Lookr Old Versions: Which Build Should You Install?
For almost everyone, the answer is the newest: v1.5.7.1110.01. But old versions exist for a reason, usually an older phone or a bug that arrived with an update. Here are the three verified Lookr builds, what differs, and when rolling back actually makes sense.
Key takeaways: Current: 1.5.7.1110.01 (43.3 MB). Previous: 1.5.5.0306.01 (43.8 MB). Earliest: 1.5.4.0103.01 (43.1 MB). Stay current unless a specific problem forces you back.
The three verified builds
v1.5.7.1110.01, 43.3 MB. The current release and the build on our download page. Latest bug fixes, full test pass on Android 12 through 16.
v1.5.5.0306.01, 43.8 MB. The previous stable. Same visible feature set, slightly larger resource bundle. A reasonable fallback if 1.5.7 misbehaves on your device.
v1.5.4.0103.01, 43.1 MB. The earliest widely mirrored build. Works as a last resort on Android 7 and 8 devices that struggle with newer releases.
When rolling back makes sense
Roll back only for a concrete reason: a crash that started with the update, or a feature that worked before and broke after. Do not roll back on a hunch, older builds miss bug fixes and can lose backend compatibility over time, which is exactly what causes the blank search problem.
How to roll back safely
Uninstall the current build first. Installing an older version over a newer one usually fails with a signature conflict, which looks like the App Not Installed error. Then install the older XAPK the normal way. Your downloaded videos in shared storage survive the uninstall.
