If the screen of your Smartphone appears completely black, but you can still hear the sounds of notifications, rings, and you receive messages or missed calls, it is likely that the screen is damaged.
Generally, screens that do not display an image or have faults have usually been damaged by impacts, humidity or other improper use of the device. In this case, it is essential to take it to our Technical Service to replace the screen.

If the problem started after installing an application, it is possible that your computer is experiencing software crashes due to faulty applications or applications that are incompatible with the manufacturer's specifications. In this case, it is necessary to reinstall the operating system.
When the battery has reached the end of its useful life, it may cause the device to reboot. In this situation, it is necessary to replace the battery.
Another possibility is that the ROM memory is not physically accessible. This means that during startup, Android needs to access basic boot files and if it cannot read them due to physical problems with the ROM, the device will reboot. This problem is usually caused by falls, bumps or corrosion.
If the internal memory is full and you received notifications that an application has stopped without giving it any importance, Android needs at least 200 MB free to function correctly. In this case, it is also necessary to reinstall the operating system.
This type of failure is not easy to resolve and can have multiple causes. Therefore, when you visit our Technical Service and provide us with all the information possible, we will be able to find the best solution.

If you connect the charger and it does not charge, you have a damaged charging pin:
Before bringing it to our Technical Service center for review, first try with another charger and even another battery, but if it still does not charge and the fault persists, do not hesitate to bring it to our Technical Service to solve it.
This generally happens when they connect the charger to the charging pin incorrectly, or when they apply a lot of pressure or force when connecting the charger, also when they do the up and down game to fit the charger.

If your Smartphone's battery is swollen, it is a phenomenon that we cannot ignore because your Smartphone can be completely damaged.
The main risk and danger factor of a swollen battery is that the lithium turns into gas and this gas combusts, in short it can catch fire out of nowhere. This combustion can cause the phone to end up on fire and you may suffer burns.
For this reason, if the battery does not last a charge or has little autonomy, the battery can explode and cause serious damage. It inflates because the battery has already ended its useful life, because it may have suffered an internal short circuit, or because it is left charging overnight. In our Technical Service we change the Battery to extend the useful life of your Smartphone.

To correctly charge the Smartphone Battery, it is better to leave it charging for a period of 2 to 3 hours, or until the Smartphone says full charge or 100%
This is because there are some smartphones that have fast charging.
We do not recommend charging your cell phone all night, because this deteriorates the useful life of the battery.
You should also not use any charger, the factory stipulated voltage and amperage are for optimal and safe charging of your Smartphone, in our Commercial Premises we have chargers of the correct voltage and amperage for your Smartphone, you can contact us by Whatsapp.

We can optimize the charging duration by closing applications that we are not using and configuring some options on our Smartphone
There are applications that run in the background and consume a large part of the battery. Do not trust optimization applications, they do not work and only steal resources from your phone.
Also check if you do not have Synchronization, GPS, Bluetooth activated and the screen brightness above 50%, these options take up a large part of the energy of your Smartphone.
If even after this your smartphone does not charge, check that the battery is not swollen. If that is the case, check our FREQUENT QUESTIONS, we have the answer and solution.

First dry it well with a cloth then you can leave it near a heater for a short period of time.
For no reason do you try to turn it on, do not connect it to the charger, if possible remove the battery and bring it to our Technical Service.
It could be that it fell out of your pocket and ended up in the toilet, or that it got wet during the rain or even that for some strange reason you went into the pool with it; but as a matter of common sense, no matter how much our technicians manage to get the Smartphone working again after getting wet, it is most likely that the humidity has reduced its potential and at some point it will be damaged again.
If it has gotten wet in the sea, it is unlikely that we will repair the smartphone because the salt in the water quickly corrodes the copper and pulverizes the tin on the integrated components. If this is your case, you may want to buy a new Smartphone.
