Game tuner stuttering. - Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot

Guys I have this problem since I have updated to 6.0 in september 2016. I have the galaxy a5 2016 exynos version. Basicaly when games are set to be controlled in game tuner ( from game category) in 1080p or even 720p they lag like hell ( and I mean 15 fps !!!!) But when same games are set to non-game category ( they default to 1080p) they don't lag they have 40-30 fps. And I want to know if this will be fixed because HW performance doesn't do anything! I have android 7.0 official rom from samsung with may security patch build. Seriosly no one is talking about this and people keep telling me that I have a fake phone! ALSO after 6.0 update 1080p 60fps youtube is off. Only 720p 60fps is available. Any advice?? Pls! games are getting more demanding and 1080p is too much for this phone. And I don't have money to buy note 8 or iphone 10!

SIOP_ARM_MAX?
Doubt this will be 'fixed', seems to be working as intended. Maybe there's a list of always non-game apps in /system/framework/oat/arm/services.odex. It works for you, simply set game apps to non game. You'll still be able to change the resolution of non-games in the game tuner. If you really want an alternative, it requires root.
Code:
su
chmod 644 /sys/power/cpufreq_max_limit
chmod 644 /sys/class/misc/mali0/device/dvfs_max_lock
Set permissions of those files to 644, owner read write, group read, others read. If it doesn't work set the group to nobody or somehow deny access to this file. You must monitor temperatures of the device, use at your own risk.
If
Code:
cat /sys/class/thermal/cooling_device0/cur_state
cat /sys/class/thermal/cooling_device1/cur_state
cat /sys/class/thermal/cooling_device2/cur_state
remains 0 under high temperatures, the setting is not done correctly.
/sys/class/misc/mali0/device/dvfs_max_lock_status. First column is the step wise thermal throttling governor (cooling_device), the 2nd is SIOP_ARM_MAX or something else.
Search SIOP_ARM_MAX;limitCPUFreq;limitGPUFreq in the logcat when the FPS drops.
Lower the CPU or GPU clock in those files (dvfs_max_lock, cpufreq_max_limit) or disable touchboost if the device gets too hot. Warm is OK.
Those files will reset after a restart(reboot)

Thank you so much for reply and I don't care about rooting. Well it seems like I can still lower resolution in non game category but game tools unavailable. I don't use it anyway... I don't understand why samsung doesn't care about this... Is this problem on galaxy a5 2017/s6/s7/s8 as well? Anyway ty for the fix.

It indeed seems to be applied on Samsung devices with updates past 6.0(search siop_arm_max to get logcats), S8 appears to be included. Source
The game tuner lost HW performance because people were complaining about the heat, that's what I remember from its changelog. It's added again.
That device "galaxy a5 2016 exynos version" does not fail once those settings deviate from stock and heavy games are ran (maybe it could if the heat is somehow trapped, but maybe it will just trigger the swelling protection) but it could reduce the life expectancy of various components, at least the battery.
Finally, maybe the game limit is meant to reduce power consumption.

[Q] Fixing bad 3d performance?

Hello,
So it seems the Note 4 is not that good at 3d performance in quiet a few games, especially Grand Theft Auto 3 (atleast with snapdragon 805, not sure about the other chip they use). I presume this is because it renders at the screens native resolution, and that the snapdragon 805 is not good enough for that.
If that be the case, is it possible to force game applications to render at a lower resolution, thus making the game less jittery? I have root.
In anomaly 2 it quite good
Maybe you shouldnt use power saving mode when play these heavy 3d game

Ive come to the conclusion that thermal throttling is to blame. I haven't play a heavy 3d game without it dropping frames within 10 minutes. It an issue that needs to be addressed.
I've been able to play modern combat 5 and dead effect without any slowdowns. Exynos Note 4.

There is an app to reduce the screen resolution:

It does require root. Unfortunately I have att version and no root yet. Wish I could use this, as some of the higher end games don't run great at 1440p.

Seems to work with improving performance in the brief time I spent testing it, but it messes up the UI on a things, such is expected.

Thats correct bro, i came from S5 SD 801 and vice city (wich is more heavy than gta3) run smooth until i hit 20 mins and begins to slowdown.
I dont know at what resolution runs GTA VC on note 4 but i maxed out all settings and is super fluid and no slow downs, i being playin for 30 minutes and the smooth its not gone so far.
exynos variant.
I also have noticed some problems with Real Racing 3 and 3d Mark bench. Not as smooth as I've expected. Also on AnTuTu I get 40-49k one or two times even below 38k results so I think there is some thing we don't know about our device. I hope when Lolipop arrives this problems will be solved.
thats terrible for a 800$~ phone ! mine does excellent job on dead trigger 2 and nova 3 and riptide ! i have the exynos verison. i just got it i haven't downloaded any more games but im downloading order and chaos and dungeon hunter !

