What at first might seem like a small update that would bring with it numerous and necessary bug fixes so that the Android system would work better and finally avoid this lack of performance on some devices, finally appears with some very interesting news. related to safety and improvement in audio quality when we are talking on the phone.
From the same blog, Google announced yesterday the appearance of Android 5.1, an update that improves stability and performance and offers features such as support for multiple SIM cards, Device Protection and HD voice for compatible phones. Very remarkable is the fact that under Device Protection a device with Android 5.1, if for whatever reason it falls into the hands of someone else's friend, it will allow even if a wipe of the internal memory of the phone is made, when trying to install a new ROM and the Play Store is accessed, the original account will be requested, locking the phone.
Few news but interesting
We recently met how Google backed down for not forcing manufacturers to encrypt Android 5.0 phones due to the problems that this data encryption was giving in the performance of some of the Nexus, for which it is no longer available by default in the new phones like some Nexus devices.
While we had been a bit misplaced with what is security in Android, with the appearance of Device Protection in Android 5.1, we will have an important layer of security and protection when the device is lost or stolenas it will remain locked until the Google account is entered even if someone were to reset the device to factory settings. This feature will be available for all Android 5.1 phones and tablets.
Voice calls in HD which is included in the 5.1 significantly improves audio quality for compatible devices such as the Nexus 6 itself. And what is the support for multiple SIMs is another novelty that will allow better management of telephone costs with different rates.
To finish with the little news, the quick access to Wi-Fi network controls and Bluetooth paired devices through the quick settings in the notification bar.
Stability and improved system performance
We cannot forget that it is possibly the best of this update for those who have a Nexus and saw how performance was reduced due to certain bugs like the 'memory leak' that apart from decrease the speed with which you browse with your device it also led to higher battery consumption. This bug has been fixed as well as many others that will allow a better Android experience with a Nexus and other Android terminals that are updated to Android 5.1 Lollipop.
If you have a Nexus 7 2012 Wifi, a Nexus 10 or a Nexus 5 you can install the factory image available a while ago through this entry posted less than 30 minutes ago.
