Google rolled out the monthly Android security update for Nexus devices on April 4, which patches 29 known issues including security vulnerabilities with Nexus devices.

Google started releasing monthly security updates for Nexus devices in August 2015 as an effort to fix issues as soon as possible rather than waiting for a major update.

"Nexus devices have always been among the first Android devices to receive platform and security updates ... Nexus devices will receive regular OTA updates each month focused on security, in addition to the usual platform updates," said Google.

"We have released a security update to Nexus devices through an over-the-air (OTA) update as part of our Android Security Bulletin Monthly Release process," said Android. "The most severe of these issues is a Critical security vulnerability that could enable remote code execution on an affected device through multiple methods such as email, Web browsing and MMS when processing media files."

The April security patch also fixes privilege vulnerabilities in Bluetooth, Wi-Fi, Setup Wizard and the Download Manager. The patch also updates a few Qualcomm hardware vulnerabilities that may result in "permanent device compromise."

Although Google has announced the rollout of the patch, it can take up to a week for the update to reach all devices. Owners of Nexus devices including Nexus 6P, Nexus 5X, Nexus 6, Nexus Player, Nexus 9 (LTE), Nexus 9 (Wi-Fi), Nexus 5, Nexus 7 2013 (Wi-Fi), Nexus 7 2013 (Mobile) and Nexus 10 who have not received an OTA update can download the factory images from the Google Developer website.

Nexus device owners who have not flashed their smartphone or tablet should note that flashing can wipe out existing data. Customers who want hassle-free installation should wait for the OTA update.

Mobile phones are also used for conducting financial transactions and many customers have their bank card details stored in handsets. Many people also exchange confidential emails, documents and messages via smartphones. Compromise of personal information can lead to identity theft.

Google recommends that Nexus owners should install the security patch even though it does not bring new features to the table. The latest security update keeps a device up to date and safe from attackers.

In mid-March, Google released an emergency security update for the Nexus 5 and 6 after reports of a safety liability that was found in a rooting app.
