Troubleshooting
Google/Android
The inFlow Smartphone Scanner uses the Android operating system. For general questions and articles related to how to use your new Android device, please visit: https://support.google.com/android/
I can’t find the inFlow app or the Stockroom app
The inFlow and Stockroom app is available from the Google Play Store. After setting up the Smartphone Scanner, you need to login Google Play with a valid Google account to download and install the apps.
There is a bracket beside the back POGO pins obstructing putting on the Hand Grip, how do I remove it?
The bracket comes handy if you want to put on a strap (not included). This bracket can be removed from the device by using a T5/T6 torx bit to unscrew the screws on the sides of the bracket.
I only want the last 10 digits of scanned barcodes, is that possible?
There can be multiple ways to achieve this. Here are the steps using the Scanner app already built in.
- Go to Scanner app
- tap (…) ellipsis > Basic Settings > Advanced Data Formatting
- if there is already a rule under Rules, tap and hold on it then delete it
- tap (…) ellipsis > New rule, call it anything you want like “Rule 1”
- tap the rule line > Configuration Operation
- tap (…) ellipsis > New Operating > select Skip back from the dropdown
- tap (…) ellipsis > New Operating > select Move to from the dropdown
- reorder the sequence so its Move to, then Skip back, then Send Remains
- tap Move to, tap String, input 10000
- go back, tap Skip back, tap Characters Number, input 10
- go back to the Rule screen and make sure Enable is checked
I can’t access data from my T-mobile sim card
The Smartphone Scanner lets you use sim cards with wireless plans. For T-mobile customers, activate the sim card on a T-mobile device with a wireless plan first. Once that’s done, you can transfer the sim card to the Smartphone Scanner and you’ll have access to your data.
Which Smartphone Scanner do I have?
The inFlow Smartphone Scanners have continued to improve over the years. Most of the improvements from the two Smartphone Scanners are internal, but a quick way to know which scanner you’re using is by looking at the camera.
The Smartphone Scanner 3 has a single camera lens, whereas the Smartphone Scanner 2 has two lenses.
