The initial sync of OsmocomBB is (as far as I remmber) setting the AGC to an expected signal level of -85 dBm. If "your base station" (I assume it is not a public network, but a base station you have on your desk / in your lab) is next to your phone, you might have -45dBM or even more. This will clip the signal. Unfortunately in all the 6 years of OsmocomBB, nobody voluntered to address any of those long-standing issues or lacking features. It continues to sadden me that despite all the efforts that people like Dieter, Andreas, Sylvain and I have put into implementing the first >= 80%, the rest of the community and user base has not managed to address those remaining parts. The AGC handling for initial sync is one part, and the re-sync to neighbor cells (as requirement for hand-over) is another of those key parts.
