This system_server creepiness... - Xperia Z5 Premium General

I'm not sure if this is what Sony is really doing to their stock ROM these days... They seem to put multiple service components that keeps system_server active all the time. Easily asks CPU to use 8~10% when doing almost any tasks.
Also one I'm not so sure of is how inefficient the CPU is driving the mediaplaybackservice. Is this Snapdragon 810 thing, or is this becoming more of an issue since marshmallow ROM updates...
Really eager to try non-stock based ROMs (Cyanogenmod or AOSP), but only if it weren't for camera problems...
What do you think? Are there workarounds to lower these services CPU usages? Or am I doing something wrong?

[Q] With rooting available, any benefit in running a custom rom?

This is such a unique advice given it's a micro console, insofar as when compared to other android devices.
But to maximize gaming performance, would there be a benefit of installing a custom rom?
Quick questions:
1) Like most android devices, does anyone know if this device comes under clocked (in the factory default sense)?
2) Would over clocking this device yield any benefits? hoping it would help smooth out N64 and PSX emulation.
3) Would it be wiser to just stick with the MOJO OS and just wait until an official update (kitkat) to root it? to install the over clocking apps, etc.
4) Is an update actually coming or is this wishful thinking on our parts?lol
Seems like there are so many possibilities for this neat little console. Hoping this device isn't too DOA given that they've priced themselves out of the market and the OUYA craze (whatever little fad it was) seems to be fading fast.
1. There are almost always benefits to custom ROMs....They usually are built for performance, and custom kernels make the world go 'round.
2. There is no problem with PSX emulation (FPSE is perfect on every game I've tried), and the problem with N64 emulation comes down to optimizing the app for the hardware....So I don't think overclocking would solve anything with N64. N64 games run the same on my old Tegra 2 as they do on my Tegra 3 as they do on my MOJO. It's not a fault of the hardware being inadequate.
3. Why wait for an update to root? There's always the chance you would lose root when updating, but there's an equal chance that you wouldn't be able to re-root after the update.
4. I imagine there will be at least one major update to KitKat...Possibly in Q2 or Q3.
For obvious reasons I can't talk to question 2 other than to strongly recommend that you don't overclock - indeed, it's worth repeating here that of course rooting your device does invalidate your warranty. Unlike a lot of Android devices which have battery performance to worry about, M.O.J.O. is not underclocked at all - as we're purely running from the mains there's no reason to do so and there's a massive heatsink in there to prevent thermal issues resulting in reduced performance too.
We are looking to provide an update to KitKat but we'll update on that as and when it's closer to realisation.
Things, you can do now to boost performance is, to set the governor from "interactive" to "performance" and set the min clock speed to 1800 MHz.
Brings some nice boost in benchmarks, but can't really say, that you get a real benefit in gaming.
I believe, that custom kernels and ROMs are not as easy as we think. You see, that even with the fastboot root method, there is no other way to reboot, as to unplug the cables.
So, that means, if I'm not wrong, that you can't temporarily boot/test custom kernels or recoveries.
But maybe someone will find a solution for this...

[Q] The best ROM for gaming

Hi guys,
first of all let me apologize for this stupid question. Personally I hate these questions too, but I have my device in service for 3 weeks, therefore I'm not able to continue with my research...
It's already a long time since I've bought my G2 (D802). Of course, the first thing what I've done > go to custom ROM ... (It's my habit since Xperia Arc S) I think that I was dissappointed of my new LG G2 even then. Games wasn't fluent and lagless as I supposed they should be. It was another good reason to go to the custom ROM. But unfortunatelly and surprisingly it was even worse. So I find another thing why is that so bad. In that time custom ROMS wasnť based on Kitkat sources (kernel), so I hoped that everything will be fine after developers merge source code. But the improvement has never become (in that form I hoped for) In that time I became reconciled that I will never play games on my G2 as smooth as on my iPad.
That's the reason why I'm looking for the best ROM for games. (I'm a heavy gamer)
So my question: Do you know any good rom for Gaming? Could you recommend me something?
I tried Mahdi. PA, Beanstalk, Slim ROM, CloudyStock, Pro, Flex, G3... But none of these ROMs is fine...
(I can't understand how can be Cloudy ROMs so popular (Nothing against Cloudyfa ) because they have too many lags in games !!! I think it's more laggier than stock...

