May have to look into purchasing one
[Nexus S Accessories] method2madness:
Yeap. Definitely worth looking into. ;)
[Nexus S Accessories] apreichner:
I bought two. The one for me and one for my girlfriend. Hers doesn't light up at all for some reason but it still charges, mine has the blue light but I actually kind of like it.
[Nexus S Accessories] method2madness:
Looks like the price went up $2 to $5.89. Weird. Still a great deal, tho.

Anyone else not able to send MMS when roaming? I have full roaming data through Verizon using the browser and other apps. For some reason it won't send/receive MMS though and this is in areas where I was previously able to use MMS on both my Epic and my Evo. Any ideas would be a great help
[Motorola Photon 4G] my2cents:
I had the same issue at the lake. I was trying to send some pictures of my kids and it would not do it because I was roaming. However, I could email them. I was never able to figure it out.

EDIT: Like you, I was able to send a mms while roaming from the same spot with my Samsung Moment. Here is another thread to read through, but no real answers. :(
[Motorola Photon 4G] ianford10:
Do you need to add another APN for your MMS?

On o2 in the UK we have to add two apn's, one for data and the other to enable sending MMS's.
[Motorola Photon 4G] my2cents:
How would we go about doing this?
[Motorola Photon 4G] ianford10:
Goto Settings > Wireless & Networks > Mobile Networks > Access Point Names > Hit settings button > new apn

[Motorola Photon 4G] piaa_nissan:
No option for addding APN on mine :( Ive tried pulling the MMS proxy settings out but that didnt help. Cant seem to find the right place to edit the current APN either....
[Motorola Photon 4G] ianford10:
Not too sure if I read correctly in another thread that adding another APN is blocked with certain networks, cannot remember if I just dreamt this or not.
[Motorola Photon 4G] iLLa:
I didnt have the APN setting either. The MMS isnt working over wifi.
[Motorola Photon 4G] djmiked:
I have the same problem with the Photon. I had no problems with my previous phone sending and receiving MMS while roaming, but I can't do either with my Photon. Sucks too because I am roaming all day at work and when people send me an MMS it doesn't even let me know because I am roaming. I usually find out at a later point while looking through Texts that someone sent a MMS.
[Vibrant Q&A, Help & Troubleshooting] divertedmind:
I use Vibrant on the AT&T Network.

Recently I've been usin MIUI and Revamped flawlessly. They've been great.

Friday night MIUI (1.9.16) SS-6 came out, I was excited and did a full cache wipe+dalvik+factory fixed permissions and flashed. Went smoothly, no hic-ups, booted up and was happy. As I went through the day tho, I found out none of my SMS texts were going out. I would recieve but no one got any of my replies.

Strangely though I am able to send MMS messages. I know that they go out different ways so that would explain that.

I can make an recieve calls as well.

I've tried going back to SS-5, trying out LE-9, and Stock MIUI. (The current release and one previous.) Sadly the same result being unable to send SMS but able to recieve.

It does not have a continuous "Sending Status" it reports the messages as sent. With a timestamp.

Also tried sending from GoSMS, same result. I don't know if this problem has ever happened before.

Help is greatly appreciated.

I will be getting my Sprint SGS2 on Monday. I'm coming from an EVO 4G but I've rooted both a Mezmerize and a Droid Charge as well so I do have some experience.

I was, however, wondering if there was anything special that would need to be done for the carrier specific devices. Namely, for WiMax keys? Am I allowed to just flash any ROM that is posted? Will the current root methods work?

Doesn't SetCPU (or any other app for that purpouse) do exactly that? If you set scaling and min/max freq. accordingly? What is the difference beetween that and setting in manually?

[Galaxy 3 Android Development] DaBigFreak:
Hm, a guy called Kyrillos told me, that normal voltage at 667MHz is 1200mV. So, in newest g3mod, from 500MHz on, its higher, at 800MHz its already 0,1 volt above max in stock.

So how dangerous is it to let it allday at 800Mhz@1300mV ?
[Galaxy 3 Android Development] dhirend_6d:
He s a recognized developer. :) A very good one infact. He was right by the way. Its only the faulty reading.

