[Q] How to fine tune my phone ?

Hey guys, sorry if this is a question for beginners but I've been looking through XDA and I cannot find a proper page on how to fine tune your kernel to get all that you can out of your phone. Currently I am using the 11/9 version of HellyBean and I was hoping one of you guys could post the settings that I should make to make my phone run as good as it can. By settings I mean: what RAM settings should I use (XL,Bigmem, ZRAM...), at what frequency should the proc be running when the screen is off/on, and so on. And please if you can also post an explanation as to why you use a particulat setting because I would really like to broaden my horizon when it comes to android information/tips. Thank you guys in advance for your time and information, have a good one...

i use system cleanup from the market for removing apps and stuff i don't want. i use big memory 402 in devil config. i was reading not to zswap. hope that helps a bit.

Live OC problems

Hi I have Fishear's ROM 13/01 and I really like it....
only one thing : I have problem setting live oc...this happens in evry ROM so that's why I didn't post it in his official thread...
In games it's stable up to live OC 110%....past it the game crashes or it reboots...can anyone help me with the settings??
Do I have to change voltages???

It's normal to get instability past 110%, some even have to go lower.
You might get better results with overvolting, but it's risky and might not be worth it.

[Problem] Cannot hear People while calling

Hello at all, I got a problem while calling. When i call somebody or i am beeing called, i cannot hear anything, so i have to switch to the back speaker... Is this Rom related or Do I have to give my Phone back?

Try to reflash the rom and if this doesn't fix the problem it should be a hardware prob

i had similar issue, but mine was that microphone stopped working while talking to people in the middle of conversation. switching to speaker and then back to normal was temporary fix. turns out it was Viber acting something up, when i deleted Viber i haven't had problems anymore

I dont know what viber is, but if it is an app, i dont have it installed

yeah, it's an app. sorry i couldnt be of more help

I also have the same problem before. Other party of the call can't receive my voice suddenly. It will happen so many times during a long call, I need to switch between the speaker phone and back to the normal speaker every time when it happen.
I started to have this problem after I flashed to Leak version of 20A. Then I flash again to official version after it released. No help either. I did also posted a question in here. No one can help too. I then ignores it for a while to see if there is anyone can help. But this error happens too much. I found it is too annoying.
Then I change to CM10.1 and wipe off all the system cache and data etc. Now I got everything works again. I did installed Viber. Maybe you can also try factory reset to see if it helps first. If it still won't work try to change to CM like what I do.

I get a really quiet call volume for no reason, it rarely happens but its annoying because I work for an agency that calls me to book shifts. I think our cheap hardware is just crap

Hi,
sometimes it works normal, i dont understand it.. I've already factory reseted a few times, so i think this might Not be the problem... Thank you all, maybe this is just our Phone...

Hi guys, same problem for me. I've done many upgrades/downgrades/restart...and the problem persist. Hardware problem??
But in one of those flashing (v20b) the problem disappeared.
I haven't got any guarantee because I bougth the phone in ebay.
Can somebody help?

Could this be the solution?
OK guys: This may or may not help you:
I found that, when I place a call, I do not hear the ringtone, and the first few words of the person that answers.
Momentarily switching the speaker "on" (push "Speaker") , then "off" (push "Speaker" again), seems to solve the problem.
After a lot of testing, and eliminating certain possibilities, I found that this problem in my case is associated with the phone being connected to another device via Bluetooth (in my case my X-Link unit).
When I disable the Bluetooth feature, everything works great.
Perhaps, this is good to know . . . . .

Nope...
Unfortunaly not the solution...
Thank God i dont need to call People often..
Thx for this anyway, maybe it helped others

Still with it
Hi guys, me again. The problem persist, a technical service told me the cost of reparation is about $50. I don't know if its a fear cost. Whta's your opinion?

HI ,
Could you please guide how to Flash the ROM for LG Optimus 4X HD P880
Thanks

laggy jellybean 4.1.2

hi,i've always been a fan of the optimus 4x hd and finally bought one a week ago. was too excited to update to jellybean that i ignored all the problems i heard about and now i can't live with the problems in this update.
i read about a lot of problems with the update but after using it for a week(heavy user) ,the only problems i see are the lag and the slow charging.
i could've lived with anything but this lag is too much to take in. it gets so painfully slow sometimes. i mean,it's a quad core beast for crying out loud!
what is the best way to fix this?
should i go back to ICS?
should i root and install a custom rom??
any help anyone can give me will be greatly appreciated.

