A while back my trusty Nexus 5 phone started to develop problems. The phone started to turn itself off regularly and eventually got stuck in a bootloop, not being able to start again or even able to enter recovery mode.
After looking around on the internet I found out that this is a common problem with the Nexus 5. The mechanical contacts in the button malfunction (often around the time the warranty expires) and the button signals being in a pressed state, despite not being pressed.
I tried some of the commonly recommended fixes I found online, such as repeatedly tapping the power button with force, but none of the solutions I found worked for me. The only thing left was to replace the power button, which is what solved the problem.
To help you repair your LG Nexus 5 phone, I have described below how to replace the defective power button, as well as the materials and tools required.
After the button has been replaced the components of the Nexus 5 are put back together in reverse order in which they were disassembled. When reconnecting the flex cables make sure to connect the battery cable last. That way there is no current flowing when connecting the other cables, and no connections can be accidentally shorted out.
My phone worked almost perfectly when I booted it back up, except for the wireless charging and NFC that did not work at all. It turned out that I did not snap the back cover in well. After putting some pressure all over the back cover the cover fell into place and the phone was back to its original state. If you have the same issues with the NFC and/or wireless charging after repairing the power button I recommend making sure the back cover is placed correctly.
It has been a while since I repaired the phone and it still works as it is supposed to. I am glad I was possible to extend the phone’s lifespan instead of having the phone end up on a landfill somewhere, all because of a tiny button that only costs a couple of cents.