What's the definition of "lagless" for you, and what games are you playing?
First of all, you have to realise and acknowledge that this is a smartphone. No matter what, it's still a phone and it's not made for heavy gaming. Second, you have to realise that despite the fact that many developers (ie Gameloft) has a lot of experience with games, they're too lazy too optimize them even for the most powerful chips out there. The games utilise 100% CPU speed even if they don't need it at all, and then the CPU throttles down because it's becoming too hot. Logic/10.
Thirdly, you have to realise that the ROM is not what makes the game fluid or lag-free. It's the kernel.
Since the G2 (like ALL other phones) is cooled passively (it has no fan whatsoever), it's important that it runs as cool as possible to prevent overheating and throttling.
My advice to you would be the following:
Install your favourite ROM and a kernel you can tweak heavily (gpu/cpu). A good bet would be dorimanx.
Go to kernel settings, and chance max frequency to 1.27 Ghz or around that. Change governor to performance.
Change GPU to 450 Mhz.
Try playing a game =)
I used to play Asphalt 8 back when I first got the phone and I got about 30 FPS? Anyway it was smooth as butter, and I see no real reason why you want to put a custom rom on your phone. The good 'ol days where nothing was better than custom roms are pretty much over. Stock is just fine, root it, use a custom kernel if neccessary and use xposed. Will solve it.

Of course that kernel is the most important thing in performance (because of sequencer laws, etc...), but nowadays we have no (except render) custom kernels for AOSP/ CM ROMs, so my question was focused on a ROM → I connected it to the whole... (And furthermore each ROM has own kernel. + ROM can cause lags as well)

Unfortunately these times are gone, at least I think it. There were lots of updates, which increase the performance consumption (Simply they add tons of new features and stuff, but they ,,forget" to optimize that... ) I played this game, Dead trigger 2, Dungeon Hunter 4 and even simple games like traffic racer with incredibly high count of lags (And it wasn't lags in miliseconds → not always). I thought it was because of my current ROM (Mahdi) so I tried PA and then stock based ROMs (CloudyFlex, Stock) but nearly no changes) Therefore I think it will be the same on stock ROMs too, if it's on Cloudy ROM with heavily optimized kernel, system... (Even Dorimanx kernel doesn't change anything).

Thanks for this tip, I tried something similar but with UC to 1,9 GHz and I didn't set governor to performance (My device was incredibly hot in a while with performance governor), I didn't notice any bigger changes - I expected that lower frequency will cause even more lags and I was obviously wrong. For sure I will try your advice.... :laugh:

I don't like the LG's design of system, and I don't like xposed → it causes higher battery consumption and it ,,eats" RAM and performance (At least on my previous device )
i have 10 xposed modules installed and i didn't notice any additional battery decrease...
as for ram, as stated many times - free ram = wasted ram...
as for the thread - "what's the best this&that" threads aren't allowed on xda
i played rr3 and csr racing on this device and didn't notice anything wrong with the framerate (stock kk v20f, rooted with dorimanx kernel on default)
Oddly enough, I haven't noticed a major change in gaming performance coming from the S4 Pro. Asphalt 8 specifically is buggy, sluggish, etc on my LG OG & G2, but I don't care for android gaming since the apps aren't optimized (too many HW configs, whereas iOS is just SGX & Ax chips).

First of all, I like to say that we lacked similar threads, so OP started an useful topic. I would have stayed with simple dual-core smartphone, but I bought G2 in November for a reason, to try new games and so on, I woudn't have bought it if I needed a phone only for texting and browsing, like many argue like this. What I observed is that, 2,3 Ghz for a phone with passive cooling is a nonsense because after few minutes of gaming it will keep running like 1,5 Ghz and lower, hell what's the use of those 4 cores if a device would burn out. I never owned an apple product, but on my colleague's 5S, they run very smooth and fast with same graphics on a dual-core, so it all goes to optimazing and not using these ridiculous frequencies. I was expecting a lot from a phone like that, sorry for a long post.

[Q] What causes S-Lag?

