GT 30 5G vs K12
It depends
Too close to call outright
These two are within 2 points overall, so it depends on you: keep phones for years → GT 30 5G (supported until Aug 2028); want maximum speed → K12 (Qualcomm Snapdragon 7 Gen 3 (4nm)).
Value Score: GT 30 5G 72 · K12 70 — methodology
The lifespan decider
When specs are close, support length decides it — this is what each phone costs per month of safe use.
Category by category
Both displays are effectively the same class.
Performance is a wash — same chip tier.
Camera systems are comparable on paper — pick by sample photos.
Battery capacities are close enough not to decide this.
The GT 30 5G is supported until Aug 2028 — 3 months longer than the K12.
Pound for pound, these two are equally good deals.
