i am using a Lumia 640 since december 2015.
despite correct hardware specs Lumia 640 offers a very poor user experience since win 10 upgrade. Every subsequent update of win 10 make things worse (remove functionalities) and does not fix the obvious and numerous bugs. it is NOT a recomended purchase.
i bought this phone lumia 640 dual sime last december evrything was ok till last august one day all the pictures gon on black and if i take new pictures they will be deleted automatically after new start .... can some one help me to fix this?? thanks
I have been owning this phone since 1,5 years already. In the beggining the phone was fine, quick, no lags etc... I was satisfied. but now after update to WP10 and the much worse unniversary update, my L640 is slow, store does not work at all, no chance to update the single apps. I mad hard reset several times, the same result. I cannot roll back to WP8.1 unfortunately. and not to forget about the very poor battery power. My phone spends more time on the charger, than in my hands. So I am very desperate because of this and planning to get another phone...
Considering the latest OS updates with Win10, which is better to buy, this or the Lumia 550?