---------- Post added at 01:32 PM ---------- Previous post was at 12:54 PM ----------

Hillbeast excellent, excellent info. That s the precise reason I don t use high overclocked kernels. Maximum I goto is 800MHz.
[Galaxy 3 Android Development] mrvek:
Yes. I use it mostly. Other devs and experienced users here as well for what i've noticed. Or conservative which saves battery because it scales freq more gradually. http://www.setcpu.com/ - http://www.setcpu.com/#7

And profiles, especially the Temp and screen off. Prevents from overheating and exscessive battery discharge, respecitvelly.

Probably very. But overclocking in general shortens life span of electronic components, primarily because of increased heating. If that worries someone that it is probably best not to overclock at all.

I personally see no difference between manipulating cpu freq manually or by using some app to do it when necessary. If I'm wrong then please feel free to elaborate.
[Galaxy 3 Android Development] hillbeast:
I will update this thread and I hope it will actually get stickied as it's quite important information in my opinion and it could save some peoples phones.

SetCPU will obviously set the max and min settings, but in an ideal situation you will want to have a mild overclock (or none at all) if you are just using for phone for normal functions such as TXTing or browsing or something like that, but SetCPU can't detect when you are wanting a more intense operation such as a game, so you're best to adjust it when you are needing it and switch it back.

I keep a SetCPU widget on my home screen to do that.

The stock voltages for our phone at 667 is 1200mV, yes. At 1300mV you will notice a mild increase in consumption.

If we follow the same algorithm in the OP:

OC Wattage = TDP * ( OC MHz / Stock MHz) * ( OC Vcore / Stock Vcore )^2

We get (again, assuming the standard consumption is 100mA) 100 * (800 / 667) * (1300 / 1200) = 140mA. Yes, it's higher but not too much higher. If you UV it by 50mV @ 800MHz you'll go to 130 and at 1200mV it'll be 118mA.

Overclocks like this are still not 100% safe, but they are nowhere near as dangerous as a 300% power consumption increase.
[Galaxy 3 Android Development] ahsanaimad:
This is the Information I was looking for past 2-3 weeks. Finally you posted it here.

Thanks hillbeast
[Galaxy 3 Android Development] Jeegsawk:
Hey man. I really appreciate your effort to inform. I just would like to add something.

Overclock: in modern cpus power consumption increases almost linearly with clock. Let us say linearly to be safe. It means double clock double power (and so heat)

Voltage: when you increase the voltage the power increases approx quadratically (double voltage for times power). But also higher voltage means stronger signals in transistors and so higher stability.

Heating and lifetime: the heat decreases the lifetime of electronic components but not in a linear way. Please also note if a circuit does not die very soon (infantile mortality) it will last very long in normal conditions. So even if it was cut by half starting from the normal 10 years expected lifetime it would be anyway long for a phone.

So it is clear voltage is much more important than clock for power consumption. Decreasing the voltage you could have an overclocked cpu which consumes and hests up less than the stock one. Of course it is less likely to be stable.

Personal computer cpus needs cooling and are difficult to overclock because they become very unstable when overclocked so you have to increase voltage.

Finally to be clear I want to repeat your lesson.

DO NOT OVERCLOCK UNLESS YOU REALLY KNOW WHAT YOU ARE DOING. and don't complain with developers if your phone will break.
[Galaxy 3 Android Development] tadeas482:
After reading this, I will never overclock more than 1GHz. Thanks :D
[Galaxy 3 Android Development] apollo5801:
I agree extreme 200% overclocking is harmful to cpu and disagree with some of the points.

I don't think wattage and tdp formula are correct. If it is correct in reality battery should drain in 1/3rd of the stock time and should heat up immediately. we are just increasing the power supply in mv which is 1200 to 1500%. That means 25% power increase.

When the phone is in idle (no music, wifi, data ...) mode cpu/armcore is completely turned off. That means no frequency, no power supply and no heat. Other peripherals have separate clocks and they will keep running in idle mode. This is the difference between desktop and phone cpu.

frequency is 'no of times turning on and off transistors in a circuit per second'. In fact cpu's are designed to work at much more frequencies than stock. But stock frequency is decided by considering various operating conditions worldwide and $$. Personally i use 1020Mhz and phone operates like stock frequency.
[Galaxy 3 Android Development] gianpa:
I don't agree with one of the last statements:

Assuming you use setcpu, your phone spend most of the time in standby. if you use your phone a lot, it will be in standby 70% of the time.

