Lollipop Android is already in virtually all Nexus devices, but this does not mean that a lot of bugs that have not yet been solved but, gradually, with version 5.0.2, performance has increased markedly appear. If you still have problems with your phone, check out the most common solutions.
And WiFi connectivity problems
The truth is that this problem tends to occur at each update of Android and above all, on virtually any device. The solutions, though, are quite temporary such as turning on and off airplane mode, forget and reconnect to the WiFi network ... However, one of the most pleasant solution is to manually choose between using the bands 2.4 and 5 GHz , clear the cache and do a factory reset the Nexus 5. The initial cause is still unknown although some users point to incompatibilities with applications, but most important is that the real solution lies in the hands of Google.
Applications close unexpectedly
In this case itself usually happens that the usual culprit is the application itself. To fix just have to go to Settings -> Applications and clean the cache it. If the problem persists, we can go further and reinstall the application or restart the Nexus 5 in Fastboot mode and wipe cache partition before rebooting "reboot".
Bug when trying to perform a factory reset
This unfortunate bug is present in version 5.0 of Android Lollipop, although later it was solved by updating to version 5.0.1. Since then, the Nexus 5 have not been having trouble resetting other terminals-nor his memoirs.
Problems with battery consumption
Another drawback that normally appears when updating the devices. The simplest solution to back up your data and applications, install the update and do a factory reset. After that, restore the data back and enjoy a Lollipop experience without bugs.
High consumption of RAM
The simplest solution would be to wait for the global update to Android 5.0.2 which is resolved occurs. However, if you want to make the process already, all you have to do is enter Fastboot mode, open the Recovery mode and press the power button then select wipe cache.
Silent mode
It is one of the missing features in Android Lollipop. However, there are simple applications like Silent Mode Lollipop to achieve the same effect.
