[Galaxy S I9000 Accessories] paddyb:
My GF ran over my mains charger cable with the vacum cleanerr at the weekend, so i ordered i new one from Ebay. Rather stupidly (as an "official" one would only be £1 more), i bought this unbranded one:

UK MAINS CHARGER FOR SAMSUNG i5700 i9000 GALAXY S on eBay (end time 02-Apr-11 14:51:41 BST)

When it arrived i noticed that the output is different: 5.5v 500ma as opposed to 5v 700ma from the one that came with the phone.

I know tha ampage will affect charging speed, but am concerned about the extra 0.5 voltage. Is this safe to use?
[Galaxy S I9000 Accessories] Holmes108:
I'm curious about this too... I thought the "U" in USB meant Universal.

I just ordered 2 micro USB chargers from Ebay for my GF's Sony Vivaz Pro and my Captivate... neither work.

Her's doesn't recognize the charger at all... mine beeps and says "charging", but the battery level never goes up.

My chargers are 5v 500mA.

The chargers were listed as Blackberry chargers, but had a long list of compatible phones underneath (none matched our phones, to be fair.)

Now I'm afraid to buy any more generic chargers....
[Galaxy S I9000 Accessories] paddyb:
I don't know if the output voltage is part of the USB standard or not. I know that computers output 5v and it seems like a lot of phone chargers also do. However, i've seen some external battery chargers listed as compatible with the SGS listed as 5.2v, so maybe theres an accepted voltage range? Does anyone know for sure if a 5.5v is acceptable?

I'm not sure why the ones you have don't work as the specs seem right,possibly they are faulty?
[Galaxy S I9000 Accessories] Holmes108:
Yeah, I'm not sure. I certainly thought so, even though it seemed pretty "unlucky" they both might be faulty.

I did ask the seller, and they claim they are NOT compatible with my phones, but I just don't get it. They're offering me a refund, but at $4 each it's hardly worth my time mailing them.

I found some forums online of a small handful of people like me with chargers that won't work. It seems people with this issue were using 500mA chargers, and anyone using a 700 or 1000 had no problems. This wasn't necessarily because all phones either require 500 or 1000.... Someone also said it's only very certain phones that are built this way. That they require newer, or more powerful chargers... but that it's not the case with all new phones/smartphones.

But there were others who said 500 should charge it, just more slowly.

I still think Micro usb is Micro usb, period. That's why the EU (and here) have been looking at making these chargers universal. I think I'll just try my luck again with another charger.
[Galaxy S I9000 Accessories] paddyb:
You could try this one, which claims to be (and looks like), an official SGS charger:

http://cgi.ebay.co.uk/Samsung-i9000...ories_MobilePhoneChargers&hash=item2c5b2d355a
[Galaxy S I9000 Accessories] ro_explorer:
5.5V is supported. I've tested a very wide range of chargers for my SGS and all worked.

The voltage range of these chargers is 4.8V - 5.6V and all worked just fine.
[Galaxy S I9000 Accessories] Daum Ex:
I've actually got an original Nokia USB charger which is declared at 5.0v/550mA and it works like a charm...

Model is AC-6E:
[Galaxy S I9000 Accessories] paddyb:
Well finally decided to give the ebay charger a go. Plugged it in, a green light lit up and plugged the phone in. The phone didn't recognise the charger, no indication the the notification bar that the battery was charging. Unplugged it and and tried again, and now the light on the charger doesn't even come on! Won't be using it again.
[Galaxy S I9000 Accessories] Lukeenho:
Another question on the topic : Is it save to use charger with higher Amperage ?

I mean original samsung one is 0.7A, could something go wrong if I´ll use 1.0A charger? Thanks

EDIT : Answer no needed anymore - found it in another topic. It should be safe
[Galaxy S I9000 Accessories] redpilleatr:
I believe any microUSB charger will be safe. Ideally, you want the highest voltage and highest current possible.

I've heard that the phone will use the data lines to tell the USB charger what voltage to set. This ensures voltage compatibility. Then the phone itself regulates the current.. it will only draw as many amps as it needs. So if the PSU can handle 2A, your device may only draw 0.725a for example, but it's safe. You want a high current one to ensure the phone has all it can take.

