Get your phone WhatsApp ready for Qfast

To ensure you have the optimal setup to use your phone with Qfast, follow these guidelines :

  • Ideally dedicate an Android / iPhone for use with Qfast. Preferably perform a factory reset if an old phone is being re-purposed.
  • Install WhatsApp Business App from the respective playstores
  • Configure WhatsApp and set your profile picture. Please refer to the guide on WhatsApp image sizes for your profile picture.
  • Connectivity : We highly recommend to connect through stable Wifi always and keep Cellular Data as backup. 4G/3G is recommended for best performance.
  • Charging : Charger should be connected to phone , dont allow battery go below 40%. Use auto cut off charger or phone to avoid damage to battery/phone. In case battery or phone dont support auto cut off when fully charged we recommend to unplug the charger for few hours and when phone battery drops to about 50% plugin again.
  • Low Brightness : Keep the phone brightness as low as possible , when you are sending message your screen may turn on momentarily. Dont lock the phone.
  • Disable battery optimization or saver if enabled , if your phone feature allows to whitelist app to never restrict battery or background data usage then please whitelist WhatsApp. Starting from Android 6.0 , Android introduces two power-saving features that extend battery life for users by managing how apps behave when a device is not connected to a power source. Doze reduces battery consumption by deferring background CPU and network activity for apps when the device is unused for long periods of time. App Standby defers background network activity for apps with which the user has not recently interacted.
  • You need to manually disable the Doze mode if your Android version is above 6.0 the option will be in the Settings -> Battery -> Battery Optimization -> Select WhatsApp Business and Disable Optimization
  • Remove App Optimizer/Saver Anti Virus Apps – Uninstall battery/memory optimizing/antivirus/security apps like CleanMaster, CoolerMaster, NetGuard, memory saver, Security etc. on the phone. These apps may cause un-expected issues
  • Remove Unwanted Application –  As mentioned earlier, we highly recommend to keep only Whatsapp Business on the phone and uninstall or disable or other applications on the phone for the best performance.
