Have been wanting to switch to this but have certain apps that I have to use for work and I'm too ignorant to know if regular apps will work on this OS? Can anyone inform me of whether or not some of these apps would work? They're not any apps that would be widely known, they are specific to my job but can be found on the Play store. Any help would be appreciated. Thanks!
In general, the majority of apps should work on a de-googled phone (lineage, graphene, calyx, etc). That said, there are a few apps that require a feature called SafetyNet to ensure the system hasn't been modified. Apps with this feature will not work and are generally limited to banking/financial type apps.
That's useful information. None of these apps that I use are financial in any way. If anything they're more like GPS apps that route me to where I need to go, etc. I'll look more into it before I make the leap. Thank you for answering.
They don't have to be financial - many corporate apps will not work on custom ROMs - the most popular ones being the ones by Microsoft - eg Teams, Outlook etc.
Similarly, some games may also not work, such as all the ones by Niantic (Ingress, Pokemon Go etc) and typically many online multiplayer games.
Finally, this will also affect popular streaming media services, such as Netflix, Amazon Prime etc.
There are workarounds for some of these - some with certain compromises - but there's no guarantee that they'll continue to work. So before you look into any workarounds (if you use the above three categories of apps), know that it's a constant game of cat-and-mouse, so it's not for the faint hearted.
Just my two cents I ran lineageos on my oneplus 6 for the last 3 months before getting a new phone, also running micro GApps and I was able to use my banking app and things like android auto just fine.
