It's within the first week of July and that means the Nexus security patches were due to hit the web any day now, and that day is today as Google has just released the patch for all compatible Nexus devices. For those that don't like waiting on the over-the-air updates to hit devices on their own, Google has kept things similar to last month and has released both the factory images and the OTA images on the OTA page, making it possible to flash the software to your device manually. What Google has done a tad bit different this month is split the security patch for July up into two separate groups, one that was released and labeled with the date July 1st, and one that was released and labeled with the date July 5th.
This might cause some confusion for users who are looking to make sure that they're getting the correct download files for their device, but the good news is that there is essentially not much different about the two groups of patches. When it comes down to it, the July 5th release patch contains everything that the July 1st release patch contains, plus additional fixes for drivers that needed them. Users should end up getting the appropriate patch release for their device, so if it doesn't need fixes for the drivers your device would for example, presumably end up with the July 1st release.
According to the details, there are a decent number of drivers fixes included in the July 5th patch level, and are meant for Android One devices, the Pixel C, and of course, Nexus devices. The driver fixes will apply to a few different hardware types since the fixes are designed for Android One, Pixel, and Nexus devices, meaning the driver fixes will include chips manufactured by Qualcomm which you'll typically find in the Nexus hardware, as well as MediaTek which can be found in Android One devices, and NVIDIA which will be found inside of the Pixel C tablet. As stated users will now be able to flash the OTA and factory images for the July security patch already, or you can simply wait for the OTA to push out to your phone.
