Hi all, is a long time that I was determined to make this guide, which talks a little bit of memory and a backup, but not in the traditional way, there are many guides who speak backup and restore on the forum, this guide aims to clarity on what is davero save and restore on Android, and quite often emerging from years of windows, to many it is not clear the system, which is both simple and ingenious.
In fact few people know that if a system Android is configured correctly, we could bring the system exactly as we had no need for any backup, or rather save only minimal data.
In fact, Android is designed precisely so that in case of hard reset is possible to recover most of our data assolutament without saving anything.
How can you say? A little cloud, and thanks to google, thanks to some extraordinary system that we have at hand.
It is to make an introduction, some phones like the nexus s, the dual optimus, the galaxy's have a partition of internal memory which is viewed a bit like the SD of the other external phones, as a general rule that says of this guide is also valid for them, but keep in mind that the external removable SD, where present (in no nexus) is used only for photo papers and films, while the rest is used for internal storage.
We must first begin to understand WHAT and WHERE you install to get through to understand OCSA we can restore and what may be unnecessary or less important to be clear I AM NOT SAYING THAT I DO NOT GO BACK FACTS, a spare copy of every thing is fine it, but is often used even when not needed and when and how best to act otherwise.
We begin to see what and where you save files on Android:
THE SYSTEM
And 'the directory / system of our phone and also has a dedicated partition in the internal memory that contains all the firmware "base" includes all pre-installed applications, widgets, etc. keyboards.
We can find it in / system / app
\
THE APK
They are the real applications, we download and install an application in the market is. Apk
These are saved in order to function in a precise post system and is usually the directory / data / app on your phone
THE DATA AND THE CACHE OF APK
It 's the hardest thing to understand, an application, and is used when the install saves a certain amount of data that can be variable depending on the application itself (from a few kb to a few megs), many applications do not even have to save data, but others do and are represented by such preferences that we ourselves, as if spuntiamo an option rather than another, or choosing a layout type rather than another if the applicazionelo allows, or if the level of bailouts it is a game, in short everything you need to find an application as we have decided to appear and then leave the options configured to our liking so.
These data are stored by the applications to be found in / data / data is saved for every apk a special folder with the data reported in the application itself.
The caches are special types of files used temporarily or often (usually a few kb), which serve to ensure that the application can draw from in order to make things faster, or temporary files that are dynamically replaced.
We can easily delete data and cache any application, they will be recreated as soon as we open the application itself, of course, the application will restart with the default options, and if it is a play off-line again from the first level and so on.
ADDITIONAL DATA (also called extra cache)
Some applications, especially games or navigation systems require a lot of data to work and would occupy much memory required for this and once opened the same applicazzione to download them from the network and in some cases is asked whether to save them on SD or reminiscent internal, usually because the internal memory is precious, they end up on SD if there is no choice in the application.
These data are usually very full-bodied and are also represented by hundreds of MB and then creates a folder easily recognizable on our external SD card (in the case of phones with internal SD is also used for internal storage SD).
For example, games of GLU create a folder named our Glu SD, and a subfolder with the name of the game and so on.
Other lighter applications such as applications that have widgets that give the possibility to download wallpaper or weather, etc., going to save this data in the default folder Sd / Android / data / nomedell 'application, including maps of maps end up here , and all additional data from applications that do not create specific folders on the SD
Some system folders on the SD are dedicated or created by applications to files that we download on the network, or via bluetooth etc..
For example, the browser downloads its files usually in the / downloads available on the SD filoe we download via tapatalk go tapatalk download folder etc..
It's pretty easy to understand and see if an application has created a folder on our SD (internal phones that have internal storage) and figure out what application it is.
PHOTO AND VIDEO DOCUMENTS
These vendgono all usually stored on external SD (on all phones that have), and then will abbastqnz easy to find a manager with the folder where files are usually saved We take the pictures with the camera is the DCIM folder where classical inside will also find all the photos and video that we made.
The documents that we save where we can save more than we like and we should
CONTACTS AND CALENDAR
We have different sections of an Android phone, at least 3 as we have different agendas and calendars (also install applications via the market)
See you in detail what is best to use and how best to handle this very important aspect
the manufacturer of the phone book
The book google
the rubric of sim
calendar and google calendar
Any calendars or calendar entries installed by the market
we can use them all at once or one by one or only one of them depending on how we organize ourselves, usually the rubrics of the managers are not synchronized on a bilateral basis, but only through software provided by the manager himself, so for the calendar, then a Android phone is very practical and comfortable to use google's address book and calendar to google, it also allows us to merge contacts with our friends on facebook twitter etc..
In any case, when we save a contact address book on gmail, it will immediately be synchronized via internet and then we could do with a PC to organize as best we believe our contact, just go into google contacts with our account and do all the goole changes we want.
