1016930 - [ZTE Open C v1.3] [Accelerometer] - Accelerometer does not seem to work correctly

Status: RESOLVED WORKSFORME

(Firefox OS Graveyard :: Vendcom, defect)

Description

[Ralph Daub [:rdaub]]

Hi, 

The accelerometer in the ZTE Open C v1.3 (Ebay US) does not seem to be working correctly.

STEPS TO REPRODUCE:
1. Download and install the game OrbLand from the Marketplace
2. Play the game

EXPECTED RESULTS:
The sphere should move around the screen depending on how the phone is held.

ACTUAL RESULTS:
The sphere does not move, as if the accelerometer (or the accelerometer APIs) were not working correctly.


Please let me know if there is any information I could provide to help with the investigation and troubleshooting of this issue.

Thanks!!

On the Geeksphone Keon with v1.3, the accelerometer work, but is inverted (tilt the phone to the right, the sphere in the game slides to the left).

In my prior statement's result I also so the inversion mentioned. I was not able to determine if that was the design of the app due to lack of tutorial or documentation. It pretty much just says to "rotate".

*Saw the inversion mentioned

The user also reported that the orientation does not seem to work on most of the apps. 

Rachel from the Helpdesk team reported that it also does not seem to work on the games SketchbookSquad or FlappyBird.

I decided to go back test this issue once again, since there was an official update from ZTE with BuildID:20140519040012 -

The game OrbLand still does not work correctly on the ZTE Open C.

However I downloaded an accelerometer app called "Spirit Level" and it works perfectly fine. The game Sketchbook Squad also works correctly now.

It appears that the problem is specific to the implementation of the game OrbLand. Therefore, I am closing this bug as WORKSFORME for the time being.

Thanks,
