The LED brightness of Sony Xperia Z1 is not very bright. Sony has limited the brightness may be to protect the LED from damages as well as to prevent burn out of images when taking picture with flash. However, when you using your Xperia Z1 as a torch, found that the light output is less, you can increase its LED brightness with a simple Mod.
An XDA member, olokos has come up with a simple Mod that can increase the LED brightness of Xperia Z1 when it using as a torch or when it using both as torch and camera (depending on the mod). However, keep in mind that DO NOT leaves the LED on for a long time, as the increased brightness will damage the LED as well as the internals of the phone.
The LED brightness Mod for Xperia Z1 is available as zip file. There are three Mods – Extreme (just for torch), Medium (for torch and camera – recommended) and Extreme for both torch and camera. Once you flash the zip file through a custom recovery, you will see the difference when using the torch app (depending on the mod version).