Assuming that when your phone is not in standby the clock is automaticly set to 1400 (which is probably not, but we're doing worst case), your phone will be overclocked 30% of the time.

If your statement about battery drain is correct, the processor will use 160% more battery than usual. This, will not result in a huge battery drain, because actually, the processor is draining very little battery compared with things like display, wifi, 3g and so on.

If your statement about lifespan of the cpu is correct, the lifespan of the cpu is reduced to 75%. Considering that a cpu can last years and that you usually throw your phone away way before the cpu stops working, doesn't seem like a big deal to me.
[Galaxy 3 Android Development] mrvek:
That is true. Unless you run your phone 24/7 at max OC speed and phone heats up excessively there really should not be problems. That's why we have good apps and scaling governors that save the cpu and battery. In my case the phone spends most time at 400Mhz, then on 800, then 1400 then other freqs (based from setcpu report - info → time in state). Main profile beeing 400/1400, ondemand. And temp doesn't go over 31°C on daily use. What increases temp are mostly games but for that i use several setcpu profiles (in this point i disagree with hillbeast and the ability of setcpu to know my specific requirements. I know that it can't know what i need and when but if I set manually the requiered freq (max) to play a game the phone would heat up significatly (angry birds for about 30 mins gets me to 36°C - relatively high). And then i need profiles not to overheat the phone. And now when I already have profiles, why not let everything be automatic?).

Please don't get me wrong, I agree that OC-ing is quite risky and it should (must‼) be done with great caution and that is an implicit requirement.
[Galaxy 3 Android Development] umangsagar:
nice effort....well its the classic e.g. of we wanting everything at least possible cost :)....i really appreciate the efforts of people here to have developed such kernels which allows OC to such levels, check other forums and u will find least Kernels which are OC to over 200 or nearby percentages.

However, as I use SetCPU with 200 to 1200 Mhz, Ondemand Governor and making sure that SetCPU is not on SD but in internal memory to avoid delay in loading as after boot it takes a while to scan the SD Card and has got onboot option selected, that does the trick for me and i utilize the juice and when required. No one can precisely tell to what extent it will reduce the life, but I am conscious it will and must have some reduction, a cost we must be ready to take for better performance...fair tradeoff I would say.
[Galaxy 3 Android Development] Kingzak34:
I've a question, if we overclock our phone ( I use Dualboot 1300Mhz version with 1300 perf when screen on and 667 perf when screen off ) and it don't go heat (just normally) is it dangerous ?
[Galaxy 3 Android Development] SRT_:
Well, yes it is, since you use the performance governor on 1.3 GHz... The performance governor makes sure your CPU is clocked to that frequency the whole time your screen is on... Plus, a 200% overclock as described on the first post means a lot of stress to the CPU as well as increased energy consumption... Also, 667 MHz on screen off with the same governor is useless, as the only thing it does is drain your battery for no reason... The frequency your phone needs to wake up (turn the screen on) is around 200 MHz... I recommend deleting your profiles, and setting via SetCPU min. frequency 200 MHz and max. frequency 1300 MHz on "ondemand" governor. This governor makes sure the CPU uses as much power as it needs to keep the phone running while the screen is off, and as much power as needed to run a task adequately while the screen is on. You get a great balance between CPU damage, power used, and performance without having to take care of anything as the phone takes care of itself... Hope I made this clear... :)
[Galaxy 3 Android Development] Kingzak34:
I set 667 Screen off cause sometimes phone take time to unlock the screen, it react slowly when it's set at 333 and sometimes music get slow sometimes when screen off too ( I've 166 / 333 / 667 / 866 / 1020 / 1300 frequencies )

What's original stock gouvernor ? Conservative ?

And my battery can up to 2 days like on a stock non OC ROM/Firmware :)

... So, I'll use 333-1300 Ondemand with Upthreshold 95% and Power save Bias : 100

If you have most recommendable advanced settings ? :)
[Galaxy 3 Android Development] kyrillos13:
Try: on demand 166-1300 Mhz, with a screen off profile: On demand 166-667. You wont have problems :P And optional, try undervolt -50mV to all frequencies.
[Galaxy 3 Android Development] hillbeast:
No, that formula is correct and has been tried and tested by overclockers for years. The battery doesn't drain 3 times as quickly because the CPU is not at full speed all the time. I said that it uses 3 times as much power at 1400.

