I bought this mobile nearly a year back from Mobile Store for RS. 17750/- with additional warranty and insurance. Like anyone, used several mobiles from almost all brands Nokia, Samsung, Panasonic, Motorola, apple. and operating systems from Symbian, android(starting from froyo, gingerbread, ice cream sandwich, jelly bean), ios.
I bought this as the Samsung android mobile I was using started giving so many issues including but not limited to frequent hanging, heating, sudden reboots, freezing in the mid of the call or sometimes not allowing to even click on answer when it is ringing. Moving to custom rom instead of the original stock rom helped a lot. The GPS was the worst part of all and totally useless and battery monger. Camera was good but that come last in our main requirement of a phone. With all issues keep nagging me, I just went ahead to try Nokia again remembering the good times enjoyed with those simple models and later totally forgot that brand.
I went for white colored Nokia Lumia 720 as I was in a dilemma to have it for me or give it to my wife. Not sure but mostly ladies never like black. I personally prefer black color for most of the gadgets and car. Started using with no much expectation except for calling. Usually exploring various features would be my first focus when I buy any gadget or electronics but this time I even did not bother to set password. The shop sales person took my old regular sim and cut it to micro sim and inserted it for me and activated it. The phone comes with a small pin for opening the sim slot and it is sure worth to retain and keep it safe.
The size was pretty perfect and fits in the palm without paining or stretching. Built is sturdy and the edges and gaps everywhere are so perfect we wont see the joints. Screen is scratch proof(not shatter proof though). Top there is a slot for micro sim and audio socket(regular 3.5mm), left it is flush just with concealed and flush micro SD slot, right has camera, power and volume rocker buttons, bottom has the micro usb for data and power. Sad part is the battery is permanently fixed and user cannot replace or remove.
Holding the windows key(center bottom) and the clicking the power button takes the snapshot of the screen. Camera is with flash, auto focusing and touching an area makes the camera focus to that area leaving other areas blurred giving an excellent results. Camera is amazingly good. Nokia camera software allows manual adjustment of various parameters to take professional photos but normal point and shoot gives an excellent photos. Sound is exceptionally great for such a small speaker and phone, additionally it supports graphic equalizer.
Above all the feature what I really like a lot is the excellent GPS. I am using GPS for almost more than 15 years now. sure I can say that the GPS in this Nokia mobile is the best. It works so perfect with high sensitivity even when you are inside the cab(not near windshield), inside most of buildings(near window or openings) and the best part is within the AC Coach of a Train where every opening is almost sealed and closed for AC. The startup / warmup time is almost nil, it works almost instantly or max within couple of seconds. And the best part is, while using GPS it never sucked the battery like other phones. To me GPS is the feature I like of all other features.
Battery life is very good, lasts for almost two days on regular use but when traveling it goes down pretty fast(not sure how roaming affects it) and keeps it just sufficient for a day. overall. Overall it is a value for money. Nokia recently sent the Black update for its lumia phone which added additional capability. This is the second update, the previous amber upate added the radio feature to the phone. Talk time seems to be at least more than 5-6 hours as that is the maximum time I used
So far in almost an year use, I never had any hanging or freezing issues any more. Windows operating system is maturing one and you may see some of the features and applications not available in this at least for a period of time.
If you are a developer you may not like Windows operating system as most of advanced application developer API and features are hidden and protected and made unavailable in the name of security. So you may not like Windows OS.
For normal users, who wants a good phone with all necessary features this one is an amazing, reasonably priced and no fuss great phone. Not sure about Nokia service as so far no issues and not availed it so no comments on that part!
Personally I love this model even after nearly a year of usage. Highly recommended!
