There are different types of covers gloss and matte for both 640 and 640XL. You can always find a replacement cover for cheap on eBay or AliExpress.com.
Good luck.
Well, I think they just did the same what they had done for 730/735.
When L730 and L735 were launched, L730 supposed to have a glossy back cover unlike 735 (per their initial reveal), but I received L730 with Matte cover
Mine turned up this morning and it has a glossy white finish as well. Pretty annoying as I really wanted the Matte finish. Know if we can get a replacement cover anywhere easily?
I want someone to make a after market Green back cover. That would be sick. Until then i guess its the ugly white. I m going naked on this phone, my main motivation to buy a cheap phone.
Yes, thats that is the case but at the time of writing that post some 2? months ago a large official reseller in Scandinavia falsely advertised it as a wireless charging cover.
