Hello guys, I had been using moto E 1st Gen phone since past two years, and Im totally satisfied with the built quality in fact its a best looking phone under its price range, with 4.5inch gorilla glass display the display quality is amazing I didnt notice even a single stretch on the display as Im using it without any screen guard, I dropped the phone several times but it survived everytime even the battery backup is decent you fan expect whole day with moderate usage if you are a heavy user then battery will juice down in 4-5hrs, the only bad thing in this phone is camera quality, its annoying as it had no auto focus feature it cannot capture any details.
Talking about the performance its good with kitkat 4.4 version I hardly notice a lag, but if you upgrade it to lollipop then you will notice some lags, bugs, so in my openion never upgrade, the audio quality of loudspeakers is pretty decent, when you use earphones its gives you a good feel if you use a good quality earphones like JBL even the call quality is good.
