[TUTORIAL] Safeguarding data on Android

This is our last little tutorial for beginners before we quietly move on to the Flash techniques on Android I’ve been promising you for a few months.

Today we’ll learn how to make a simple safeguard of your apps and data with a view to an upcoming reloading of your Smartphone, and even a simple reloading of factory default settings. Because reloading is fine but keeping your saved games, safeguarding your contacts, your SMS or even your favorite websites is better and if it’s only a matter of a few clicks, why do without ? 😉

Android-Titanium-Backup

To achieve this goal, there are many techniques and applications but in our particular case, I will specifically use Titanium Backup and SuperBackup SMS and Contacts which, in my opinion, are the most powerful and most accomplished applications. The only problem with Titanium Backup is that you’ll have to route it so that the application works. To do this, follow this tutorial. Another prerequisite is an external SD card ; on a Flash, the device’s SD memory will be formatted and, as a result, deleted.

Structure of application data

Before launching on technicalities, let’s make a little summary of the data’s structure on Android.

Your applications, when you instal them, will be lodged in the main partition allotted to the system and noted « / », in a file located in /Data/app, unlike the pre-installed software in the phone and which are located in /System/app.
The downloaded data necessary to your software stock themselves in the Sdcard0 partition, in Android/Data or obb, which is very often, today, your external SD card, if you have one, unlike the phone’s inner memory which will then be located in SDcard1. However, there are a few instances where it works the other way round, this particular phenomenon being caused by your /etc/vold.fstab which runs your cards’ mount points.
Your software data, linked to the Android file shown above are stocked in the system’s / root, in /Data/Data, and they’re the data Titanium Backup will retrieve, and the data located on your external SD card will be used again when you reboot the device.

How to proceed with Backup

When you launch the application, you go to a home page. There, choose Save/Restore. All your system applications will be listed. Select the box top right and we’ll get to the heart of the subject.

Here, two submenus are of interest to us – Save and Restore. Titanium enables us to do many more interesting things but we’ll deliberately not talk about it today.

In these submenus, you find GO boxes. Select the one directly facing your chosen option. As for myself, I only use Save all user’s applications, without taking the data system which, in case of reinstallation, might give you some trouble and other undesirable bugs. It is very important to understand that, here, user applications means application + data. Once you have selected GO and see a listing, select the applications you want, click on the green check mark top right and voilà, the restoration will launch and stock itself in Sdcard0/Titanium Backup. Your safeguard procedure is over.

Same thing with the restoration – GO, Restore applications, green check mark top right, and the restoration starts. The only problem is that you’ll have to validate one application after the other, unless you’ve subscribed to the commercial version featuring the hypershell and its automatic installation. If you have two hundred applications, you should prepare a Thermos bottle, a snack and a few cigarettes, if you are a smoker. 😀

Superbackup SMS and Contacts

The first good news here is that you won’t need the root. The second good news is that the application also allows you to safeguard your applications. On the other hand, I don’t know if it will retrieve data therefore, as I’m this doubt, I’ll stay on Titanium.
Here are several interesting options.

SMS Backup : safeguards your SMS
Contacts Backup : safeguards your contacts
Call Logs Backup : safeguards your calls’ logfiles
Calendars Backup : safeguards your info in the calendar
Bookmarks Backup : safeguards your favorites on the web browser.

For every one of these options you can simply safeguard (Backup) and restore (Restore). Choose the Backup that interests you the most, a file name will be suggested to you, indicating the path to it. Usually, it’s /storage/SDcard0/SmsContactsBackup. Click on Ok and it’s done.The procedure is the same if you want to restore.

So much for safeguards today but please remember this method works for application data only. Manually copy your photographs, music files, videos and documents. If you don’t, the flash will lose them. I wish you all a good Backup. See you next Thursday, same time, for my first tutorial on Flash by FlashTool on Windows.

