Well, it was unclear how the company bring this massive capability to foldable phones even after having several flexible parts as well as the hinge. Meanwhile, our friends over at TheVerge revealed the internals of the Galaxy Z Fold 3 that expose Samsung’s strategy of IPX8 rating on foldable.

First, the company has developed a “special lubricant” for hinges that “adheres very well to all small parts in the device.” This lubricant protects all components in the hinge from corrosion.
This lubricant protects all components in the hinge from corrosion. For foldable displays, Samsung uses pressure-sensitive adhesive to seal them.
With these two measures, even if water enters the Galaxy Z Fold3 5G or Galaxy Z Flip3 5G, it will flow between the screen and the two parts of the phone without causing any damage.

Besides, the company has also developed a thick double-sided tape to seal all the openings in the folding part, which allows the screen to move slightly when folded and unfolded while preventing water from entering the part.

Lastly, to prevent the lines connecting the two parts of the mobile phone from being corroded by water, Samsung uses “cured in place gaskets.” These gaskets are more flexible than ordinary rubber gaskets, allowing the line to move more greatly, and at the same time making the line waterproof.

What about third-party repairability?
According to TheVerge teardown, these waterproof designs will make Galaxy Z Fold 3 5G and Galaxy Z Flip 3 5G more difficult to repair, which is also the price to pay for IPX8 waterproofing.
Samsung could launch the Galaxy S23 FE smartphone in August or September this year. This information is arriving from a trusted German blog – winfuture.de, which has a solid track record of Samsung leaks.
According to the information, Samsung started testing Galaxy S23 FE prototypes at the end of April. Usually, phone makers begin this procedure about three months before the market unveiling of the product.

The Galaxy S23 FE carries the model number SM-S711, while its internal codename is R11. The primary camera is getting upgraded to a 50-megapixel sensor, while other sensors may remain the same as the Galaxy S21 FE.
Earlier, it was reported that the Galaxy S23 FE will be equipped with Exynos 2200 processor. It’s the same processor, which Samsung used in European models of the Galaxy S22 series.
Another rumor claims that the Snapdragon 8 Plus Gen 1 may be used in the company’s next-gen affordable Galaxy S phone. It will help Samsung maintain the price point and offer decent performance alongside.

Samsung is the only Android vendor, which shares almost every new flagship feature with older models through firmware updates. So far, the company rolled out a lot of new Galaxy S23 features to Galaxy S22, S21, and even the S20 series while enhanced camera animation is coming too.
According to the latest info, Samsung will roll out enhanced camera zoom animation from the Galaxy S23 smartphones to the Galaxy S22 series. As of now, there’s no such information regarding the distribution, however, it could happen in the near future.

Samsung community moderator and in-charge of Camera operations confirmed that the Galaxy S23 will be supported for Galaxy S23’s smooth camera zoom animation. Before the rollout, the company will notify users about the schedule through a community post.
In particular, the Galaxy S Ultra models are equipped with quad camera sensors, which the phone uses as per zoom adjustments. In the latest S23 Ultra, the sensor-shift animation is way too smooth compared to its predecessors, which will be coming to the S22 series, at least.

It looks like Samsung’s Galaxy S series is the victim of the terrible green and/or pink lines issue. Consumers of Galaxy S20 Plus are already facing the problem and now it’s popping up on its predecessor. Following the May update installation, some Galaxy S21 users reported green/pink lines problems.
According to user reports, their Galaxy S21 series smartphones have also become the victim of the green/pink lines issue, which appeared on the Galaxy S20 lineup. And even those annoying display lines have appeared without any kind of drop or external damage/water insertion.

Samsung released the Galaxy S21 in early 2021, and the lineup has completed two years of launch at this point. As the devices got out of warranty, it becomes a pricey concern to get the screen replaced, as it could cost approx $300 in the United States.
Consumers say that they first noticed a single colored line on the screen, which further expanded with the second colored line. As Samsung consumers are aware of the display problem, they are not making efforts to solve it through a firmware update, as it’s not a solution at all.
The Galaxy S21 series models are quite expensive and Samsung should acknowledge the problem. A free screen replacement program should be opened for Galaxy users where they can reach and get their phones checked. If found it manufacturer defect, the screen should be replaced free of cost.
