Part 1. Why Is Your Vivo Y78t Stuck on the Boot Screen?

There are countless reasons why a problem happens, just like why your Android phone is stuck on the logo page. This section sieved out the top 3 reasons why your Android boot screen happens and some tips to overcome it.

1. Changes to the Software

Android is a flexible operating system. It allows users to customize it in any way they desire, which is Android’s beauty. The customizable nature of the operating system allows users to unlock, root, flash, and tinker. However, this flexibility in customization might be a double edge sword. Accidental tampering with the Android system might result in software problems, such as being stuck on the Android boot screen.

Fortunately, this is not a complicated fix. Android accepts different fixes and allows the system to return to how it once was. Even with software issues, the system does not get completely inoperable. The best way to fix changes to the software is to start from the beginning of the process. This might offer the best chance for you to restore your phone to normal.

Although it is fun to customize and change the software, following trusted sources ensures you do not damage your phone. Having an Android phone stuck on the logo page is one of the many examples of the problems that might happen if changes to the software go out of hand.

2. Android Software Updates

Updates are a common cause of Android phones stuck on the logo. It happened when the update did not complete as it should have been. Several reasons for incomplete updates, such as poor internet connection, the connection between computer and phone being lost, a power cut, the phone freezing, and the list go on. When an update is uncompleted, issues such as being stuck at the Android boot screen and many others might occur.

Before an update starts, your mobile device will notify you of the duration of the update. As a tip, set aside an additional 10-15 minutes on top of the update duration to ensure your update is completed successfully. It will be ideal for activating the software update only when there is sufficient power in your phone or keep it charging during the update.

When an update is disrupted or stopped before it completes, the existing Android version will become corrupted while the new software to be updated is incomplete. This means that your Vivo Y78t has no system to run on. Always complete your software updates, and you will not have the problem of your Android phone getting stuck on the logo.

To overcome this, locate the app that has been giving you issues and remove the app from your phone. Restart your device, and you should be able to have your Vivo Y78t functioning properly.

Vivo Y78t Not Connecting to Wi-Fi? 12 Quick Ways to Fix

Nowadays, it’s pretty much essential to have your Vivo Y78t or smartphone connected to the internet. Whether you’re watching videos, looking something up, or using any kind of app, you need the internet for these applications to function correctly.

There are plenty of problems you could experience, whether it’s the Wi-Fi network keeps disconnecting on its own without any warning, perhaps a security issue where the passcode or IP address isn’t being registered properly, or even if the connection is just being super slow, even if there’s no reason too.

Luckily, despite there being so many problems out there, there are also many solutions. Today, we’re going to share with you the complete definitive guide to help you get your Vivo Y78t connected and free from problems and issues.

Part 1: Restart your Vivo Y78t

Begin by powering off your Vivo Y78t and unplugging your router. Wait for about a minute before plugging in the router and turning on your device. This simple reset can often restore stable connections and fix Android wifi not working.

Part 2: Turn on Airplane mode and turn off

Turn on Airplane Mode for a few seconds, then turn it off. This maneuver refreshes your device’s network connections and might rectify the Android not connecting to wifi issue.

Part 3. Check Wi-Fi Router settings

The third step you’ll want to take is making sure the internet router in your house is working properly and is actually sending internet data to your Vivo Y78t. Of course, if you have other internet-enabled devices connected to the same router and they’re working fine, you know this isn’t the problem.

However, if you’ve got a problem with Wi-Fi not working on your Android and other devices in your home or office, you know you’ve got a router problem. Here’s how to solve it.

Go to your internet router and check the indicator lights
While this depends on your device, a green or blue light will mean the connection is good, whereas a red light indicates a problem

Part 4. Boot your Android in safe mode

If you’re unable to connect to the internet, but other devices have no issues, you may find the issues is coming from within your Vivo Y78t itself. Fortunately, there are ways you can see whether this is the problem.

The best way to do this is to boot your device in Safe Mode. The process for doing this will depend on the make and model of your Vivo Y78t, but the basic process goes as follows;

Turn off your Vivo Y78t by holding down the Power button and tapping Power Off. Wait a few minutes to ensure the Vivo Y78t device is completely off
Press and hold the Power button to turn your phone on, but the press and hold both the volume up and volume down buttons at the same time

Now you will be booted in Safe Mode. Try connecting to the internet again to see if it works

If your device connects to the internet while in Safe Mode, you’ll know you have a problem with an app or service that’s running on your device. If this is the case, you’ll need to go through your apps and delete them and then reinstall them one at a time until you find the app or service that is causing your internet problems.

