Posted by Samsung’s Galaxy S27 lineup is still unannounced, but a new leak has offered one of the clearest looks yet at how RAM and storage could be divided across the Galaxy S27, S27+, S27 Pro, and S27 Ultra. The headline is simple: 12GB of RAM may become the baseline across the family, while the top Galaxy S27 Ultra could reserve 16GB RAM for its 1TB version.
The information is being attributed to Korean leaker Lanzuk, who reportedly compiled details from Weibo and South Korean industry sources. Samsung has not confirmed the configurations, so they should be treated as early product-planning information rather than final specifications.

Galaxy S27 Series RAM and Storage Leak – Quick Comparison
The reported configurations are straightforward, but there is one major difference between the Pro and Ultra tiers: the Ultra’s 1TB version is the only model in the leak paired with 16GB of RAM.
| Model | RAM | Storage Options | Reported Memory / Storage Standard |
| Galaxy S27 | 12GB | 256GB, 512GB | Not confirmed; reports point to older standard |
| Galaxy S27+ | 12GB | 256GB, 512GB | Not confirmed; reports point to older standard |
| Galaxy S27 Pro | 12GB | 256GB, 512GB, 1TB | LPDDR6 / UFS 5.1 under consideration |
| Galaxy S27 Ultra | 12GB (256/512); 16GB (1TB) | 256GB, 512GB, 1TB | LPDDR6 / UFS 5.1 under consideration |

What the Leak Suggests for Each Galaxy S27 Model
Galaxy S27: 12GB RAM and a Possible 256GB Starting Point
The standard Galaxy S27 is tipped to come with 12GB RAM and either 256GB or 512GB of storage. The most notable part is the absence of a 128GB option in the main leak. If Samsung follows this plan globally, the entry-level S27 would start with twice the storage of some earlier base configurations.
For context, PehlePakistan’s current Samsung Galaxy S26 listing includes 128GB, 256GB, and 512GB storage with 12GB RAM. That makes the rumored 256GB starting point one of the more practical changes in the new leak.
Galaxy S27+: Familiar Capacity, No 1TB Tier in the Leak
The Galaxy S27+ is also listed with 12GB RAM and 256GB or 512GB storage. That would keep its capacity structure simple and position it between the standard model and the more storage-heavy Pro and Ultra variants.
The current Samsung Galaxy S26+ already uses 12GB RAM with 256GB or 512GB storage, so the leaked S27+ configuration would be familiar rather than a major capacity upgrade.
Galaxy S27 Pro: Up to 1TB, but Still 12GB RAM
The rumored Galaxy S27 Pro is the most interesting middle option. It is said to offer 12GB RAM across 256GB, 512GB, and 1TB storage tiers. That means buyers could get Ultra-level storage capacity without moving to the Ultra model, although the Pro would reportedly stay at 12GB RAM even at 1TB.
Because Samsung has not officially announced a Galaxy S27 Pro, both the model itself and its position in the lineup remain subject to change. The leak should therefore be read as a possible product plan, not a confirmed replacement for any existing Galaxy S model.
Galaxy S27 Ultra: 16GB RAM Appears Reserved for 1TB
The Galaxy S27 Ultra is tipped to use 12GB RAM on the 256GB and 512GB variants, while the top 1TB model could move to 16GB RAM. In other words, buyers wanting the maximum memory may have to choose the most expensive storage tier as well.
That structure would be close to the current Samsung Galaxy S26 Ultra listing on PehlePakistan, which already offers 256GB, 512GB, and 1TB storage with 12GB or 16GB RAM depending on configuration.
LPDDR6 and UFS 5.1 Could Matter More Than Capacity
The leak is not only about how many gigabytes each model may have. Reports also claim Samsung is considering LPDDR6 RAM and UFS 5.1 storage for the Galaxy S27 Pro and Galaxy S27 Ultra. However, those component choices are reportedly not final, and Samsung could limit the newer standards to selected higher-capacity variants if costs remain a concern.
If LPDDR6 does make it into the final phones, the improvement would be about speed and efficiency rather than just a larger RAM number. Samsung Semiconductor describes LPDDR6 as a next-generation low-power memory standard designed for higher bandwidth and more efficient AI workloads. That could help with multitasking, on-device AI, sustained performance, and power use – but those benefits cannot be attributed to the Galaxy S27 series until Samsung confirms the hardware.
The same caution applies to UFS 5.1. Faster storage can reduce app loading times and improve large-file transfers, but the Galaxy S27 Pro and Ultra are not officially confirmed to use it. The final memory technology could also vary by model, storage tier, or market.
What This Leak Could Mean for Buyers
- 12GB RAM may become the common baseline across all four reported Galaxy S27 models.
- The standard Galaxy S27 could start at 256GB instead of 128GB, if the leaked global configuration is accurate.
- The S27 Pro could be the only non-Ultra model with a 1TB storage option.
- The 1TB Galaxy S27 Ultra may be the only configuration with 16GB RAM.
- Newer LPDDR6 and UFS 5.1 technology may be reserved for the Pro and Ultra, or only for selected higher-end variants.
- Storage capacity may stay familiar on several models even if the underlying memory technology becomes faster.
What Pakistani Buyers Should Know
There is no official Galaxy S27 price, Pakistan launch date, PTA status, or local storage lineup yet. Even after a global launch, Samsung may sell different variants in different markets, so a leaked international configuration does not guarantee that every version will reach Pakistan.
If you plan to import a Galaxy S27 model after launch, check the PTA mobile registration and tax guide before calculating your total cost. Imported flagship phones can carry a significant registration cost in Pakistan, and the final amount depends on the approved model and registration method.
When local or imported units eventually become available, verify the device before paying. Our guide on how to check PTA approval by IMEI explains the 8484 and DIRBS checks used to confirm whether a phone can legally connect to Pakistani networks.
What Is Still Unconfirmed
The leak gives a useful early picture, but several important details remain open. Samsung has not officially confirmed:
- The final Galaxy S27 model lineup, including the reported Galaxy S27 Pro.
- Whether 256GB will be the base storage in every market or whether some regions will receive different variants.
- Whether LPDDR6 and UFS 5.1 will ship on all Pro/Ultra storage tiers, selected tiers only, or not at all.
- Official chipsets, camera hardware, battery sizes, charging speeds, and display specifications for the full lineup.
- Pakistan pricing, launch timing, PTA registration status, and official retail configurations.
For now, the safest reading is that Samsung appears to be keeping RAM capacity relatively conservative while exploring faster memory technology for its higher-end models. The final product mix can still change before launch.
