[Q] LG 4X HD serious lag problems - LG Optimus 4X HD

My LG 4X HD was running 4.1.2 JB and using Optimus UI. Using it daily, I experienced lags in occasions such as: entering app drawer, presing the home button while running some apps, unlocking the phone etc. So I turned off animations, device was suffering lag less often, but still it annoyed me. I decidet to install CM 10.1 hoping that lags will dissapear, but nothing changed dramitacally. Phone runs smoother now, but it's still laggy(Animations turned off even now). I have installed cca. 10 apps on the device, and it shouldn't be a big problem for device with quad core and 1GB of RAM. Any ideas what could it be?

I had same problem with lag all around on 4.1. I had best experience in v10f, that is android 4.0.

my suggestion would be flashing original KDZ first and after doing so wipe it clean before attempting to flash custom roms. 4X has 4 cores and 1 GB ram should be able to handle multitasking well. Help this helps.

it's embarassing how lg doesn't support this phone that with the jb update is full of lags. I've installed cyanogenmod with yodak kernel. Now my mobile phone is a Ferrari

I for myself think that stock ROM (V20B) + iodak kernel v06 is the best combination possible for a good balance of performance and battery life.

Very slow Galaxy S

I have galaxy s since last one year and i love it... However my phone has become very slow these days.. I tried several roms and kernels.. Formatted both internal and external SD cards... But still it is very slow... I remember that I dropped it 3-4 times... Is it because of it?
Can someone suggest me please... What should I do...

Maybe over clock it ...? I thought the new ROMs would have helped. It could be the fact that your phone is older now and some internal hardware has been worn out

Can I do anything related to the hardware? I mean how can i check if it is not giving 100%?

I'm no expert so I'm not sure. Best bet would be to replace the hardware which Costs a ton of money. Its better to just a get a new phone. Either that or maybe mess around with new ROMs some more. Maybe you are wiping your phone incorrectly or maybe you use it too much

my suggest...
1. update your firmware to last version (2.3.6).
2. try to change kernel and custom rom.
3. maybe, with some different kernel and custom rom, you can choice the better option for your device. for example, try using kernel semaphore (gingerbread) and custom rom F1 or other.
I would be very surprised if physical trauma has simply caused a slow-down in speed. It would more likely show itself as random reboots and other more obvious symptoms.
Much like Windows, after a lot of use, it slows down - you have said that you've flashed other roms, maybe you just haven't come across a good one; there are after all a lot of different ones...
I would suggest the deodex-ed / rooted stock rom from RAMAD Gingerbread JVT. As I remember it was always quite stable and fast.
The hardware components inside a modern phone will not wear-out after a year - they are not moving parts! - when ram or a processor wears out it usually results in total system crashing not just a slow down.
Thank you all for your feedbacks and suggestions. I use my phone a lot. Usually i use TV out a lot as i do not have a cable connection in my hostel room. I use my phone a lot. I flashed it atleast more than 100 times. I have not seen any reboots, crashed , soft reboots etc very often. When i use MIUI rom my phone is very fast indeed however , it does not have a TV Out and therefore i have to use a stock based rom.. i will try Rammad's GB Rom as per your suggestion and will report back. As i told you that i dropped it a couple of times, is it possible that any of the Internal components have become loose?
Have you ever tried Advanced task killer? Or even killed tasks?

Did you try the ics roms. These r pretty fast..specially team icssgs.

Try ICSSGS RC 4.2. I had the same situation as you. It was fine for one year and I was using Darky rom by that time. Suddenly I started feeling that my phone is too slow. Lot of stuck. Sometimes I had to remove battery just to restart.
Now running above ICS rom with Devil 14.2 Kernel its rocking ...
yeah I'd suggest u the advanced taskkiller too
in options you can set the auto killlevel to safe, so that it kills smth like games in the background but not important apps
since then my phone is quite fast even with stockrom

Yeah, and you can just use the ATK widget when you close out of something press the icon and it kills all the background apps...
I will surely try ATK and ICS roms as per your suggestions...

keep us updated...
Just get stock jw1, flash with reparation to wipe everything, then do a factory reset via secret dial code. Now install semaphore 2.5.0 kernel. Dl superuser to get root. Now install thunderbolt tweaks the main package and the 60lmk other addon(read thread how to) . This is the best setup i can think of in terms of speed bat life and functionality. Next step look in pikachus Android optimization thread and remove the bloatware listed there, basically remove as much bloat as possible. Enjoy ur fast phone.

Perhaps you should try the ICSSGS RC4.2 with Devil 14.2 LED VC Kernel. I'm on it and its awesome, my phone lags no more and I'm using it for my primary phone.

high ram or something else is hindering my phone performance

I am using note(n7000) and on stock xxlt9 firmware. This is the smoothest firmware released from samsung till date(un branded). I have removed many of the bloats by samungs and hong into root i have cleared 100 mb of space...( believe me,apks are placed at many places). Still my phone lags. My ram usage is above 80% always...i hardly get 150mb off free ram. I use greenify toh hibernate maximum apps. I don't know whats happening...and pls dont say that free ram=wasted ram...that means u havnt used android properly. I tried my custom roms based on touch wiz and others, bit none of then suited me. Yesterday i flashed cyanogenmod 10.1.3 and its working like charm...ram usage is almost the same...or i may b getting 20% extra...but phone is buttry smooth . But i am having one confusion. Suppose i open xda website in default browser
Then i open some other website in chrome,then whatsapp then fileexplorer. But now when i go to default browser that xda website is still open...wow to my surprise. That never happend in my android experience. While on the other hand, on touch wiz xda website will reload . Why is it so?
When my ram usage is hig and i play game it lags....although game itself clear outs ram but still it lags...i had to revert back to touch wiz from CM because i am too addicted to features line multi window, s pen gestures, pop up play and others. But is it possible to have that performance of cm in touch wiz?

