Your phone is very slow or freezes

  1. Restart your phone

    Reboot (power cycle) your phone by holding down the phone’s power button for 10 seconds.

    If it’s a timely issue with the operating system or an app, the phone will be able to reload everything to work properly. 

    If the phone is frozen, and you cannot restart it, try a force restart. 

    The key sequence to complete a force restart can vary from one phone model to another. It’s usually a simultaneous combination of keys. 

    To know the one for your phone, make an internet search using the keywords that correspond to your phone. 

    Ex. Force restart Samsung S10

  1. Install the latest update

    Download and install the latest software update of your phone’s operating system.

    This update is usually available via your phone’s menus.

    The steps to get the latest update can vary depending on the type of phone. Here are two examples:


    Android: Settings → Software update

    iPhone: Settings → General →  Software update

  1. App issue

    Try uninstalling any app you recently installed on/in your phone. 

    An app that is corrupted or developed with a bug could be slowing down your phone or cause it to freeze. 

    In this situation, waiting for a revised version of the app from its provider will be necessary. 

  1. Restore your phone to its factory settings

    IMPORTANT: Save all media, contacts, apps and text messages that are archived and want to keep before proceeding.

    Some of your phone’s parameters will need to be reconfigured after: mobile data blocking, NPA, Wi-Fi settings, Bluetooth function etc.


    The steps to follow to reset your network settings will vary depending on the type of phone. Here are two examples:

    Android: Applications → Settings → General management → Reset → Reset settings → Click on Reset settings

    iPhone: Settings → General → Reset → Erase all content and settings


    Check whether the issue is still there before configuring and personalizing your phone, or installing apps.