Meizu – Ubuntu Partnership Confirmed, MX4 Also Underway

In a former article we discussed a rumor and some clues hinting that Meizu and Canonical, Ubuntu OS’s company, were negotiating a partnership agreement in order to fit with Ubuntu the make’s future top smartphones.

News are coming from Meizu Russia which made it known on mobiletelefon.ru. According to Meizu Russia, their engineer is already developing the Meizu MX3 with a mobile number portability on Ubuntu OS. For their part, Canonical has just announced they are working in partnership with a manufacturer, though they didn’t say which one, with a view to developing an Ubuntu OS for a touch device.

The company is currently trying to build a high-performance Meizu MX3 and stabilize its Linux core. We’ve also learned this phone should go on sale very soon.

A New Flyme OS as a Bonus

meizu-mx3-flyme-os

In addition to Ubuntu OS, Meizu is also about to unveil their own user interface – the new Flyme OS which will go on Meizu MX2 and MX3. This Android-based interface is being tested as of now. We are still waiting for a confirmation but we wonder if it might be used to support the 4G LTE. Indeed, Meizu could also be working right now on their next two-model smartphone, MX4 Pro and MX4 Mini. It’s 4 as in 4G and we like that. It should be fitted with a Mediatek Octa-core processor. The Mini should feature a 5” ‘small’ screen whereas the Pro will have a 5.5” 2K with a 15:9 format.

In other words, things are moving a lot in the usually discreet world of Jack Wong and his Meizu company. Could we be witnessing the waking of a Chinese volcano that has been slumbering for much too long? 😉

Xiaomi MiTV at the Shenzhen Xiaomi Center

Xiaomi.com_
On the occasion of our monthly marriage proposal to Xiaomi at the Shenzhen Xiaomi Center, we discovered the Xiaomi MiTV. (They said no again, lol.)
What we like about Xiaomi is that you can make your choice very fast – an MiTV, a high-performance Xiaomi Mi3 and an entry-level Xiaomi Red Rice.
In between, a Xiaomi Mi2s which has now become obsolete in front of Xiaomi’s latest challengers.

Xiaomi MiTV – a full HD 47” 3D display at 2998rmb

Selling a Chinese television set in a country already abounding with many different makes at various prices could be deemed a risky bet.

Only the fame of the make and a tight price could make the difference because we think twice before paying 375€…

The MiTV will therefore be half MiTV, half Android Box.

I’m really no expert on TV or TV screens and, as it’s not possible to touch nor take photographs – except if you’re a foreigner and no one dares to forbid it or even merely speak to you^^ – we’ll then be content with a very fine display and a definition we’d like to see more often for that price. 😀

So, the Xiaomi MiTV is a 47in, Full HD 1080p 3D slab, manufactured by Samsung and LG, fitted with a Qualcomm Snapdragon 600 quad-corenot 4G, lol – 1.7GHz, 2Go RAM DDR3, 8Go ROM eMMC 4.5, featuring Wi-Fi Direct, Miracast, Airplay, the DLNA, the Samba network share, a Dolby Digital DTS 2.0 audio system, and, of course, a Rom MIUI TV.

And like all Xiaomi products, there’s none to be found, or none in stock, and you’ll have to recourse to Xiaomi’s flash sales if you want to be lucky enough to buy one for 2999 yuans, i.e. 375€.

To conclude – these Xiaomi people are really good.

Xiaomi Mi3 Now Available at China Unicom

It’s good news for the stocks because the Xiaomi Mi3 is now coming to China Unicom stores – therefore WCDMA – it’s good news, yes, except that –
Posters are there but promotion hasn’t started yet.
You can’t find the Xiaomi Mi3 in the stores yet.
Its price hasn’t been revealed yet but it should be a little bit more expensive than on the Xiaomi website (yes, here too).
Actually, there may be no Xiaomi Mi3 in stock, which means buyers will have to make reservations then go to the stores when they’re available.

To put it short – more expensive than on the web, even maybe as expensive as the prices at alternative retailers and with uncertain delivery deadlines – such is the sweetness of buying a Xiaomi Mi3 in a store.
