Just got my OTG cable, and had an old Logitech mouse laying around....hooked it up...and it works. You see the litte pointer on the screen, all mouse buttons fully functional!

Just thought I would share this.. I dont know if anyone tried this yet.

Last night I did some testing with an OTG. My Creative Fatality usb headset worked perfectly, as did my wired Xbox controller. Using the wired controller with Shadowgun Deadzone gave me a great advantage. I found myself in the top 3 every round(many times 1st & 2nd). It played just like Gears of War.
[Verizon Samsung Galaxy Note II] SlyG07:
Can you also use a wired Xbox360 controller for Modern Combat 4?
[Verizon Samsung Galaxy Note II] Chocu1a:
I don't have MC4, but I do have MC3, I will download & try it.
[Verizon Samsung Galaxy Note II] SlyG07:
Just got my OTG Cable in today and I

cannot

use a PS3 controller for MC4; the d-pad only works for the basic front left and right movement. I cannot get it to work for the aiming *letdown*. For some reason, the Galaxy Note 2 also does not recognize my Razer TRON mouse; it recognizes it as a keyboard and so it zooms across the screen too fast. I now am using a wired basic Microsoft mouse for it and it's pretty cool and moves at a reasonable speed.

I just checked whether or not it can use my USB thumb drive and that is a go also. It has been formatted to exFAT. I can load excel files through my phone and edit them, which is pretty cool.

Overall, I think it was worth the $5 I spent on Amazon with the free shipping (Amazon Prime). I just will need to update my other accessories (USB HUB, maybe some Bluetooth devices, and a wired Xbox360 controller).

If you guys would like me to try out any other free games with a wired PS3 controller, reply to my post and/or send me a message.

Im currently running DLK7 (downloaded from sammobile installed whit odin) on my note2 can a just root it whit cwm6.zip or do I need a other cmw.zip for rooting or it doesn't mater on which firmware I am if im only use the corect model number of the phone
[Galaxy Note II Q&A, Help & Troubleshooting] ohtoulouz:
Hi,

yes, you can flash CWM from here: http://xdaforums.com/showpost.php?p=31911745&postcount=1

It is CWM 6.0.15 and the most compatible with Aroma (should you install a custom ROM with Aroma later)

If you want CMW+ROOT and flash with odin, take this one: cwm6-root-n7100-121015.rar
[Samsung Galaxy Mini] khurram6050:
here is my situation:

rooted galaxy mini with CM9 installed.

i remember when i installed this i first flashed my stock phone using odin. that process rooted it. then i installed CWM in recovery mode. then i installed the CM9 file again in recovery mode.

now i want to go back to GB. i am downloading the official rom for my country from sammobile. my query is that do i simply install that rom from recovery mode or do i again have to flash it using odin or something? also is there a way to UNROOT my mobile or not?

kindly give me a detailed procedure. i looked in the threads for this but did not find detailed info.

thanks in advance
[Samsung Galaxy Mini] Asbusto:
flash the official rom with odin and there you go
[Samsung Galaxy Mini] yackovsky:
Either flash any custom gb-based rom, or just flash stock with odin, the second option will also unroot your phone. Search on yagyagaire.blogspot.com for detailed instructions.

i did as you told. i checked for the detailed instructions from the website. i followed each and every detail. even odin showed the PASS sign. but the problem is that my phone starts then the samsung galaxy mini screen shows up. it doesn't fo further from here. its like stuck on the same screen.

kindly instruct me now what to do.
[Samsung Galaxy Mini] yackovsky:
oh man, have you wiped data and cache before flashing? since i installed custom rom on my phone i didn't even think about getting back to stock, but i know that you have to wipe before you do...
[Samsung Galaxy Mini] khurram6050:
nah, i didn't wipe the cache. ok let me try that. get back to u in 5min
[Samsung Galaxy Mini] khurram6050:
i wiped the cache and data and flashed again using odin. no errors during flashing. nut still its stuck on boot animation. what to do?
[Samsung Galaxy Mini] yackovsky:
what version of odin did you used? for galaxy mini it's recommended to use odin 4.38. here's instruction that i used to upgrade my phone to gingerbread http://yagyagaire.blogspot.ie/2011/12/how-to-upgrade-samsung-galaxy-pop-to.html#more :) just replace firmware with your region, for me it was europe :)

Hello,

I am not sure that undervolting can increase battery life. I even think it's the opposite effect

Demonstration :

Increasing battery battery life means using less power.

Power (P) is : P=U(voltage) x I (Intensity)

Most energy used by processors is converted in heating. It is like a resistance.

Voltage for a resistance is U = R x I. (ohm)

So Power used by the processor is P = U * I = R * I * I = R x I^2

So to reduce energy consumption, we have to reduce P. We cannot change R, so we should decrease Intensity.

Power used by processor cannot be change. So if we undervolt, intensity is increasing so the processors heats more and it is the opposite effect.

