Used smartphone search that allows you to find devices based on the original OS and the latest possible OS update.

公開日:

These days, smartphones are quite expensive. However, in terms of performance, many older models from several years ago can still be used without any issues.

Because of this, many individuals and businesses want to buy used smartphones, but what often causes a lot of trouble is figuring out "how old is it?"

For example:

I don't expect to use it for a very long time, so I don't need the latest OS, but I do want to be able to use LINE at a minimum. However, I want to avoid a situation where it's too old and I can't restore my LINE backup, or even download the app at all.

Let's say you've found out the following:

While LINE's minimum OS requirements have recently been updated, even with that in mind, a phone with Android 14 should be supported for a while.

Then, when you search for used smartphones, a model listed as "OS 12" appears.

Would you be able to decide if this model is worth buying?

  • It originally came with 12, and can be updated to the latest version like 16.
    = Can be used for a while longer.
  • It originally came with 11 or similar, and has been updated to 12, but can be further updated to 14 by yourself.
    = Can be used for now.
  • It originally came with an even older version like 9, and 12 is the final update.
    = Cannot be used, so don't buy it.

Therefore, we propose a smartphone search website and app like this:

  • Can search by minimum OS version.
  • Can search by currently installed OS version.
  • Can search by the latest supported OS version.
  • Release date and price are also displayed simultaneously.
