We just bought her phone recently. It would be nice to have to buy a new one. Is it necessary to worry about the US-Huawei scandal?
For already with Playstore activated smartphones, Google says that the functions remain.
The trade war should affect there only on new devices.
The whole scare tactics in the media is hardly ridiculous.
There will be no more Android updates or security patches, but nothing more. Whether it would have existed before at all is also questionable. Less expensive devices get hardly any Android updates anyway.
Android 9 will still be available for the P20 Lite.
And you can ignore all this "soon no Whatsapp more" news. Even if the apps can no longer be obtained from the Play Store, they can still be installed.
In 3 months the whole thing looks quite different anyway.
There are no updates anymore.
If you are someone with the modding of cell phones, especially Kernel Replace etc. Knowing you can install on the thing just Vanilla Android or LineageOS on it.
Since Android is OpenSource and you own the hardware of the phone yes, you can decide for yourself which operating system you install on the phone, so you do not necessarily rely on the support of Huawei.
The essential thing is hald, that the phone nacher no longer has a guarantee, because it is just not as far as in PCs with these things, that you can easily install another operating system.
