Back in April, the Infinix Zero 4 (X555) received an important OTA update, a version update from Android Marshmallow (6) to Nougat (7). That update came with some bugs as expected and Infinix has pushed the Android 7.0-XOSv2.2 X555-H538A-N-170521V167 OTA @ 514.30 MB which fixes some of these bugs. This and the Nougat OTA bug fix pushed to the Infinix Hot 4, Note 3 & Note 3 Pro were rolled out just a few days ago.
