Nope. My phone is 7d-503L
There is another ROM for 7D-501L u can check out here

I think the major difference u need to consider is whether u need phone function
X1 has phone function natively while Tab S doesn't, but can sync with another Samsung smartphone (to use its phone function) if u have one. Personally I think it is ridiculous to hold the phone and make calls in public but a bluetooth headset will fix that

Launcher wise, personally I think Samsung Touchwiz is more polished than Huawei EMUI but that is my personal opinion. U will also have more developer support for Samsung devices compared to Huawei

These days Android phone come with 2GB or above RAM so it doesn't lag like those older devices. For me, no noticeable lag for X1. Don't own Tab S so can't comment on that aspect

The screen of the X1 is absolutely fantastic. The colours are simply beautiful. Hardware & specs wise, it is top notch 
In fact, many people asked me whether it is an iPad mini

As a tablet, I think X1 is a good buy considering the small size, fantastic screen and top notch hardware

Hi sordany can't find 7D-501L Rom you mention on the link you give me?

Where is it?

Thanks.