We can synchronize a directory with security provided by the program manager, who usually also allows synchronization of photos and documents.
Thanks to the synchronization, we can safely delete contacts of SIM if we are double, so as to make it easier to visulizzazione of contacts and that will not recur in the book as a text message or MMS cinviamo
Even the calendar is the same thing, we can synchronize the calendar with a google account and any other event that we mark will be synchronized on the network.
For photos and documents google video offers everything there is to offer as our movies youtube, picasa for photos and
documents for documents.
WHAT HAPPENS IF IT IS A HARD RESET OR IF YOU CHANGE ROM
Sometimes we have to do a hard reset, or simply want to change ROM, when we do this we delete EVERYTHING THAT'S 'ON THE PHONE.
In the case of hard reset will erase all data downloaded applications and cache LESS DATA ON SD that is not touched and is not necessary to do so (in the folder Android patre secure).
When cambaimo ROM is also overwritten the system.
WHAT 'WHAT AND NO NEED TO RESTORE
We finally got to the point, but without these explanations is impossible to understand what really, it's time to save, restore, when and how.
So we come to the point.
all we have synchronized the phone with google we find in our account as soon forgive and sincronizziamo google account
So our contacts are safe and reappear as soon forgive our google account.
So even if we happen synchronized photos or documents, our photos are on picasa web albums and we can see them on goole + documents of our documents and just put the application or any application that we use to synchronize documents.
The apk should almost always always put them back from the shop, just have AppBrain to get a list of applications that you had.
E 'be noted that on some phones, notably HTC phones and those with CyanogenMod also held official record of applications that we had on the phone, so if you own a HTC, when we finish the wizard and put the google account PROCEDURE TO TOUR the market automatically restores all applications that we had.
This only works if you configure automatic rièristino phones and our account teamite start the wizard, is the sense of HTC, both on cm7 Rom.
If you do not have an HTC phone call or not cm7 may be easier to track the applications you were using AppBrain is using the web market puts everything back in 5 minutes.
If you do not format the SD it has all the data we had previously, and then also our photos of the documents and additional applications, if you must format it just a copy paste to put everything easily.
WHAT REALLY NEED TO RESTORE WITH BACKUP?
Contacts: no use because they are synchronized by many
Photos and video documents: safe on the SD but you can also synchronize them with special programs or directly with google
The APK: all are small and wireless, with the web market is fast putting them back
Additional data: they are safely stored on SD and on some phones are restored by themselves (HTC, Cm7)
Application data: for maggtior part not because it is unimportant configurations, the limit if you play a game off line as angry birds to not lose any past levels
Email: do not serve because they are safe on our account
MMS or SMS: If yes but only if they are important, and if you still saved on the sim are safe, however if you want you can use tiuanium
As you can see Android is structured so that even if we lose everything, a huge part of what is lost can be recovered facilemte and therefore no need to do regular backups or restore colossal, just restore the minimum for the system EXACTLY as before.
Android gives each type of data a precise place to stay in your system if you just want to save only the data of insertions apply only to save the corresponding folder that is located in / data / data and overwrite it with root permissions or replace it.
The same is true for all other things.
Playing a lot with my Nexus 6, I came to want to try Chrome out a bit, for a change from Firefox. And I stumbled on what I consider a very big problem.
All my browsers, I set up to clear history, cache, cookies, etc, as soon as I stop using them. Be it for pr0n, bank managing, or mere general hygiene, I just want the browser to start fresh every time I launch it (I only keep bookmarks and some selected passwords).
Now, with Chrome, there doesn't seem to be any real way to wipe all the crap when exiting the browser. So I started playing with deleting of history, recent tabs and cookie files in /data/data/com.android.chrome/app_chrome, triggered by recent app swipe out (process stop) detection in Tasker. And it worked, for some time.
Problem, after having swiped Chrome out, deleted history files, and checked the history and recent tabs indeed seemed wiped, when tapping on the clock history icon, on the lower right part of the empty home page, then tapped on display whole history (translated from my language; YMWV). But OCD striked out, and I went back to the empty home page, to repeat the same process again. And again...
Until I ended up with the history appearing back, out of seemingly nowhere. So I wiped everything in the app itself (clear browser data), which works OK everytime. And now disconnected the phone from data before wiping the history and co files. And then went back to the history icon routine: now, without data, the history doesn't appear back. Then, I activated data anew, went on the repeated history checking, and bang: history appears right back...
So, when one tampers when Chrome history and co files, it seems Chrome restores those from the Internet, most probably from Google. Even though I set web history to off in my Google settings... Also tried History Cleaner Pro for root app, and end up with the same exact behaviour from Chrome. For what is worth, I use latest everything, factory 5.0.1, rooted, up to date Nexus 6.
Seriously: what's that crap?!?! Do you observe the same behaviour? Do you know of a way to teach hygiene to Chrome? Not sure I'll be touching the thing again though, even with a barge-pole... There may be a way to clean Chrome (would it be manually, in the app itself, which works as far as displaying information from previous sessions), but this experience tends to make me believe Chrome will save the history and all kind of crap at Google's, even if it doesn't display it anymore in the browser, even when you ask Google not to manage your history. And I surely won't have that. Back to Firefox, I am.

