Hey guys,
A few questions about my Galaxy S2 running Android 2.3.5. I've read a lot of the stickies on this forum and on others but still have a few questions:
1) Why does my Galaxy S2 charge so slow via my car charger and wall chargers? My iPhone charged 100x faster... Is Micro USB not able to charge as fast as the iPhone connector?
2) If my phone is locked and I press a button, the screen remains fully lit for 20+ seconds. Is there a way to change this to about 5 seconds? But when the phone is unlocked and I'm using it I don't want it to ever dim and I don't want it to ever lock automatically.. Is this possible? I couldn't find either of these in the settings??
3) Is there any way to speed up my device at all? It lags slightly when I unlocked it and want to open an app.. I've put my music and photos on my 32GB card so it's only really the OS and apps on the actual phone's hard drive. The non-standard apps that I have installed are:
- Asphalt 6
- Facebook
- Defender
- Shazam
- Swiftkey X
- eBay
- Adobe Reader
- Fancy Widgets
- WidgetLocker
- JuiceDefender Ultimate
- Zedge
- Flashlight
- Paper Camera
Are any of these known to slow down the device? Any tips (besides the obvious ones) for speeding up the device?
4) I found a link (spreadsheets.google.com/spreadsheet/pub?hl=en_US&hl=en_US&key=0AnO2-4y6yE1gdDJRekl4QmkyNmIzUmRvX2h3UDVkQXc&output=html) which shows what's safe to remove... But how exactly do I go about removing them so that everything is removed and irrelevant files aren't left behind?
5) I haven't rooted the device yet... Should I? There's not much more I want to do to my phone besides make it quicker if possible, as it already does everything I want and more!
6) How can I backup my whole device as an image (I'm almost starting to miss the fact that iTunes backed up my iPhone and it was so easy to restore everything...)?
Cheers!
1) usb charging only provides 450mA and ac charging provides 650mA, iphone charges at a full 1amp
2) there should be a screen timeout setting in the display settings
3) it shouldn't lag, perhaps try some newer firmware
4) titanium backup, but you need root first
5) see #4
6) flash a cf-root kernel for your firmware with cwm recovery, there's an option in cwm to backup/restore the whole rom

Exactly the same answer from me .
jje
1) so even if I get a charger which is supposed to charge faster than that, the Galaxy S2 only accepts that much power?
2) thanks
3) I'm on the newest firmware already... Will deleting all unused apps help speed up the device much?
What's the easiest/safest way to root the device?
Cheers
EDIT: Another question.. Am I better to keep my photos and music on my phone or memory card (Samsung 32GB micro SDHC)?
Heya... To answer some of your questions:
1) while there may be chargers that allow more or less amps, the maximum current that your phone actually takes is given by a value inside the kernel. So you need a kernel that supports this feature, however it's generally adviced to stay away from overjuicing the charging, you can fry your device.
3) Android manages running programs by itself. Some are harmless to stay inside the resident memory while some can prevent your device from getting a deep sleep state. My advice is to use Titanium Backup Pro to freeze/uninstall unwanted apps.
I did my first root with hellcat's kernel. Be sure to know what you are doing in ODIN and read the tutorial thoroughly!!

EDit: yes storing media files on external sd is a good odea!
I have only sync'd with this PC
I have not installed anywhere near 5GB worth of apps
I have 0MB media on the phone
I have moved the reserved space slider to 0%
Zune tells me 5GB Reserved Space, only 770MB Free
I've only had the phone a few days and there is no way I have filled 5GB with anything
How can I make Zune stop being a PITA?
I have even edited the PC registry to enable USB Storage and there is only 18MB used in all the files in there yet it still tells me only 770MB free
I do not want to reset the phone and have to set it back up again
EDIT - Removed about 3 xbox live demo games and recovered about 1.5GB Space, damn those games are big, still missing about 1GB if I say 1GB is for the OS and 1GB is for GPS maps and other bits and bobs though
Have you checked the free space on the Phone? Did you ever connect your phone to another PC? Have you installed Navigation Software with large maps or games with high graphics? Did you try to hard reset your phone (this should give you your space back)?

I've recovered some of it, but still seems to be a lot of reserved for just a couple apps, GPS maps and the OS
3.38GB Reserved now but is still too high imo
Not sure if it is wrong, just would like to get some explanation of this. Phone has bit less than 1GB ram available for apps and default behavior of Androuid should be to use it all for caching recently run proceses, because there is no difference if memory is free or taken - it uses same power.
I have Viper ROM 1.06 and using Nik3r kernel, tested with and without dataswap mod (128MB). Even tried to tweak Viper settings for minfree setting, using Multitasking ultimate profile. And still the same behavior. When I check available memory, it always sits around 750 used out of 980MB. Regardless what and how many apps I run.
Problem is, that when phone is not used for some time I see almost every time apps starting instead of fast switching from memory. Its mainly visible for me on FBReader, which I use to read ebooks every time I have little spare time. I pull phone from pocket, start FBReader and voila, it is starting from scratch loading book. Its 2-3s, but still. its relatively small app, shouldnt be killed most of the time thanks to system policies on free ram.
When I try to play with phone and run as many apps (start FBReader, home and run Chrome+load 2 tabs, run Camera, run Viber, run Tapatalk and back to FBReader) to force it to close my FBreader from memory, everything works fine and it swaps back in immediately. Even though checking Apps tab in settings shows memory usage about 750-800/980, not fully stuffed with cached apps (think its not showing correct numbers? Or not showing memory taken by apps in empty state?). But anyway. I give up, turn off my phone and let it be for some time. Then I check for example for SMS and would like to continue reading my book. And FBReader is loading as if it was closed. Why?
Seems to me like phone does cleaning of cached stuff in memory after some time when it is not used? Cant say precise when it happens, it just annoys me to see that system shows all the time around 750/980MB used and still is unable to keep my app in memory for longer period when it works fine if I test it directly.
Any ideas/tips/explanation?
Hi, I have the same issue with the fb messenger (chat heads)
I
Android still shut down and it doesn't restart...
Any idea ?

