Google has warned people not to circumvent the ban on Google apps that affects newer Huawei phones.
Recent Huawei devices cannot download the Google Play app store or hugely popular apps such as Gmail, YouTube, or Google Maps.
Android phones allow users to install apps from unverified sources, however.
But now, Google has warned this “sideloading” – manually installing app files found online – is “high risk”, as the files may have been tampered with.
CCS Insight analyst Ben Wood said Google was right to warn people the practice was “risky”.
“Unless you are 100% certain about the integrity of the app, it is not a risk worth taking,” he said.
