Galaxy Z Fold9 may bring back the under-display camera Samsung abandoned, to answer the iPhone Duo (rumor)

A tipster on X (via GSMArena and Gulf News) says the 2027 Galaxy Z Fold9 brings back the inner under-display camera Samsung used from Fold3 to Fold6 and dropped on Fold7, alongside major internal changes and roughly the same thickness. The same source talks about 3.9mm unfolded and 7.9mm folded. Single source, unconfirmed.