Download this one, try to flash it with mobile odin, if you dont know that program.Find it, download it and intall it to your device,run it .Then:
1->locate the open file option (be sure you unzip the file you downloaded (the rom) because if not mobile odin wont recognise it.
2->A popup saying a couple of files were loaded will prompt, just type ok
3->Scroll down a bit and make sure the 3 or 2 root options (dont remember correctly) are ticked ,so that the flashed rom will be already rooted.
4->Finally start flashing,(remember to have more thank 50% battery when doing so, just in case so nothing can go wrong.
After flashing the rom you will need to flash the helloworld kernel, and if you flashed speedmod im sure you know how to do it, if not shout me and i will show you .

I told you what you can do in first. You can use newest CoCore kernel, put PegasusQ as governor, SIO as scheduler (with No Frill CPU app from Play Store) and debloat it (remove Samsung crapware). And that is it. Or go back to GB. Next solution is better phone sadly...
P.S. You have option in developers option to put max apps in background - do not put it to 3, put to standard limit.
Settings> Developers options> Limit background proccess.

Stock 4.1 vs Stock 4.3

im on .207 and im thinking go back to 4.1 .254
which is better?
i have a long time on 4.3 since .201 and i dont remember 4.1 perfomanence.
thanks
Do it!
I've used every stock 4.3 rom. Was very excited when it launched.207 is the best 4.3 rom,but for me after a while it starts to get slow,launcher redraws and everything and i decide to go back to .254. It was a GREAT decision,performance and ram management is far better than on 4.3,phone is much more snappier,and i like the interface design better than on 4.3.The only thing to me that's better on 4.3 it's x loud. Its louder than on 4.1 but not by a much.
I have 4.3 207 and its ultra slow when i open wifi, fb and messenger are ultra slow , and lags and phone hangs alot , rrally neef help, the phone is ltle smooth offline

Do a nandroid backup, try slimkat and see
If last slimkat avoid access to sdcard, try slimkat 8.8.
If there is any problem, you can restore your nandroid backup...
So for no problem, you can save nandroid backup on pc
Stock 4.3
From my experience I can say the following...
In regards to 4.1.2 (stock):
+ Virtually bug free.
+ Smooth performance (good free RAM).
+ Exceptional battery life.
- Poor Wi-Fi range (only bug I found).
- Okay camera.
In regards to 4.3 (stock):
+ Great camera.
+ Smooth performance.
+ Receives media app updates (not sure about 4.1.2).
- Poor RAM managment.
- Uninstalling app graphic glitch/lag (can be fixed with replacement packageinstaller.apk)
So I personally would stick to 4.3 (I fixed the package installer) and am a light user so RAM doesn't bug me too much, the Wi-Fi issue on 4.1.2 was the only issue but killed it for me, otherwise 4.1.2 would've been perfect.

Yeah, that ROM is very popular and for a good reason-yet to try it though, I will wait till I am bored to death with stock ROM. Relating to the op, I don't like the feeling of being on an older android version when a newer version is available, hence another reason I'm on 4.3.
I also see you'll be selling your SP (sig), may I ask why?
After countless flashes I've decided there is no better firmware/rom available than the Stock 4.1.2 (.254) for this phone.
I don't care which android version it runs as long as it runs smooth and fast.

[Q] Super Laggy Xperia SP

Hello everyone,
I bought a used Xperia SP but it is very laggy.I tried both stock 4.1 and 4.3 but it's very slow for a phone with these specs.My Xperia T with worse CPU and of course much worse GPU runs butter smooth but the Xperia SP is slow.It's hardware or software issue??

You have many installed apps? And it has little memory or memory ram? If this is the problem, will have to root q, and if you have a class 10 card, move apps to the card, if it is a basic, just move the light apps that do not require a large perfomace I in here my xperia sp android 4.3, I have no problems of slowness.
I have helped and I deculpe by bad english
Cr*p Software
As you mentioned it is slow for it's specs, the hardware is still strong by today's standards and can easily run Jelly Bean, the problem is the software and what Sony have done with it. I also have slow performance on JB 4.3, I have removed much bloatware and installed greenify but still have poor performance (can barely multitask, opening 2 tabs in chrome will close Walkman whilst playing music ). The reason is mainly the kernel, the min-free (RAM) values are poorly tweaked hence we have low RAM and performance. Compared to 4.1.2 JB, 4.3 JB is a lot more resource heavier due to the added high end graphics support.
Hi there,
As you've mentioned above, I think there may be some software installed that are slowing down your phone. If you use the stock rom, you can try backing-up your SMS, contacts and apps(always remember to backup), then factory reset the phone('wipe') in settings-backup and restore.
Also you can unlock and root the phone for a better performance, but be cautious, for unlocking void warranties.
I don't have apps installed...but ok,Sony's stock ROM is ****...why CyanogenMod ROMs have many problems too??
You can try flash a ftf file with flashtool. It totally rewrite the system on your phone.
Unlock bl and try cm11.
1. Flash stock .207 with flash tool
2. Root it
3. install custom recovery cwm and then try some custom roms for locked bootloaders from android developement section
http://forum.xda-developers.com/xperia-sp/development
4.3 custom roms highly recommended for battery life

Yeah Sony's stock ROM for our phone is bad. CM11 (locked bootloader) is a million times better, no crazy battery drain, 400mb+ free RAM (will all my apps), very smooth. Its easy to install as well (no need to unlock your bootloader). Check this out.
Follow matsas's instructions as above but instead install CM11.
