# Info abap2UI5 ships the current frontend state with every roundtrip. Read it from `client->get( )` — no custom control, no extra event needed. The relevant sub-structures are `s_device`, `s_ui5`, `s_focus`, and `s_scroll`. ## Device For reading device information via `client->get( )-s_device`, see [Device Model](../model/device_model.md). ## UI5 For reading the runtime UI5 framework details via `client->get( )-s_ui5`, see [UI5 Versions](../../configuration/ui5_versions.md). ## Focus For reading the current focus via `client->get( )-s_focus`, see [Focus](../browser_interaction/focus.md). ## Scroll For reading scroll positions via `client->get( )-s_scroll`, see [Scrolling](../browser_interaction/scrolling.md). ## Working Samples Complete apps from the [sample catalog](https://github.com/abap2UI5/samples/blob/main/SAMPLES.md) that use what this page describes. Each is a single class — pull the repository with [abapGit](https://abapgit.org) and start it with `?app_start=`. | Sample | Class | |---|---| | Frontend Info: UI5 Version, Theme, OS, Browser | [`Z2UI5_CL_SMP_APP_122`](https://github.com/abap2UI5/samples/blob/main/src/01/z2ui5_cl_smp_app_122.clas.abap) | | Device Model: Phone, Tablet, Desktop (A) | [`Z2UI5_CL_SMP_APP_445`](https://github.com/abap2UI5/samples/blob/main/src/01/z2ui5_cl_smp_app_445.clas.abap) |
