When we covered the Galaxy S26 Ultra red-tint fix five days ago, the caveat at the bottom was that replies under Samsung’s own community post suggested the correction had not cleared the discolouration for everyone, and that owners should look closely at their panel after updating rather than assume it was handled. Since then a second set of reports has surfaced, and it is a stranger one: a handful of Galaxy S26 Ultra owners say small dot-like marks have appeared on their displays after the colour calibration was applied.
What Galaxy S26 Ultra owners are reporting
The description in both write-ups is consistent: small dot-like marks showing up on units that have been through Samsung’s colour calibration, which Sammy Fans places near the top portion of the screen. Crucially, that calibration reached owners by two different routes — the over-the-air August 2026 update, which began rolling out in South Korea on 26 August, and the free in-person calibration Samsung offered at Korean service centres while the software fix was being prepared. The reports do not separate the two, so it is not established that the OTA specifically is involved. Some of these units may have been calibrated by a technician weeks before the update existed.
It is also worth being precise about how much evidence this is. Sammy Fans published the reports on 28 August and Gizmochina followed on 31 August without adding fresh cases; neither names the forum, thread or user the reports originated from. That is one body of unattributed user complaints being relayed twice, not two independent findings. As of 31 August, neither outlet reporting the marks cites any Samsung comment on them.
What is actually established about the red tint
The original defect is well documented: a rectangular patch of reddish cast in the middle of the display, most visible on white backgrounds at high brightness under strong ambient light, which owners began flagging a few months after the phone’s March 2026 launch and which built into a real volume of complaints through July. Samsung’s response, as relayed by outlets covering it, was that the cause is software rather than a hardware defect — not burn-in, not panel degradation, and not the Ultra’s new Privacy Display hardware. Gizmochina goes further and characterises Samsung’s position as pinning it on the colour optimisation and calibration routines, with prolonged use at maximum brightness under intense light able to push the balance off on some units. That specific explanation is the outlet’s own account of Samsung’s reasoning. No Samsung-authored statement on the cause has surfaced in the coverage — the company’s global newsroom listing carried nothing on the red tint or the calibration programme when it was checked on 31 August — so there is no company wording to check the explanation against.
The remedy has two halves. The software correction ships in the August 2026 update, which is rolling out from Korea outward, and Samsung’s position is that most owners will not need to do anything beyond installing it. For those who want it sooner or whose panel does not respond, Korean service centres have been offering same-day calibration free of charge regardless of remaining warranty.
What to do if you see marks on your S26 Ultra
Nothing here is a reason to skip the August update. It carries the month’s security patch alongside the calibration, and a small number of unverified reports is a weak argument against the month’s security patch. But it is a reason to actually look at your screen after installing, on a plain white background at high brightness, rather than assuming a fix marketed as automatic has worked.
If marks are there and they persist across a restart, do not wait to see whether they multiply. Book a service-centre inspection and get it on record while the phone is inside warranty. That matters because of how these two problems interact: a phone whose display fault is officially classified as a software issue is a phone whose owner may be told to install an update and go away. If the panel still misbehaves after the software fix, the software explanation has stopped covering it, and that is a hardware conversation. Getting an inspection logged now is what makes that conversation possible later.
The free calibration programme, for what it is worth, has so far been described only in a South Korean context. Owners elsewhere waiting on the OTA should see it over the coming days as the rollout widens.
