1. Nineasy With Built-In Screen Protector – Strong Shock Resistant – Samsung S21 Ultra Waterproof Case
Ten meters or thirty-three feet of underwater protection means that with this cover you can dive or snorkel with your Samsung Galaxy S21 Ultra. Although the advertised IP68 rating seems insignificant with those stats. An IP68 rated phone is “dust resistant” and can be “submerged in 1.5 meters of freshwater for 30 minutes.”
Despite the case’s impressive underwater stats, it doesn’t feel clunky and obtrusive in your pocket. In fact, it’s as slim as any other waterproof case we’ve ever tested. Another great thing about Nineasy is that it supports wireless charging, so you know you have a samsung s21 ultra waterproof case that is up to date with the latest fads.
Shock absorption comes in a trifecta of adjustments: raised lips to protect the camera lenses, raised edges to protect the screen when placed or dropped, and corner, air cushion technology. I dropped my new cocoon S21 Ultra onto the sidewalk from hip height and it bounced like a football leaving the phone safe and sound. Another feature to mention is the ribbed sides that help keep the phone from falling.
The first advantage of this samsung s21 ultra waterproof case is that you can use it in everyday life without removing it after your dive session. Use it underwater to a depth of two meters / six feet six for up to an hour; it is perfect for shallow diving and snorkeling. The built-in screen protector feels responsive and allows you to take movies and photos with the impressive 8K camera. The good news is that once you get back on your boat, dry the built-in screen and dry your hands, you can use it for mundane functions like swiping and fingering open image galleries.
The samsung s21 ultra waterproof case is made of TPU (thermoplastic polyurethane – read more on Wikipedia) which is ideal for phone cases due to its strength, anti-grease, anti-fingerprint, and abrasion resistance. Ribs on the sides of the case are deeper than with a regular case, making it easier to hold the case in water.
The screen protector has a raised area that protects the camera’s important lenses and is scratch-resistant. The built-in buttons work well on volume controls, so you can see your friends from the water even if you’re dicing up and down beneath the surface, which is sure to make them jealous when you’re in a warm climate.
The Samsung s21 ultra waterproof case works with an original Samsung type-c charger and unfortunately does not support wireless charging, so make sure you are well prepared for your trip and buy the right charger.
The SPIDERCASE has been tested and verified at the military level and protects your Samsung Galaxy S21 Ultra against hard drops of up to two meters / six feet six. For those of you who want to learn more about the military standard, the Spidercase is a military standard, 810G-516 maintained by a tri-service partnership that includes the United States Air Force, Army, and Navy and is always evolving by agreement. This bolsters its number one position in “Best Waterproof Cases for Samsung Galaxy S21 Ultra”.
The SPIDERCASE looks great, in black, and despite its impressive waterproof and shock-resistant properties, it’s not bulky and slips neatly in and out of pockets while not being so lightweight and slick that your phone will fall out easily. All things considered, the SPIDERCASE looks in black and delivers where you need it most, protecting your phone from drops, scratches, and liquid to a decent depth.
3. JOTO Waterproof Pouch for Samsung Galaxy S20 Plus
The unique and lightweight dry Samsung s21 ultra waterproof case is a safe option to protect your phone underwater up to a height of 30 meters. Although not suitable for everyday use on dry land, the pouch is a good choice for water sports. The flexible pouch has a see-through window on the front and back, ideal for taking photos, videos, and facial calls (above water), seamlessly while swimming underwater, snorkeling, or maybe scuba diving.
The touch panel may not be 100% responsive as usual with the S21 Ultra as it is thick and should keep water out, although it is fine to press an on and off button and many basic functions such as on and off video recording. In short, it is a diving case. The lanyard is a great way to secure the case around your neck or forearm.
The bag clicks into place easily and can be removed. Available in a variety of color options, this option is a bargain price for the protection it provides. It keeps out water, snow, dust, sand, and dirt and is an ideal suitcase for an adventure or vacation. A great option in “Best Waterproof Cases for Samsung Galaxy S21 Ultra.”
