Google presents the next major version of its mobile operating system with key innovations. We have summarized the most important ones for you.

EnlargeAbove all, Android 5 “Lollipop” also brings some interesting new features to the user interface.

In mid-October 2014, Google introduced Android 5 “Lollipop”. In March 2015, Android 5.1 followed as a "Service Release", with which the first errors in Android 5.0 were fixed and minor improvements made. The quick settings have been spiced up and support for HD Voice and dual SIMs has been added.

Android 5.1: That brings the update

At the end of April, Google started to provide the new operating system version Android 5.1 for mobile devices. With the update, suitable smartphones and tablets get new functions that, among other things, should make life more difficult for thieves.
The new device protection is supposed to ensure that a stolen Android device remains locked even if the thief has reset it to the factory settings. Only when a user logs in with the original Google account can the android be unlocked again. Google promises this function for the Nexus 6 and Nexus 9. According to Google, it should also be available on most androids that are shipped with Android 5.1.

In addition, the so-called wear detection is used for additional protection: the function uses the accelerometer of your smartphone to determine whether you are still wearing the device on your body. If not, the smartphone will be locked. If you want to give the phone to someone else, you have to unlock it first. If the person puts the device down, it is automatically locked.

Multi-SIM card support, HD video calls & Co.

Another new feature is multi-SIM card support. Android 5.1 now also natively supports smartphones that have multiple SIM card slots. Previously, smartphone manufacturers had to implement this function themselves.
Video calls should be possible with Android 5.1 with HD resolution, provided that Android 5.1 is installed on both communicating smartphones.

Further improvements relate to the quick access to WLAN and Bluetooth settings: Both functions have new submenus in the update, which you can now call up directly via the quick settings.

In addition, Google promises, as always, that the update should improve the stability and performance of Android devices: For example, with Android 5.1, the Snapdragon 805 built into the Nexus 6 should always use all four cores in the future. Programming errors had also led to crashes and loading delays for some users.

The update to Android 5.1 should also improve power consumption. However, the update is unlikely to help users confronted with the error known as the memory leak. This bug causes apps to quit their service due to the overflowing memory. An update for this problem is still pending.

Last but not least, the update to Android 5.1 brings some cosmetic corrections such as various stylish animations, new icons for the volume settings, an improved message bar and an optimized lock screen.

These devices already get Android 5.1

The Android One, the first smartphone with Android 5.1, was delivered in Indonesia at the beginning of February. In this country, the update is currently available for the Google devices Nexus 5, Nexus 6, Nexus 7 (both variants) and Nexus 10. The update for the Nexus 9 was announced at the time of going to press.

The update for the Motorola smartphones Moto E (2013), Moto G (2013 and 2014), Moto Maxx and Moto X (2013 and 2014), the HTC M7, M8 and M9 as well as the HuaweiHonor 6 was also announced High-end models Samsung Galaxy S6 and the S6 Edge donate the update, nothing is known about other models from the manufacturer.

Sony is rumored to provide Android 5.1 for the Xperia Z, Xperia Tablet Z, Xperia Z1, Xperia Z1s, Xperia Z2 Tablet, Xperia Z3v, Xperia Z3 Tablet, Xperia Z Ultra Google Play Edition, Xperia ZL and Xperia ZR models. Nothing is known about the Xperia Z2, the Xperia Z3 and Z3 Compact yet. However, all three models have already received the update to Android 5.0.2 Lollipop, which has similar innovations to Android 5.1. So an update would not really be necessary; the Z4 will probably get the update.

By the way: If your smartphone is not updated to Android 5.1 or 5.0, you can do this yourself with a custom ROM. You can find out more about this in this guide.

The central goal is uniformity

Previous Android versions were heavily influenced by the respective hardware provider. Up to now, every manufacturer has provided its own user interface: the smartphone user interface of a Samsung Galaxy differs significantly from that of the HTC or LG device families. This should change with the new surface called "Material Design". Google made it more modern and optimized many surface objects. Thanks to the flat design used, everything looks fresher and more modern. However, it remains to be seen to what extent Google will influence the surface design of the manufacturers.

Google wants to simplify the switch from one Android device to another with a uniform interface. This uniformity is now established with Apple and iOS as well as Windows smartphones. But a lot has happened under the surface as well. Android 5.1 is based on the Linux Kernel 3.14 and supports the Open GL ES in version 3.1. Google provides over 5000 programming interfaces for developers.

10 tips & tricks for Android Lollipop

Always informed through "Notifications"

Google is promoting a number of innovations with the slogan “The right information at the right moment”. This goal is implemented by means of "Head Up Notifications", which provide information about incoming messages, such as new mails, while an app is running. Specifically, these are small windows that overlap the current application. If you are interested in the information at the current time, then tap the notification field. This takes you directly to the app that displayed the message. Otherwise, the message disappears from the screen with one swipe.

News are also displayed on the lock screen. At this point, too, direct access to the reporting app is possible. If you are overwhelmed by the amount of information, the notifications can be reduced to the essentials using filters.

Multi-user system and higher security

EnlargeMulti-user system: everyone can create their own account on family tablets. The special "guest" account can always be reset to its original state if requested.

Android 5.1 allows several profiles with different permissions. This is less interesting for smartphones, but more interesting for tablets that are shared. In the delivery state there are two users: the primary user account and a guest account. You can create additional user accounts within the "Settings", with the choice between a full and a limited account.

If you set up a new account, this user has to set up his profile from scratch. He can then load and configure independently of the other apps. However, restricted accounts lack the right to change general device settings. Changes to the profiles can be deleted at the end of the session.

When it comes to device security, there are some innovations. The new Android offers data storage encryption. The corresponding settings can be found under the heading "Security". This means that your personal data is better protected in the event of theft. Encryption is automatically activated on new devices; updates on older devices must be activated explicitly. Warning: The encryption cannot be reversed. The only option is to reset the device, in which case all data will be lost.

The HTC One M9 costs around 750 euros, the Samsung Galaxy S6 Edge even up to 1050 euros. But it can also be cheaper: Many manufacturers show smartphones with top features at the MWC, which still only cost up to 300 euros. Dennis and Takis took a look around the fair and found the 6 best bargain smartphones.

Another interesting function is "Smart Lock": This is available to you after you have set up the lock screen. As soon as the screen lock is activated, the device is automatically locked after a preset time. Alternatively, it can also be locked manually using the on / off switch. Smart Lock automatically deactivates the device lock if one of three conditions is met: The device is in a trustworthy location, or a trustworthy device is nearby, or the device recognizes a previously defined face.
