Samsung unveiled its crop of new mobile devices Wednesday, including two versions of the Note 20 smartphone, an updated foldable device, two tablets and a watch.

Why it matters: The new devices aim to give Samsung an early start at the second half of the year, with products aimed at parents buying fresh gear for the back-to-homeschool season.

Details:

• The Note 20 Ultra, which starts at $1299, is Samsung's most powerful smartphone, featuring a 6.9-inch display, new laser autofocus sensor and support for both 5G wireless networks and ultra-wideband technology for easier sharing to nearby devices.
• The standard Note 20 starts at $999 and has a 6.7-inch display, and has lower-resolution wide-angle and telephoto lenses than the Ultra version.
• The Galaxy Tab S7 and Tab S7+ tablets aim to take on the iPad Pro at the high end of the tablet market. A 5G-equipped version is coming to AT&T this fall.
• Galaxy Watch 3 will come in two sizes and in both bluetooth-only and cellular options, with prices ranging from $399 to $479, depending on options.
• Galaxy Buds Live are bean-shaped wireless earbuds that come in colors to match the new Galaxy Note devices and are priced at $169.

What's next: Preorders for the Note 20 and Note 20 Ultra begin Aug 6, with the devices available starting August 21. Samsung and the major U.S. wireless carriers are having a variety of promotions, including a "buy one, get one" deal from Verizon and AT&T's offer of up to $1,000 off the Galaxy Note with a qualifying trade-in and 30-month commitment.