Well, I don't care so much about them recording what I do as about them forcefully flinging that crap back at me... that's what annoyed me. Anyway, yeah, stopped using Chrome, and won't go back to it.
I am looking for specific date on History Brower. Dates before and after appear but there is a gap. Any ideas how to restore these missing dates.

Censorship is also a quite a problem. So many search results get axed because the copyright mafia deems its infringing on their multi-billion dollar project copyrights.
Ironically, even Bing fares better than google and bing belongs to mcrosoft.
agreed. I use bing as my default search engine in browsers. As for Chrome, if OP is still interested, and their isnt an browser sync option in settings>accounts>google, you can use an app like disable services to disable com.google.chromesync.... or something along those lines. you'd have to look thru and find it in GooglePlayServices
Are people still having this issue with not being able to clear google chrome browser history on android?
If so, I found a way to clear it. I will be making a video tutorial if interest with this issue is still in demand. If so please don't hesitate in responding.
I'm trying to free up internal storage space on my Galaxy S4. Using ES Explorer, I found that the phone contains 9830 document files of various types! I find it hard to determine which files are associated with specific apps. Does anyone know of an easy method to determine which files I might delete.

I would not start deleting files I don't know about. Delete the ones you know for sure what they are for and you know that you don't need them.
For example, some old pictures (assuming you have a backup). Maybe some old downloads and some music.

Oh yeah, I'm very wary of just deleting files without knowing their association. Have moved pictures & sound files that can be moved. It's just going to take a lot of time.

