theres a reason that not many people know about it. noobs dont know what they're doing, and those that do, know not share setttings. not hard to UV, and those that find it hard, are probably best of not messing with it

I can make a guide on how to turn a vaccume into a sort of gun, but sharing it publicly is not recomended

I understand your want to help the community, and thats good.

Is this better? I removed my frequency's but explained myself. Think of this as a test to see results now. It also has a simple guide that isn't beating anyone with a bat.
[AT&T Samsung Galaxy S II SGH-I777] jthatch12:
Well as you start to involve capacitors and inductors the law becomes slightly more complex, involving real and imaginary components :-P. the reason why the phone at lock up may be due to the capacitors and inductors. These values are very sensitive to the current in the circuit! Changing it slightly may give undesirable results. Long story short. Undervolting by small amounts will have a negligible difference in battery life. Undervolting by large amounts will screw with how the circuit was designed. So be careful!

Sources - me being an electrical engineer!

EDIT: One last thing karate made me realize, decreasing the voltage would require increase current. (Since the values of L, R, and C cannot be changed! if you guys really want to save battery just stick to underclocking, you don't know the circuit configuration and specs of the phone.
[AT&T Samsung Galaxy S II SGH-I777] karate104:
So does undervolting really offer no battery life savings? I've read an article on laptop undervolting offering significant battery life improvements, especially because the CPUs run at lower temps thus saving life by requiring less fan cooling. I guess that doesn't apply to phones because we don't have cooling fans, but is there really no reason to undervolt?

Also, why would underclocking offer more battery life?
[AT&T Samsung Galaxy S II SGH-I777] jthatch12:
Lower CPU usage= less power consumed

I generally uc to 800mhz, and see a noticeable difference.

I've tried UV as well, but never really noticed anything significant.

hi fellas

well, I got this issue from the very first time I used the galaxy tab, when I setup a new email on my stock email client witch I think it's awesome, I get instantly 25 unread messages witch are not unread. any thoughts about this and how to get ride of it without checking them one by one.

Hi,

I have a rooted official ics neo V with locked bootloader, I've noticed recently that its not saving ringtone message tone or notification tones, and ever time I try to access the music player it tells me I have no music in library, I have a 16gb class 10 filled with 8gb of music, I can still browse the music folders with a file explorer...

Any ideas what could be wrong.
[Sony Ericsson Xperia Neo, Pro] aqshyt:
Try the Xperia S music player app.

Check this:

Install SemcMusic.apk and MusicWidget.apk (you can install other apps too, all work fine)
[Sony Ericsson Xperia Neo, Pro] darn02:
@aqshyt Thanks for replying, i did what you said and no joy, same problem, I wanted to avoid it but I'm just going to do a complete fresh reinstall, plus format of the SD card, thank god all my contacts are sync'ed with Gmail.
[Sony Ericsson Xperia Neo, Pro] aqshyt:
You can also back up your contacts on the memory card, save it to your computer, then put it back again after formatting your memory card to import then.
[Sony Ericsson Xperia Neo, Pro] darn02:
I've done a full fresh install, contacts sorted, I'll use it today and see if it keeps my tones and music library, fingers crossed, it might just be placebo but my phone seems faster.
[Sony Ericsson Xperia Neo, Pro] aqshyt:
Good luck B-)
[Sony Ericsson Xperia Neo, Pro] darn02:
So it seems that the neo v can't handle 8gb of music, phone works fine until I transfer 8gb of music to it then is loses tone settings and drops the library, I moved my tones into the system/media/ folder and that solved the losing ring tones problem, but it still drops the music library, I think I'll have to cut my music down to 6 or 4gb of music, which is gonna be tough because I really like my music it was hard enough choosing 8gb worth.
[Sony Ericsson Xperia Neo, Pro] darn02:
After putting 2gb of music on my phone it works fine no clearing of ringtones or dropping of music library, I still don't know if its the phone or memory card that was the problem, my last phone was the X10 Mini Pro and I had 8gb of music on it and it worked fine, so I think its the phone, anyway its sorted now.
[Sony Ericsson Xperia Neo, Pro] chefnoob:
Did it happen right after you installed some mp3's?

