Guar gum, a plant colloid, costs less than agar and is better suited for growing thermophilic bacteria, but is also more difficult to handle, being more viscous and less transparent. The bacterial polysaccharide xanthan is cheaper as well but forms weaker jellies that, as with carrageenan, might result in puncturing its surface. Other colloids, like alginate (from brown seaweed) and gellan gum (from a bacterium), don’t set solely based on temperature and require additives for gelation. These additives might interfere with microbial growth and make the preparation of those jellies less handy than agar plates.

Samsung has tweaked the design a bit this time by rounding the corners to align them more with the S26 Ultra's look. The base model has a slightly larger display than the S25 at 6.3 inches, though the S26+ still has a 6.7-inch screen (albeit with a higher resolution than the S26 can handle). The S26 has a larger battery capacity than the S25 too at 4,300mAh.