Also 1200 -> 1500 is not a 25% increase, it is a logarithmic scale on voltage increases so it works out at more like 50% increase. I have a Celeron D that uses over 3 times as much power simply by overvolting it by 0.2V.

Yeah I acknowledge this, but I am more pointing out that when it's at full speed it is extremely hard on the CPU to be at 1400MHz. I'm not pointing out reduced battery life, rather pointing out the CPU lifespan is lower.

The point of this thread is not to scare people away from overclocking, I'm simply saying that people need to be very careful with it and need to be aware that a 24/7 overclock is not necessary.

A good analogy to make is Intel TurboBoost. We don't need the extra 300MHz it provides 24/7 and if we were running it faster all the time, then the CPU would run hotter. Instead, it runs at full speed 24/7 and then full speed + a boost when needed.
[Galaxy 3 Android Development] apollo5801:
You can not use desktop formula for mobile processor. Except the name CPU everything else differs in desktop and mobile processor. I am sure the length of the desktop cpu circuit and transistors will be much more larger than the mobile cpu and because of that it sucks more power. I am going by the reality we are experiencing. In my overclocking i did not change cpu code and governors. So it works the way stock frequencies work and i still same battery life at 1020Mhz full speed and 1400mv. I did not understand logarithmic increase.
[Galaxy 3 Android Development] hillbeast:
It doesn't matter what platform the processor is on, as this isn't a formula for specifically desktop CPUs, it works for anything integrated circuit on any platform. Increase the voltage of an integrated circuit and it will increase the current drawn.

V=IR (voltage = current x resistance) is the formula for calculating current (based on Ohms law). The resistance of an integrated circuit remains a constant (provided the temperature does not alter the resistance, however with increased temperature, resistance will increase). If you assume R (resistance) = 1, the formula for current is I=V/R. 1200 / 1 = 1200, 1500 / 1 = 1500.

If we then take P=IV (power = current x voltage) (some people say this doesn't always work, but that is for AC circuits. It is 99% accurate for these purposes), 1200*1200=1440000, 1500*1500=2250000. That is NOT a linear scale. As voltage increase, the current and power consumption is increased exponentially.

It doesn't matter what method is used for overclocking the CPU. If the voltage increases, the power consumption increases dramatically as well.

Additionally, this doesn't happen much, but as the temperature increases of a transister it'll become less efficient. It'll draw more current, so as the temperature of an overclocked CPU increases, it'll become even less efficient. This is why they use liquid nitrogen to do extreme overclocks: to elliminate this resistance.
[Galaxy 3 Android Development] apollo5801:
This is correct only for strait wires. Not for circuits. On off signal goes in to the circuits and power varies. We are not assuming here. Look at the overclocked battery stats. If the exponential power is right image how long battery runs.

Overclocking method matters because voltage changes with frequency. If you can do this test. change frequencies to stock in fugumod/g3mod and compare how frequency is changing between stock and custom. I tested my self and phone remains at high freq for longer time than the stock.
[Galaxy 3 Android Development] hillbeast:
No, this formula is for calculating anything between point A and point B. It doesn't matter what is in between there, as long as there is no power source the formula always works. This can be used for calculating an entire computers power consumption if you wished.

No because no matter what overclocking method is used, the power consumption will remain the same. That is like saying that if you fill a bucket of water and tip it in the toilet, it'll use less/more water than if the bucket of water is already in there.
[Galaxy 3 Android Development] Dharam_Maniar:
well, it maybe because the code of the governor's is also changed...
[Galaxy 3 Android Development] myhayserano:
Currently i'm using g3mod 1.8 ultimate kernel cpu clock set as 200-800mhz ondemand , screen-off profile 200-400mhz ondemand and a little undervol like this:

-for 600,400,200 def is 1200mv and i run at 1150, phone is stable.

My question is: there are any side efects of undervolting, my phone is responsive and i do not get any freezes at all, battery life is ok no hazardous drains, 2days medium usage.

Alien-SG3-ware
[Galaxy 3 Android Development] hillbeast:
Undervolting a CPU has no negative side effects except for causing it to become less stable if you set it too low. If you can undervolt it, then do it. It'll save battery power (even if only a little) and will extend the life of the processor.
