If that doesn't work, you'll want to check your charging cable. If you're using a third-party charger, try using the charger your Nexus device came with. If you are using the stock charger, try using a charger with the same voltage.
You can also try swapping out the wall charger for a USB cable. Plug your Nexus device into a computer and charge it.
How to Fix Android Nougat Wi-Fi Problems
Surprise, surprise. Some Nexus owners are running into Android Nougat Wi-Fi problems. This actually isn't much of a surprise given that Wi-Fi problems are among the most common issues for phones and tablets.
If you're running into a Wi-Fi issue while on Nougat, the first thing to do is check your router. We recommend unplugging your router for a solid minute before plugging it back in to see if that helps resolve your issue.
If you can't do this because you're in a public place or if you're positive it's not a router issue, try these fixes.

First, you'll want to go in and forget the Wi-Fi network giving you problems. Head into your Wi-Fi settings, either in the Settings menu or via Quick Settings and select the desired Wi-Fi connection. Choose Forget (this will make your device forget the password so make sure you know it) and then reconnect to see if the connection improves.
If that doesn't help, we recommend updating your applications. And if that still doesn't help dislodge your Wi-Fi issue, you'll want to boot your Nexus device into Safe Mode in an effort to single out problem apps. Apps have been known to cause issues with connectivity and they could be causing the problem on your device.
How to Fix Android Nougat Bluetooth Problems
Bluetooth problems are also extremely common on Nexus devices and we're seeing complaints about Nougat Bluetooth issue as we push away from the release.
If your Bluetooth connection(s) starts acting up, try turning it off then back on again to see if that helps. Believe it or not, this can sometimes remedy the problem.
If that two second fix doesn't work, you'll want to go in and forget the Bluetooth connection causing the problems. Head into your Settings, select the Bluetooth device and tap on Forget. Try reconnecting to the device.
If this doesn't work, try booting your Nexus smartphone or tablet into Safe Mode. Again, to do this, follow Google's instructions. Safe Mode will disable third-party apps and help you isolate potential culprits. There's a chance one of your apps is causing the problem.
If that remedy fails, you can try wiping the system cache (instructions above) or factory resetting the device. These should obviously only be used as a last resort.
How to Fix Android Nougat Data Problems
Android Nougat data issues are popping up for some Nexus owners and we expect complaints about cellular data to continue throughout the year.
Fixing Android data issues can be a bit tricky but here are a few things to try before you contact customer service.
If you're positive, absolutely positive, that these data issues have nothing to do with an outage at your carrier/Google/another service, try a simple reboot. Power down your device and turn it back on and see if that helps.

If it fails, try switching the device to Airplane Mode. This will turn off all of your connections. Turn Airplane off and see if that helps establish your connection.
If that doesn't help, go into your Settings. Go to Wireless & networks and head into Cellular networks. Try toggling Cellular data/LTE off and on.
If you're still unable to get cellular service, you'll need to get in contact with your carrier or Google. If they can't help, you might have to perform a factory reset.
How to Fix Android Nougat Performance Problems
If you start noticing abnormal amounts of lag and stuttering with Android 7.0 or Android 7.1.1 Nougat on board, try these fixes.
We recommend clearing your cache partition if you haven't done so in awhile. The instructions are located near the top of this page.
This is a proven fix for lag issues and it's worked for us and our Nexus smartphones and tablets in the past.
If that doesn't help your device's performance with Nougat, you can try using an application like Qualcomm's Trenpn Profiler to monitor your device's CPU activity.
You might also use Nougat's new RAM Manager tool located in Settings > Memory. This tool allows you to see what might be slowing your device down.
You can also try deleting files that you no longer need and cutting back on the amount of widgets you're using.
If you can't find a permanent fix, it might be time to backup your files and perform a factory reset to see if that helps.
How to Fix Android Nougat App Problems
Nexus users are running into issues with various apps after installing Android Nougat. App issues are extremely common after a new operating system is released.

If an app starts acting up, the first thing to do is check for an update. Developers have rolled out Nougat support updates with features and fixes and there's a good chance the new version will help iron out your problem. Just be sure to read reviews from Nougat users before you install.
If that doesn't help, and you can't find anything on the developer's forums/website (for instance, SoundCloud has a community forum and Spotify has a help page dedicated to Android problems), get in contact with the developer so that it's aware of the issue.
How to Fix Android Nougat Sound Problems
If your sound stops working properly after you download the Android Nougat update, there are a few things to try before performing a factory reset.
First, try a simple restart. Reboot your phone or tablet. More often than not, this will only temporarily fix the issue.
If that doesn't work, boot the device into Safe Mode. This will disable third-party applications. There's a very good chance one of your apps is causing the problem with Nougat.
How to Fix Android Nougat Random Reboots
Android Nougat random reboot problems are popping up for Nexus 5x users and owners of Google's other Noguat-powered devices. Fortunately there are a few fixes to try before getting in contact with Google/your retailer for a replacement device.

First, try restarting your Nexus phone or tablet. If that doesn't help, try updating your applications. You might also want to clear App data and cache.
To do that, go into Apps in Settings, click an app, and tap Storage. Select Clear Data and Clear Cache to see if that helps resolve your problems.
If these problems persist, get in contact with Google customer service.
How to Fix Android Nougat Problems If Nothing Else Works
If none of these fixes work for you and your device, there are several other resources to take a look at before giving up.
First, we recommend looking at Google's Nexus Help Forum. There are tons of friendly and knowledgeable users on there. More importantly, there are tons of potential fixes.
If you can't find anything there, we recommend performing a factory reset on the device to bring it back to the way it was when you first bought the device. Just be sure to backup your important files before you do this.
If that doesn't help, contact Google or the retailer where you bought your Nexus device to see what can be done. If you're lucky, you'll get a replacement.
7 Things to Know About the Nexus 5X Android 7.1.1 Nougat Update
Nexus 5X Android 7.1.1 Update: Impressions & Performance
If you haven't seen the Nexus 5X Android 7.1.1 update popup yet there's no need to panic. This is how Google's OTAs work.
Google's OTA updates move out extremely slow and the company's said that Android 7.1.1 will push out to Nexus and Pixel devices "over the next several weeks." Typically, once a roll out for a device begins, it takes about two weeks to reach everyone.
We recently received the Android 7.1.1 OTA notification on our Nexus 5X and we've been poking and prodding the update for a couple of days. Here are our impressions.
We've spent a few days with the Nexus 5X Android 7.1.1 update and battery life appears to be holding up. The device is holding an excellent charge. If recently installed the update note that it sometimes takes battery life a couple of days to settle in.
We haven't run into any problems with connectivity. We've tested the Nexus 5X and its new Nougat build with several ISPs, routers and Bluetooth devices. Our connections remain strong.
We haven't experienced any random reboots or lockups/crashes and we haven't seen any UI lag when navigating around the new OS. The Nexus 5X is still extremely fast with Android 7.1.1 on board.
So far, the November Nexus 5X Android 7.1.1 Nougat build is performing well. We recommend it for most users. If you're feeling leery, track down a second or third opinion before installing the Android 7.0 Nougat update on your phone.
It's also worth noting that Google's started December Android security update is packed into the company's Android 7.1.1 Nougat OTA.
The December security update for the Nexus 5X delivers several key patches for potential exploits. You can check out the changes right here.
