Rooted my Tab, Now what!

Hello all, i rooted my tab today. Installed Superuser, Set CPU and Titanium backup. I froze a few of the pre loaded Samsung apps that came with the Tab. What other things can i do to speed up performance now that i am rooted? Any suggestions?? Thanks!
(Also if anyone else is currently using Set CPU on their Tab7 +, what settings work well for you? )

Which model? (There are at least 4 different ones.) Are you willing to give up battery life for that speed? What do you want to use your tablet for?

I have the Wi-Fi_GT-P6210. I guess my main issue with Set CPU is what are the limits i can go to without locking up the device. I have Set Cpu on my EVO 4g so i am familiar with it. I guess i was just seeing what advantages rooting gives me. I have my EVO rooted so i know the benefits on my phone, but what about the TAB. What apps can i remove without effecting performance. Thanks

If you want to overclock or undervolt, you'll need a custom kernel (see my sig.) At that point, you can OC to 1.4GHz. (I didn't include support for 1.6GHz has the processor in my own 7+ wouldn't stay stable at that speed, so I can't test it properly - it was also extremely easy for me to only add 1.4.) For voltages, you are also kind of going to have to experiment. I'm stable with 1300/1225/1125/1025/950/900 on my tab plus, but I can go much lower on my SGSII (which has the same processor.) You can search on the SGH-i9100 and SGH-i777 subforums for what other people have done with voltages.
As for which apps can be safely frozen, there's a post or two on that from a couple months back... I'd suggest searching for the full list. Nearly anything that looks like bloat really is.
I'd never suggest actually removing stuff - much better to just freeze it... then if you figure out that you really needed it, it's trivial to defrost it.
Good luck

Disable scrolling cache & more!

I will slowly be adding more tweaks as I come across them so check back once in awhile.
Standard disclaimer: Use at your own risk!
Basically disabling the scrolling cache will reduce lagy and chunky scrolling. You won't notice a huge difference unless your scrolling through something your phone usually has a hard time with. Anyone that has Rom Toolbox would understand chunky scrolling on the first page of the app. So if you have the app, test it there. In general, icons will appear instantaneous and everything will run a bit smoother.
So here is what to do...
Use your favorite build.prop editor and add a new line.
persist.sys.scrollingcache
Set it's value to 3.
Reboot.
If you really want to make things extremely more responsive then adjust your vm.stat_interval. I do believe the default is 10. If someone could verify it before you change it let me know. Setting the value lower will increase the responsiveness of your phone a very good amount! Start at 8 and slowly work down. There is a chance you will become unstable so use caution. I can say I have set it to 1 (lowest setting) without a single issue.
Do not expect to increase your benchmark with this because it will actually drop a little. This is a perfect example of the whole benchmark debate. Your phone will be flying but quadrant won't show it.
Use the "SCOL" app to adjust vm.stat_interval and save your value. There is no need to reboot and the results of your changes are instantly applied.
Yes. It is most likely going to effect battery life.

Hi everybody,
I have 2 questions:
1.Doesn't one have to do something in framework.jar to disable scrolling cache?
2. What do you mean by "set it's value to 4"?

Wow I thought this got buried deep in the archives to never be seen again! Anyways, at the time I wrote this it is my understanding that basically...
1=cache on always
2=cache on certain times
3=cache off certain times
4=cache off always
Not like I haven't been wrong in the past though.

So if I want scrolling cache off, it looks like this, or?:
persist.sys.scrollingcache=4
Thanks for your fast reply

Yup thats it

CM10.2, Neak Kernel => Tried, saw no improvement.

Wow,thank you, this tip made my scrolling smoother, and it was so simple.

sorry for coming to such an old post,
but isn't scrolling cache meant to improve scrolling performance as it builds what it has to show next in the cache?
i just wanna understand the technical side of things.
mainly because if enabling it reduces performance, why do manufacturers enable it?
cheers

I had the same thought. If setting it to 3 is so much better, then why would anyone (companies included) want to set it to something else?

High Load in cm10 and Roms based on it?

Hello,
I have noticed, that the load* (not the CPU%) under several CM10 (or higher) based roms is very high, i.e. >2.
This is true for PACMAN, JellyBam and the CM10 nightly.
Can someone please have a check by activating the CPU-Stat-Overlay and post the line that looks like 2.7/3.0/2.0?
Is this a known problem? I once had a nightly of CM10 on the Phone, which ran very well. I do not think, that it had this problem...
I do not have this Problem with OptimusRS which is based on the Official ICS. Here, the load is lower by a factor of 10.
*in contrast to the CPU usage (%), the load also captures if the system is blocked by something other than the CPU (I/O, ...)
Greetings,
Hendrik

Well, that's quite high, still.
Was that after the device was ideling??
When I have not used the phone for 15 min, I get 0.02/0.02/0.02.
Your values show that your phone is really busy (values > 1 means that it is over-loaded).
Are you happy with the responsivenes of the phone?

The first value is now, the second 5 minutes ago, the last 15 minutes ago.
So, your device/your Rom seems to have the same problem I experienced.

I come back to CM-Based rom today...and i noticed that in Jellybam and also Bernie's rom the CPU usage is really high...the cpu stays every time at the higher frequence and the back of the phone is really hot! I noticed this problem also with MIUI rom that are also CM Based, i need to change kernel for trying correctly Bernie rom! With Pesach kernel for CM10.1 the thing seems good..but the phone stucks ever at the minimum frequence...and it never go on deep sleep!
Is really strange! I tried bernie's also when it came out some time ago but it hadn't this problem! I think that is a recent problem!

Install wakelock to see who do that. put wifi to sleep when screen is off. Uninstall the programs that you do not need.

