There are times when users get an authentication error while they connect to a Wifi network. The problem is mostly found in Android whenever a device tries to establish a connection to Wifi. If your device is also experiencing an authentication problem Wifi, then don’t worry. It can easily be resolved. In this post, we will make you familiar with the root cause for the Nokia C02 Wifi problem and how you can resolve whenever authentication error occurred on your device.

Part 1: Any idea about the Wi-Fi authentication problem?

Wi-Fi authentication has to be done every time you wish to connect to a Wi-Fi network over your smartphone or laptop. To authenticate yourself and connect to the protected Wi-Fi network, you need to have the password of it. But if after you’re putting in the correct password and still experiencing the wifi authentication problem. Here’s what you need to know.

Authentication error occurs when the “deal” between the Wi-Fi router and device fails due to certain reasons. First, the Nokia C02 device sends the password of the network and the “connect” request in an encrypted format to the Wi-Fi router. Then, the router decrypts the password and compares the password saved on it. Now, if the password matches, it sends affirmation for the “connect” request, and then the Nokia C02 device is allowed to connect to the network.

Part 2: Why Authentication Error Occurred when Connecting to Wifi?

There could be plenty of reasons for facing an authentication error on your device. Most of the time, it occurs whenever a Wifi router seems to malfunction. Furthermore, if your phone has been recently updated, then chances are that there could be an issue with its drivers. A security attack can also make your device malfunction as well. An unstable connection or a router blockage can also be a reason for this issue.

In this scenario, whenever you try to connect to a Wifi network (even after supplying the correct password and username), it doesn’t connect to it. Instead, it displays an authentication error occurred promptly. Thankfully, there are plenty of ways to overcome the authentication problem Wifi.

Use static IP address instead of DHCP

DHCP, or Dynamic Host Configuration Protocol is the default IP address assignment for the Wi-Fi settings on many devices. Whereas DHCP can cause IP address conflict during the dynamic IP address assignment. So, you’d better change “DHCP” to “Static” to see if the authentication error persists.

Step 1: Head to the “Settings” of your Nokia C02 and then opt for “Wireless and Networks” followed by “WLAN/WiFi”.

Step 2: Now, hit on the WiFi network that is showing “authentication error occurred”.

Step 3: Depending on your Nokia C02 model, look for “IP Settings” and tap on it. Now, switch the “DHCP” to “Static”.

Step 4: Note down the static IP address fields and wipe off all the fields. Punch it in again and then save it.

Check carefully for duplicate Wi-Fi names before you connect

Perhaps, you might connect to a WiFi with a similar name. There are good chances that some users do not modify their WiFi network name and possibly, your neighbor may have the same WiFi network, service provider. Therefore, ensure you connect to the correct WiFi network.

Reset the Wifi network

One of the easiest ways to fix the authentication problem of Wifi is to reset the network. To do this, you would be required to forget the respective network first and then connect to it again. This can be done by simply following these steps.

1. Firstly, you need to forget a Wifi network. To do it, go to your phone’s Settings > WiFi and network. From here, you can see a list of all the Wifi hotspots that your phone connects to. Select the network you wish to forget.

2. When you would select a network, it will provide the basic information related to it. Just tap on the “Forget” button and agree to the pop-up message. This will erase the network’s information from your device.

3. Afterward, turn on your Wifi again and tap to the network you wish to connect to. Simply provide the credentials and tap on the “Connect” button to reestablish the connection. This way, you can reset the network successfully.

Modify network connection

If the above solution won’t work, then you would be required to walk the extra mile to fix the Nokia C02 Wifi problem. After you reset a network connection, if still getting issues regarding the authentication of the network, you need to modify the connection. In this technique, you will be changing the IP settings on your phone to alter the way it establishes a secure connection. You can do it by following these steps.