Poor gaming performance - Galaxy Note 4

Hey all.
So I would expect a 500 quid phone to be able to play the latest and greatest mobile games without stutter. Unfortunately this is not the case, with my most recent example being Real Racing 3. This game has terrible stutter and a frame rate of maybe 20fps if i am lucky.
I suspect this is partly to do with screen resolution, however is there a way to actually make the Galaxy Note 4 a good gaming device? I have root.
@captainbirdseye86 Lower the screen resolution with nomone apk from google play there is a thread about it here http://forum.xda-developers.com/note-4/help/downscale-resolution-to-1080p-to-t2886177 and the apk link is here https://play.google.com/store/apps/...=nomone&pcampaignid=APPU_6l3OVKeSLZPaav6hgdAK also try to disable dvfs with xposed framework install a custom kernel (more performance depending on your settings but also more battery drain) and try to have a stock ROM as much as possible yeah all those customized Roms are way better but nothing is perfect all those mods costs on the performance also greenify your apps and system apps as much as you can...just some tips

Good work man. I'll just add closing background apps and messing with the minimum/maximum GPU/CPU clock.

it is very disappointing indeed .. I rarely play games, but Asphalt 8 is my favourite and it is just unplayable on my sd805 note 4.
I have paid £587 for the device, and apparently have to root it and spend hours if not days tweaking it to be able to play some games.. Not a good job from Samsung in this department ...

The answer to all your performance problems is a clean bug free pure google ROM I don't know if you can install one on the SD since I have the octa one but a ROM without all those s crap and bloatware equals to more performance if the ROM of course is properly cooked

I heard a dev talk that there isn't much to be gained by ocing the GPU and as far as CPU oc goes the more you push it the less time it will stay on that frequency because overheating could be 5 minutes away at full throttle oh and if you oc the GPU keep in mind that some voltage tuning might be necessary on the octa one I had stuttering on ultimate and persues kernels it varies from device to device...

The answer to the problems... its partly the chip runs so hot.. wait for lollipop to see what happens 1st

If you encounter problems with GPU OC, just increase the voltage a little bit. Don't see a problem there. When I talk about GPU/CPU management I mean mainly to increase the minimum GPU clock as some games don't demand enough of our device (haven't tested). Even with DVFS disabled I get a lot of 20ish fps playing spider man unlimited and the phone isn't even warm. It means the game is not requesting enough power. This is something I want to test, to force a high GPU clock with DVFS disabled and see what happens, but there's no kernel able to do that on exynos yet. Have you tested this? Do you know a way to control GPU clock on exynos or do you think they'll ever implement it?

It is very unfortunate to say that every smatphone in the world is like this. I'm a fan of asphalt 8 myself so I can say about it. I was playing the game on my girlfriend's iphone 6 which has the best GPU on a smartphone in my opinion + 750p resolution = insane graphics performance, right?? Sure! IF you don't throttle like crazy. Even with this insane combination the game hits 20ish fps here and there while the phone barely gets warm.
If you want to play the game with high fps without rooting just lower the graphics in options -> display. I was playing on high after all the mods I've done but it gets so hot and the battery runs out SO FAST that now I'm just playing on low/very low. The quality difference is minimum and you can play for a looong time.
If you need help to tweak your device (after root) for playing you can PM me. I'm a high fps addicted.
Hit the thanks button if I helped.
i am not sure why the games you are playing got low fps, i have played many games including BIA3, NFS MW , Dead Trigger 2 , BatMan, MC3 , Asphalt 8 etc
I so far felt no stuttering or any slowness even no Hot device over my Exynos
I am on stock No Root

You live in a cold place? Don't play for long periods? Many games run perfect on complete stock, sure! It isn't that bad.
@gabrielgon thank you for your time explaining this so yeah I get stuttering on God of fire let's say I will have to increase the gpu voltages table by at least 50 to make the problem ALMOST disappear now about low fps yeah also on galaxy on fire when a ship explodes I get some fps drop it is quite hilarious really thinking that this monster reaches out it's limits after some brainstorming though I figured I should reduce the resolution to 1080p or even 720 and woala no fps drops although the stuttering is still there so I guess I will have to increase the gpu frequency although I don't know if there is a way to do this...I will try to search a little
EDIT: OK so I used two apps that let you control the gpu frequency but it won't work on one app the function was greased out and on the other I kept pushing the button but it never took me to the menu to change the gpu frequency my guess is since the kernel doesn't support neither will the apps I don't think we will find any out there to do it if the kernel doesn't support it...

