Troubleshooting Explosion Proof Smartphones: Quick Fixes (2026)

Introduction:

Explosion-proof smartphones are critical tools for workers operating in high-risk environments like oil refineries, chemical plants, and mining sites. These devices are specifically designed and certified (e.g., ATEX, ATEX) to function safely in hazardous locations where flammable gases or dust may be present. However, like all electronics, they can sometimes face technical issues.

In this guide, we’ll walk you through the most common problems and solutions related to explosion-proof smartphone troubleshooting. Whether you’re using models like the Ex 72 Plus, Ex 101 Ultra, or Ex 100 Pro, these tips will help you get your device back on track safely and efficiently.

What Makes Explosion-Proof Smartphones Unique?

Before diving into troubleshooting, it’s essential to understand why explosion-proof smartphones differ from regular mobile devices.

These smartphones are enclosed in sealed, rugged casings that prevent internal sparks or heat from interacting with external explosive materials. They are built to operate in Zone 1 and Zone 2 hazardous environments, meaning any repair or reset must respect their safety certifications.

Because of this, troubleshooting explosion-proof smartphones involves more caution and specific protocols compared to consumer devices.

Common Explosion-Proof Smartphone Issues and Solutions

1. Device Not Charging in the Field

Possible Cause:

• Blocked or damaged charging port

• Use of a non-certified charger

• Extreme temperature or humidity

Solution:

• Always use the original, ATEX-approved charging cable and dock

• Clean the charging port gently with a non-metallic brush

• Avoid charging in areas where explosive atmospheres may occur—even if the device is certified

2. Touchscreen Not Responding (Especially with Gloves)

Possible Cause:

• Thick industrial gloves

• Moisture or chemical residue on screen

• Software lag or freeze

Solution:

• Use glove-compatible mode if your device supports it (Ex 72 Plus and Ex 101 Ultra)

• Clean the screen with a dry, non-static microfiber cloth

• Restart the device if it becomes unresponsive; hold power + volume button for 10 seconds

3. Bluetooth or Wi-Fi Not Connecting

Possible Cause:

• Signal interference in industrial areas

• Outdated firmware

• Device software glitch

Solution:

• Move away from metal enclosures or machinery when troubleshooting

• Restart Bluetooth or Wi-Fi connection

• Ensure firmware is up to date via a secure, certified network

• If issue persists, contact technical support

4. Camera Not Opening or Freezing

Possible Cause:

• Device settings conflict (especially if multiple apps use the camera)

• Memory overload

• Hardware malfunction

Solution:

• Clear camera cache via settings

• Restart the device

• Delete unused media files to free up space

• If hardware issue is suspected, submit the device for certified repair (avoid opening it yourself)

5. App Crashes or System Lag

Possible Cause:

• Too many background apps

• Incompatible third-party software

• Full storage or outdated OS

Solution:

• Remove unused apps

• Use only apps recommended by the manufacturer

• Regularly back up and clean internal memory

• Contact the support team for safe OS update instructions

Preventive Maintenance for Explosion-Proof Smartphones

• Keep the exterior clean and free from oil, dust, and corrosive chemicals

• Avoid software modifications (no rooting or jailbreaking)

• Do not open the casing under any circumstance

• Check certification seals regularly to ensure no tampering or damage

• Store devices in a dry, cool, non-hazardous environment when not in use

When to Contact Professional Support

If you’ve tried all the safe troubleshooting steps and the issue persists, it’s time to reach out to the manufacturer or your authorized service provider. Attempting to open or repair the device yourself may void the certification and pose serious safety risks.

At Infinity-Ex, certified support teams can help you with:

• Hardware diagnostics

• Certified repairs

• Warranty claims

• Device replacements

Frequently Asked Questions (FAQs)

Q1: Can I charge my explosion-proof phone in Zone 1?
A: No. Even though the phone is certified, charging should only be done in safe areas.

