Recently purchased above phone. SmartView does not effectively stream content from device to LG UHD 4K TV. Audio is glitchy and full of static, gallery casting displays Reconnecting Recommended error message, and gaming behaves the same way. No issues streaming to same TV with Samsung S8, Samsung Galaxy Tab5e or G Pad 5 10.1 FHD.
After support troubleshooting, tech declared device defective. Received replacement device today from cellular provider and exact issue is replicated.
Downloaded Chromecast from Google Playstore and same issue exists.
Appears a software issue / bug report needs to be submitted and a software update provided to resolve issue.
