How do I fix the memory card error on my button phone?

What causes the memory card error?

The memory card error on button phones is usually caused by one of a few issues:

  • Corrupted memory card – If the memory card has become corrupted due to damage, formatting issues, or file system errors, it may cause the phone to show the memory card error.
  • Improperly inserted memory card – If the memory card is not fully inserted into the phone, is inserted upside down, or the cover/door is not fully closed, it can cause connection issues.
  • Incompatible memory card – Using a memory card that is not compatible with the phone can result in connectivity issues. Make sure the card matches the specifications for your device.
  • Damaged memory card slot – If the phone’s memory card slot is damaged due to drops, moisture, dirt, etc, it may not be able to properly read memory cards.
  • Software issue – Sometimes a bug or glitch in the phone’s software can cause it to incorrectly detect issues with the memory card.

So in summary, the memory card error is usually due to some kind of physical issue with the card itself, the way it was inserted, or damage to the phone’s card slot. Software problems can also be a cause in some cases.

How to fix the memory card error

If you are seeing a memory card error on your button phone, here are some steps you can take to try and resolve it:

1. Remove and reinsert the memory card

The first step is to remove the memory card and then reinsert it to ensure it is properly seated in the slot. Here is how to do this:

  • Turn the phone off and remove the back cover.
  • Locate the memory card slot and gently press on the card to release it from the locked position.
  • Carefully slide the memory card out of the slot.
  • Inspect the ends of the memory card for any dirt, dust, or debris. Clean with a soft cloth if needed.
  • Reinsert the memory card with the gold contacts facing downwards and the notch on the correct side.
  • Gently push the card into the slot until it clicks and locks into place.
  • Replace the back cover and turn the phone back on.

Reseating the memory card will often fix connection issues caused by an improper insertion.

2. Inspect the memory card slot

If reinserting the card does not work, visually inspect the memory card slot inside the phone. Look for any signs of damage such as:

  • Pins are bent or broken
  • Slot has cracks or pieces broken off
  • Debris, dirt or dust built up in slot
  • Moisture or liquid damage

Any visible damage to the slot can prevent proper contact with the memory card. If you see damage, the phone may need professional repair.

Also check to make sure the slot is clear of any obstruction – blow compressed air into the slot to dislodge any dust, lint, etc. Debris buildup can prevent the card from seating properly.

3. Try a different memory card

If your card slot appears undamaged, try testing with a different memory card. Use a card that you know is working properly in other devices.

If the phone recognizes the new card without issue, the problem is likely with your original memory card and not the phone’s card slot. You will need to replace the damaged or corrupted card.

However, if the memory card error persists even with a new card, then the issue lies with the phone’s card reader. You will need to get the phone professionally inspected and repaired.

4. Reset your phone

Resetting the phone can clear out any software bugs that may be causing incompatibility issues with the memory card.

Here are the steps to reset:

  • Back up any data and contacts you want to keep before resetting.
  • From the idle screen, open the phone’s Settings menu.
  • Select ‘Backup & Reset’ or ‘Reset’ options.
  • Choose ‘Factory Data Reset’ – this will erase all data and restore defaults.
  • Follow the prompts to confirm the reset and power cycle the device.

After resetting your phone, try reinserting your memory card. This may resolve any software glitches that were previously giving the error.

5. Reformat the memory card

If you’ve verified the card slot is not damaged, try reformatting your memory card. This erases all data but can fix file system errors and corruption.

To reformat:

  • Copy any files and data you want to keep onto another device before reformatting.
  • On a computer, insert the memory card into a card reader or card slot.
  • Open My Computer/This PC and right click on the drive letter of your memory card.
  • Select ‘Format’ in the pop-up menu.
  • Choose FAT32 or exFAT file system.
  • Check the ‘Quick Format’ box and start the process.

Reformatting will erase and reconfigure the card to work properly again. Just make sure you’ve backed up your data first.

6. Clean the memory card’s contacts

Dirty or greasy residue on the gold contacts of the memory card can cause connection problems.

Carefully clean the contacts using a soft toothbrush and rubbing alcohol. Gently brush in one direction only.

Allow contacts to fully dry before reinserting the card. This cleaning can removebuilt up grime and improve connectivity.

Getting professional phone repair

If you’ve tried all of these troubleshooting steps and the memory card error persists, your phone will likely need professional repair. Here are a few options:

  • Manufacturer repair – Check if your phone is still within warranty with the manufacturer. They can repair or replace damaged components.
  • Cell phone repair shops – Local repair stores can diagnose issues and offer same-day service in many cases. Prices vary.
  • Carrier repair – Mobile carriers often have phone repair services and may be covered under your insurance.
  • Mail-in services – Companies like iCracked accept mailed devices, provide free diagnoses, and reasonable repair rates.

For severe physical damage, getting the memory card reader replaced by a professional may be your only option. If the issue stemmed from a software glitch, a technician can also provide a fresh install of the OS.

Data recovery from a damaged memory card

If important files and data on your memory card have become inaccessible, you may need professional data recovery. Here are some tips:

  • Stop using the card immediately. Any new activity could overwrite your files.
  • Don’t attempt DIY recovery using disk utilities – this often worsens the damage.
  • Find a reputable data recovery company. Look for positive reviews and endorsements.
  • Expect a diagnostic evaluation fee upfront. The recovery cost depends on the card’s condition.
  • Data recovery has good success rates as long as you don’t damage the card further.

While an intensive process, data recovery specialists are often able to rescue even severely corrupted or damaged files when no other options remain.

Ways to avoid memory card errors

Here are some tips to avoid memory card errors happening in the future:

  • Purchase name-brand cards from reputable retailers to avoid fake cards.
  • Avoid low-cost cards which are more prone to defects and failure.
  • Check your card’s speed rating for compatibility with your phone.
  • Be gentle when handling and inserting cards to prevent physical damage.
  • Never force a card into the slot – it should go in smoothly.
  • Lock your memory card’s write-protection tab after formatting.
  • Eject the card properly before removing from devices.
  • Store cards in protective cases away from moisture, heat, and magnets.

Following these guidelines will help prevent file corruption, physical damage, and usage issues.


Memory card errors in button phones are most often caused by physical damage or improper insertion. Try reseating the card, inspecting for damage, testing with another card, resetting the device, reformatting, and cleaning contacts. For software glitches or hardware repairs, seek professional phone repair services. With proper troubleshooting, you should be able to resolve the memory card error and recover functionality. Be sure to handle memory cards with care to avoid issues down the road.
