My phone / laptop repair shop says "part not available". What should I check?

Ask three things: the exact part name, whether it is original or a compatible part, and the price difference between the two. Ask how many days it will take to get the part and whether they need an advance. Before you leave the device, note what is working and what is not, take photos, and remove your SIM and memory card. For a laptop, keep a backup of your files. You can ask 2–3 repair shops through BM Karo and compare.