BTW, I'm not an EE person, so double check what I said.
[Galaxy S I9000 Accessories] cdmackay:
I fear it's not that simple, especially with dumb chargers that can't negotiate current using the USB protocol, and instead may short the data lines, in various ways, instead to tell the device what current to draw...
[Galaxy S I9000 Accessories] cdmackay:
There's an explanation here of why different chargers do indeed make a difference:

http://en.wikipedia.org/wiki/Usb#Power

see in particular the note on the Battery Charger Spec.

In particular. my own testing shows I can go from 500ma to 700mA charging current simply by changing a small connector in line between the 7Ahr battery I'm using to charge the phone, and the phone. That's due to the nature of the short on the data pins.

There are proprietary tweaks to this mechanism; e.g. iPhones use voltage signalling between the two data lines and ground to indicate various things to the device.

All of this is only for "hosts", i.e. chargers etc, that don't implement the USB protocol and so can't engage in the normal current negotation that occurs when connecting e.g. the device to a PC.
[Galaxy S I9000 Accessories] projeto56:
Would i **** it up pluging a 5.8 volts solar charger on my phone?
[Galaxy S I9000 Accessories] HdX75:
It's a bit too high.

You have to know that slow charge = long battery life and fast charge = more battery drain after a couple of years maybe months ;)
[Galaxy S I9000 Accessories] Pezmet:
So usb charging is better then wall charging with original charger? because i noticed that my phone hold it`s charge better if i use the wall charger.
[Galaxy S I9000 Accessories] HdX75:
Maybe because the current is higher. My battery voltage is arround 4200mV at 100% and 4100mV with USB

For the solar charger 5.8 is really high but the wall charger is ok
[Galaxy S I9000 Accessories] shifu.2806:
guys can anyone tell me what would be the reason that my Samsung j7 prime charger is giving me 4.63v instead of 5v .. the rating is 5v on the charger. is that possible the ic or some other thing is damaged? in that case what would be solution?
[Windows Phone 7 General] nrfitchett4:
Nothing unstable about my hd7. Wonder if LG ha finally broken the feature phone stigma.
[Windows Phone 7 General] jlott069:
@nrfitchett4

I have to say I think so with this one, i always hated LG, but i fell in love with the physical keyboard, even before NoDo i didnt have marketplace issues... out of the three from AT&T, this one is def my fave, and it seems like it is just so much easier to hack and change with MFG... with your HD7, does it have anything like MFG already on the phone? My understanding was HTC phones had to use software on ur PC to get inside
[Xperia Arc General] rainerateimer:
Is the screenprotector that came pre - installed with the Arc removable? It locks like it but i dont wana try to peel it of unless its necessary.

Has anyone tried tto remove it?

How does the screen feel without it?

Thx Rene
[Xperia Arc General] im_iceman:
It is removable.. same as on x10.. but I wouldn't if I was you!.. the screen will feel slightly better but the benefit of having it far outweighs the benefit of removing IMHO.
[Xperia Arc General] rainerateimer:
Thanks for the quick reply :-)

Thats good to hear, because what sense would a screen protector make if it wasn't removable in case it gets scratched.

Ok Ill leave it on as long as possible - the screen is more than responsible enough and feels great already.

Thx
[Xperia Arc General] im_iceman:
It's a better protector than you'll ever get anywhere else - thicker and more robust.. protects the mineral glass from bumps and such too.. and it's applied in a controlled environment so you get a perfect finish.. which you're not likely to get with a home application!
[Xperia Arc General] StickyGeko:
screen protector always!!! but isnt the screen ment to be gorilla glass too? so should matter that much if someone removed it(dont know why they would tho)
[Xperia Arc General] rainerateimer:
Its just that in case I get a nasty scratche on my screen(-protector) I want to be able to replace the scratched foil with a new one. And the pre-installed one just seemed like its ,, unremovable" to me. But now that I know its removable - why aren't all manufacturers installing those? It just seems like an obvious thing couse I think most users install a protector after buying a new phone anyway.
[Xperia Arc General] ronniecross:
One of the better reasons to go with Sony Ericsson? ;)
[Xperia Arc General] trishul:
so that means my brand new ARC came with a pre installed screen protector so i dont need to install another one which came in the box over it ?? or am i supposed to remove the pre installed one and then install the new one after the original one gets scratched !!! ???
[Xperia Arc General] im_iceman:
It's just a spare.. you don't need to remove the preinstalled one.. in fact I'd try to wait as long as possible before removing, cos you'll never get one installed as good as the factory fitted one!
[Windows Phone 7 Development and Hacking] UzEE:
Was just going through the code of the latest WP Support Tool by Microsoft when I noticed that there are two different models of Samsung Focus.

