Heat in a folded body
Owners report the Z Flip6 running warm on the charger, in video calls and on camera. The compact body traps heat, and dimming and throttling follow, so take off a thick case and move a hot phone out of sun.

What is true of this model and changes how you fix it

The crease and the cover screen
A visible crease can show after months of use, and the cover screen limits which widgets run. Lines on the cover screen after a hinge repair are a known complication of that repair.
Short battery life and slow charging
Reviewers call the Z Flip6's battery life and charging speed underwhelming for a flagship, so a day that ends early is partly the hardware.
Cover-screen limits
The cover screen runs a limited set of widgets, especially from third parties, so a missing widget is not a fault.

Questions that only have an answer for the Samsung Galaxy Z Flip6 and Flip5 family

Is the crease on a Galaxy Z Flip6 a defect?+

A faint crease is expected on a folding screen. A deep or growing one, or lines across the cover screen, is worth a Samsung service check.

Why can't I add my app to the Z Flip6 cover screen?+

Samsung limits which widgets run there, especially third-party ones, so a missing one is a limit, not a fault.