So why undervolt?
[Galaxy Note II Q&A, Help & Troubleshooting] EdgaBimbam:
for me undervolting isnt giving any improvements in battery life. Furthermore, cpu and gpu isnt "eating" so much power as turned on screen ;D just my 50cent

[Galaxy Note II Q&A, Help & Troubleshooting] tomh235:
Just a guesstimate here, but switching a transistor is equivalent to charging/discharging a capacitor. There is a known switching voltage for a given transistor and the idea is that within a clock cycle you can switch the transistor between states. If you lower the applied voltage (v1 to v2) it takes longer for the transistor to reach its switching voltage (vs) which is why you sometimes need to overvolt to overclock. This uses less power as E=0.5CV^2 i.e. charging the transistor to a lower voltage requires less energy.

I'm not sure how correct this is but hopefully someone can let us know.

Generally undervolting mobile phones doesn't have much effect as the antennas, and screen have a much larger effect than shaving one or two percent from the poqer consumption of an already efficient chip.

[Galaxy Note II Q&A, Help & Troubleshooting] Raphy511:
Okay thank you for your answer, but a capacitor doesn't consume energy, it is always its internal resistance. So my argument is still valid..
[Galaxy Note II Q&A, Help & Troubleshooting] liljom:
Undervolting and lower performance goes hand in hand. If you undervolt the cpu, than it takes more time to do it's job, so you don't save juice, and if you need to wait while the screen is on, than you even loose.
[Galaxy Note II Q&A, Help & Troubleshooting] SirCanealot:
Under volting does not decrease performance. Please read up in what it is. I can't even be bothered to correct you...
[Galaxy Note II Q&A, Help & Troubleshooting] G.Reaper:
And what about the reduced voltage reducing the power, resulting is less energy lost to heat? Your cpu is processing at a given clock speed, that determines the speed of the system - less heat means the cpu can run faster for longer without overheating.

Actually, I don't see how that doesn't equate to lower consumption... your equation assumes a substitution for v but doesn't consider the scaling of r with t.
[Galaxy Note II Q&A, Help & Troubleshooting] jujuburi:
I agree with Edga, the time and effort you will spend finding the correct voltage values will not worth it. Even if you find some then the increase will be around 5-6%, (that's my experience from GS2, wasted some weeks to find stable values!!) for which I am not wasting my time. Else depends on you.

And the question belongs to Q&A section. This section is for Developers and related.
[Galaxy Note II Q&A, Help & Troubleshooting] dreisus:
I'm understanding the logic but what about when the processor has no work to do. Example when Screen is off
[Galaxy Note II Q&A, Help & Troubleshooting] _delice_doluca_:
Basicly for direct current electronical devices (such as chips) P=V x I. There are 2 variables and we can only control one; Voltage.

Luckily the Voltage = R x I.

Thus I = V/R

and we can say P = V x (V/R)= V x V X R So simply the power equation is dependent to R and V.

This is how things are; we send a voltage to chip which has a constant R and it defines the current (I) with its pysical constructions (we can not change it, it is its nature) accourding to the equaiton of V=R x I. According to the power equation, since it has 2 Vs the increase in the power consumption is related to V^2, not V. So if you increase the voltage %10 this will result 110x110/10000= 1.21= %21 more power to be demanded from the battery.

Since they are nanometer sized dices they have a minimum current point to work. Current can be told as the amount of electrons to go + pole from - pole. Enough amount of electrons trigger the message in the transistor to work, rest produces heat and slowly kills the chip. However they are so small and a few molecules make difference and the manufacturer has no time to test each unit to determine the correct currents and adjust the voltage according to it. Besides it would also require unique software for each unit too. So they estimate the worst case scenerio and try to guess the chip with most faulty production and adjust the voltages including it.

This worst chip is mostly imaginary, a possibility but still they can not affort to take any risk for a few lower degrees heat and maybe 1/2 hour more battery time. Besides Android makers simply do not even care about it unlike the Microsoft or Apple pruducts. They have to make better estimations because their chips can not be under/overvolted nor OCed. This is probably why Nexus 4 has thermal issues. Google wanted to allow developers to OC easily by trusting the 28Nm build but it turned out to be a bad idea with these voltage values.
[Galaxy Note II Q&A, Help & Troubleshooting] Daemos:
Highschool level physics should tell you undervolting increases battery life...by how much...who knows.

The goal is to reduce the amount of watts the device consumes.

Power (W) = Voltage (v) * Current (amps)

Now the problem with this formula is we cannot use this to estimate on non constant variables, as we can adjust voltage, but one also must think amperage is also changed, so we need to get a formula that includes resistance which should be constant.

P = IV, V = IR, I = V/R so using some basic arithmetic we can get the formula (I'm not going to show the work)

P = V^2/R

As you can see reducing the voltage, has an exponential effect in reducing power usage...

