Although some predict that the future, smartphones will completely dispense with physical buttons, for now we continue to live with the power and volume buttons on a daily basis . It is common for these buttons to work incorrectly, either due to the passage of time or other reasons.
Dirt, a blow, the passage of time and other elements, can influence a hardware element such as the volume and power buttons of the mobile. In some cases, they are located on the same side, while other variants place them on opposite sides. However, in both cases they can fail at the least expected moment.
When the volume buttons fail.
In this case, the symptoms are very clear. The buttons are stuck, do not return to their position or directly do not respond . As it is a hardware problem that in many cases involves disassembly and revision by a specialist technician, we will have little room for maneuver. However, we can always run a few tests.
Exert more pressure
The side buttons of the phone have a micro-selector designed to avoid accidental pressure, so sometimes it is preferable not to err on the side of caution and press hard.
Remove the cover
If we are using a protective phone case, we will have to remove it and check if the buttons work properly. If we use a third-party case, we may need to use more force to press the volume buttons. By removing it we can get out of doubt and know if the case or casing is the culprit.
Stains or dirt
We will have to check for stains, liquid residue or some other foreign object around the buttons. If so, they will possibly be the cause of the buttons sticking, not returning to their position or not responding. The solution is to use a small brush, or a damp or alcohol-dampened cloth, to firmly clean the area around the buttons at the same time that we press them.
The power button is loose or wobbly
In this case, we will have to take the measures that we have seen previously. However, we are facing a more delicate button , since the correct on and off of our mobile depends on it. If we cannot get it to work properly, it is preferable to go to the Technical Service so they can check it. Otherwise, it could be completely released (internal disconnection) and prevent us from turning the device on or off.
