[Q] Potentially bugged firmware on local brand tablet
Would like your expertise on this one.
Recently got a new local brand tablet:
Brand Name: MLS
Tablet Name: IQTab silver 3G
Android Version: Jellybean 4.2.2
CPU: 1,2 GHz Quad Core
The tablet is in a continuous "lag" state from the 1st time its worked, meaning that even normal swipes with a finger feel slower and the transition animations on any screen, even the lockscreen unlocking animation has "tearing".
Additionally there is no animation when rotating the tablet where there should a kind of animation where you would actually see the screen rotating. When an app is opened/closed there is also no "fade in/out" animation. I've seen all these animations in previous tablets of theirs with inferior hardware.
Lastly the on-board youtube application was terribly bugged and even after updating it there is a case of tearing in the video when its in full screen and the video overlay pops in/out.
Thought about a defective model but since I got a 2nd one from the shop and both have these symptoms I'm led to believe otherwise.
The tablet came with pre-installed apps that are basically its selling point since people, myself included need those(GPS related). Those shouldn't be the reason since previous models have those same apps and don't exhibit the above symptoms at all. Is it possible the firmware is bugged? If so is there a way to fix it without losing those pre-installed apps?
Will provide additional info about tablet if needed. Any help would be appreciated, thanks.
If this doesn't belong here please direct me to where I should post.
