Larix Broadcaster supports background streaming on Android by default, according to Softvelum’s FAQ. Start the stream while your Vivo phone is unlocked, confirm it is live, then lock the screen. If it stops, check Larix’s background and battery permissions: Android’s Restricted battery mode prevents background operation, and Vivo may apply additional model-specific controls.

Start the stream before locking your Vivo

  1. Open Larix Broadcaster and connect to your streaming destination while the phone is unlocked.
  2. Confirm the destination shows the stream as live before turning off the screen.
  3. Lock the screen and check the stream from another device if possible. Larix’s background-streaming behavior is documented by Softvelum, but an uninterrupted session is not guaranteed for every phone configuration.

Do not force-close Larix if you want it to keep streaming. Softvelum says Android background streaming is available by default until the user explicitly closes the app.

If the stream stops, check background restrictions

Review Android’s battery mode for Larix

Android provides Unrestricted, Optimized, and Restricted battery modes for apps. Optimized is the default; Restricted fully prevents background operation. Open your phone’s app battery settings, find Larix Broadcaster, and check its assigned mode. If it is Restricted, change it to a mode that permits background use. Android’s documentation explains these modes at Background optimization. Manufacturer software can impose additional limits.

Look for Vivo background-power controls

Vivo’s support index identifies a “High background power consumption” setting, but it does not give one menu path that applies to all phones. Settings labels and availability vary by model and software version. In Settings, search for Larix, battery, or background-use controls; if the relevant option is not shown, consult the manual or Vivo support for your exact device. See Vivo’s support index.

Yojaro 4Pack Silicone Suction Phone Case Mount, Silicon Adhesive Smartphones Stand Sticky, Hands-Free Phone Accessories Holder for Selfies and Videos (Black & White & Translucent & Light Pink)
  • 【Strong Adsorption】The inspiration of the silicone phone suction case comes from the adhesive force of the octopus. Each suction cup phone mount is 3.15 inches long and 2.17 inches wide, with 24 independent suction cups providing a stronger and more stable suction force, so you don't have to worry about your phone falling during use.
  • 【Back of Phone Suction Grip】Remove the adhesive film on the phone suction cup and stick it on the phone case. You can then fix the phone on any smooth surface, which is very convenient. (The phone suction cup cannot be removed and reused after being attached to the phone case. It is recommended to attach it to a regular phone case, not a valuable one.)
  • 【Widely Used】Our non-slip silicone phone sticky grip mount attaches to almost any flat phone case and make it compatible with common mobile phones such as iPhone and Android.You can shoot, watch videos or video calls in the kitchen, gym, dance studio, bathroom and other places.
  • 【Capture the Wonderful Picture】Whether you are a TikTok creator or just like to share videos and photos, this phone suction cup can help you hands-free capture wonderful videos and photos for sharing with friends.
  • 【Note】You can fix the phone suction cup on a smooth surface such as a mirror or glass. If necessary, wipe the suction cup with a damp cloth to obtain stronger suction. Before releasing your hand, make sure the phone is firmly fixed. (Not applicable to rough walls, wooden surfaces, and other uneven surfaces)

Test changes one at a time

  • Make sure Larix is not explicitly closed.
  • Temporarily allow Larix background use or relax its battery restriction, using the options available on your phone.
  • Start a fresh stream and lock the screen to check whether the change resolved the issue.

There is no single toggle that can be promised to fix background streaming on every Vivo. The phone model, Android release, and Funtouch OS or OriginOS version matter.

Separate app restrictions from battery or signal problems

Live streaming, mobile-data use, background activity, and a weak signal can all contribute to higher power consumption. Vivo also notes that weak signal and long live-streaming sessions can increase battery use; its guidance is available at Vivo China support. If the phone stays online but its battery is draining, a compatible power bank may extend the session. It will not prevent Android or Vivo software from stopping a restricted app.

Apple EarPods Headphones with USB-C Plug, Wired Ear Buds with Built-in Remote to Control Music, Phone Calls, and Volume
  • SUPERIOR COMFORT — Unlike traditional circular ear buds, the design of EarPods is defined by the geometry of the ear. Which makes them more comfortable for more people than any other ear bud–style headphones.
  • HIGH-QUALITY AUDIO — The speakers inside EarPods have been engineered to maximize sound output and minimize sound loss, which means you get high-quality audio.
  • BUILT-IN REMOTE — EarPods with USB-C plug also include a built-in remote that lets you adjust the volume, control the playback of music and video, and answer or end calls with a pinch of the cord.
  • COMPATIBILITY — Works with all devices that have a USB-C port.
  • INTEGRATED MICROPHONE — A built-in microphone precisely captures your voice while you’re on the phone, taking a FaceTime call, or summoning Siri — so you’re always heard loud and clear.

Troubleshoot a stream that still ends

What you notice What to check
The stream ends soon after you lock the screen. Check that Larix is not Restricted, review Vivo’s app background or battery controls, and avoid explicitly closing the app.
The stream runs but the phone loses charge quickly. Check signal strength and power-saving behavior. A compatible power bank may help with battery capacity, but not background restrictions.
You cannot find a setting mentioned in a guide. Vivo settings vary by model and software version. Search Settings for Larix, battery, or background use, then check your model’s manual or contact Vivo support.
The stream remains unreliable after changing permissions. Test continuity after each change. When asking Vivo or Larix support for help, include the phone model, Android release, and Funtouch OS or OriginOS version.
