Steps for Troubleshooting in Mobile Repair
No matter what the condition of your mobile, you’ll be able to trust you can count on reliable Troubleshooting steps for mobile repair can be broken down into four fundamental steps. Nowaday it is mandatory to learn How to repair your android phone
#Step 1: Specify Your Symptoms
Step 2. Find and pinpoint the root of your issue.
Step 3: Change the suspected component, and
Step 4, Re-test your component thoroughly to confirm that you have solved the problem. If the issue still needs to be solved, go back to grade 1.
It is the general method to follow when attempting to solve common problems for a mobile fix.
Identify Your Symptoms
If a phone stops working, it could be due to just as easy as a loose wiring connector or as a complicated case of the cause of an IC or component malfunction. Before you start, you should know all the symptoms that can help you identify the correct component. Create a list of every sign you can imagine. As a technician, you should regularly record problems and solutions for later reference.
Determine and Isolate
When pinpointing the source of a malfunction in a piece of equipment, you should ensure that the hardware doesn’t cause the issue. It is apparent in some cases; however, it could not be in other instances. An incorrectly or defectively programmed piece of software could cause confusing system malfunctions. If you’re sure there is a hardware issue in the system, you will be able to determine which part is at fault.
Replace
Since phones are built as sub-units, replacing a sub-unit is usually more straightforward than repairing it at the component level. Even if you have the opportunity to identify the malfunctioning component, many components need to be compatible. Therefore, replacing the damaged part is better than trying to fix it.
Re-test
After a repair is completed, the system must\carefully assembled before being examined. Before testing is completed, install all guards, housing cables, and shields. If symptoms persist, you should reconsider them and narrow the issue to the other parts of the device. The equipment is restored to service after the symptoms have been confirmed to have been stopped during the operation. In general, keeping the system operating for a minimum of a few hours is recommended to ensure that the replacement component is not prone to fail prematurely. It is important to know about How to repair your android phone
Don’t get discouraged when the equipment persists in failing. The software settings and driver software for the device need to upgrade. If you feel exhausted, step back, wipe your hands, and start defining your present symptoms. If you’re tired or angry, don’t proceed with the repair. Tomorrow will be a new day. Even the most skilled troubleshooters are prone to becoming overwhelmed at times.
This article will examine the primary methods used in finding faults or troubleshooting procedures within Mobile Repairing.
Steps for Troubleshooting in Mobile Repair
Operating Voltage for Mobile Devices
It is essential to comprehend the voltage that operates a mobile phone. Be aware of this since it is the initial step to diagnose any mobile phone with a problem. Its MBV for the battery should be in the range of 3.7V to 4.2V. The phone won’t function when the battery voltage exceeds the stated capacity. In this situation, you will need to use a DC Power Supply or Battery Booster to increase the voltage of your battery to 3.7V.

Methods of Mobile Phone Diagnosis
There are two ways of diagnosing damaged or defective parts of a mobile phone. The two methods are as follows:
Method of Cold Testing
Method of Hot Testing
Steps for Troubleshooting in Mobile Repairing | Cold Testing Method
Method of Cold Testing:
Cold testing occurs through the use of an instrument to measure voltage. When fixing a fault on a mobile phone, examine the resistance of the phone. Don’t use any device to charge the phone during cold testing. To find a problem within the mobile phone, make use of the diode range of the multi=meter and then sound the beep. How to repair your android phone
In cold testing for cold testing, connect your Multi-meter’s RED investigation directly to the surface of the mobile phone’s PCB, and then utilize the BLACK investigation to contact the phone’s testing points. The following should be the accurate values throughout the repair and fault-finding process of each component, piece or section:
500700 Ohm Earphone Connector Tip (+, -)
(+,-) Loud Speaker / Ringer Connector Tip: 300600 Ohm
(+) Battery Connector Tip: 250600 Ohm
