Zalo: Incoming calls and messages do not notify
Users frequently experience issues with missed calls and messages on the app, often requiring them to reopen the application to respond. This results in significant frustration due to the unreliability of notifications and communication features.
13 different people have complained about this since 30 Jul 2026, most recently on 30 Oct 2026. 3 of them in the last 30 days.
- “Hay bị lỗi mặc dù có mạng nhưng đôi khi người khác gọi cho mình không được cần khắc phục”
- “Thường xuyên bị lỗi cuộc gọi và tin nhắn.”
- “Cuộc gọi voice hay video call đều uêus và đứng lỗi quá trời lỗi”

Questions about this idea
- Is Incoming calls and messages do not notify a startup idea?
- Not directly. These are complaints about a product or service people already use, and the fix belongs first to that provider. The page shows what is frustrating users and how badly — not an open market to start a company in.
- How many people have this problem?
- 13 different people described it independently, in 13 mentions, the earliest from 30 Jul 2026 and the most recent from 30 Oct 2026. The quotes, with dates and links to the originals, are in the Evidence section.
- Is this problem getting worse?
- Status: steady — no change the counts can show. 3 people raised it in the last 30 days and 3 in the 30 days before; the status compares its share of everything collected from the same source, so collecting more or less cannot create a trend.