I downloaded a faulty mp3 before and it caused my music player to act weird. You can try not moving the most recent songs you had to start eliminating it. I dont have that much songs on my phone but I do have more than 16gb of media on it and im not having any problems.
[Sony Ericsson Xperia Neo, Pro] darn02:
I was using the same tracks that I had on my x10 mini pro, so I 'think' the tracks are fine, unless maybe there was a corruption when transferring.
[Sony Ericsson Xperia Neo, Pro] Madfysh:
that, or corruption of sd card itself..

Does anyone know if there is an official 2m USB cable available in the UK? I bought a generic one off eBay, but it charges the phone extremely slowly....
[Sony Xperia P, U, Sola, Go] anthon:
I use the 2m cable that came with my kindle 3 and it works as well as the original one
[Sony Xperia P, U, Sola, Go] deadsea:
Are you charging the phone from a USB port? If so, it's the limitation of the port, not the cable. Try with a proper charger an it should charge at a more sensible pace.
[Sony Xperia P, U, Sola, Go] Efe64:
Dealextreme dot com
[Sony Xperia P, U, Sola, Go] Ambroos:
Charging speed doesn't depend on the cable but on the charger it is used with.
[Sony Xperia P, U, Sola, Go] Rabangus:
I'm afraid it doesn't work as well for me. I got a Kindle 3 cable, and while it does charge the phone (using the charger which came with the phone), it does it very slowly. So slowly that if I try to use the phone even for basic tasks whilst charging with it the battery still keeps heading south.

If I use the stupidly short cable that came with the phone it charges nice and quick, but every other cable I have used so far either doesn't charge or does so very slowly.

Any ideas as to why this would be?

On a related note, this sounds good, but again the cable looks stupidly short:

[Sony Xperia P, U, Sola, Go] BigPhil:
What are you using to charge your phone? An EP-800 or something else? I have a cheap 1500ma charger that seems to take ages to charge my Xperia. The cause was that for a full speed charge, pins 2 and 3 must be bridged. I dismantled the charger and put a tiny blob of solder on the usb port pins. It now charges like a demon.

Same story with my car charger. Before the mod I could actually lose charge when using satnav and streaming music over bluetooth.

I have a battery widget that says whether I am on AC charging or USB charging. Its name eludes me.

Oh, and a safer alternative may be to sacrifice a USB cable and bridge the pins on that.

Better than all those though is the official Blackberry Playbook charger. 2A and a long cable. Charges the phone like nothing else.
[Sony Xperia P, U, Sola, Go] Rabangus:
Yep, am using an EP-800.

Fortunately the latest cable I ordered works a treat, so I can happily recommend this one:

[Xperia Play Q&A, Help & Troubleshooting] Android Is ReadyTo Play.:
Hi everyone. Im happy with my stock (doomlord kernel , some tweaks) and battery life seems good. But some people says Jokawild 3 better than stock. But i think stock is better. Because i used Jokawild 2 days and battery drained very fast. What do you think Xda Family ?
[Samsung Galaxy Nexus] grivad:
Loving my GNex, however I've only had it a couple weeks.

There are several kernels out there, and from comparing all of them and reading all the threads as much as I can, they all seem to have relatively similar features... I'm having a hard time picking one.

Is there someone who can clarify the differentiating features of each kernel? Are certain kernels better suited for different ROMs? Do certain ones have compatibility or other persistent issues?

Mainly:

faux123

franco

GlaDOS

jamesbond

Trinity

I've tried faux123 015m (loved faux's kernels on the Sensation, but I had some mobile data issues with it on the GN) and Trinity (latest seems fast/stable, except the color profile was messing with me). I'm trying GlaDOS now. Again, though, I'm not sure what advantages or perks one kernel flavor gives me over the next. Can anyone shed some light?
[Samsung Galaxy Nexus] blowtorch:
I have tried them all myself at one time or another and i always come back to GLaDOS. I chose to run this because of the unique and innovative features Ezekeel has developed plus the great battery life. BLX, Vibration control, Touch Wake and of course the Wheatley Governor which was developed for this kernel to give the best performance and battery life, which in fact it does. The GLaDOS control app is great too and Ezekeel is always updating and making it better.

GLaDOS is exclusive to Rootzwiki that why you don't see too much mention of it here unfortunately ... I'm not even sure if Ezekeel lurks around here anymore?
[Samsung Galaxy Nexus] masully84:
Leankernel for me
[Samsung Galaxy Nexus] WiredPirate:
I noticed he released a control app, I may give it a try!
[Samsung Galaxy Nexus] zephiK:
franco
[Samsung Galaxy Nexus] grivad:
Thanks for your responses!

