Soldering Iron: This tool is used to solder small components like resistors, capacitors, speakers, or microphones. A 50-watt soldering iron should be good enough for most mobile phone repair jobs. For mobile phone repair the soldering iron must be ESD safe because most parts in mobile phones are very sensitive and will get damaged due to static charge. You can get a 50-watt ESD safe soldering iron on Amazon for around 16 dollars. Link on the basics of using a soldering iron: https://www.youtube.com/watch?v=BxeDkcAa4Fs

Anti-Static Tweezers: Another basic tool that most likely will come in a mobile phone repair kit. Tweezers will help by making it easier to grab things when they need to be pulled apart.

Antistatic Brush: Phones normally aren’t opened very often and need to be cleaned when they are. You can’t just use any brush as it might damage the circuitry in the boards. An anti-static brush is used so it doesn’t spread charges and harm the device. A set of anti-static brushes will cost around 5 dollars on Amazon.
Nylon Spudger: This is another essential tool for repairing phones and tablets. The spudger is used for a variety of purposes when it comes to repairing electronic devices. The tool is anti-static and pliable making it ideal for working around electronics without fear of shocking them or scratching them. The pointed end of the spudger can be used to connect or disconnect components or hold objects for soldering. The tool also includes a notch for hooking wires. The flat side of the spudger can be used to remove thermal paste, pry out components and can also be used to aid you in soldering.
Plastic Triangle Tool: This tool looks very similar to a guitar pick and is used to get into those tight spaces to help pry open things. This tool is extremely useful when it comes to do screen replacements because of its ability to help assist in the removing of the glass touch screen from the device. You can use the tool to slide and maneuver around the housing of the device without having to worry about scratching the glass touch screen of the device.