Install custom kernel and wipe all. There should be no laggs. Or flash custom rom and kernel or roll back to ics.
There is already an jelly bean lagg thread. Why not use search function ?

what i mean is what is the easiest,safest way to fix it. the phone is brand new (and quite expensive here) i don't wanna brick it or something.
does any of these solutions require rooting?

Yes, they require rooting, unlocking the bootloader etc. Please, please start using the search function.
If your phone is expensive and you can't afford to risk it then you shouldn't ever be messing around with it as there is always a risk in anything.

To reduce the lags,
Type 3845#*880# on the dial pad and enter the hidden menu.
Scroll down, select MLT, uncheck the box at the bottom and restart your phone.
For fast charging, enter the hidden menu, select Module test/Charging test. Check the box at the top, replug your charger and voila!

No you don't have to do that. MLT has nothing useful for the end user.
Backup your data and try factory reset for the lagging problem.
Sorry but these are the only two solutions i know.
If you decide to root your phone one day, you may try LGP880 Booster for better gaming experience and fast charging. Search the forum for the download link.

It's not about being stupid. The very first rule of XDA is to always search before asking any question.
I wasn't being rude or condescending, just honest about the risk to your phone if you can't afford to take that chance.
Maybe you should consider winding your neck in a little bit, you're new on here and need to learn the rules before you go mouthing off at people who have been here a while and take a lot of time to help people on the forums.

thanks,again. i appreciate you taking the time to reply

Try them out and judge for yourself. "Best ROM", "Best Kernel" etc threads are not allowed on XDA as you will get as many different opinions as people who reply, and they tend to lead to arguments.

[Q] N7000 wifi issue (temp solution provided)

04/10/2013
For these who suffer similar problem like me, u can try this fix see it work on you or not. It is not a perfect fix c/w some random freeze bug but at least it settle my WIFI issue for temporary.
Is was a wifi file from 4.1.1 JB LS2 rom. i extract it from Rocket ROm LS2
U can flash it in recovery but before turn it to recovery make sure u off ur phone wifi 1st and if u can't off it u can used airplane mode to force it off.
View attachment sample.zip
Happy trying and do give feedback how was it so it can help more ppl out there.
Some other user experience after post #26 had a check too
hi i just upgrade my N7000 rom from LSZ to LT4
After i upgrade i notice one weird thing that my wifi become unstable which it will shut itself down after sometimes and than it hard to turn it on.
It just stuck and searching network or turning on..... than off against
I wish to know it is anyway to check the bug?
I been trying different kernel from Phizl-hydra-sppedmod all also give bad news only.
Is that any different wifi module between LSZ era and newer rom?
Not only few of user from my country forum also suffer similar problem that had hard time to turn the wifi on.
i kind of worry there is process or error that auto kill the wifi off
Hope pro here can guide me to solve this mystery and i been searching on google which seem no had any final solution to this.

You are not alone in this. I'm searching Google almost everyday as I have the exact same problem for more than a month now. It started few days post flashing ultimate ROM coming from the good old Criskelo ROM.
I've tried almost every software (ROM, KERNEL, STOCK and CM) and hardware solution. Still can't figure out why it happens!
But what I'm quite certain is it isn't the WiFi chip (bluetooth still works) nor hardware (changed batteries and the charging port board).
What I can advise is to try another modem I found that XXLPT works best for me. Wifi is more stable, reconnects immediately on disconnections, and less Freezing. However, I till have infrequent auto reboots. Reboots are relatively better than having a phone that doesn't wakeup from lock or screen of deaths that drove me crazy.
You will find others are having problems with LT4, I did too.

Yes I did change my micro USB port with an original one from another screen broken phone. But the WiFi is still acting strange. Seems unrelated to the problem. Opening the phone and cleaning inside and reconnecting cables didn't work for me.

Did you make sure the revision number matched? If not and you still have the original part, have a look and check if it's the same. If not it won't work properly even though it's from another note.

Did reinstalling the ROM solve your Wifi problem? I've flashed and reflashed so many ROMS now that my phone is starting to glow.
Referring to your question, yes, I have tried other SIM cards.
