I am experiencing issues with viewport detection on Samsung Brower 4.0 (different devices: S5, S6, S6 Edge, Note 3). The error is more than 57% of all bad rows. Error always finishes with viewport size 0x-56 (yeah, negative value). Unfortunately I am unable to replicate issue in separated environment. Have someone noticed something like this?
Currently I am using JS tracker 2.5.2. Regarding the source,
detectors.detectViewport() have not been changed.
