Now that it is summer it will get a bit hotter, but don't worry. First do not leave your phone directly on the sun, check even in your pocket, it tends to get hotter there.
As of software-wise, if I remember correctly, the stock 5.0 lollipop firmware was the best in terms of heat. Also see if you can UNDERclock the Cpu, yes it will work slower but will operate at lower temperatures. Also check running apps, I can recommend uninstalling Facebook app and the Messenger also.

My phone its pretty slow with jb 4.1 with fat drain battery

Hello people of the forum I'm a follower of all the threads about this amazing phone lg, but lately I start to see some of this problems:
- the common lag of the main screen that takes about 10 to 15 seconds to load all the app launchers
- the battery is the main problem when I fully charged I could easily loose about 15 to 20% of the battery with 20min of usage during a video or light games
- when I load videos of YouTube they get pause itself and it restart all the video again
- some games like jewel dash (that's is a light game) kick me off after a few minutes of play
- I changed to jb from its mainly because the heat of the phone during playing videos or games, although this problem persist after the update
I applied all the things what the forum show like the factory reset after the update the wipe data. I installed the firmware with kdz tool... I will appreciate all your help about this subject I'm really de desperate... Btw my phone is rooted but I'm very newbie on this subject of cyanogedmod and the flashing so be comprehensive on that
Thx for all ur help
First go to settings and factory reset the device and then boot in stock recovery and choose wipe data factory reset and wipe nv partition when finished remove the battery and reinsert it and flash the firmware with kdz update when flashing finished root your device and then install supersu integrate(move) into system and factory reset again and then use a root file manager go to root>system>app and delete lgmits.apk and mlt.apk and reboot
I used this my own method my 4x is butterly smooth and also better battery life.
To improve performance use greenify,in developer setting select background process limit atmost 2 process it's resets in every boot,and also select animation effects off

Do you think tegra overclock will improve my phone and how I can use it? Thx for ur help

You can control the active core like lg gear box but don't use cpu clock or changing frequency governor, you can also force all selected core online to improve games performance and also you're able to overclock gpu

How can I use this app for improve the battery life and produce less heat? I'm using one core right now as I read on another thread but when I want to modify the gpu clock it don't make the chance it's permanent on 50 Mhz as I read on another thread it's because the cpu and gpu r not unlinked how can I modify in this case mu gpu? Thx for ur help

The default value of gpu is 200 and i chaned it to 330

And how I can reduce the drain battery and the heat? That's my main problem

Try to uninstall Google Maps and Google Plus also use greenify to hibernate user apps.
Heat is normal for Tegra3 processor

Ok and the gpu c. Clock on 330 and how many core I should use during normal use of phone and how many for game performance

An this one's r the setting of tegra overclock
Enviado desde mi LG-P880 usando Tapatalk 2
Don't use core selection because tegra3 uses cores selection automatically, it's enables and disabales cores as requirements but lg modified it to prevent forcing all cores online in games.
So gaming you can select 4 cores online and normal use just select 2 cores

I don't experimented yet with tegra fps you can search in google for more info.
But normally in every 4x cell standby is in top on battery use.
For gpu clock select 3d at 380mhz and 2d half of the 3d value.

If the phone is hot when charging then you will get the slow charge. You can overcome this by going into the hidden settings and enabling the unlimited temp charging under charge test. Bu you will have to do it each boot within hidden menu. or you could install Iodak kernel and enable the fast charge. Set max 1200 min 102 cpu in trickster mod and remove tegra overclock because that seems to cause fast batt drain and overheating. (don' ask my why but many people have reported tegra overclock causing this)
Hey thx for the quick answer I did remove the tegra overclock I do the hide menu thing about module test charging unlimited but the problem persist always I never tried with customs kernels and idk how to do it in any case I really need a help on this

If you have Clockwork mod installed and a unlocked boot loader its just a case of installing the Iodak kernel. pretty easy just look through the general section on how to do it.

Also if you tried the hidden menu unlimited temp charge make sure you have your usb cable unplugged or it will not work. Plug it in after you select the setting. But remember it does not stick so you need to do it each fresh bootup.
Well I did the trickster mod of the min and max but I really need to get done with this problem and I don't really know what to do

Iodak kernael is the best for your problem, Just try reading the forum under original android development for 4x iodak kernel. It tells you how to install and its not that hard.

[Q] Xperia T turn off alone

Hi to everyone,
I have a little problem...
When I put my phone charging, sometimes it turns off alone. Isn't all time.
When I wake up and I'll take it, sometimes it is off...
The problem started when I upgraded to 9.2.A.0.295.
Anyone else is having this problem?

It's a well known bug. I use safe charge app from playstore and I don't face that problem again.

How do i do that? Preferably without a computer
Settings/application manager/all apps.
On that list tap on app name and select disabled. That's all.

Its more than just disabling any app. We need to know exactly what is causing the lag. If it is an app, then which app? We cant just be disabling any app and hope one stops the lag. There is another post which discusses the same lag issue but there is still not one single solution to it. After several updates on the phone, it still has not solved the lag issue. I am using a N920CD, I get the lag everyday for couple of seconds.
Does anyone know of a proper permanent fix? What is actually causing the lag ?

Actually, I had lag on mines when I updated to the latest firmware apa2. I went back to aok7 and its running perfect again.
Ok, I have to retract, lag still here. It's not lag it's a random freeze when unlock screen
Enviado desde mi SM-N920G mediante Tapatalk
Yeah, such an expensive device and it has been lagging/freezing since I bought it. The updates have not fixed the issue. We need a fix. If anyone out here know of a fix, do let us know. Sometimes I feel like smashing the phone on the ground, especially when I need to act quickly to make a call or answer a call and it freezes, p***** me off differently.

Light speaker distortion

Hi all,
I have the P9 since a few days. I've noticed a quite light distortion (a little 'crank') but only with a particular sound, that one that sounds when you click on the microphone button to enable voice recognition, for example on google now or play store. When I press that microphone button, sometimes it starts with a very very short and light 'crank' (I don't know how to call it). It doesn't happen always, only sometimes.
Has anyone noticed?
Regards
Can anybody try please?
Thanks!

Something similar to this?
I'm pretty sure that's because the speakers and/or amplifier only turn on when used, thus sometimes making that "crackling" noise as if you plugged in headphones
Yes, that's the sound. I understand what you say, but I've only experienced it with this phone

I don't think we can do much about it, either. Seems like a hardware thing. Doesn't really bother me much though, but I understand if it's annoying to you.
Thanks for the response. I only would like to know if it is a particular problem with my phone or a general one.
