How to read a Samsung model number
Hover over or tap each part of the code.
Year letter (all markets)
J2015 (Tizen 2.3)K2016 (Tizen 2.4)M2017 (Tizen 3.0)N2018 (Tizen 4.0)R2019 (Tizen 5.0)T2020 (Tizen 5.5)A2021 (Tizen 6.0)B2022 (Tizen 6.5)C2023 (Tizen 7.0)D2024 (Tizen 8.0)F2025 (Tizen 9.0)H2026 (Tizen 10.0)
Samsung skips some letters. 2017 and 2018 QLED codes put the year in a different place (Q7F, Q9FN): there, F and FN are part of the series name, not 2025. Older 2012–2014 sets used E, F and H right after the screen size (UN46H6203); those run Samsung's Legacy Platform.
US QLED, Neo QLED, OLED and The Frame (2019 and later)
QNUS prefix for QLED, Neo QLED, OLED and The Frame65Screen size in inchesQN90Series. QN is Neo QLED, Q is QLED (Q80), S is OLED (S90), LS03 is The FrameDYear letter: D is 2024
The full US code adds a factory suffix such as AFXZA (QN65QN90DAFXZA). The suffix can be ignored when checking compatibility. The Frame used the UN prefix in 2017 and 2018 (UN55LS003, UN55LS03N).
US Crystal UHD and UHD (2016–2024)

From 2025, Samsung's series names put the year letter at the end, as on QLED codes (U8000F is the 2025 version of the 8000 series).

Troubleshooting
Most problems come from the network or one TV setting. Start at the top.
The TV never shows the Allow prompt
- Check that your iPhone and the TV are on the same Wi-Fi network, not a guest network.
- Open Device Connect Manager and make sure Access Notification is not turned off. 2021: Settings > General > External Device Manager. 2022–2024: Settings > All Settings > Connection > External Device Manager. 2025 and later: Settings > All Settings > Connections.
- If your iPhone is in the Device List as Denied, set it to Allow or delete it, then connect again.
The app can't turn the TV on
- Turn on Power On with Mobile in the network Expert Settings (see the setup steps for your year).
- Turn the TV off with the remote, not at the wall. A TV that was unplugged can't be woken over the network.
- If it still doesn't wake, turn the TV on with the remote. The rest of the controls will still work once it's on.
The TV never shows the Allow prompt
- Check that your iPhone and the TV are on the same Wi-Fi network, not a guest network.
- Open Device Connect Manager on the TV and check that Access Notification is not turned off. The path depends on the year: Settings > General > External Device Manager (2021), Settings > All Settings > Connection > External Device Manager (2022–2024), or Settings > All Settings > Connections (2025 and later).
- Look in the Device List. If your iPhone is listed as Denied, change it to Allow or delete it, then connect again.
The app can't turn the TV on
- Turn on Power On with Mobile in the network Expert Settings. 2017–2021: Settings > General > Network > Expert Settings. 2022 and later: Settings > All Settings > Connection (or Connections) > Network > Expert Settings.
- Turn the TV off with the remote, not at the wall. A TV that has been unplugged or switched off at the wall can't be woken over the network.
- Keep the TV on the same network as your iPhone. Some routers stop passing wake-up traffic to devices in standby after a while.
The TV turns itself on
- Samsung's support pages say network devices can turn the TV on when Power On with Mobile is on. If you don't need to wake the TV from your phone, turn Power On with Mobile off.
How to use your iPhone as a Samsung Crystal UHD TV remote
- Join the same Wi-FiConnect your iPhone and the TV to the same home Wi-Fi network. Guest networks often keep devices apart.
- Pick your TV in the appOpen Simple TV Remote and choose your TV from the list. The free check runs on your own TV before you pay anything.
- Choose Allow on the TVThe TV asks once whether to allow your iPhone. Choose Allow with your Samsung remote.
- Let your iPhone turn the TV onTurn on Power On with Mobile in the network Expert Settings: Settings > General > Network on 2017–2021 models, Settings > All Settings > Connection > Network on 2022–2024 models, and Connections instead of Connection from 2025. This is optional and only works from standby.