Ok, some stuff I can help you with:
Increasing the voltage doesn't increase performance, this only makes your phone use more energy. People usually undervolt their phones to get better battery life but when it gets too undervolted the phone gets unstable. That's why when you overclock you might need to increase the voltage, to keep it stable.
You won't be able to mess with GPU frequency unless your kernel support it. Maybe if you are a snapdragon user (I'm not sure), but on exynos you won't.
Downscaling resolution helps. There's a thread about it here. Good luck!

That's probably the battery temperature, but either way that's pretty dam good!! After 10-15 minutes you'll probably reach the heat peak already so that's enough for testing. Good to know you're having a good experience!

Thank you gabrielgon, note 4 is the first galaxy phone I am reluctant to root. I just don't have the time I had years ago.
I kind of disagree with you that all phones experience these issues. My previous note 1, 2 and 3 had no such problems.
That is just new to me. With all my previous note phones, I could just download any game (most likely asphalt ) and play as long as I want.
It is annoying that my note 3 (which I still keep) is capable of playing Asphalt 8 on max settings for hours with absolutely no issues and yet my shiny new note 4 just struggling with that.
I think samsung just should not have adopted the 2k display technology so early. Obviously the hardware is not there yet.
I personally do no see any difference pixel wise from the display in my note 3.
Yes, the note 4 has brighter and more accurate colour wise display and that is all they should have change.

that is cool man. I played with 3 note 4 (returned the first 2 because of defective displays and overheating) and they all had this issue.
It is not that I dont believe you, but I have to see it to believe it
My experience on the Note 4 is virtually the same as my experience on the Note 2, a device which is over two years old!
I do prefer Exynos, but I purchased the Snapdragon because it is the most supported SoC on the market, for now.
I'll make sure my next device sports an Exynos, I miss my Wolfson and Noticeable Performance Boosts, overall, going from one Exynos generation to the other.

CPU Throttling - warranty?

Hello !
After long weeks of searching the answer and solution to my problem, I am exhausted. So I would like to ask the biggest Android community for help
Well, I know it's not new, but I have problem with my S7 Edge (Exynos) performance
I experience FPS drops in almost every game I play. As for games it's not that irritating, but recently I have bought Gear VR and while having this thing so close to your eyes, you see every frame skipping.
Apps for checking the CPU throttling shows that after 5-10 minutes the 4 bigger cores slow down to about 50% of their full speed. It leads to ~30% performance slow down.
I tried every solution that doesn't require root access and warranty void. For example: disabling certain packages and services (Game Launcher, Game optimization service); different settings in Game Tuner; performance mode; factory reset etc. Nothing works.
Does this kind of problems can be repaired on warranty? I know that in order to fix this you can change kernel setting, cpu governor etc but ofc they don't do that in Samsung Service Center. Is it possible for them to replace the main board and cpu with Snapdragon one?
I would not like to root my device because I didn't want to lose my 3 years warranty and I am using a lot of applications that may not work with a root.
Thank you in advance for all your replies
Did you try the game performance mode? As the "performance mode" is just screen resolution and brightness. The game mode is the real performance mode where the temps throttling is relaxed and higher clock speeds allowed(you can also edit the profile to set the resolution manually to wqhd). You can also try to set the resolution to full hd and see how it goes (tho for VR it won't be cool, but for the test it won't hurt). Also if the phone is new, it will need atleast 10 days to settle and become faster, smoother, better. Apply updates if they are pending too.
Otherwise you can't do much without root, but even then you are limited to what you can achieve so be careful + samsung have a fuse into the chip that burns out when you root the phone, it's not possible to hide the intervention and they can deny warranty for that reason (and often do so).

Yes, I've tried "game mode" but there is no difference. Changing resolution to Full HD helps for a while, but the Gear VR software doesn't work properly on anything other than WQHD. It just doesn't scale properly and you are unable to see whole content.
I'm just wondering whether every S7 Edge has problems like mine. I understand throttling after 20-30 minutes of intensive gameplay, but ~40% slow down after 3-5 minutes seems strange, especially because phone doesn't even get warm.

Hard to tell, got the phone, but no vr... :/
Otherwise I don't have problems with gaming, the game mode smooths a little the already fluid gaming(but then again, the game I play mostly is vainglory and that game runs great on htc m8 that is almost 4 years old). You are talking about some more massive performance drop. Many phones start to throttle early and throttle hard, samsung is one of them for sure (they want the phone cold).
@hamdir can you lend a hand on that one? You are tons more experience with VR than me.

Well, there is an app called CPU Throttling Test on Google Play. I would be really thankful if you give me information how your phone behave in this app. Mine throttles hard after 3-8 minutes. Clock speed of the better cores goes down to about 1.6GHz each. Sometimes even below 1.5GHz.

From a cold phone, 1.9GHz almost right away(I guess the highest freq is only for burst load, like app launching) and kept for 8 minutes then drop to 1.57GHz on the big cores. So I think it's in line with your result.

Yeah, that would be it. Thank you for your time. So it seems to be normal, I hope I'll get used to it somehow
I also wrote an email to Oculus, maybe they heard sth about this issue and know a fix for frames skipping.
The notorious feature known as DVFS is the likely culprit. Some forum members suggest it throttles the GPU and CPU to improve benchmark results or otherwise to protect the device. I've noticed it can lock-up and end up overheating the device but that's just an anecdote.
You can try forcing the app to run at a lower resolution which Samsung's Game Tuner does for some games, or find other solutions for unrooted devices like capping CPU frequency for a smoother experience.

Almost all the phones are tweaked to use max freq only on single core load and app startup (burst). If their power management detect heavy load on all cores, it will automatically scale down to lower freq state to prevent heat building up fast. In reality in our case this is 1.87GHz for all big cores + the small ones (higher if only the big cluster is used, leaving the small cores off). The first actual thermal throttling level is 1.56-1.57GHz at around 8 minutes mark. Games would take a lot longer and in my observation as the phone is big and none will use 8 cores at the same time - there will be no throttling, just power management and stable fps. His case is different tho, VR is really a heavy one on the CPU.
As for DVFS (and extended to samsung power management, every manufacturer has it's own management) - it's there for a reason, to use your phone without major slowdowns due to heat and to be cold in touch, i.e. better for use. You can always change the behaviour via custom kernel, but you can't get more performance without heating the phone to the point of hardware throttling or uncomfortable to hold. Actually as you said - the right way if modify is to cap to lower freq and try to command the phone to keep them. This would still lead to a lot of heat, but will take some time to build up (and it will look smoother, tho with lower fps). OC is pointless for speed gains, will work only for burst loads. UV is not effective too as nowdays the SOC's are heavily binned for optimal settings from the factory.

Game Lagging (A7 2016) (SM-A710FD)

Hello guys..
I have this phone which has a quite good Specs..Though when I install a game, there's some lag
I'm running on Nougat 7.0, I've installed asphalt 8 and there's a lot of lag in the main menu, but that doesn't matter cause I deleted it
now I've installed PUBG Mobile and it's a very exciting game and I'm running on the lowest graphics and I have free ram and space But it lags a lot. I've tried this game on Galaxy A5 2017 on medium (balanced) Graphics and It runs like a charm.
Is there anything I can do to make the game on my device faster with no lag? And why does the game lags anyway on my device which has 3GB Ram?
It's not the RAM that matters but also the GPU. A 2016 uses Mali-T720 while A 2017 is Mali-T830, thats the difference.
I suggest you use Game Tuner from Samsung and adjust the resolution to 55-80%
OK, the hardware is different, but other than that...
A 2016 (info from A5 but should be close) That GPU should be enough to fit the first game on high (maybe outdated), and the second on low (untested). For context, the CPU/GPU is like a motor, running at various speeds, 'weights it is carrying', and power required to maintain that speed (the heat output also scales with this). Some are simply better than others. The Game Tuner's HW performance (CPU) isn't or wasn't available. The customfrequencymanagerservice lowers the CPU/GPU speed for games, also increasing the battery life and lowering the heat. Search the logcat for "limitGPUFreq" "limitCPUFreq" "SIOP_ARM_MAX" (not the tag, but the content). Other than that, the CPU cluster 0/CPU cluster 1/GPU lowers its own speed at 86c (not bidirectional). Optionally, at the cost of heat and battery life, downgrade the game tuner and game optimizing service to whichever version has the apps category feature. Then select the app, then non-game. Lower the resolution to the default 75%. A limit is still there but not as much as before, and looks more like thermal throttling. If rooted, the max speed can be customized in /sys/power/cpufreq_max_limit for the CPU, and /sys/class/misc/mali0/device/dvfs_max_lock for the GPU. Set permissions to 644 to maintain the max speed (until the CPU/GPU lowers itself). Watch the temperatures. If it's too hot, reduce the limit. Maybe an alternative to root is debloating but the speed can't be lowered if needed.
Temperature sensors are here:
/sys/class/hwmon/hwmon0/device/temperature
/sys/class/power_supply/battery/batt_temp
/sys/class/power_supply/battery/chg_temp
/sys/class/thermal/thermal_zone0/cdev0/type
/sys/class/thermal/thermal_zone1/cdev0/type
/sys/class/thermal/thermal_zone2/cdev0/type
/sys/class/thermal/thermal_zone0/temp
/sys/class/thermal/thermal_zone1/temp
/sys/class/thermal/thermal_zone2/temp
etc.
A 2017
The customfrequencymanagerservice applies to the CPU, up to 1794Mhz (HW performance). May lower with what looks like thermal throttling.
Does not apply to the GPU, which throttles itself somewhere around 76c from 962MHz to 845MHz.
Yep. Been playing PUBG Mobile on my A5 2016 on LOW graphics and HIGH frame rate (fps setting) for around one month and it does NOT lag. Although the transitions in UI of main menu is not as fast but the gameplay is super smooth and does not lag. Maybe it's because of your phone slowdown over time (I just factory reset my phone 6 months ago) or because the A7 has more pixels to push so it is more taxing on the GPU.

I tried to set a game to a *non game* but game tuner doesnt let you switch anymore between them
I have A3 2016 and playing 20fps in game. ( Medium fps setting). If i select high frame rate my phone is heating much then my display doesn't work stable its sensitivity sucks when phone heats. It's not lagging to the last 3 circle. But if i see an enemy my device lags a lot and my fps drops 5-10 so i died more times bcz of the fps drop. Gameplay is best in Lineage Os 15.1 but it has overheating issue so display sucks when device is overheated.

Downgrade. I have Game Tuner 3.3.03 & Game Optimizing Service 1.1.89.0, and it's there.
Edit: Game Tools 1.2.48.3, Game Launcher 3.1.00.5.

The game optimizing service was downgraded? Reset (data for that app?)? The auto updates in the Samsung Store are forbidden? Else, maybe downgrade it further...

Yes it was. App unistalled multiple times. Samsung store removed entirely. Downgraded already to the lowest. The point is that some time ago i was able to do that, now it just wont work

PUBG Mobile and Samsung S8

I've been playing PUBG Mobile for a while now and wanted to ask you how you find the performance on our Samsung S8.
When I had Android Nougat it really sucked (a problem that shouldn't happen, because of the great potential of our phone). However, now that I have Android Oreo I can play normally and without problems, but I still find that I should run better because I have seen it installed in cell phones of lower capacity and have more fluidity.
Someone who plays it and knows some trick to get 100% potential out of our S8?.

check what's running in the background that may cause hickup, look out for memory usage
I have an S8+ with the google wiz rom (It erased about 300 apps and has some optimizations) and I still feeling that my phone doesn't run the game as fluid as it should be
mine S8+ still has nugget. haven't received update yet. all the other apps and games run fine except PUBG, it freezes then restarts.
Mine s8 doesn't support hdr graphics and ultra frame rates in pubg
Hello
I have an s8 with custom pie ( hades rom ), max setting are hd and high fram rate, while rooting and removing all bloatware etc...
Just download gfx tools there is a paid and free version, i played it on smooth graphics 60 fps no lag at all, remember that internet speed plays a big role.
Hi, I know this is super late but what I've found about gaming on the s8 is that there is absolutely nothing that will affect the performance of the phone or your experience of the game more than thermal throttling. I tried for weeks to fix my lag problems with all kinds of kernel tweaks, network teaks, getting rid of background processes and trying to keep my ram free and was totally stumped until I realized just how much my cpu was being supressed by thermal throttling. Download GameBench to get an overlay of your in game frames per second (you should be able to get a constant 60 fps no problem until the throttling sets in) and get Simple System Monitor to monitor your thermal sensors and cpu frequencies. You should start to see an immediate correlation between your fps drops and your and clock speeds and temperatures. If your phone is rooted you can use Kernel Adiutor to set your cpu govoner to performance (it just locks your cpu at max clockspeed). This will make the throtting very easy to see in simple system monitor because you can see how your max clock speed is gradually stepped down as thermal engine overrides the govoner.
Now for the fix. If your S8 is a exynos you are a lucky b***ard and you can probably find a software solution for disabling thermal throttling like with a custom kernel or by editing a few system files. If your stuck with a locked bootloader like I am on the snapdragon s8 than the only solution is to actually keep your phone cool while gaming. I use ice packs wrapped in a paper towel. They only last about 30-40 mins so you may need several ice packs and keep them in rotation. Whatever cooling solution you use just make sure its not too extreme or too sudden as rapid changes in temperature are not great for electronics. That's why I use a paper towel as a bit of a buffer between the phone and the ice pack. Works great for me and I maintain 60 fps all game.
