### 5/5 — Gute App mit noch besserem Support

*2026-08-03*

Habe die App für mein GR iiix. Am Anfang habe ich die Verbindung leider nicht hinbekommen. Der Support hat mir per Mail ausgesprochen schnell und kompetent helfen können. So wurde mein Fehler beim verbinden schnell gelöst und alles funktioniert einwandfrei.

### 5/5 — 好用

*2026-07-21*

比官方的好用，链接稳定，快速。

### 1/5 — Not working

*2026-01-16*

I want my money back….

**Developer response:** Please read the User Guide carefully, especially the following:
1. Whether the application has been granted the necessary permissions.
2. Whether the Wi-Fi SSID and password have been entered correctly.
Thank you.

If you need a refund, please apply through the App Store.

### 2/5 — 问题反馈

*2025-10-30*

不好，用了很久后无法下载，店里启动暂停都没有反应。点击问题反馈。需要邮箱登陆，显示找不到我的邮箱，就是说找不到客服^_^

**Developer response:** 你好，你可以用自己的邮箱发邮件到developer@yaoyouguang.net，我们会提供技术支持。

### 1/5 — 説明がわかりにい上に繋がらない

*2025-08-26*

繋がらないです。お金返してください

**Developer response:** こんにちは、返金が必要な場合は App Store で手続きをしてください。

### 5/5 — 希望能开发鸿蒙版

*2025-08-17*

希望能开发鸿蒙版本

### 5/5 — 好用，但是照片数量显示能不能修补一下

*2025-06-23*

内存卡内照片超过3000之后就没办法用了，刚超过3000的时候为了传照片还删一下，但是现在远远超过了，现在基本上用不了了！希望可以尽快解决这个问题🙋

**Developer response:** 你好，最新版本已经修复照片总数超过3000张时，最新照片可能不展示的问题。更新到最新版本即可。

### 2/5 — Okay, but crucial detail is missing

*2025-06-09*

The App works okay, but RAW+ photos are not added to the Photos App as a RAW+JPEG pair, instead they are imported as two separate pictures.

So I‘ll have to keep using my SD card adapter anyway, but if this feature is added, this turns into a 5 star app to me

### 1/5 — 환불요청 안되네요

*2025-03-03*

환불요청합니다 연결 안되네요 이걸 돈주고 사라거 하다니 아무튼
안내에 있는 내용 읽어봣고 메모리카드
포맷까지 햇는게 안됩니다 실망

**Developer response:** “사용자 가이드”에서 자주 묻는 질문에 대한 설명을 자세히 읽어 주세요.
그럼에도 해결되지 않으면, 앱 내 문제 피드백을 통해 기술 지원팀에 문의해 주세요.
환불이 필요한 경우, App Store에 신청하시면 됩니다.

### 5/5 — 活人app

*2025-02-07*

因为连不上wifi在app问题反馈处写了自己遇到的问题，app开发就会联系你，一起研究和找问题并提出解决办法，照片传输也非常流畅。理光官方app平时是够用的，但偶尔会冒出来照片黑屏、传输卡滞等问题且反馈无门。所以这个软件还是很值得入的。

**Developer response:** 很高兴你能喜欢我们的App。😄
遇到问题请查看《使用指南》，还无法解决通过App内意见反馈联系我们获得技术支持。
