernel with added clocks (some of wich may be way to high for you device so need to be blocked to prevent crashes) and i used this version https://www.mobileapkfree.com/apk/setcpu-for-root-users IT MAY BE MODIFIED AND HAVE A VIRUS OR SOME **** so use at your own risk.
