With the cheaper Galaxy Z Fold6 FE all but confirmed to arrive in September this year, Samsung is doing everything it can to set the cheaper alternative apart from the premium Galaxy Z Fold6. Like its predecessor, the latter will include S-Pen support, something that will be missing in the FE variant. X leaker @Tech_Reve says it could get a Titanium chassis.
If true, it brings the Galaxy Z Fold6 even closer to the Galaxy S24 Ultra. An earlier leak (from the same person) said it would launch with the Ultra's 200 MP camera sensor. Leaked renders of the Galaxy Z Fold6 showed off a camera module layout similar to that of the Galaxy S24 Ultra. However, Samsung runs the risk of increasing the Galaxy Z Fold 6's weight with a titanium chassis.
Then again, JerryRigEverything's teardown of the Galaxy S24 Ultra shows that it only uses Titanium for the outer rails and not for the entire chassis. Unfortunately, a wider inner display for the Galaxy Z Fold6 seems to be off the cards. You may have to look at the Pixel Fold 2 or Xiaomi Mix Fold 4 for extra screen real estate.