Samsung Focus SGH-i917 MMCP

Samsung Focus SGH-i917 SMCP

Both these versions have seperate FFUs as well. Anyone has any idea what's different between them?

As for Omnia 7, it only has one model so I don't think its carrier specific.

Update:

Here's a screenshot
[Windows Phone 7 Development and Hacking] VonCrisp:
This is a long shot....

Maybe it has to do with the fact that Omnia 7 is just NAND whilst the Focus can entail expandable storage.

Just a rough guess.
[Windows Phone 7 Development and Hacking] UzEE:
But that shouldn't mean it has two different models. If anything, there are two models of Omnia 7 - 8 GB and 16 GB - so it should be the device which lists two models.
[Windows Phone 7 Development and Hacking] Vintage144:
it has something to do with the memory of the focus

mmcp=MultiMedia Plus Card (MMC Plus) High Speed Memory

SMCP-Smart Media Flash Card Memory (im not sure if this is correct)
[Defy Android Development] bokeron2020:
Hi.

I'm a total newbie with a problem.

My Defy has a bug, I believe. When the phone should be on suspend mode, a process called "suspend" starts using a lor of CPU time, so the battery lasts for just a few hours.

This is, I suppose, not the forum for asking for help about this, so I'll just say I've tried everything I could think of... and now I would like to use "strace" to... trace what's going on.

There are two problems.

One, the bug dissapears when the phone is suspended but connected to USB... so issuing commands is a problem without connection :) ... I suppose I could try WiFi, but I haven't tried yet.

Two. What I call the "suspend" process seems to be a kernel thread... so, I can't use strace.

Could someone, please, explain me wich command (if any) can help me trace the activity of this kernel thread ? Or... well, any other way you can think of.
[Defy Android Development] chaihg:
Good question and interesting one. Will wait for others to answer.
[Defy Android Development] Beach_Head:
You have strace compiled for Android?

Try issuing the command via ConnectBot or any other free terminal so you don't need to be connected via USB...
[Defy Android Development] bokeron2020:
That's part of the problem... I'm "hunting" a bug that only appears when the phone is suspended... If I use ConnectBot to write commands... the phone is, by definition, active. So...

Also... we have another problem: strace fails because "suspend" is not a process but a kernel thread... or that's what I've been told :)
[Defy Android Development] bokeron2020:
OK... I've finally been able to set up adb over wireless.

But strace doesn't work, and "top" shows that suspend almost always uses around 5%.

But... I still can't trace what suspend is doing.
[Defy Android Development] bokeron2020:
Would someone help me if I beg you on my knees ? :confused:
[Defy Android Development] fritolays:
Use the dalvik debugger, open command window and type ddms (assuming you have android sdk).

Once open under the Device menu you can see running process's/track them.

Heh didnt see that it doesnt happen when connected to usb. Dont know if ddms works over wifi too, should, but give it a shot.
[Defy Android Development] Beach_Head:
Why not just re-flash a stock SBF to get rid of the problem?
[Defy Android Development] bokeron2020:
Because, if it were that easy, the problem would have gone away sometime while flashing a sbf for the first 5 times...

Nope. It's either a bug or a hardware failure, I believe.
[Defy Android Development] martinml:
You can't track kernel threads via ddms. Only userland processes.
[Defy Android Development] adlx.xda:
All adlxmod roms, starting from my first Cliq rom have strace ;)
[Defy Android Development] bokeron2020:
Can you trace the "suspend" kernel thread ?
[Defy Android Development] bokeron2020:
That was an easy question, wasn't it?
[Defy Android Development] martinml:
http://user-mode-linux.sourceforge.net/old/debugging.html

You can't because "(...) the kernel's threads are already being ptraced for system call interception, so gdb can't ptrace them"

Also, you could use KGDB, but it requires compiling your own kernel and a special setup, which is not possible in the Defy.

[HD2 General] T-Macgnolia:
Are you using a NAND Android ROM or a SD card build? The reason I ask is most NAND Android ROMs work good with the 2.15.50.14 radio, and I have only read reports of the robot voice issue in threads for SD builds. Also if you are using a SD card build and you are still runningvWindows Mobile, ifthe Win Mo ROM is not a 3.14 or a 3.14 based ROM the radio will cause some issues with your HD2 such as frezes and such.

