For the best XDA experience on mobile, try our new app, XDA, built entirely in-house: play.google.com/store/apps/details?id=com.xda.labs.play

*Please clear app data after installing v4.0.x if you encounter login issue (settings>apps>xda premium>clear data)*

This app lets you access the world-famous XDA forums, plus reply to threads, add new ones, manage your PMs, and more!

The premium XDA app is ad-free and has additional features versus the free XDA app.

Please note: XDA Premium works best over WiFi or high speed cellular data. The first load might take the longest even if you're on WiFi.
