The phone will not turn on
The phone does not turn on.
The phone is not fully charged
One of the simplest reasons your phone will not turn is low charge. The first thing you should do is plug the phone into the charger. As the device is charging, an indicator will show the amount needed to charge.
If the phone will not power up when it is fully charged, then the issue may be related to the battery or the charger (see topic “The phone will not charge”).
Battery is not correctly installed
If you connect the battery incorrectly then your phone will not power on. To check battery installation, remove the back case (found in our battery replacement guide), align the metal prongs on the battery with the metal prongs on the phone, and firmly press the battery in.
If the phone has charge, the phone will vibrate and power on.
The phone will not charge
The phone will not charge when connected to charger.
Bad cable connection
It is common that the charging cable isn’t connected properly. A proper connection is one where the pieces fit snugly and are not loosened up. To check your cable connections:
- Check to see if the USB connection to the wall plug is securely connected.
- Check to see if the connection between the charging port of the device and the charging head is securely connected.
Dirty charger port
Over time, accumulation of debris in the charging port at the base of the phone may cause the phone to stop functioning correctly. To fix this, shine a light in the USB charging port, and clean with a cotton wrapped toothpick.
The biggest issue of charger failure stems from the USB micro cable. Possible damages include bending at the ends of the cable, which can cause the wires to tear, preventing the charger from charging the phone . If you see visible damages, then replace the cable with a new one.
If the phone will not power on from the other steps, then the battery has likely lost functionality. You can follow this guide to replace the battery.
Screen is frozen
The screen does not respond to touch and/or is stuck on the same page.
System software needs an update
Sometimes software has problems that can often be fixed by installing a new system update.
To check for an available update, navigate to the following pages:
Settings > Software update > Download and install > Update Now
Your phone may power off and restart while installing the update. This is normal and expected.
Too many applications are continuously running in background
Apps can often freeze or lag when too many of some other apps are still running and clogging up memory. Doing a soft reset allows for the device to be restarted without erasing data. The reset closes all applications and clears data in random access memory. Before starting, ensure the device is at least 50% charged, otherwise it may not turn back on after reboot.
To do a soft reset:
- If you can’t remove the battery, hold the VOLUME DOWN + POWER buttons simultaneously for seven seconds, until the phone vibrates. The device should restart and display the brand logo.
- If you can remove the battery (see our battery replacement guide), remove it, wait a few seconds, then place it back in, and turn the device on.
If the device powers on but won’t load the operating system or boots straight to the brand logo, you may have corrupted software. In this case, you should perform a hard reset. A hard reset completely erases all of your personal data off the phone. Ensure the device is charged at least 50%, or it may not turn on after reboot.
Be sure to remember your Google account login information so that you can restore your information from a backup. The Factory Reset Protection (FRP) Lock will not allow you to use the device until you log in again with your Google account.
It is also a good idea to remember the login information for all of your apps so you can access them after the reset.
Be sure to decrypt your microSD card if you have one. Decryption is the removal of an additional security wall that was put in place to protect personal data from being seen should the phone get lost or stolen. Without this step, the reset is not possible, since the data is locked away.
In Settings, search for “Decrypt SD card” > , select >, and follow the on-screen prompts.
To perform a hard reset:
- Turn off the phone: press and hold POWER > select “power off” from menu options
- Press and hold VOLUME UP + HOME + POWER buttons until the logo appears.
- Release POWER only
- Release the rest of the buttons when “recovery mode” screen appears.
- Using VOLUME DOWN button, select “wipe data/factory reset” >press POWER button to confirm.
- Using VOLUME DOWN button, select “yes-delete all user data” > press POWER button to confirm.
- Select “reboot system now” > press POWER to confirm.
- Set up as old device using “Google Account and Password, Backup and Restore”, or set up as new device.
Phone displays “no storage” notification
The device is unable to download applications, take pictures, and hold further memory.
Memory card doesn’t have enough storage capacity for data on phone
The memory card is a small flat drive used in mobile phones that stores digital information. In the ZTE Maven 2, it is located in the back of the phone. It may just need to be taken out and put back in again. Follow our memory card replacement guide.
If the problem persists, you can check the storage capacity of the device to manage your storage.
To check the memory card’s storage capacity for data:
- Swipe down from “notification bar”
- Select “settings” icon
- Scroll and select storage > available internal memory and storage space will be displayed
- Navigate to desired storage location
- Click on desired apps
- Delete unused/unnecessary junk to free up storage
The cache may be full and using storage
The cache is comprised of files, scripts and multimedia stored on your device after opening an app or visiting a website for the first time. It uses memory to store files downloaded directly from the web. When it becomes full, it can take up storage
To clear app cache:
- Swipe down from “notification bar”
- Click the “settings” icon
- Click “apps”
- Click desired app
- Click “storage”
- Click “clear cache”
Memory card needs to be upgraded because of insufficient capacity
Users of the ZTE Maven 2 can purchase a larger memory card to free up internal memory in the phone.
To access the memory card slot, follow our memory card replacement guide.
Issue persists after previous troubleshooting attempts
Transfer files to the cloud to free up storage.
To transfer files to the cloud:
- Swipe down from notification bar and click “settings”
- Scroll to “backup and reset”
- Ensure that "back up my data" and automatic restore is “on”
- Click “backup account” or add an account for a new backup account
- Data will be backed up to this account and will free up storage on phone
