Android phones give us many possibilities to customize their interface and make us more comfortable from simple things, such as adjusting the screen brightness to the full setting, so that it can be used by an elderly person.
One of those settings that can be activated so that the various items displayed on the screen appear larger or smaller is to change DPI.
What are IPRs?
DPI is an acronym for Dots per inch or dots per inch In Spanish, it is a unit that measures the number of dots in a print, the higher the DPI, the better the print resolution.
In the context of IPR we are simply measure the amount of information displayed on the screen. If the DPI is increased, all the elements appear larger, ie the letters and icons look bigger, so less information is displayed on the screen and, conversely, if we reduce the DPI, everything seems smaller and therefore more information is displayed on screen.
Depending on the screen resolution and size The default IPR may vary on a small screen phone, such as the Galaxy S3 mini, it comes with 240 DPI by default, on the other hand, the Samsung A3 which has a larger screen comes with 360 DPI by default.
Before making this change, please note that this option is made for use by application developers and not for normal users, so it has its risks and can cause problems on your phone, the most common is that it causes the constant closing of applications such as SMS or Contacts.
In the worst case, it can make the phone unusable it would restart from time to time or maybe it just doesn’t start. If you do not have enough knowledge to deal with these issues, we recommend that you do not apply these changes.
If you dare to change them, do it at intervals of 20 It is the best way to go and in this way adapt it to your specific needs.
