I'm running 4.1.2. from AOKP on a Captivate. Recently, while online using Maxthon browser, I intermittently get a distorted screen. Everything freezes and the phone reboots.
The screen distortion is like a double image with vertical stripes of broken lines. All functionality is lost and after about 10 seconds the phone restarts.
Is this a hardware issue, a kernel issue, a Maxthon issue or some other problem?
Thanks.
Joe

Are you overclocking at all? It's either that or your phone doesn't like the voltages provided by the kernel.

Kernel doesn't allow voltage changes. The CPU is set for 100 min, 1200 max. Are you thinking I should back down that top end? Maybe 1000 Mhz?
I'll do that and set the governor to conservative.

Hello....
Im on unamed rc-2
AntonX's kernel (newest)
I was listening to youtube i looked up for a second then looked down my screen was green with weird lines but the music was still playing i could see a blurry youtube app in the background did a battery pull running fine now....
Anyone have a issue like that??

Have you dropped the scaling down. And shut off the higher oc values? Typically that kind of thing is result of pushing the phone too high.

I agree with eollie, only time I've seen what you described is when I tried overclocking to 2ghz!

i used tegrak OC back when it didn't have the run for a minute and see whether stable option. And I had set on boot, OC to 1.65 just to see what happened. It turned on and then blurry freeze. Had to clear cache, and dalvik. Surprisingly, it worked.

** NOOB ALERT**So i have a verizon gs3, obviously, and i was wondering if there are any good overclockable kernels for the Galaxy Mod. I was also wondering where i could learn the basics of undervolting. So preferably a kernel which can OC and undervolt. Someone might have already answered this question but i dont want to look through 238 pages.
Here is the link of the Galaxy Mod thread----> http://forum.xda-developers.com/showthread.php?t=1953008
PM already includes overclockable kernels in his ROM, just choose the one you want to use when you install, I prefer lean kernel. All CPUs are different so the amount you can undervolt is going to vary but theres 3 general groupings for our CPUs, slow, normal, and fast. Fast ones will generally need less voltage and slow ones the most voltage. To find out which one you have you'll need to reboot your phone then open up a terminal and type in SU (enter) dmesg | grep ACPU (enter). Once you find out what kind of CPU you have imoseyon has a list of recommend voltages for each type listed in his thread over at rootzwiki. From there just try lowering voltage a little at a time.

Thank you for your help but I'm using the ktoones kernel how do I change it from there?
Sent from my SCH-I535 using xda app-developers app
Use his program called ktweaker.
Sent from my SCH-I535 using xda app-developers app
No I know that but how do I know when to stop under clocking does it say when I do the terminal thing listed above?
Sent from my SCH-I535 using xda app-developers app
The terminal command will give you an idea of how well it may under volt. I'm pretty sure KT already has it undervolted some so if you have a fast CPU you can probably go lower but if yours is slow it may not go much if any lower. Its basicly going to be trial and error just lower voltage a little at a time and see if it stays stable. If you go to low the phone will show stability problems, freezing, reboot etc. While you testing try not to have voltages set on boot until you have stable settings.

Thank you a lot Im going to try it.
Sent from my SCH-I535 using xda app-developers app
So tried it and the second line down said fast so I'm guessing I have a fast one. Now how much would I under volt it to on average? Sorry if my questions have obvious answers I just want to make sure i dont do anything to my first smart phone.
Sent from my SCH-I535 using xda app-developers app
Take it a step at a time, down 25mv across the board shouldn't be a problem to start. Just use the phone for awhile to make sure its stable before moving down further.
Sent from my SCH-I535 using xda app-developers app
So go down 25 mv then use the phone then go by 5 and use it? Thanks for all your help.
Sent from my SCH-I535 using xda app-developers app
That's the idea. Mine is a fast one also so I can give you my voltages but theres no guarantee they'll work for you.

Are there any apps out there that LEGITIMATELY help save/prolong battery life? I have memory booster running but that just helps my phone run smoother by killing cached app processes. Anything you guys can recommend?
Sent from my LG-P999 using xda premium
This phone requires it's own nuclear power plant lol.
Seriously though, don't use memory boosters. They kill battery.
My setup is, CPU Tuner with timeriffic to set display brightness. With Maz's latest kernel I can get by... mind you I live in a very bad signal area (2 bars if I am lucky).
I set cpu to 216 when screen off with performance governor. Also I turn off data and Wi-Fi when screen turns off.

I have mazs latest beta kernel as well. Don't really see a difference in battery life from his previous oc kernel. Ill try CPU tuner though

Sure, but be careful with it. I once it accidentally to low enough power to where I could not get out of screen off (kept going back to screen off). Also using one cpu does not work.

Does CPU tuner even work with a kernel that not over clockable?

Would, but only two cpu states will be accessible... fairly useless.
Edit: you need voltage states for intermediate voltages, then it should work. But I have never seen a non OC kernel with granular voltage definition.

Antutu battery saver is genius. on the pulldown notification it gives battery % (+battery added)
so like 100%((+30)
also clean master (which is a memory booster) doesn't run in background so it doesn't deplete battery as much as some others
Sent from my LG-P999
i installed android booster, but also procured a brand new stock battery, and i actually am enjoying about 50-60% increase in battery life... although it still is not a lot (as far as i'm concerned!) after draining it, recharging to 100%, and then calibrating, i went 7 hrs 47 mins from 100% to 50% with normal use - calling, texting, some video, some gaming. not to bad considering my old battery would only last about 3 hours or less with the same kind of usage!!!

Check out DS Battery saver. I use it on my N7, catch is, to save battery it turns off all wireless signals. It also forces the device into deep sleep as well.

Yea, if you get the paid version you can create custom profiles. It's a nice app for a tablet, but only so nice for a phone.

I think CPU Sleeper Dual Core makes the 2nd core turn off while the screen is off but I'm not sure
We tried different governor s but both cores are still on. custom kernel is kt747

2 cores on is the default for almost every Governor, excellent for Abyssplug and Pegasusq, they hotplug by themselves. Although you can turn on Auto Hotplug with any governor

If the phone is getting hot for no reason then there is something else going on that needs to be addressed. Have you looked into battery usage or checked for wakelocks?

Heat and battery consumption are related to how long the CPU runs and at what speed. Not whether 1 or 2 cores are in use. If yours is heating up, either you are using a app that requires lots of graphics and real time like a game or you have a renegade app that is misbehaving.
