I was searching online to see how to make a shortcut to toggle the 3G connection on and off without having to sift through multiple menus. I came across the method of having a long press on the power lock button to pull up the menu but mine does not show the network data on/off option and never has. It only shows
* Silent mode
* Airplane mode
* Power off
* Restart
Nothing else. Is there a way I can make a shortcut or some other way to ADD the network data on/off on this pull up menu from the power lock button? By the way why would my phone not have this option from the start when the phone came with Gingerbread and was updated to ICS 4.0.4? I have Sprint so they call this the Epic 4G Touch, so not sure if it was Sprint that buggered this from the other SGS2s that have this feature or not.

I have a black background, I keep the display settings at the lowest brightness settings, and I keep the screen off when I'm not using it, but my phone is dying after 8-10 hours if I don't use it very much and 4-5 hours if I use it regularly. Every time it indicates that it needs to be recharged, 65-80% of the power is going to the display. I...don't see how that can be.I'm using a Samsung Vibrant that I bought on July 30th.

I live in the middle east and i bought a galaxy tab p7500 3g 64gb from Amazon..as you know they come without arabic language so i need to flash the arabic firmware (ROM) and i already have all the files ready for flashing..but my question is where can i find a pit file that is compatible with the 64gb unit..because from my experience flashing the wrong pit file it will reparation the sdcard incorrectly.
i.e. once i used a 16gb pit file on my 32gb galaxy s2 my internal storge changed from 32gb to16gb and the problem didn't get solved untill.i flashed 32gb pit file into the odin..One last thing if i installed the arabic rom without using the pit file and removed the tick from repartion in odin will this method work.

I've had a Droid X2 for almost 2 years, and as phones usually do, the battery life became pretty bad. It would get to 5% and then quickly die halfway through the day.
I purchased a new battery, and found it to be just as bad (supposedly). It would be down to 5% by noon without much usage, so I thought maybe the problem was with my phone and not an old battery. I'd just turn it off or try to find a charger...
It took me a few days to realize that it lasts hours past when it gets to 5%. HOURS. It reached 5% at about 1pm EST today, I used it my whole commute home on the train, made a two 5-10 minute phone calls this evening, and now past 9pm it still hasn't died.
So, it's not the battery. It's not the worst problem to have... but it would be really nice to know how much battery I have left.
Note: I rooted my phone about 1 week before I got the new battery.

This question seems a little (a lot) odd. because naturally we want our battery to get fully charged to get the most stamina out of it.
but i read a while ago that for Li-Io batteries the most efficient charge range are 10%-90% so basically that means the full charge -discharge cycles aren't good for the battery but harmful as it cause them to die faster..
anyway i considered this reading as a good theory until i bought a sony vaio laptop which had a battery preservation feature (it limits the maximal charge to 80% or 50% depending on the option) and for more that a year and a half my battery still performed well (less than 4% degradation) so i thought this was a real deal after all.
still the use cases for a laptop and smartphone are vastly different (the laptop can sit with 50% charge just fine since it will be on charge most of the time while the smartphone has to get the maximum amount of energy to last without a charger)
so is there (or can it be made) an app that can limit the charge (to 80% or 90%)

I checked my phone battery from the sys folder and its showing only 500 charge full design and i think i am i having a battery indicator problem bcoz of this as my phone drops the charge from 100 to 1 % in only 1 to 2 hours of use and stays on 1% for many hours.So is there any way to change it with actual atrix battery capacity. I am facing this problem from the first day with original atrix battery that came with the phone i also tried various calibration methods,roms and kernels but nothing worked.
/sys/devices/platform/cpap_battery/power_supply/battery
My phone uevent is showing this
Powersupply-capacity=5
Powersupply-voltage-now=3836000
Powersupply-temp=260
Powersupply-charge-full-design=500
Powersupply-charge-counter=1

I purchased an extended battery, a Motorola branded BP7X for a Droid 2 phone. It's rated at 3.7 volts/1820 mAh. I tested it with a volt-ohm meter and got a reading of 4.2 volts.
When I install the battery in the phone and connect the charger (phone is off), the charging graphic shows the battery is fully charged. I can power on the phone with the charger attached, but as soon as the charger is disconnected, the phone dies. I tried this battery in two Droid 2 phones and got the same behaviour. Is this an indication the battery is defective, or is there something I need to do to make the battery work?

