Overview
This guide explains why icons in the Dazos CRM mobile app may appear black or filled on iPhone and how to confirm and escalate the issue.
Symptom / Error
Icons in the Dazos CRM mobile app appear black or filled on iPhone, making the app difficult or nearly impossible to use. The same issue does not occur on Android devices or in the desktop web version of the CRM.
Cause
The Dazos CRM mobile app on iPhone uses Safari internally to render its interface. When display issues such as black icons appear on iPhone but not on Android, the root cause is typically a Safari browser rendering problem rather than an issue with the app installation itself.
Because Android uses a different internal browser engine, the same rendering problem will not affect Android users — which is why the issue appears isolated to iPhone.
Solution
The correct first step is to replicate the issue on an iPhone before escalating. This confirms whether the problem is a Safari rendering issue and provides engineering with the evidence needed to investigate.
Obtain a test iPhone — if possible, use a device running the same iOS version as the affected users.
Install the Dazos mobile app — download it from the App Store and log in with a test account.
Navigate to the affected screen — open the same area of the app where the black icons are reported.
Check whether the black icons appear — if they do, the issue is confirmed and ready to escalate.
Capture evidence — take a screenshot or short screen recording of the black icons, and note the iPhone model and iOS version.
Once the issue is confirmed on a test device, escalate to the Dazos engineering team with the evidence collected.
Escalation
Contact Dazos Support if:
You are able to replicate the black icons on a test iPhone.
The issue is affecting multiple iPhone users and making the app unusable.
You are unable to replicate the issue but affected users continue to report it.
When contacting support, provide:
A screenshot or screen recording showing the black icons.
The iPhone model and iOS version of the affected devices.
Confirmation of whether you were able to replicate the issue on a test device.
The specific screen or area of the app where the icons appear.
