The Best Diagnostic Software to Test Cell Phones

Whether you deal in cell phone repairs only or sell refurbished phones too, investing in mobile diagnostic software is a very good idea to increase footfall for your repair shop.

Life without a Diagnostic Software

Without diagnostic software, for every phone that comes in with a repair or refurbishment request, you have to follow an extensive manual process to determine the possible faults. Manual processes have the following drawbacks:

  • Slow and unsatisfactory diagnostic process
  • Inaccurate and incomplete diagnoses based on guesswork
  • Unknown eligibilities, validation requirements, Terms & Conditions
  • Skipping Data Protection SOPs and Legalities
  • Inefficient process of erasing phone data for refurbishment

Advantages of Having a Diagnostic Software

Having diagnostic software can really help address all the manual process drawbacks.

With repairs, knowing exactly what’s wrong with a device allows you to inform your customers about the real condition of their devices and helps you follow the best repair practices.

Refurbished phones, on the other hand, are usually bought in batches. Scanning their barcode to add them to your point of sale software might be easy but manually checking each takes a very long time and is much less efficient as well. So, using a diagnostic tool makes more sense.

If you offer trade-ins, having comprehensive diagnostic software for cell phones can save you from buying a phone at a high price. You will also find out how much work needs to be done on each device, if any, and price it accordingly.

RepairDesk has a dedicated section for trade-ins where you can easily add the cost of the repair of a trade-in if any and price them accordingly. 

This blog covers the five most recommended software for you to choose from so you can make the best decisions for your business. But first, let’s identify the common issues in cell phone repair orders.

Common Issues In Cell Phone Repair Diagnosis

When a phone comes in for repair, a visual examination helps identify physical repair issues but running a quick diagnostic check can identify everything that is wrong with the phone from the inside. The more information you have about the faults in the device, the smoother your following workflow will be.

On the hardware side, a broken screen is one of the most common repairs, which requires a screen replacement.

On the software side, doing a diagnostic check has many benefits, such as providing accurate quotes to customers, offering more comprehensive repair services, recording a device’s condition for legal purposes, etc. Filling out the pre-repair checklist – essentially a checklist for your diagnostics – and sharing it with the client helps bring everyone on the same page.

Some of the most common repair issues include:

  • Screen issues such as dead pixels
  • Battery charging and drainage issues
  • IMEI issues and functionality errors 
  • Screen and Keypad touch sensor problems
  • Audio and microphone functioning troubles
  • Front or back camera malfunction
  • Software update or re-installation difficulties
  • Bluetooth, wifi and other connectivity hitches

When identified, all these issues can be recorded if you have a POS system that offers a check list feature. RepairDesk offers an in-built checklist that you can use to keep all repair ticket records in one place and improve your job tracking system. It also has an inventory management feature which makes keeping track of your refurbished phone stock easy and simple.

Use the Built-in Diagnostic Tool in your Phone

Oftentimes, you’ll be lucky because the phone that comes in for repair will have in-built software for running diagnostics. Modern phones these days can help you run your diagnostics before you’ve fired up any specific software or put it under a magnifier. When these phones are manufactured and produced, a particular part of their software is reserved for diagnostic tests for repair purposes. This makes it easier for manufacturers and officially-licensed repair technicians to work on the repair of these phones since the self-check-up software can help them diagnose their issues easily.

While Apple is notorious for making it virtually impossible for users to perform self-check-ups on their phones, Xiaomi and other Android cell phone manufacturers come with their own hidden diagnostic apps. You can activate the test app by typing certain codes:


You can check battery level and performance by going into Settings > Battery


  • *#0*# for hidden diagnostics menu
  • *#*#4636#*#* for usage information menu

Dialing the codes and finding the exact information you are looking for can be a little tricky. Moreover, the information and tests provided by these built-in diagnostic tools are quite basic. They can analyze the general health of the phone and run a few basic tests, but they will not be helpful if you need a detailed diagnosis.

To get a detailed diagnosis, opt for a purpose built software. Here are the most popular ones for 2023.

The Best Diagnostic Software for Cell Phone Repair Shops
