I owned a 640 XL for two weeks now. Previously uses android phones.
Wondering what kind of games you played on your 640. Platforms, puzzles and strangely RPG games are find on this phone but I'm having stuttering or lag issues when playing racing or action game (Dead Trigger 2, Overkill). You can feel the phone is struggling to run these games.

Again I understand this is an entry/mid range phone but I just want to know if you all are having the same issues. Maybe we can share what kind of game playable on this device.

Did not encounter these condition before. Only get's hot when running games.
Not really hot.. warm would be more accurate.

Btw I'm seeing tiny scratches on my screen..
Anyone knows where to buy some screen protectors/tempered glass.. huhu

.. and also ask phone accessory availability...
So difficult to find..

+1

Got mine Nillkin tempered glass and Imak case from Lelong. Diff to find accessory in shops.

Having Cortana on start page is just a short cut right? Because for Cortana to work, we need to enable the location services... Without it it will not run.. Not sure how it will affect the battery ..

I have the same problem. Very seldom though. Its like the driver didnt finish loading LOL... Just turn the screen Off and On again.

Lol..no.. Maybe next time it happens..

Those are nice photos. Can you share what setting you use?