Part 5. Check the Android Wi-Fi adapter

If you’re using a Wi-Fi adapter on your device to connect to the internet, you’ll need to make sure this is working. This could be an adapter on your Vivo Y78t itself, especially if you’re using an older device, or if you’re using an adapter to boost the ranger of your router network.

You need to check both of these to make sure your connection is working properly.

If using an Android Wi-Fi adapter, make sure all the Vivo Y78t device drivers are up to date, and if you’re using an app, make sure the app is updated, and all the settings allow an internet connection
If you’re using a router adapter, make sure it’s set up properly, and your Vivo Y78t is connected to the adapter using the correct passwords. Try connecting another device to see if the internet connection is working on there
Whichever method you’re using, try disconnecting your Vivo Y78t and forgetting the network, and then reconnecting and entering the right password to refresh the connection

Part 6. Check SSID and IP address on Android

To make a Wi-Fi connection work, your Vivo Y78t needs to match two codes that connect and relate to your router to establish the connection and work correctly. These are known as the SSID and the IP address.

Every wireless device will have its own codes and making sure they’re matched to the network you’re connecting to is crucial to ensuring the internet is working on your Vivo Y78t. Here’s how to check on your Vivo Y78t to make sure everything is correct.

Tap the Settings menu option, followed by Wi-Fi on your Vivo Y78t
Turn on your Wi-Fi network and connect it to your router
Find the router name (SSID) and make sure it’s exactly the same as the SSID written on your router
Once connected, tap the Wi-Fi network and you will see the IP address. Check both your phone and the router codes to make sure this number matches

When these numbers are matching, if your Android is still not connecting to wifi, you’ll know this wasn’t the problem.

Part 7. Fix Android system issues in one click

If none of the solutions above are working, this could indicate a real problem with the firmware and operating system of your Vivo Y78t. Fortunately, a fast solution to get everything working again is to completely repair the software of your phone.

Part 9. Change the password of the Wi-Fi

Each Wi-Fi network router will give the opportunity to choose and change the password you have to let devices connect to your network. It’s important you try changing this because you never know if someone else has accessed your network and could be blocking your device. Here’s how it works;

Log onto your computer and open your Wi-Fi settings
Depending on the brand and method of your individual router, navigate to the Wi-Fi password settings menu
Change the password to something complicated using all available digits and characters
Save the password and restart the router to disconnect all devices
Now connect your Vivo Y78t to the router using the new password

Part 10. Reset network settings on Android

Just like the method above where you’ll be effectively resetting the network settings on your router, if this hasn’t worked, you’ll be able to reset the network settings on your Vivo Y78t, hopefully removing the bugs and allowing you to connect.

From the home screen of your Vivo Y78t, open the Settings menu
Tap the Backup & Reset option
Tap the Reset Network Settings option
Tap the Reset Network option
If you need to, enter the PIN number or passcode for the Android device, and the Vivo Y78t device will confirm the reset has taken place
Reconnect your Vivo Y78t to your Wi-Fi network for the changes to take effect

Part 11. Clear partition cache in recovery mode

As you continue to use your Vivo Y78t, the partition cache will fill up with data your device needs and doesn’t need. However, by clearing your device’s partition cache, you can make clear up some space which should help your device have enough memory to connect to the internet.

Turn off your Vivo Y78t
Turn it on by holding down the power button, volume button, and home button
When your phone vibrates, let go of the Power button, but continue to hold the volume button
When a menu is displayed, use the volume buttons to navigate the menu
Select the Android System Recovery option, followed by Wipe Cache Partition
Restart your device and connect to the internet

Part 12. Reset factory settings

If worse comes to worst, another option you have is to factory reset your Vivo Y78t. As we’ve spoken about above, while using your phone from the day you started using it, your device will fill up with files and data which can become messy and causes bugs.

However, by factory resetting your device, you can start again from the factory default from which you first received it, ultimately clearing the bugs. Make sure you back up your device before proceeding because it will erase your personal files.

Open the Settings menu on your Vivo Y78t
Navigate to System > Advanced > Reset Options
