Why is mobile repairing so expensive?

Mobile repairing has become quite expensive lately, and there are a few reasons behind this. Firstly, the increasing complexity of smartphones means that skilled technicians are needed, which raises the labor cost. Secondly, the cost of genuine replacement parts is high due to their quality and the demand-supply gap. Thirdly, many mobile companies don't encourage third-party repairs, further driving up the costs. Lastly, the need for specialized tools during the repair process adds to the overall expense.
