Hi @Raman.V, I don’t think this is the case. I would rather get the firmware versions for G4 and update process confirmed by Aqara support team.
The FW 4.0.6_0018.0068 reported by Aqara app as up-to-date is actually quite old (I suppose it may be even 1 year old). Even here within Aqara forum I can see references to various later FWs (e.g. 4.0.6_0024.0072, 4.0.6_0030.0078, 4.0.6_0044_0092) and as I mentioned, my other doorbell is running 4.0.6_0046.0094.
So it seems to me that the FW update process for G4 is quite inconsistent (see G4 Doorbell no longer recording after firmware update? where 3 users report different FW versions as up-to-date).