We all know what I'm talking about.
Have a Galaxy Nope 3 (N9005), stock ROM, go, for example, in Settings -> Connections, and scroll up and down. Chance is, you will see it stutter.
After flashing a multitude of ROMs, AOSP and TW based, I find the stock one most stable, so right now I'm stock, rooted and Wanam-ed.
What exactly causes the legendary S-Lag which causes a device with a quad core 2.3 gHz processor to stutter, and can it be removed without rendering the ROM unstable?
A bad rom or kernel causes it. Tested it out on MultiX 1.5 with kk-Xplorer 1.6 kernel and I dont have it. Then again, i tweaked my kernel and rom to my liking, if you just mass install everything, you will get lag.
Zero lag here, xxuend3, stock kernel, some apps, games disable from startup with android tuner.
Note 3 rooted knox 0, bootloader locked, my last Samsuck crap. I want freedom.

Legendary S-Lag = TouchWiz.
On AOSP no ROMs lagged for me, and I tried practically all ROMs available. The worst case are RR's..
On TW based ROMs, a bad experience means a bad governor from your kernel, for your device. Meaning that your device has a specific governor it likes, and to adjust this use Trickster Mod Kernel Settings available on the Play Store. Also heat dispersion and the kernels ability to scale frequency under high amount of load may cause problems, as the higher heat (theoretically more load) hence stutter and graphical latency.
All clean, stock, custom ROMs play nice because they removed a lot of Samsung's default list of S-Apps, which does free up process load on the RAM and processor. As said before TouchWiz plays a big part in lag, however I'm not saying it's not good. The S5 ports all are great but that's because people actually spend the time recompiling broken/useless code from Samsung's source code. Alexndr is a good example - where he started from 0 to 100 recompiling literally all of Samsung's permissions.
This is why people like debloated ROMs.

N5X Overclocking Thread

Hi guys
Who has his device overlclocked? I installed on my N5X the TWRP and the ElementalX kernel (no root) due to the bad performance in trottling with stock kernel. In this moment I have a little overclock on the A53 cluster, I'm at 1536/1833 and it runs fine, I think that the critical point of the 808 is the A53 cluster, someone use it @ 1600MHz?
I'm looking to overclock it as well
Any ideas are welcome.
I think that overclocking the little cluster the device in little task may can use a little less the big cluster and save a little the battery Life. Antone tryed?
I know this thread is 2 years old, and I shouldn't be reviving it... I just had it. Current Nexus 5X with crDroid (which seem to be faster than stock Android) is performing like garbage. Battery and performance in general was greatly improved when I turned off background activity for a lot of 8.x unsupported apps (You can check them in the battery settings)... But it's just unbearable. Everything takes a long time to load.
I don't use anything fancy. Maps, YouTube, Chrome, WhatsApp, Keep, a couple applications now and there, and there's still free RAM. Since I've read that this one has the more powerful CPU turned off, except for demanding tasks as games, I thought some overclocking could make it work better. I'd like to push this boy as far as possible (I make myself proud when I do that), and I'm going to be overclocking it...

Note 4 Exynos (910C) - Which Marshmallow custom kernel allows CPU OC? (to 2,1-2,2ghz)

So I want to OC my phone a bit.
That's my only gripe with this device, that it's a tad bit slow - I think due to the high resolution.
Back in the past I used OC on my Note 2 and S3, and both became blazing fast.
I realize you cannot push a chip on 2,2ghz all day long.
But that extra boost is extra handy when you do need the speed.
I checked out the kernel forum of course, but I only found a GPU OC kernel, and one kernel with only a 2.0ghz OC.
That's only 0.1 ghz increment, that ain't not much.
Ps.: I realize that not every chip is the same. They all have different undervolting/overclocking capabilities, it's silicon lottery. But I do want to see if I could push my Note 4 a bit. And heck, it will throttle anyway if things get a bit hot.
And of course another post about someone wanting to control their cpu and nobody on these forums gives you an answer, I have been trying to look for solutions and kernals that offer cpu overclocking to atleast 3000mhz like how cm13 is, The problem is I dont like the ui of cm13 and want to use rooted jasmine which is based on stock 6.0.1 , but the cpu on apps only lets me clock it to 2649mhz and it doesnt let me set frequencies at all sometimes, it seems nobody knows or cares to tell anyone if their roms support cpu tuning or not, its sad and annoying because people seem to get their useless questions answered and not issues of this kind which are why some people even decided to root in the first place, like me.
Did u checked the Nemesis and Refined ROM threads from the exynos forum? There you can find what you want.
Here you can find and learn if you have a time and will to know and learn every possible things about Cpu ,setting up Cpu ,frequency and other stuff:
