Hi,
I have a p6210 running a rooted stock odexed ICS 4.0.4 UELPC (us XARLPC).
My first problem is that the device lags and stutts when I navigate between the menus like for exemple the apps drawers or the control panel, or when I scroll.
It seems to come from the hw acceleration since it lags as well when I watch videos (on both audio and video) and the only way to overcome this is to use mx player with sw audio and sw video settings.
I tried to tweak my build.prop with various values, enable hw acceleration, force gpu etc. but nope, it still lags and actually it gets worse so I went back to the default values.
I tried as well in the dev. options in the tab settings to force gpu but no results either.
The second issue is battery drain, my once long lasting tab has seen is autonomy reduced by approx. 50%, not nice.
The third issue, that might be related to the second, is that the tab heats more than it did previously.
Any idea or help will be highly appreciated, thanks in advance!
Well i didn't experienced this in my galaxy tab plus. Im using a stock 4.0.4 without root. Im not into rooting anymore because i experience bricked and some hack problems when root.

I didn't experience such problems either. Did you delete/modify anything in system after rooting? Just rooting can not not harm your phone/tablet.
I deleted the gapps plus all the samsung bloatware but I don't think it's what causes the lags.
I deleted as well some permissions, lib and framework files like facelock recognition, network locator, google maps, minimode etc. but I have put them back and it still lags.
I think it's a hw acceleration problem, and I have seen elsewhere on the net that I'm not the only one experiencing such problem, other people complain as well about video and hw acceleration on games to have hickups.
When I tweaked my build prop to enable hw then it got worse, and the only way to have videos running without too many lags is to use sw decoding.
The same with mp3s, I had to enable audio buffer and audio thread priority, otherwise it skips like hell.
When I compare with my galaxy mini, whose specs are far lower but where everything is smooth, it's like day and night, even scrolling on the tab has hickups.
I may try v6 supercharger, but I'm not very confident about it since I used it on my galaxy mini without any noticeable effects...

Hey there, its been bothering me.
When I play games, such like asphalt, batman, and subway surfer, the tab get heated after wuite a long time. About more than 20+ minutes.
But when i am using stock browser or dolphin browser, the tab get heated much faster.
Anyone know why does this happens? Does thisnmean that browsers use more CPU compared to games(asphalt uses internet too, also scrabble).
Please and thank you!

This might be incredibly stupid, but does anyone know if it's possible to have your phone deep sleep while playing music through headphones? Because it sticks at min freq and kinda eats up battery, regardless of governor or I/O

Sry to unearth that thread, but i had the same question and didn't found an answer here on xda - so i checked it myself.
And the answer is yes, it is possible, but to my knowledge there aren't many music players that support this.
If the sceen is off they buffer the blayback and let the CPU go to sleep and occasionally wake it up to rebuffer.
CPU is in deep sleep for 60..80+ % of the time.
Music players that let the cpu deep sleep (to my knowledge):
- clean music player
- es player (part of es file explorer)
Music players that idle at min frequency or higher and dont allow deep sleep:
google music player, playerpro, neutron, shuttle, nexmusic, n7player, poweramp
I've checked the deep sleep behavior of the above mentioned players with CPU Spy v0.40 on Stock Nexus 5.
The downside is that costum Kernels can cause the playback to stutter, just stop and/or other things.
I don't know exactly why but my quess is that happens because of a too low frequency in the time the cpu is awake - to raise that may help.
Or its maybe because of too agressive governors that force the cpu to early back to deep sleep.
It would be interesting to see if anyone else had made similar observations, found other music players that support deep sleep of the cpu.

Hi,
The solution is to stop the media player after a certain time. If you want to sleep with music we have a tool that allows you to set the duration for the player and a gradual reduction of volume at the end. So it will stop the player and let the phone to go to deep sleep mode

The goal is not to go to sleep while hearing music and stopping the music when you are asleep.
The goal is that the music is playing while the cpu of your phone can go to the "deep sleep"-state and in consequence to save battery while playing music.

I understand that but what i mean is that playing music needs cpu to run in normal mode, I don't think that it's possible with android coding and i think that you don't have to worry about that as your screen will go off after a certain time and as you know the screen is consuming more than 95%
That was also my thought ... But some player like the above mentioned display this behavior of letting the cpu go into deep sleep state on nexus 5 with android 4.4. The playback works fine for a while but then just stops and/or crashes utterly. Seems to be a bug with the new android but non the less the playback works for a while (up to 5 to 10 min)
The CPU is for 50 to 75 % of the time in deep sleep
Would be interesting to see an player who can make usage of that behavior/bug. There is always need for more battery life

That's right but I don't think that as app developers, we have that control. All what we can use is wake lock to wake up the device partially or fully when it's locked or to keep screen on, but for media player it's handled by the system so I think that this optimization is done by mobile constructors. You can use batterystats app to keep track of wake locks to detect big consumers and stop them (or remove them) to keep your battery charged for long

I'd like to bump this thread. I'm REALLY interested in such music player that would allow deep sleep during playbackplayback. We now have high memory devices, some with whooping 4gb of ram that could hold the entire library of most casual users. I really do hope there actually is a player that would simply load like 20 tracks that are in the Playlist to ram and then simply let it go with minimal cpu usage thus hopefully allowing for deep sleep. I did see a something interesting on my windows pc. Few years ago, when I started using foobar2000 I got a BSOD, irrelevant to the player, but I was listening to music and after a BSOD it actually kept playing for quite long even though the os was on halt completely. Thanks to the long 30s buffer I set in foobar2000.
I think this concept COULD actually work on our android devices. Please do correct me if I'm wrong. If there's already such player then please post a link. I'll be glad to try it. I'm a music addict so that would help me.
I did try clean music player, but I couldn't find a way to play all tracks from one directory including it's subdirectories. All I care about is shuffle all tracks from one directory including it's subdirectories and of course ability to use a equalizer.

Second bump. I would definitely agree with the need of an app like this*! Has anyone found anything?

I haven't heard about any. I've had an idea of loading tracks in playlists into a single long track, then loading them to ram and that might allow to play them without waking the device, but that requires a certain level of skill.
Worth bumping up in 2022?
Maybe?
(Also looking if this can be solved for Spotify on bluetooth headphones).
I don't know why this excellent feature didn't get widespread acceptance. Other than Nexus 5, I only know the Xiaomi Redmi 3s which supported this feature that too only in Android 6 (stock MIUI and LOS 13). In all the Android versions till A12 which I have used it didn't work.
P.S. Unrelated but Xiaomi Redmi Note 10 Pro and Poco F4 can enter Deep Sleep while serving as a hotspot, at least in MIUI, but not during audio playback
I am experiencing some - a little bit annoying - bugs in music playing, and i hope someone could help me..
I am using stock rom, phone is rooted.
Actually I am using poweramp as main music player (which the better one for solving part of my issues) with the following sound andvanced settings:
-no dvc
- buffer size +750
-Thread Audio: Maximal
and music still stutters everytime my phone locks the screen or randomly every 2-3 minutes (i don't know the exact name of the problem, but it's the same as when you're listening to streaming music and it has some buffer problems, it stops for a nanosecond, but you can clearly hear it)
I tried also different options, as it looks like it could be a ram processing problem, by disabling all unnecessary applications i didn't use, sense included (Using Apex right now). Disabling beats doesn't change a lot (and I bought this phone also because of Beats Audio, I won't turn it off)
I tried also some of the custom roms here on the forum but nothing changed... The biggest "ram-eating" applications i have always on are whatsapp and Fb messenger, i wouldn't think it's because of them.
I tried a lot of combinations, this one looks like the better one (music stutters only sometimes).
This problem doesn't exist only with stock music player - that means there must be a way to solve this - but i don't use it because it lacks of a lot of things.
Has anybody ever experienced this problem? Any help?
If you are rooted, you can give another kernel a try.
Maybe stock, oc kernel like Stockbeats Kernel.
Don't forget the backup before.

