Bug Fixes

11 fixes across device stability, payment & transaction flow, display, and protocol-specific behavior

Device Stability & Performance:

• Random Device Freeze on Idle Screen: Fixed an issue where Media 4 devices would randomly freeze with the idle screen displayed and the payment reader unresponsive, requiring a manual restart.
• Device Crash on Cash Payments: Fixed an issue where devices crashed when cash payments were used on MDB Level 1 protocol machines.
• Device Crash with Portuguese (Brazil)certain selected Languages: Fixed an issue where setting the LCD Primary Language to such as Portuguese (Brazil) caused device crashes.
• First Card Failure After Reset: Fixed an issue where the first card presented after a device reset would fail to read, displaying the “Activate your device” screen.
• Media 4 Mini Freeze in Marshall Multi Session Mode: Fixed an issue where VPOS Media 4 Mini devices in Marshall Multi Session mode froze on the idle brands screen after the second card presentation.

Payment & Transaction Flow:

• Card Not Accepted at $100+ Default Credit: Fixed an issue where devices would not accept cards when default credit was set to $100 or more. The device would double beep and not proceed with the transaction.
• Preauthorization Failure with Zero Decimal Currency: Fixed an issue where the preauthorization flow failed when currency decimal place was configured to 0.
• Device Freeze During PIN Entry Cancellation: Fixed an issue where canceling during PIN entry on contact EMV transactions caused the device to freeze on the “Authorizing” screen.

MDB Protocol-Specific:

• Incorrect Default Credit in MDB Level 1 Preselection Mode: Fixed an issue where devices reverted the default credit to 1000 (10.00) instead of the configured value in MDB Level 1 preselection mode.
• Random “Processing” Loop on MDB Level 1 Devices: Fixed an issue where MDB Level 1 devices randomly displayed “Processing” followed by “Select Product” without user interaction, then showed “Product not selected” and canceled.

Display & UI:

• Unnecessary Decimal Points for Whole Numbers: Fixed an issue where price displays showed unnecessary decimal points for whole numbers (e.g., “1111.0” instead of “1111”).