Questions
Is there a Samsung Crystal UHD TV remote app for iPhone?
Yes. Simple TV Remote is a Samsung Crystal UHD TV remote app for iPhone that works with Samsung Crystal UHD TV sets running Samsung Tizen. It pairs over your home Wi-Fi and sends real commands in a free check, so you know it works on your exact TV before you pay $5.99, once.
Is a Crystal UHD remote different from a QLED remote?
The setup is the same. Crystal UHD is Samsung's standard 4K range and QLED adds a quantum-dot layer, but both run the same Tizen software, so the menus match for TVs from the same year. That also means Simple TV Remote works the same way on both.
How do I pair a Samsung Crystal UHD remote?
Stand within about 1 foot of the TV, point the remote at it, and hold Return and Play/Pause together for at least 5 seconds. Let go when the TV says the remote is connected. If it won't pair, unplug the TV for 30 seconds and try again.
How do I reset a Samsung Crystal UHD remote?
On a SolarCell remote (2021 and later TVs), hold Return and Enter, the center of the navigation pad, for 10 seconds. On a battery remote, take the batteries out and hold Power for 8 seconds. Then pair it again with Return and Play/Pause.
How do I turn on a Samsung Crystal UHD TV without the remote?
Press the Controller button on the TV. On many Samsung models it's under the bottom center or bottom right of the screen, but the spot and shape vary by model. Once the TV is on, press it once for a small menu with power, volume, channel and source.
Which Crystal UHD and UHD TVs work?
Samsung 4K TVs from 2016 onward work. Before 2020 the same tier was called 4K UHD: KU in 2016, MU 2017, NU 2018 and RU 2019. On 2016–2024 codes the letter after the size is the year, so UN55CU8000 is a 2023 TV. From 2025 the letter moves to the end (U8000F).
How do I let my iPhone turn on my Crystal UHD TV?
Turn on Power On with Mobile in the network Expert Settings. On 2017–2021 models it's Settings > General > Network > Expert Settings. On 2022–2024 models it's Settings > All Settings > Connection > Network > Expert Settings. From 2025 it's Settings > All Settings > Connections > Network > Expert Settings. We haven't confirmed where the setting is on 2016 models, so on those turn the TV on with its button or remote first.
I pressed Deny on my Crystal UHD TV. How do I fix it?
Open Device Connect Manager and set your iPhone to Allow, or delete it so the TV asks again. On 2021 models it's in Settings > General > External Device Manager. On 2022–2024 models it's Settings > All Settings > Connection > External Device Manager. From 2025 it's Settings > All Settings > Connections > Device Connect Manager.
Is Crystal UHD the same as QLED?
Crystal UHD is Samsung's standard 4K LED range; QLED adds a quantum-dot layer. Both run Tizen, so the setup steps are the same for TVs from the same year.
How do I tell which year my TV is?
On 2016–2024 codes, read the letter after the size: K 2016, M 2017, N 2018, R 2019, T 2020, A 2021, B 2022, C 2023, D 2024. From 2025 it's the last letter (U8000F).
Can my iPhone turn the TV on?
Only from standby and only with Power On with Mobile turned on in the network Expert Settings. We haven't confirmed the setting on 2016 models.
Can I type into apps from my iPhone?
We don't know yet. Text input is marked unknown for Samsung TVs until we've tested it.
About these TVs
Crystal UHD is Samsung's main 4K LED range from 2020 onward. Before that, the same tier was sold as 4K UHD TV: KU series in 2016, MU in 2017, NU in 2018 and RU in 2019.
On 2016–2024 codes the year letter comes right after the screen size: UN55CU8000 is a 55-inch 2023 CU8000, and UE55TU7100KXXU is a UK 2020 TU7100. From 2025 the letter moves to the end of the series (U8000F).
Every model in this range is a Tizen smart TV. The menus match Samsung's QLED TVs from the same year.
