I've been getting an error notification every time I back up my phone for the past 8 months. I remember a couple of months ago, someone posted an article about how to fix that. Any chance someone can help me or direct me to that post ?
Also understand that there you might still have issues after following that guide, if that happens, remove apps that don't work during back up (for me it was messanger) other apps like WhatsApp and wechat have a back up option.
Also do use the search feature next time or Bing/Google
