Is this a startup idea?

Not directly. These are complaints about a product or service people already use — the fix belongs first to that provider.

Questions about this idea

Is Mobile App Plagued by Technical Failures 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?
8 different people described it independently, in 8 mentions, the earliest from 31 Jul 2026 and the most recent from 02 Nov 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. 1 people raised it in the last 30 days and 1 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.

    Zalo gặp lỗi kết nối ví và không sao lưu được dữ liệu khiến 8 người dùng ở đây cảm thấy cực kỳ bất tiện khi cần xem lại tin nhắn cũ. Bọn mình nhận thấy tình trạng tải trang chậm hoặc lỗi mã Meta cũng đang xảy ra khá thường xuyên. Mọi người thường mất bao lâu để tự sửa được các lỗi này và thao tác cụ thể nào đã giúp ứng dụng hoạt động bình thường trở lại?