Well, I suspect the obstacle might be the CPU driver - I don't know if LG have ever used Texas Instruments' default values or just made them up by themselves although I suspect it would be the latter since I have used Tegra 2 based phone before (hacked, of course), and it's surprisingly smooth so there may be explanation somewhere in either second-stage BIOS or in the kernel for the 3D phone and no I am not pointing the finger at any developers here as there are variables that have to be checked down.

I don't understand, what you are saying...
For me, it is not yet clear, whether this problem exists on every phone, and whether it is on every rom.
When I started using CM10, I did not have this impression. Does someone have an old version on CM10 and could check?
What about the others? What are your LOADs?
There must be more users...
Greetings,
Hendrik

CM10 only load the values which are in the kernel which you can install separately, and some kernels have better CPU values. Not to mention there is 410 MB assigned to CPU.
However in some case, BIOS is what make or break this phone (BIOS boots up first and displays red or silver LG logo depending on whether BIOS is unlocked or not, and is responsible for loading Linux kernel, thus booting Android OS up). So it's hard to say but I might want to try assemble the BIOS on my own and see if problem persists in some OS images (FYI, BIOS development is much harder than Android OS development).

Hello,
I think, it is worth to go back to an older CM10 Version, because I am quite sure, that it was better there.
What really surprises me is, that I am the first and more or less only one to complain. For me, PACMAN and JellyBam were unusable, CM10 was also quite bad.

You're not the only one...some days ago i went back to CM-Based roms and i noticed that they never go in deep sleep! And the phone goes hot...the only rom where i hadn't this problems is the Baked Blackbean by kidkoala...also MIUI roms have this problem!

Hello,
is there anything new on this topic?
Can anyone using CM10 or higher confirm, that he does NOT have this problem?
(to check:
Settings-->Developer Settings (very bottom) --> Display CPU Usage (far down)
let the phone rest some Minutes.
An Overlay is shown. The first three lines are of interest
--> Are the values low, around 0.1? --> no Problem, all good.
--> Are the values high, around 1 or higher --> you have the Problem.

Possible to change screen resolution?

As many of you are most likely aware, the Quarks have a 1440p display. This resolution is higher than the standard 1080p a few years ago.
This creates lots of battery drain and CPU and GPU strain as the device must drive all of those pixels. Our devices can do it with relative ease, however I seek a way to downgrade the resolution to 1080p. This would help battery life as well as performance.
It's possible on an LG G3, so I was wondering if it is on Quark.
Any ideas?

Yes, I found this solution some time ago, when I was looking to save battery. But let me tell you that I haven't noticed any improvement. Anyway, you need a rooted device, install a terminal emulator app, and type:
su
wm size 720X1280

You will also need to change screen density, you can change it with this command:
wm density xxx
Click to expand...
Click to collapse
With "xxx" being the wanted screen density, I have tested with 300 and 280.
To restore original values, you have to type:

The only app I had scaling issues with is the moto display screen. No matter what DPI I set I could not get it to look correct (or unlock from it, had to hit power to get to the normal unlock screen) at 1920x1080. Also, the DPI editor in that app did nothing and you MUST change the DPI when going to a lower res. I always use the build.prop editor in ROM toolbox to change DPI. I had a good experience with it personally but I like the convenience of picking up my phone and swiping to unlock without having to hit the power button. Could've been placebo but the phone did seem a touch snappier and I broke 8hr SoT a few times when running a lower res. I assume that can be chalked up to using less power in any rendering tasks. I do probably average around 7hr SoT on stock res.
In short, if you like not having to hit the power button to unlock your phone, changing res isn't for you. If you don't mind I say it's worth a test run at the least as it is easy to undo.

Thanks for the information guys; gonna be trying this out over the next few days.

Question Awfully slow scrolling on POCO X4 PRO 5g

EDIT: I've done a factory reset and it stays the same. there is no intertia when scrolling. even at first step, when choosing the phone langage at first setup.
Hello everyone, hope you can help.
The scrolling is very slow compared to any other phone, I borrowed a samsung phone from a friend to show the difference. There is not inertia, it's really annoying, I have to scroll 10 times to see a long webpage. It is really a software issue, the screen is working perfectly.
The only place where the scrolling is smooth it's in the settings/developer options, see video.
Thanks all in advance.

I've never encountered this issue on stock ROM nor on MIUI EU ROM which I've flashed on this phone. See if switching between 120/60hz screen mode changes anything. Seeing as you have developer options enabled maybe you've selected so etjingnin there shouldn't have too - try disabling that. Have you tried factory resetting to see if that fixes it? Obviously backing up all your data first.

Although I think is not a matter of bad performance it's just the ROM itself Im afraid. It's a feature let's say.

PS: I've done a factory reset and it stays the same. there is no intertia when scrolling. even at first step, when choosing the phone langage at first setup.

If you've watched videos of this phone in use and you can see the scrolling works alot better than yours - if I were you, I'd return my device. If the issue was ROM wide then it could perhaps be a digitiser issue. If it's only some screens then I'd think it was a setting somewhere... Since you've factory reset your phone I'd say you can rule out a setting applied on accident. Haven't seen anyone else mention this issue yet

Hello, thanks for your answer.How does the benchmark look? Strangely the scrolling is super-smooth and has inertia with some apps or setting, for example in the developer settings and in the settings area in general is butter-smooth. My phone came with MIUI 12 and unfortunaly I've updated it straight away so can't really compare.
I've seen other people complaining:

Not so much lag but when want to move the cursor or scroll for editing it freezes. I am very tempted to buy another one as they're not cheaper and hope for the better. Same on gbord and swifkey using text and whatsapp.