How do I free up RAM for my Samsung Note II LTE GT-N7105 on stock Android 4.3, rooted?
I am an Android retarded user looking for a patient teacher who will walk me through the Android RAM mysteries and answer a few question and, in exchnage, I can teach about the secret world of Traditional Neapolitan coffee infusion: home roasting, grinding, preparation and... savouring or, alternatively, Home Theatre! Your pick!
Smiles!
On average, at startup,
- Clean Master shows:
> 50% RAM
> 70% Device Storage
> 20% SDcard External Storage.
- Titanium Back shows:
> 500MB free RAM (of 2.11GB)
> 4GB free Internal+Media (of 10.9GB)
> 50GB free ExtSDcard (of 63.8GB)
Starting with these numbers, the device freezes after a bit of usage of the Swipe (Nuance) App. But I recently played with a 78 year old banker's GT-N7105, which was 20 times faster than mine, while running the same Swipe keyboard App: "My nephew geeks around a forum called xda-developers!"
1. In general, what's the relationship between installed Apps and RAM usage? Sometimes when I kill an app it frees up a bit of RAM, sometimes a lot and sometimes nothing at all.
2. Do installed (but not opened) Apps take up RAM space just by sitting in my Apps drawer? Should I uninstall all the Apps which I downloaded because "one day I might need it" and never used them or are they harmless (RAM wise) if I don't open them?
3. Do Apps which have been launched and now sit in the background take up RAM (as in Windows)?
4. Is there any difference between "fereezing" and "un-installing" an app as far as device operation speed is concerned?
5. Do I need to make sure that Apps don't start up if I don't need them (Google Play Services, Google Play Store, Goggle Translation, YouTube, Video Player, S Voice, Picasa Uploader, Nearby Service, Nearby Devices, SNS)?
6. If they eat up RAM, how do I make sure that they don't self start? Android Assistant App?
7. If background open Apps eat up RAM, is there a way to kill them automatically once I open a new one without loosing the cahced data which i might be using?
Thanks in advance for your time and expertise.

Ugggg I hate this app lately! Just spent ten minuets answering all your points fully and it gave me stupid permission error! Even wrote a nice analogy about ram and libraries...forgive me if I'm brief now
Sum it up
Poorly made apps or ones that need to stay in the background to operate fully or spy on you stay in ram, many don't, dump bad and seldom used apps, stay away from task killers, if you need one use watchdog, see what's actually using cpu, better battery stats or cpu spy can help too. Freezing is fine, v6supercharger can help you, setting background process limit in developer settings can help
You have a nice snappy phone, get rid of junk and use nice roms and you'll have no issues

i would suggest installing and using greenify, since u already rooted.
post #3 of that thread is worth reading, probably will answer most, if not all of your question regarding android ram usage
@an0nym0us_
Cool advice, thanks! I installed and I will try it now.

@demkantor
I only got the jist of it but I didn't really understand... any chance to try again, when you have more time on your hands?
There are 3 aspects that make up coffee flavour: the beans' quality, roasting and preparation.
Beans (origin, ripeness, homogeneity, dryness) and roasting (tempreature, duration) are, for now, out of your reach. But preparation isn't.
Most infusion's preparation depends on 3 basic parameters:
- temperature
- time
- contact surface.
Threfore brewing time and temperature and the beans' grind size (and also the grinding method) will influence the coffee taste: the greater the time, temperature (up to 95°C) and surface the greater the organoleptic proprieties' transfer will occurr. Which does not necessarily mean the better taste... more on that in the next lesson.
Organoleptic properties are the aspects of food or other substances as experienced by the senses, including taste, sight, smell, and touch, in cases where dryness, moisture, and stale-fresh factors are to be considered.
The desire x is my business mobile, so i dont want to mess with it in case any problems and i get charged for the phone. to be honest i struggle, its terrible device compared to my personal phone.
I need maps to navigate around, the connection in London drops when im close to destination, i blame this on the tall buildings blocking signal but not sure if 100% the reason. i was told may help to download a map program and use this way, but there is no storage free, and i have only 2 small apps required for work.
Is there a way to delete apps like chrome and facebook / twitter which came pre-installed but i cant remove them.
I tried adding a sd card but it wont allow me to move apsp to sd card. ( so failing the deletion of apps, can i roll back the rom to a older version?
pretty weird that the data partition is full, when there are only 2 apps installed.
are you storing all your company-mail on your phone or something like that??
whatever, as first step you can try to locate the storage-hog by using a storage analyser like https://play.google.com/store/apps/details?id=com.mobile_infographics_tools.mydrive&hl=de
i have downlaoded the program but not sure what i am lookign for?
can i remove the android APK files? surely once program isntalled i no longer need these?
A takes 591mb
O takes 127mb
App storage is taking 2.51Gb of 2.91 available.
Apps = 704Mb
other = 1.82Mb
Available - 408Mb but when i download the map program it requires me to download a large file for offline maps. plus i have this space as i deleted a few photos which were for work but old. so when i take photos this space decreases further.
the only apps i can uninstall are the two apps (about 40Mb each for work, plus i have pocket locker and now this analyser which have small footprints).