However it looks like people are just posting what they use. What I'm looking for is information on what differentiates each kernel.. what is each kernel's "claim to fame"? From what I've seen, all of the kernels' features look pretty similar.

For example, "X kernel balance performance and battery really well. Y kernel reduces the voltage to the screen to further battery savings. Z kernel is more focused on performance. A kernel allows your phone to make popcorn." etc.

Or are they basically the same?

Thanks blowtorch for giving some information as to what differentiates GlaDOS from the rest :)
[Samsung Galaxy Nexus] @rbiter:
Jamesbond will likely give you best battery life and stability. He has a couple of other kernels with some performance boost. Glados was buggy as hell and some other things but that is for you to decide. Other kernels for me were kind of meh. I honestly dont understand how so many people say this kernel or that kernel is the best or best on battery life when so many tweaks in X kernel add more performance at the cost of mah. I liked glados and its features a lot but it came at a cost too high. Touchwake is a really nice feature in it and i am surprised more people don't ask for it. Another kernel i liked was bamf paradigm but i am not using it. I would like to try that rom again in the future but it wasnt ready for me personally. Havent tried franco's at all. Just seems to be feature packed kernel but for what?
[Samsung Galaxy Nexus] msedek:
I like francos so far works great with my favorite rom AOKP, buttery smooth, stable as hell, you can go battery saver or performance since you can OC/UV, etc, if you buy the App in play store it works great cuz he updates the kernel oftem and you can use either milestone versions or nihgtlies, and has the option for autodownload and autoflash the lastests updates.

You can change screen color values, as i said oc/uv, change the boot animation, and plenty other stuff..

Thats my 2 cents on your research

Edit: forgot to tell you, he also has a support mail , and if you have any issue kernel related he will answer with a solution if possible.. Report bugs etc
[Samsung Galaxy Nexus] msedek:
Sorry miss clicked and double posted :mad:
[Samsung Galaxy Nexus] blowtorch:
GLaDOS has been bug free for at least the last 5 revisions
[Samsung Galaxy Nexus] @rbiter:
Really? Then where is all that code he thought unnecessary but needs to go back add in?
[Samsung Galaxy Nexus] @rbiter:
And the speaker crackling randomly or playing when it feels like it? Or the extremely slow refill ratemoccasiinally?
[Samsung Galaxy Nexus] blowtorch:
I really don't know what you are talking about there unless its the bluetooth drivers that were re-added a few builds ago?

never seen any of these problems ...
[Samsung Galaxy Nexus] grivad:
I've been using GlaDOS for the last couple days and haven't had any of these issues. Bluetooth is working perfectly, even over my car's hands-free setup which has been problematic with some kernels, and audio is working perfectly... maybe you were on an older build?

Anyone have any other info? I'm surprised nobody has said anything about faux or Trinity..
[Samsung Galaxy Nexus] hev88:
Well I guess I'll be the first to represent faux kernel over here. Like that its not over done and no special app is needed to control it and the gamma control from panda board he forward ported is pretty slick if you ask me ;)
[Samsung Galaxy Nexus] blowtorch:
Trinity is legendary ... never got around to faux

I'm sticking with CM9 Kernel for now it's as good as the rest IMO plus they are integrating more and more into it ... missing touch wake though from GLaDOS, oh well

I'm mainly looking for battery life now. I don't really notice much difference between most of these kernels in terms of battery life. All of these kernels have good performance without overclocking.

I find that i bounce around from kernel to kernel and in the end when all is said and done no kernel is better than the other and it really comes down to preference.
[Atrix 4G General] mandroid717:
my Atrix was flying before i had to send it in for warranty work a few weeks back. (digitizer) Antutu scores around 7000. the rest of the benchmark tests where pretty high also. When it was returned i immediately unlocked the bootloader and rooted it. Now my scores from Antutu are 4500 at best. I am using the exact same rom (Neutrino), and kernel (Faux123) as before. I have tried other roms (cm7 nightlies) reinstalled and full fastboot wipe many times but still the same outcome. The only difference i can see is that i used an different method to unlock the bootloader and root the second time around. Do you think the some of the permission where affected differently the second time around. Am i just overlooking something?

