There is a weird issue I am facing with this product. The touch is not smooth as it supposes to be but this is not the main problem. The phone touch works as it supposes to work when I am using the phone while holding it in hands but when I am trying to use it while putting it on a flat surface the touch is not responsive at all. It may be a hardware problem of any sensor may be grip sensor is not working properly but I didn't expect this from Samsung. Also when I compared the colors of this phone with other products of Samsung. The colors are quite faded and dull. While I really appreciate the amazon technical support team as they run diagnostics on my phone and as soon as they realized there are some issues they are providing me a replacement. But Samsung you **bleep**..! I recently brought A50s also but there is no issue with that product. I think it's some bug or glitch or software or hardware issue with A50s. Please watch the attached video if you don't understand the problem I am facing.