Q2: My device is overheating. Is that normal?
A: Mild heating under heavy use is okay, but if it’s excessive, turn off the device and contact support.

Q3: Which gloves work best with the Ex 101 Ultra?
A: Thin, conductive gloves or ATEX-approved gloves designed for touchscreen use.

Q4: What’s the safe way to update apps?
A: Only use the official app store or company-approved update channels, while connected to a secure network outside of hazardous zones.

Conclusion: Reliable Troubleshooting for Explosion-Proof Smartphones

Troubleshooting explosion-proof smartphones requires care, attention, and strict adherence to safety standards. These devices are essential in hazardous workplaces, and handling them properly ensures both functionality and worker safety.

If you’re using ATEX-certified models from Infinity‑Ex, always follow the manufacturer’s support guidelines and never attempt repairs on your own. A well-maintained explosion-proof smartphone can serve as a powerful asset in critical field operations—keeping teams connected, compliant, and safe.

Industrial Applications & Real-World Use Cases

In hazardous industrial environments such as oil refineries, petrochemical plants, offshore platforms, and mining operations, reliable communication is a critical safety requirement. Workers in Zone 1 and Zone 21 classified areas face constant exposure to flammable gases, vapors, and combustible dust. Any electronic device used must be intrinsically safe to prevent ignition.

Oil & Gas Operations

Field engineers on drilling rigs, well pads, and production platforms rely on ATEX certified devices for work order management, real-time communication with control rooms, digital permit-to-work systems, and photographic documentation. Our devices are deployed across ADNOC, Saudi Aramco, KOC, KNPC, ONGC, Petrobras, and Shell facilities worldwide.

Refinery & Petrochemical Safety

Process safety management requires continuous communication between operators, maintenance technicians, and HSE personnel. ATEX phones enable instant push-to-talk during turnarounds, emergency responses, and inspection rounds. Explosion-proof tablets allow viewing P&IDs and digital checklists in the field.

Offshore Platform Operations

Offshore environments present salt spray corrosion, extreme weather, and limited charging infrastructure. Our IP68-rated devices withstand these conditions while maintaining Zone 1 certification for crane coordination, emergency mustering, and helicopter manifesting.

Safety Compliance Standards

• ATEX Directive 2014/34/EU — European explosive atmospheres standard
• Ex ia IIC T4 Gb — Zone 1 intrinsic safety for gas groups
• Ex ia IIIC T135°C Db — Zone 21 dust protection
• IP68 — Dust and water protection
• MIL-STD-810H — Military-grade durability

Selecting the Right Device for Your Operation

Choosing the correct explosion-proof device depends on your specific operational requirements, environmental conditions, and workflow needs. Here are the key factors to consider when evaluating intrinsically safe communication equipment for your facility:

For Field Operators and Technicians

Personnel performing daily rounds, equipment inspections, and maintenance tasks benefit from compact phones with long battery life and rugged construction. The EX72 Plus delivers excellent balance between size, durability, and Zone 1 certified functionality for hands-on field work.

For Engineers and Supervisors

Professionals who need to reference drawings, access CMMS systems, review data trends, and manage digital permits require larger displays and more processing power. The EX 101 Ultra and INFINITY EX 100 PRO provide the performance needed for these demanding tasks while maintaining full ATEX certification.

For Tablet-Based Workflows

Operations transitioning to digital permit-to-work, electronic logbooks, or tablet-based inspection systems need larger screen formats. The TL110 5G Tablet provides a desktop-class experience in a Zone 1 rated package, ideal for control room extensions, field engineering, and supervisor walkdowns.

Key Selection Criteria

• Zone classification of your operating environment (Zone 1 gas and/or Zone 21 dust)
• Temperature range at your facility (our devices operate from minus 20 to plus 60 degrees Celsius)
• Battery duration needed for your shift length (8, 12, or 16 hour shifts)
• Application requirements such as SAP, push-to-talk, camera quality, or GPS accuracy
• Network compatibility with your facility communications infrastructure
