The most critical moment for the user of a cell phone occurs when – without having suffered a fatal blow – the device does not give any sign of life. And as much as one presses the power button insistently and puts it to charge, it does not offer any signs of improvement. What to do in these cases?
Although problems can have multiple answers, according to experts, the most common diagnosis is that the fault is related to the battery or the operating system.
It is important to remember the previous signs of the equipment –sudden blackout, charging problems, error when trying to access the applications- to know the simplest way to get to the heart of the problem.
If when plugging the appliance into the socket it does not register any activity, the first measure recommended by the specialists is to move the power cord. The indicated thing is to replace it with another and if the problem persists, change the charger for a new one.

Something that is damaged very often in equipment that is more than two years old is the loading port. This is the connector at the bottom of the device where the battery charger connects.
On some mobile phones, this charging port also functions as a fast lane to transfer data, allowing you to transfer information to and from a personal computer.
The repeated connection and disconnection it may cause wear on this port. In many cases this results in a poor or faulty connection with the phone charger.
Replacing the charging port requires you to completely dismantle the device. And although it requires technical engineering, the cost it does not exceed a thousand pesos.
What to do if the screen freezes.
Another of the most common cell phone failures is that the screen remains a still image. When the phone freezes and the home button doesn’t even work, the only thing you can do is force the device to shut down and restart.
Whether due to malware or an application installed from an unofficial store, the operating system can crash. The best option in these cases, considering that no one is an expert in dealing with technological problems, is to try to do an absolute reset to return the mobile as if it were fresh out of the box.
Although this is an unknown function, most Android phones have a system diagnostic test which analyzes the operation of key hardware and software components.
To access this hidden menu – which does not need third-party apps or root- you must enter a code that changes according to the manufacturer of each terminal.
To enter these codes it is not necessary to resort to any type of spatial application. You just have to access to the phone’s keypad, the same one used to make calls.
Here are the codes to access the diagnostic test of the system of the most popular brands.
- Samsung: entering the code * # 0 * #.
- Xiaomi: * # * # 64844 # * # *.
- Sony: * # * # 7378423 # * # *.
- Huawei: * # * # 2846579 # * # *.
- Motorola: ## 4636 ##.