Edit: I looked back at your first post and I think you are running a NAND Android ROM so just disregard some of what I said. But I do recommended changing your ROM I use Hyperdriod check my sig for a link to it.

Hi, I simply luv my Defy for everything except the camera... How is it 5mp same as iphone4 but the quality differs so much? Or is there a tweak to e processing available which I dun know??

Many thanks... :)
[Defy General] vick33:
Why do you think it is much worse than the iphone 4's camera? It makes pictures a littlebit darker but in good light i think it makes better pictures, because the iphone blows the whites out, and oversaturates the picture. But neither the iphone nor the defy is any way compareable to even the cheapest point and shoot camera
[Defy General] Ph1b:
The new firmware 2.2 is improving the camera quality. Just wait a few more weeks for the release.
[Defy General] Whitedefy:
I agree the defy camera is better than an iphone4 in verygood lighting... But think all other manufacturers sld seriously learn from apple tat when we use our camera on our phone... We simply want fast & quality nice enough to share... Everyday living conditions n impromptu moments n for me I like to take food pictures... most of the time its difficult to have good lighting... For iphone4 its like 90% of such pics will turnout excellent... Whereas on my defy I have to find repeatedly for a good angle n light for a good shot...

Moto Defy has 2 different image sensor:

1. Omnivision OV5642 (sensor with green lens) - small file size, big compression, huge antibanding and denoise, blurry image, image compression done by ov5462, image quality, compression is controlled by system/etc/mot_ise_imager_cfg.bin

List of registers used by this sensor are in datasheet:

OV5642_CSP_DS_1.11_OVT（5M EDoF AFC）.pdf

OV5642_CSP_DS_1.11_OVT.pdf

search in google: OV5642_CSP_DS_1.11_OVT.pdf wenku baido

Changing hex values (registers ov5642) in mot_ise_imager_cfg.bin we could change image quality, reduce jpg compressions, disable antibanding and denoise (image should be less blurry)...

2. xxxxx - like in milestone 2?? - (sensor with red lens) - big file size, some color noise, sharp image (2 of 3 checked phone with BT33 has this sensor)

Sample image with green, red lenses in attachments

if you have defy with red lens (image sensor like in milestone2???) you should get photos like point 2 (files in archive: defy_red_lenses.jpg, defy_red_lenses_2.jpg), 2 of 3 checked phone with BT33 has this sensor.

franek123

please answer me
[Defy General] geejay2:
Green sensor is OV5642 is probably same as IPhone 4 sensor. Red is like Milestone sensor. So green should be theoretically very good.

Problem being Motorola hasnt figured out how to use the OV5642 with the TI OMAP processor.

Clearly, without 720p Motorola is giving away the chance to position the Defy as high-end phone in the market. If they activate 720p they can keep the price up for another year.

Or they invent a Defy HD with better screen and 720p and increase price as HTC did.

Anyway the 848x480 patch with lgCamera makes me already reasonably happy.

Hi gang, i have a few questions regarding factory reset

(settings --> about --> reset)

If i reset after updating NoDo, would i still be in NoDo after the reset?

If i unlocked my phone (with NoDo update), would i still be unlocked after reset?

What exactly does reset do to the OS besides removing media, apps, settings?

Thank you all very much for responding!
[Windows Phone 7 Development and Hacking] Freddy2Fred:
It formats the phone and it returns into its original settings. In other words, it starts all over again. You still will have the NoDo update. Now a far as unlocking, you might not able to unlock unless you restore the pre-nodo version saved on the Zune software. I formatted my hard drive s my backup is gone. I'm stuck with the NoDo now with a locked phone. Can't do anything lol.
[Windows Phone 7 Development and Hacking] Heathcliff74:
Freddy is right. NoDo update, together with base-settings is stored in a part of the firmware. User settings and files are in another partition of the phone. During the update the OS partition is backed up and the user partition is backed up. The OS partition is updated and the user partition is left as it is. If you hard-reset, the user-partition, including the unlock-settings is wiped. Leaving you with NoDo and no unlock.
[Windows Phone 7 Development and Hacking] toothfish:
so now the only solution is to wait for a NoDo unlock then...if u want to reset and still be unlocked

wonder how long it will take~~
[Windows Phone 7 Development and Hacking] TheOnly1:
You always have a workaround. If you need to do a factory reset with NoDo already on then do it. Afterwards flash a 7004 ROM for your device, unlock, reupdate to NoDo :) It's a bit more work but worth at the end of the day...