Flashbeats rom use Flashbeats kernel, Stockbeats kernel is a bit different to that. So maybe try and see if it helps.
I installed it buy still stuttering when i open browser while listening to music or turn on wifi
Maybe try to change oc, govenor and/or I/O scheduler.
If this also don't help, i have no idea atm.

I have the same stuttering problem with stock JB rom and Poweramp and Google Play Music.
I haven't managed to find out cause or solution. Basically any third party music player is practically unusable.
Stock music player works perfectly, also to my ear with superior music quality, but not having gapless playback in 2013 is unacceptable. It's probably the only serious defect of the phone.

Exactly the same... and I am still hoping someone will find a solution i am no expert, but maybe the fact that with stock music player everything's fine means something...

I am using trickster mod to see if something changes, can you help me with the settings? I don't know what they mean, and where it would be affecting the music stutter..
Right now its settings are:
TCP congestion : cubic
Read Ahead Buffer size: 128
Scheduler: cfq
Block frequency: YES min 384000 max 1566000
Governor: ondemand (changed into performance a couple of times)
MP Decision OFF
Multicore energy saver:1
GPU -Governor: Ondemand
Max frequency 400

Sorry, i don't use Trickster mod. There must somebody else that tell you whats going on.
Hi.
FYI on stock kernel and rom, I tried winamp and there definitely was some stuttering.
On spotify or stock music player no problem at all though.
This behavior doesn't change after the update to Android 4.2. Play Music and Beyondpod still have the stuttering, only the stock music app works fine.
It is also becoming a more significant problem because not only the stock app does not support gapless reproduction, but also when I switched to the Google Now launcher (which I like better than Sense 5) I can no longer use the music widget.

I solved with playerpro & DSP pack, setting audio buffer to maximum and audio priority to maximum + it supports gapless. I have tried millions of possibilities (kernels, deleting stock apps etc.) but this is the only one which seems to be working in my case. Poweramp stutters less than google play music but stutters anyway (even with high audio priority etc)
You can't get the music widget of the stock music player because it's only a sense widget works only on the sense launcher, unfortunately
Hey guys. Can somebody please explain me shortly how the CPU governors are and what are their features?
I use my phone for daily-use purposes like browsing the internet, playing games, and listening to music. Now what is the best choice for me to use? and by the way I'm using the mosh kernel.
Many thanks in advance...
Hello! Maybe u want see this theard: http://forum.xda-developers.com/showthread.php?t=1736168
I have a FiiO M11 Plus digital audio player (Snapdragon 660) that I also want to use as a game device.
After a factory reset, I downloaded a game to play test. It ran smoothly, with some understandable slowdown as the device started thermal throttling.
I then force quit the game to see if it would continue running smoothly and it didn’t. The audio was immediately choppy upon running the game when it wasn’t before. From previous times I’ve tried this, the choppy audio meant the game was unplayable.
I’ve noticed that after a reset, some keyboard apps show up and quickly disappear. Is there perhaps an initialization script that sets a performance limiter? I’d assume it was set so the device can maximize battery life for audio playback but I don’t want that while playing games obviously.
I’ve been able to root this with Magisk and I’ve tried
stop thermal-engine
as well as all sorts of things in Stratosphere.
Is there anything I’m missing.
Gaming device ? what gaming device ? for candy crush i presume. that music player was not built for gaming. it will heat up quickly. you want to disable thermal-engine ? for something made not to be a gaming device, that might mean certain hard brick. and an expensive hard brick to fix. i strongly recommend just buying a phone for those gaming purposes.
I probably will use it for playing music 99% of the time, but I don’t like my device arbitrarily lowering performance in a way I can’t see.
Furthermore, I don’t understand why it can start off playing a game well and then lose performance on relaunch.
I enjoy the music and I’d also like to enjoy the android aspect of the device as well.

A large part of using any electronic device is whether or not the device is suitable for the purposes you intend to use it for. When choosing between a rock and a hammer to drive a nail, why would you choose the rock when the hammer is much more suited to the task?