HELP!!!!!!

[Atrix 4G General] DroidRunner:
Is the phone actually slower? Or just scoring lower scores?

[Atrix 4G General] mandroid717:
the phone actually feels slower. more laggy when it comes to videos, games, scrolling through menus. my fps scores are all lower across the board in any benckmark. yes i know they mean nothing but when the scores are that drastically effected there is an issue i believe.
[Atrix 4G General] Bruce Lee:
I have heard that refurbished phones USUALLY don't perform as well as the brand new ones do. Here is my example, a refurbished Atrix I read from some users can't even sometimes boot a custom kernel when the custom kernel is around 1.45 to 1.6. For example the one kernel that the dev clemsyn. I saw a FEW mention that when they said they had a refurbished Atrix.

Sent from my Atrix with XDA Premium
[Atrix 4G General] tobnddl:
There is a "Boost.sh" script included with Neutrino (I believe in /system/etc) that Notorious recommends be run when you get that "not so fresh" feeling. It is a defrag tool that can be assigned to a widget and should be run every so often.

Also, you will want to see if "Nitrocharger.sh" in the same directory is running as Root at Boot. I have seen big improvements by implementing this.

Both of these scripts came with the ROM, so hopefully you have fast access to them. Good luck to you!
[Atrix 4G General] mandroid717:
thanks for the info fellow xdaers,,,,,
[Atrix 4G General] plemen:
Actually I had the opposite experience. My original phone wouldn't boot with the clemsyn kernel. My digitizer bombed and I received a refurbished unit from repairs. The new unit runs the clemsyn kernel just fine. So I guess it's just the luck of the draw...
[Atrix 4G General] sathelate:
As tob said, those "so verry little script" can makes big differences sometimes ;)

I would like to add my personal toughts, for me, the ROM actually scoring higher and higher and feel a litle bit more freshier each week past within the ROM... so my thoughts would be, the cache partition, the more longer the rom is implemented, the more score you'll get cause the cache slowly become bigger and bigger giving you full power to open something tough!

As for the battery, from my experiences, you can't really judge a battery life while you just flashed a rom, you got to wait until the first week to see if there a big changes between the other ROM you came from ... so my guess would be, those scripts and the longer the ROM is implemented on your phone, the more fast and stable it will get, and you will feel the power slowly coming out again!

My bad if I'm completely wrong, but it is my guess!

Hood luck with your "new" phone :)
[Atrix 4G General] mandroid717:
i brought up some old Antutu scores and notice that my ram. cpu integar and floating point scores are extremely low. i have tried multiple kernels but still no change. now i am even more confused......doesn't take much. could it be that my cpu is locked so i can not overclock. it kinda feels like its only utilizing one core.

My question is why does it matter if we have root? God forbid we want to remove Verizon Crapps and feel like we own our phones. It's the same with AT&T not allowing any type of unlocked phone on their network.
[Xperia Play General] lightningdude:
If you remove the Verizon apps, that's less of an opportunity for Verizon to make money off of you. They also talk about security issues, which I can actually see a point to it. After having had my father destroy a computer by deleting system files and registry keys, I believe that root access in the hands of the technologically illiterate could be devastating.

However, that's why they can claim that warranties are voided, because it was something we did to mess it up. Frankly speaking, it's business. They pay people to develop these apps, and the OEMs pay people to make the user interface, which I'm sure is why they like to lock the bootloaders. In other words, companies like to make money, which means they're going to try their hardest to make sure they have every opportunity to.

[Xperia Play General] jjalbert:
I have the same issue. Called Verizon to see if it was part of the update, they called Sony "who could not tell" but said "if everything is working, dont worry about it."

I had the Verizon 2.3.3 firmare, and rooted with zregRush. Before the OTA I read that it would fail with root, so I unrooted the phone. Started having a couple issues, so minor I do not remember what they were, but ended up using flashtool to reflash the stock image I downloaded. Everything was fine then, my icons were turning green when connected, and all. Then did the OTA, and everything is working but the icons for wifi and 3g never go green. Is there any more word on this? Is there any futher word on zeregRush rooting?

I have the doomloard linux script to to the root process, and I tried to run the commands instead of the script, I found that I was unable to create or pus files to the device, so I tried to use the sdcard, but when running the zregRus program all I get is access denied!
