Some Important Tips For Those Who Want To Repair Their Broken Mobile Phones:
At the moment you found out your phone is broken, in the first place you should check for message or error your phone shows. And then Google it to know what does it mean. The problem might be cause of a little problem and it’d be solved by an easy trick. or if you know somebody who experienced the same problem, you can ask them for help.
If you are about to go to mobile repairing places, ask for master of mobile repairing or go to a good and experienced and known repairman, otherwise, if you go to the middle, repairing process would cost expensive!
If your phone’s LCD is broken, in high possibility, the repairman would tell you to replace and change the LCD and touch and if you allow him to repair your device, it would cost expensive. But if you find and buy the LCD and touch of your phone device yourself and then go to repairman and ask to replace it, it would cost cheaper and you should pay the wage only. This would definitely cost cheaper than the repairman buys the LCD and touch himself and then replaces it.
Also ask for the invoice and also ask for the broken piece.
Sometimes, repairmen would tell you other problems your phone have, and they want to repair and solve the problem/problems. try to let them repair and fix the main issue, not other problems.
At the end of the repairing process, when your phone is ready to go, check your phone before you leave the repairing center, because there might be a problem caused by removing and replacing the broken piece.