Deleting a few dozens of large files will get you more space, than deleting thousands of small ones. And also deleting one small file could lead into some unexpected behavior of some app you would not notice now, but later.
That's why it's easier and safer to start with file you know you created and large enough to see benefits right away.
Most of those documents are app documentation. Best not touch them.
There are, however, a few other things to try that are usually overlooked when clearing up space.
- Delete the .thumbnails folder in DCIM. (You'll need to enable hidden files in file explorer to see it.) This stores a thumbnail of every image on your device and SDcard, deleted or not. Usually amounts to 6-7GB...
- Dial *#9900# and select 'Delete dumpstate/logcat' in the menu that appears. Those can amount to 2-3GB.
- Delete the Cache for the Browsers, Facebook, Maps, Instagram, Youtube, Maps etc. The Cache often isn't counted in the Total App Storage, so you can't see it. Go to Settings> Application Manager > All, click on the app and hit Clear Cache. (Clearing data deletes your profile and resets the app; the cache is just temporary files.)
- Clear the Google Play Services data. Go to Settings > Application Manager > Google Play Services. Click on Manage Space. Hit Clear All Data. Contrary to the warning message, this does not affect your account, Gmail, calendar or contacts.
- Clear the Cache of the phone. Boot into Recovery and select Wipe Cache Partition. This is just temporary files, no actual app or data is affected.
- Go to Settings > Storage. Tap on Cached Data. This'll open the Delete option. (Mine just now was 1.8GB... ). Might give a Security Policy error and appear to do nothing, give it a minute. You can also hit Used Space to see what uses the most space, and hit Miscellaneous Files to see the separate folders that use up space. Select the ones you know for certain are useless (Old apps, for instance) and tap on the bin icon to delete. (Thumbnails was listed here for me as well.)
That should clear up a few gigabytes.
P.s. This'll list Google Play Services, Package Helper and some other processes in your Battery usage as high usage for a minute or two. That's normal. The apps have to actually work for a change

Excellent tips. I seem to remember seeing a few of these before.

So I'm having an issue on my GS6 where every time I switch between running apps, they will reload. Even if I only have two apps running. Say Disa and Chrome. I'll send a message in Disa, then switch to chrome and chrome will reload instead of just having the previous page already open. Then I'll switch back to disa, and disa will relaunch instead of just being at the previous conversation.
I suspect it's running out of memory. Task manager apps show chrome and disa using only a combined 55MB, and only 700MB total are available out of 3GB.
Where is all my ram being used ? Even a list of all running background services (Outlook, cerberus, phone) shows maybe 400MB in use. Why are two apps consisting of 55MB reloading when 700 are available?
Worst part is when switching I can lose data, such as when writing this post then going to look at task manager, coming back in to chrome all of this text will be wiped out.
Issue has carried over from lollipop.
Thanks!
Whether you are concerned about Privacy or just that Facebook is consuming most of your limited mobile data, these 10 settings got you covered.
Well, if You log into the Facebook App (in this case Android App) here are my top 10 settings that you should Change and my reason for telling you to change it.
#1 SAVE YOUR LOGIN INFO (ON THIS DEVICE)
DON'T DO IT at least for security reasons. If you log out of the device, your login info still remains there if you didn't wipe Facebook app data and that could lead to a security breach.
#2 TURN OFF LOCATION.
Facebook uses your location for mainly ads and other kind of profiling so, always turn it off. That doesn't mean that Facebook won't know your location but at least they'll have to do a little more work to Get it (as I'll show later)
#3 TURN OFF START VIDEO IN TIMELINE WITH SOUND FROM SETTINGS
Anyway, this mainly serves Facebook interest were ads that pop up on timeline plays Automatically. At least, give yourself the chance of being the one to click on an ad because the title is catchy or the thumbnail interesting.
#4 TURN ON OPEN LINKS EXTERNALLY.
You should be the one to choose which browser opens URLS from inside Facebook App. If not, Facebook will automatically track your browsing history, activities and behaviors
#5 CLEAR YOUR BROWSING HISTORY
Since you have turned on open links externally, it is important that you also clear any browsing history left on Facebook.
#6 AUTO PLAY VIDEOS ON MOBILE DATA AND WIFI
May not be bad if you are on unlimited data plan but come on, on mobile data too? by default? Not a good news if you are on limited data. Moreso, this dumps a lot of data on app cache.
#7 & #8 ADS PREFERENCES
Ads Preferences setting is interesting because it has a lot of settings on by default that makes you want to wonder why they are on by default. There are two major parts I looked at here - Your information and Ads settings you just have to turn everything off.
#9 OFF-FACEBOOK ACTIVITIES - TURN IT OFF!
This one is so deep we made a YouTube video for it you just have to turn it off.
#10 Privacy settings.
There are loads of settings in the privacy settings that you need to change by default. You really need this one...

What great advices thank you
Or else, uninstall the Facebook crap and use a browser with an ad-blocker to access. Better yet, delete the application altogether. With the number of times, Facebook has leaked user data, I would advise to not use it at all.