1. To start with, visit your phone’s Settings and open the Wifi page.

2. This will display a list of all the Wifi networks that are associated with your device. Just long-tap on the Wifi network that you wish to modify. It will open another pop-up window. From here, tap on the option of “Manage network settings”. Sometimes, users also get an option of “Modify network settings” here as well. Simply select it to proceed.

3. It will display basic information related to your Wifi network. Just tap on the “Show advanced options” button to access more options related to the network setting.

4. From the IP Settings menu, change the field from DHCP to Static. This will let you establish a static connection between your device and the router.

5. As soon as you will change it to static, you will get different fields related to your network’s IP address, gateway, DNS, and more. Simply fill these fields and tap on the “Save” button once you are done.

Now, try to connect to the Wifi hotspot again. You would be able to overcome the authentication problem of Wifi.

Change Network Security Type

It has been observed that, when we connect to Wifi, our device chooses a wrong security type. This clashes with the default security protocol of the router and authentication error occurred due to this. If your device is facing the same issue, then it can be fixed by simply changing its security type. To do this, follow these instructions:

1. To change the security type of a network, you need to “Add the network”. If you already have the Wifi network saved, then simply forget the network by following the above-mentioned tutorial.

2. Now, turn on your device’s Wifi and tap on the option of “Add network”. Here, you would be asked to give a network name and select the security type. To manually select it, tap on the “Security” option.

3. From here, you will get a list of various security protocols that you can pick. Select “WPA/WPA2-PSK” and save your selection.

Now, try to connect to the network again. Most likely, it will let you fix the authentication error on your device.

Update Android firmware to the latest

There are instances where an outdated OS version of your Nokia C02 may create a hindrance in establishing a connection between your device and the WiFi network. You need to update your Android firmware to the latest version and then check if the problem persists or not.

Step 1: Launch “Settings” of your Nokia C02 and then get into the “About Phone” option.

Step 2: Now, opt for the “System Update” option. If the update is available, get your device updated to the latest OS version.

Restart the router and reset Android network settings

Sometimes, the WiFi router may hang up while establishing a connection and therefore, the wifi authentication problem occurs. Try restarting your Wi-Fi router and then check if your device connects successfully. If this doesn’t work, try to reset your Android Network Settings .

How To Fix Part of the Touch Screen Not Working on Nokia C02

You probably touch the screen of your phone hundreds of times per day. It’s no surprise that smartphone touchscreens are one of the most common components to fail, given their delicate glass construction. However, a part of the touch screen not working on your Nokia C02 does not necessarily mean it is a hardware issue. There could be other reasons why your Android’s touch screen stopped responding.

If your phone’s touchscreen frequently fails to respond, there are several things you can try before calling a professional. This article will reveal those proven fixes you can easily perform independently.

Part 1. Why Is Part of My Screen Not Working

There are two possible causes as to why your phone’s touch screen is not working. One is the touch screen may have been damaged, and the other is the Nokia C02 device may be experiencing technical difficulties.

If you drop your phone and it becomes stuck against something, the touch screen’s connectivity may fail. Only a part of the touch screen may sometimes become damaged and unresponsive. That may also occur when there is a technical failure, such as the phone hanging. A part of the touch screen not working can occur when malware is downloaded or when phone settings are changed.

Now, the problem can affect any Android phone, and users may encounter the following error messages on their respective phone models:

• Nokia C02 P40 lite half touch screen not working
• Nexus touch screen not working
• LG screen is unresponsive to touch
• Nokia C02 left side of the screen is not working
• Redmi’s whole screen is unresponsive to touch

Part 2. Different Types of Touch Screen Issues and What You Should Check Before Fixing

You may experience a variety of touch screens not working on Android issues:

• A certain part of the touch screen is not working.
• Your touches do not register on the touch screen.
• The touch screen incorrectly responds to your touch.
• Half touch screen is not working.
• The touch screen becomes frozen or hangs.
• The screen flashes, flickers, or remains blank.

• Before continuing, make sure your screen is spotless.

