Samsung SolarCell Remote 2024 vs Sony RMF-TX621U Voice Remote

These are not interchangeable: each remote only controls its own brand's TVs. The Samsung SolarCell is the better pick for Samsung owners who want a remote that never needs disposable batteries, with solar and USB-C charging and a slim design. The Sony RMF-TX621U is the better pick for Sony Bravia and XR owners who watch in the dark, thanks to backlit keys and a metal front. Owners of both report the remotes work as described; the main complaints are about sellers and shipping, not the remotes themselves.

  • Choose the Samsung SolarCell Remote if you own a 2022 or newer Samsung Smart TV and want a rechargeable remote with voice control and no battery swaps.
  • Choose the Sony RMF-TX621U if you own a Sony Bravia or XR TV and want backlit buttons and a metal-front remote for dark-room viewing.

Questions and answers

Will the Samsung SolarCell Remote work with a Sony TV?
No. It pairs only with Samsung TVs, mainly 2022 and newer Smart TVs. For a Sony set, buy the Sony remote.
Will the Sony RMF-TX621U work with a Samsung TV?
No. It is made for Sony Bravia and XR series TVs. It will not control a Samsung TV.
Which remote is better for watching in a dark room?
The Sony. Its buttons are backlit, so you can see them without turning on a light. The Samsung remote has no backlight.
Which one lasts longer without maintenance?
The Samsung. Its solar panel and USB-C charging keep the built-in battery topped up, so you never buy batteries. The Sony needs fresh AAA batteries periodically.
Is the Sony remote worth stepping up to over a basic Sony remote?
Yes if you want backlit keys, a metal front and voice control in one remote. A basic Sony remote is cheaper but lacks the backlight and the metal build.
Do either of these need programming?
The Sony needs no programming on supported Sony TVs. The Samsung pairs over Bluetooth, which takes a minute or two on a compatible Samsung TV.
