iOS Update Problem: Unable To Check for Update

Many iOS users from around the word always make sure that their iPhone 6 are up to date which is done by going to Settings app, General then Software Update. They check updates for their iOS devices to get new iOS 9.3.2 features and run their devices smoother. But most of the users encountered a problem. This error says “Unable to check for update. An error occurred while checking for a software update”.
This error appears on the devices of users who try to connect to Apple’s servers for iOS update. Good thing is that there is a solution to this problem, and users who wish to update their devices to the latest version may do so.
How to Solve Update Problem – Unable to check for update
After too much persistence until the number of users checking Apple’s servers subsides, you still get an error Unable To Check Update.
Solution 1:
Try hard reboot by holding both the power and home buttons at the same time until you see the Apple logo on the screen. Wait for few seconds before you turn your device on again. Now check if it already allows you to check for new updates.
Solution 2:
Before updating to the latest iOS 9 update, make sure that you already backed up all your contents and data to avoid any data loss in case something goes wrong during the process of updating.
Step 1: On your PC or Mac, launch iTunes. Wait for an alert which will inform you of the latest version available.
Step 2: When the alert appears, simply click Download and Update button. This will start the download and updates on your device.
Solution 3:
Make sure that you have internet connection. Some devices recognize WiFi with strong connection, but there is no internet. Try to unplug your router and plug it after a minute.
Solution 4:
Reset your network settings. Go to Settings and choose General. Tap on Reset then select Reset Network Settings. This will only erase data about internet connections on your device such as WiFi and WiFi passwords, and cellular data. After resetting, connect to your WiFi again and try to check for new software update.
Solution 5:
Try changing your DNS settings.
From Settings App, go to WiFi and tap the blue arrow beside your current WiFi network. Tap on DNS fiend and enter different DNS server. You can check Google’s Public DNS. After doing this, try if you can already check for latest update.