Part 3. How To Fix Part of the Touch Screen Not Working (No Physical Damage)

If you have already tried running the Nokia C02 device in diagnostic mode and verified that it is not physically damaged, then the problem is most likely technical. If your Nokia C02’s screen is not responding to touches for technical reasons, follow the methods below to resolve the issue.

Restart Your Device

When your touch screen stops working, the first thing you should do is restart your device. The operation is known as soft resetting. You cannot turn your device off from the option on the screen because the touch screen is not responding. Here are the steps to take.

Step 1: Hold the “Power” button until the Nokia C02 device turns off.

Tip: If you hold down the power button for a few seconds, you will see the “Power Off” and “Restart” options on the screen. You can’t use it because the entire screen isn’t responding. Hence, you should press and hold the “Power” button for as long as necessary.

Step 2: When the Nokia C02 device turns off, wait a few seconds.

Step 3: Press and hold the “Power” button to restart the Nokia C02 device.

Check to see if the Android auto touch screen is not working problem has been resolved. Otherwise, proceed with the following methods.

Turn On Safe Mode

You should switch to Safe mode whenever an application or piece of software causes a problem on your device. Only the most fundamental system components are loaded and used when operating in Safe mode.

If your touch screen is functional in safe mode, the issue is most likely internal. You can quickly fix the Android touchscreen issue by following the prompts given below to activate the safe mode:

Step 1: To force a restart, press and hold the Nokia C02 device’s “Power” button for an extended period.

Step 2: Maintain pressure on the “Power” button. Take your finger off it once you see the manufacturer’s logo.

Step 3: When you let go of the “Power” button, press and hold the “Volume Down” button. After that, a “Safe Mode” label will appear in your screen’s lower-left corner.

Turn Off Developer Options

Every smartphone is bound to have limitations. However, smartphone makers include a “Developer Options” menu for advanced users. Here, restrictions are removed, and user preferences can be customized.

If you enable Developer Options on some Android devices, they may stop working properly. If you have recently activated Developer Options and your touchscreen is no longer responding as expected, you should disable it. To do so, follow the instructions below:

Step 1: Launch the Settings app on your device.

Step 2: Select the System menu item, which usually locates at the bottom of the screen.

Step 3: Tap the Advanced options menu, then select Developer Options.

Step 4: You will then find the switch to turn it on or off. Disable itby toggling the button off.

Step 5: Restart your device to check if the part of the touch screen not working issue has been resolved.

Reset Device to Factory Settings

Resetting your device to its factory settings will return it to its state when you first unboxed it. All your phone’s data and installed apps will be erased, including any malware on your device that may be causing the issue to occur. Here’s how to restore your device to factory settings:

Step 1: Since your touch screen is not working, you can factory reset it using Google’s Find My Device web service.

Step 2: Go to Find My Device from any device and sign in to the Google account associated with the damaged screen device.

Step 3: After successfully logging in, you will see your device’s name. Select the Erase Device option.

Step 4: Confirm by pressing the Erase Device button.

Nokia C02 Camera Not Working Unexpected Error? Fix It Now

For all its glory and goodness, the Android OS often has its users pulling their hair in frustration at just how buggy the OS can be at times. So, if you’re having one of those days today, we are here to help. Camera app is one of the most used apps on smartphones today. People only launch the app when they want to take a photo, for everything else there’s a dedicated photo gallery app. What happens when you launch the camera app only to realize it threw an error and you missed your photo moment? Don’t throw the phone, not yet. Let us help you out.

Part I: Why Is Android Camera Not Working?

There are a few reasons why the camera app is not working on your Nokia C02.

Low Memory

Camera app does rely heavily on system resources, so in case you have too many apps open and for some reason the OS is not able to manage the resources appropriately for the camera app to function as it should, you will get a camera error.

Low Storage

The camera app needs storage space to save the photos it takes. So, in case your phone is running low on storage space, the camera app would likely malfunction as it would have no way to store the photos it would be taking.

