Waterproof smartphones are a reality now. The first one we saw from a major brand was Xperia Z. Despite not getting enough attention, the phone was still amazing in almost every aspect. After that, Sony decided to continue improving the Z series and brought us several amazing flagships. These flagships all had one thing in common; they were all water resistant, yes, the certification kept on improving. Apart from the premium flagships, Sony also released some mid-rangers that had waterproofing. Xperia V and the recently announced M4 Aqua that takes waterproofing to a newer level by introducing cap-less micro USB port.

Despite Sony’s assurance and several marketing campaigns that showed that the phones are ACTUALLY waterproof, consumers were and still are a bit reluctant to test the waterproofing of their phone and at the same time are curious. Luckily, there is a way of finding out whether or not your phone’s waterproofing is still intact. Check it out below.

  1. Open your phone’s dialer and enter the following code:


  2. A new menu will open, go to ‘Service Tests’.
  3. Go to ‘Pressure Sensor’.
  4. Apply a small amount of pressure on your phone’s front and the back using your thumb and index finger.

If all the waterproofing seals are intact on your phone, the pressure will go up. However, if the pressure does not go up despite the fact that all the flaps are sealed, it means your phone’s water proofing seals are compromised. Worry not, you can always order official flaps from several online stores and replacing them is VERY easy. Check out the video below:

Do keep in mind that despite the pressure you are applying, the numbers will start reducing, don’t freak out, that means the sensor is adjusting to the newly applied pressure. For non-Sony users who own a waterproof phone and are willing to test the waterproofing, simply download any Barometer app from Google Play Store and test it using the app.


  1. […] When buying a used smartphone, make sure you carry your set of standard accessories you use with a smartphone, carry a charger/powerbank, carry your earphones as well as your SIM card and microSD card. It is advised to properly check each equipment with the phone for at least half an hour, don’t forget to put the phone on charge for at least 15 minutes to find out whether or not it’s charging properly. If the phone heats up during charging without being operational, there’s definitely something wrong with the device. Do the same with your earphones, and make calls after inserting your SIM. If you are data concious, make sure you check if LTE and 3G are working fine, don’t let other radios go unchecked. Keenly notice the screws and look for any scuff marks around the edges of these holes, you can find a lot about the device by looking at how it’s handled. If it’s a water-resistant phone, simply follow the instructions in this guide. […]