I have been having a major problem with my Samsung Galaxy S3 phone. The internal memory of the phone should be 11.25GB (even though it should be 16, but I know how these stuff actually work), Surly I have an extra external SD card, but that's not the problem. The internal memory keeps being filled with nothing.here is a picture to demonstrate the situation:
As you can see the total space is 11.25 GB and if you count the applications, pictures, videos and miscellaneous files, they constitute no more than 2GB, which means that there should be no less than 9 GB left as available in the phone's internal memory, but as you can see I have got 5.84 GB available. How did that happen?
I have rebooted the system yesterday when the internal memory was completely full (even though I have only 2GB filled). And I have a feeling that by tomorrow I will get the memory completely full without downloading or adding anything on the phone.
And don't tell me I should clean cache or whatever that thing is, because I have already done that, and it's not working.

When the android device is powered off (shut down completely) and plugged in you can hit the power button briefly. This shows a battery with a certain part shaded in to presumably indicate how charged it is and I suppose if its charging or not. There are some dots below the battery. What do they show? There are 5 dots that progress from left to right (empty are area to full area), does this indicated that the battery is charging? Does the rate of progression indicate how fast its charging? Do the dots do something else if the battery is discharging? Is there are lighting bolt inside the battery if its charging?
I have searched and searched and never seen an explanation of this powered off screen, which are slightly different depending on devices (some have charge indicator (i.e., "90% charged") and some just have the dots, some have lightning bolt inside battery some do not).

Android 4.0.4 on a Motorola Electrify II (phone is about 2 months old).
Set the Battery Full Notification - it worked well for awhile, then simply stopped. (???)
Text message notification still works fine, but not Battery Full. I have tried resetting, and volumes are turned up for everything including notifications.
The local store suggested that I look online for an answer (hence this post), they said the phone settings looked fine. If a fix isn't found online they will restore the phone to factory settings to see if that works.

I searched all over and cannot find something about this issue: My problem is all my photos in gallery look really low resolution until I zoom in slightly on the photo. At that point the detail snaps in. But when I just open it up it looks to be about half res. Any idea what is causing this and how to prevent it?

So i broke the screen on my Galaxy Nexus.
I also broke the power button (flex ribbon) at the same time.
I am told that the technicians will wipe the hard drive when they go to fix the screen.
I am wondering if there is a way i can backup the pictures from my phone to my PC without the power on the phone turning on.
Also, is this wipe is even necessary, i have another tech who seems somewhat shady and small scale but claims he can fix it without the wipe.

I have this strange memory problem on my Samsung Galaxy SII Last week I flashed CheckRom RevoHD on my cellphone and everything went well (Titanium Backup etc...)
This morning I downloaded and installed Omega Files (Omega Series ROM kitchen) on my cellphone after a few hours it switched off. And then it took like 10 minutes to switch back on as the screen was stuck on the splash screen.
I had like 500-600Mo of free memory out of 2Go for apps and now I only have 20Mo...
Is there any file manager (that sorts folders by size) out there so I can do so cleaning ?

I just installed a custom bootanimation.zip on my phone and it looked like all was well for a moment until the screen went blank 1/3 or so through the animation. The beginning worked properly and the animation began to play, my old startup sound then play(I never changed that) but then the screen went black several seconds after the start sound played.

How to disable the baked-in power saver feature in some Samsung Android phones? the one that dims the screen, turns off the keyboard backlight, and doesn't let you use the camera once you hit 15%(or 10%) battery left? can't stand that, for my own needs anyway!
i figure it might be an edit to the kernel source code, or something like that. i just don't know where to do that. I know it can be done tho, because i remember having some ROMs on the Epic 4G that had that junk disabled. guess i'll also see if some of those old devs. are still around.

I have the Samsung Galaxy S3 (Japanese version) and in my notification bar, I can see the Power Control Widget. But in my phone there are 9 options (wifi, power saving, data, notification, etc.).
I could see the source code for the "basic" power control widget here (this one has only 5 options).
I'm wondering if the source code for the version I have is available somewhere.

my galaxy s2,it is rooted,and i have another problem : the phone restarts by itself and gets stucked in the boot loop, i never flashed a new rom ,it is running the stock rom,Someday i needed to factory reset the phone so i rebooted into recovery mode (power + home button +vol up) ,. I booted into recovery mode but the power button does NOT react as 'select' button although it works just fine for power on and off. I select a function and press [power] an the first line becomes the selected. pushing it again just flashed the screen. But pressing it long turns the phone off,and even after the factory reset from phone directly(with out going to recovery mode)