General Bugs And Glitches

OS bugs and general glitches within the OS and the camera app can cause camera not working issue anytime during everyday operation. This is part and parcel of any technology.

Hardware Issues

In the rarest cases, there might have developed an actual hardware issue with the camera system on your Nokia C02. The likely culprit is misuse and abuse, such as a dropped phone or maybe the phone was too hot for extended periods of time, causing hardware issues.

Part II: How To Fix Android Camera Not Working Issue?

So, how to get the Android camera not working problem solved? There are a few ways you can try fixing the camera not working issue on your Nokia C02 right where you are, without needing to take the Nokia C02 device to the manufacturer’s service center.

II.I: Restart The Handset

One of the first things to do any time an app or your phone or tablet does not work like it should, restarting the Nokia C02 device refreshes everything just enough to resolve most commonly occurring issues.

Use the power button on your smartphone to restart your Android handset and see if this resolves the issue.

II.II: Close And Relaunch The Camera App

If the camera app (or any app for that matter) has been in the background for a while and then it is brought to the foreground, there are always chances of it crashing for any reason, or not working as expected. So, closing the app completely and relaunching it is recommended.

Step 1: Launch the app switcher on your specific Android device the way your device manufacturer suggests you to. Usually, it is a swipe up and hold gesture to get into the app switcher.

Step 2: Next, you can choose to close just the camera app or, better yet, close all apps by tapping the Close All button. Flicking any app upwards (quick upward swipe) is how you close an app. If there is no Close All button anywhere, repeat the gesture for all open apps.

II.III: Check App Permissions

These days, thanks to strides in the privacy initiatives, apps need permissions before they can function the way they do. Most of the times, apps such as camera do have the necessary permissions, but sometimes it is possible that the permissions are set incorrectly. To check if the camera app has the requisite permissions, do the following:

Step 1: Go to Settings > Apps > Camera > Permissions.

Step 2: Tap Camera.

Step 3: See if the selected option is Allow Only While Using This App. If not, select it.

II.IV: Clear The Camera App Cache

Clearing the camera app cache is sometimes helpful. To do that:

Step 1: Go to Settings > Apps > Camera and tap Storage Usage.

Step 2: Tap Clear Cache.

II.V: Clear The Photo Gallery App Cache

The camera app is closely tied to the photo gallery app that comes baked in into Android OS. That is because photos that the camera app takes are stored in the photo gallery app. Consequently, if there were any issues in the photo gallery app, that could lead to the camera app not working on Android problem. Here’s how to clear the photo gallery app cache:

Step 1: Go to Settings > Apps > Photos > Storage Usage.

Step 2: Tap Clear Cache.

II.VI: Check For App Updates

This does not happen always, but sometimes, with known bugs and issues, there may be an update released that fixes those bugs and issues that prevent some users from using a given app reliably. Checking for updates is a good step to make sure that your camera app is updated to the latest version possible.

Step 1: Go to Play Store and tap your profile picture on the right.

Step 2: Tap Manage Apps and Device.

Step 3: If there are updates available, Tap Update All to update all apps.

II.VII: Cool The Phone Down

We do not realize the immense power that is packed into the thin smartphone form factor these days. If you have been using the phone to video chat for a while now, you might not realize that the phone has become hot, especially if you are using a desk stand. Same for shooting high-resolution videos; the phone does get quite hot shooting high-resolution videos.

If this is the case, close all apps and let the phone cool down. You might even want to shut the phone off to help cool it faster.

II.VIII: Nudge The Camera System

You may want to tap your camera system (the lenses and surrounding area) gently to see if that gets the camera working. In case it did, this is indicative of a hardware issue, and you should get it checked at the service center at your earliest convenience.

II.IX: Fix Android Camera Not Working Issue In One Click (With Dr.Fone)

Now, if the above fixes have not worked, you might want to repair your Android OS once before you make that appointment with the service centre. And, we have just the app to help you fix your camera not working on Android problem quickly.