So say we go from using 1.3125v (which is my stock at 1.6ghz) to 1.2v.

At 1.2v it will use only 83.6% of the energy compared to what it needs at 1.3125v to do the same job. This equates to an energy savings of 16.4% again this is only for the processor.

Undervolt the GPU, then the memory and internal voltage...it can all add up.

Edit...I see _delice_doluca_ has already posted a good explanation...I should of read the whole thread first :p
[Galaxy Note II Q&A, Help & Troubleshooting] Zanr Zij:
The truth - my and many others experience : more than 1/2 hour sreen on and lower temperature. Silicon/transitors/chip love low temperature. At lower temp, transitor can work at higher speed. Don't you want more speed and still have good battery life + temp?

For me, the time finding stable volt = reasonable. I spend max = 1- 2 days to find with difference kernel!

[Galaxy Note II Q&A, Help & Troubleshooting] Raphy511:
I agree with you, but my demonstration on first post is also true ! So why is it opposite...?
[Galaxy Note II Q&A, Help & Troubleshooting] garyd9:
Was this moved into dev discussion from elsewhere? (If so, can the person who moved it please PM me?)

Regardless, the OP seems to be making things more complicated than they need to be - and is also making an incorrect statement.

The overall power used by the processor CAN be changed.

The effect is similar to running a gasoline (petrol) engine with an overly rich fuel/air mix (which is usually done by most car manufacturers to compensate for poor fuels.)

Once you take into account that the power isn't fixed for a given speed, you can see that voltage can be reduced without raising the current - and has the effect of LOWERING (not raising) the heat resistance. (R=V/I - so if V is lowered and I remains the same, R must drop.)

That being said, the real-life impact of under-volting is usually negligible when compared to the overall drain of other aspects of the device (such as the radios and screen.)
[Galaxy Note II Q&A, Help & Troubleshooting] edwinpang:
Power = voltage^2 / resistance

So lowering the V of cpu there is a squared decrease

Resistance is constant mostly
[Galaxy Note II Q&A, Help & Troubleshooting] AndreiLux:
You are all in the wrong category of electronics, I or current does not exist as a constant in transistors. Semiconductor physics are different from normal macro-electronics. The same principles still apply but they are meaningless as their magnitude are lowered to nothingness.

Main power dissipation and power consumption is caused by dynamic leakage on the transistor gate while it is switching. Secondary power consumer is static leakage caused between gate and the body.

The usual simplified formula for CMOS transistors is expressed as

Power = Voltage² x Frequency x Capacitance

or

P = V² x f x C

That's basically it in very simplified terms. And as ewdinpang said, lowering voltage has a squared power decrease in the dynamic leakage power. This has been measured and proven, from myself included.

The full expanded forumula is here:

This is a nonsensical argument, temperature aka heat, is power. If you are getting a less heated phone, then your battery life is improving. If this wouldn't be the case then you are holding the solution to the world's energy problems in your hands.

*Nerdgasm*

I think....I Love you
[Galaxy Note II Q&A, Help & Troubleshooting] Entropy512:
This is where your post completely falls apart. P is NOT CONSTANT.

R is semi-constant (semiconductors are weird, so can be nonlinear), gate capacitance C is constant.

If you lower V, you lower I, and thus, you lower P=V*I

That's the whole point of reducing V...

And now I will be reporting this thread because it doesn't belong here. This is not in any way development discussion...

Edit: In general, UV is best for, on most devices, 3-5% reduction in CPU core power consumption before you hit stability limits. For general day-to-day use this results in less than a fraction of a percent of total system consumption being saved, but can matter if you're a heavy gamer, giving you more headroom before hitting thermal throttling and consuming less power.
[Galaxy Note II Q&A, Help & Troubleshooting] @rbiter:
I don't know what the big deal is. At the very least with undervolting you are reducing the heat which has benefits of longer battery life, cooler phone in general, battery will heat up less. Keeping your silicon and battery cool are more important for longevity rather than 3-5% general extra time gained. Best case scenario but far fetched is ~10% but it is all hard to quantify since your usage today will still be dramatically different no matter if you have the EXACT SAME ROUTINE to a tee. The variables autobrightness alone are one, but cellular and WiFi reception another major factor.

My first Android was the S3, and now the Note 2. Both phones i had undervolted approx -100 mV to -150 mV, And each time doing so made a massive difference. So all who are saying that undervolting does not help save battery, you cant be more wrong.
[Galaxy Note II Q&A, Help & Troubleshooting] retrorom:
First of all, I tried to understand these posts, but honestly I didn't get much out of it. I was reading this thread because I was wondering if overclocking would be more efficient when overvolting slightly. Usually I slightly undervolt and overclock my phones a little, but would the result (of performance) not be better if there was a very minor overvolt? I was reading this and that is why I ask my question.
