When I was searching for a new Smartphone I went through many comments by users at Amazon and elsewhere and found them useful. After I purchased a phone, I thought it was my turn to post about my experience, hoping it will guide someone to choose what is right for them.
I wanted to use a dual SIM phone with a new Reliance JiO connection and my existing Airtel number and looked at various Smartphones. I settled for LYF for the following reasons:
* Since I wanted a JiO connection it made sense to choose LYF since it come with the required Jio apps that I otherwise need to download separately, if I use one from another manufacturer. Downloading per se is not the problem, but the fact that you need to keep checking for updates etc over time and if there are compatibility issues with anything (OS, model features etc) you need to work around it. (If you choose any other model and have a JiO SIM please ensure you have downloaded JiO Join app (the app name has changed recently, please check) from Google Play Store and you can start using the JiO connection provided your SIM1 (4G) has the JIO SIM.
* I am price-conscious and think wasting 14K+ on phones is useless. I would rather invest that money since phones anyway last for four-five years before you are forced to upgrade for any number of reasons.
* I realised even while selecting a dual-SIM phone, I MUST NOT CHOOSE ONE WITH HYBRID SIM SLOTS (Very Important) since otherwise I cannot use the second SIM which will be used by the MicroSDHC card. IT IS IMP THAT YOU CHECK FOR MODELS THAT HAVE AN EXTRA SLOT FOR MICROSDHC CARDS, else you cannot practically use the second SIM, given you will have to download apps over the phone's liifetime and will need a MicroSDHC card.
* It is important that the Jio SIM be in SIM1 on any phone else your Voice calls/internet will not work- so please bear this in mind when deciding.
Given this I decided to go ahead with LYF WIND 4S and it has been about 20-25 days now, I am happy i chose it.
If you are looking for a phone with a good camera, please don't buy this phone. The photo quality is okay. I prefer using a SLR or actual camera for pictures and think the camera in the phone should be incidental for any quick, regular use. Given that belief the LYF WIND 4S works well for me. It will not suit someone who wants a good quality camera in the phone. The Jio broadband connection is good. Voice quality is good when it connects, but there are times when I find I can connect to others with Airtel but not with Jio (out of coverage area it says). That is because Airtel and others are playing hooky and not a problem with Jio per se, I think. Until the inter-connectivity issue is resolved this problem will persist because Airtel and others are causing issues, I guess.
For TV addicts it offers a huge number of Indian channels in many languages. I have just checked once and found it good, but I do not like watching TV on a small screen, not do I play interactive games etc, so I cannot give you any advise on how it performs, if there are any heating problems etc. when used for long.
I found when I used it as a Hotspot my laptop connected well, but some sites did not connect. For example all sites of Google work neatly, but some others gave me a problem. May have been some teething issue, but I need to check again later. I later used my regular broadband provider as I did not want my work to be disturbed.
BTW I have still not purchased (postponed) a MicroSDHC card for this phone and so far have done decent use of Whatsapp and the other Jio apps without it.
Hope all this helps you take the right decision and you are able to buy a phone that suits your budget. If you can wait for some time (after December 2016) I suspect the LYF phone prices will drop much further.
