First of all I have this phone for over 6 months, and overall its a good phone in its price range, maybe the best, but comparing it with Note 2 and 3 is just ridiculous, and I think you didnt even own those phones, and if you did you would never downgrade to E4. But samsung core phones, I can believe that, but it doesnt even come close to note series.
Camera on this phone is barely average, in low light it produces very bad photos and videos, even in the daytime it doesnt shine in that department, there is always some yellowish tint in the photos and noticable granulation even with very steady hand, the flash is more useful as a flashlight than for taking pictures. My 2, 5 years old LG L9 has a one class better camera performance, the front camera is ok.
Display is also very average, but its a 5 incher, so its ok overall, nothing to whine about in that department.
Voice calling loudness and quality is on the better side but only after you turn on clear phase and other sound enhancers, which use a bit more battery juice, which is not good, but its only loud enough, far from outstanding as you said.
Phone’s software performance is pretty stable, but I noticed that when using some apps like swi.tkey, it tends to slowdown, but not that much.
Another thing I dont like in all sony phones is that you CAN NOT change the order of the homescreens in the helicopter view, and on this model you dont even have anywhere to see the total call time( s) of the phone, which is very weird and immature from sony, there is no usb otg also.
You mentioned quality of the charging cable, but why didnt you mention its length which is about only 10 cm, another minus, and the quality of the headphones included is mediocre at best, but at least there is one.
And did I mention there is no LP update in sight in near future, how about that?
Only things that are really commendable are the battery, the audio( music reproduction) quality of the device, LED notification and the STAMINA mode, so there you go, an objective view of the phone, not some fanboy’s view.
It’s worth the money you spend on it, that’s all, faaaar from outstanding.
