My banking app recognized that it was a custom rom (because of tracking which AP blocks) and won’t work.
Also GPS set through third pary apps doesn’t work properly (that service is under AP “umbrella” too).
Those problems don’t exist on official 2.4.1. version, I checked multiple times on multiple smartphone models.
On 2.3. AP works fine, unofficial (T) and official (S) version. In fact, only on 2.4. version I first encountered this problem.
