I ordered a (Jio owned) LYF C459 4G smartphone for Rs. 3899 from Jio Website on 28th Jan. 2018.
Key specs of the LYF C459 device are: 4.5 inch touchscreen display, Quad-core Qualcomm Snapdragon 210 processor, Dual SIM (4G + 2G), 1 GB RAM, 8 GB Internal storage expandable via micro SD Card to 128 GB, 5 MP and 2 MP cameras, Android 6.0.1 and 2000 mAH Li-Ion battery.
I received the phone by courier on 31st Jan. 2018 morning. After tripping up once, I inserted the SIM in my JioFi3 router (9xxx) into the phone using a microSIM holder to hold the NanoSIM, which was recognized by the device software.
Specified my regular gmail id in the initial setup process. That got completed smoothly.
Some apps including MyJio app were preloaded on the device. Had to update MyJio app which went through smoothly. MyJio app picked up 9xxx number of the SIM as main account. Linked my 8xxx number (used on Huawei 4G USB dongle) to it. Then I was able to view the vouchers associated with 8xxx number! That was good as these vouchers are shown and can be used only via MyJio app (and NOT on jio.com website).
As the device is the rock-bottom price device in LYF phones, it has only 1 GB RAM and ran the software rather sluggishly. So I deleted some preloaded apps which I felt I don’t need, which freed up some RAM as well as storage space.
Preloaded Chrome browser ran well showing fast.com speed test website properly. Decided to delete preloaded OperaMini.
But I could not remove my regular gmail id from the phone! That was upsetting as I do not want to use my regular gmail id (and other ids like Facebook id) on this phone due to security concerns.
Factory reset promised to remove all setup info. that I had provided and so did factory reset. Restart and setup after factory reset seemed to be slower than setup that I did in the first attempt. Created a new gmail id for the Android phone and completed the initial setup with that gmail id.
I repeated some of the earlier setup steps but with more confidence and knowledge. I tripped up on the Hotspot feature but that was due to Automatic Windows Update download getting used on the WiFi connection to the Hotspot. Once I figured the issue out and resolved it, the Hotspot feature worked well.
Overall the phone meets my limited needs for it – primarily as an Internet access device and usage of MyJio app related freebies/cashback vouchers. I also may use its free phone calls facility but the health issue that I have given below may hold me back from using that. So far I have not tested the phone call facility of this LYF C459 device. I use an old Nokia E-52 3G phone as my primary phone device.
Important health note: I suffer from breathing related allergies which includes an allergy to even small amount of chemical gas released by rechargeable batteries in devices like smartphones and laptops. In my short usage of this LYF C459 phone (uses 2000 mAH Chinese company manufactured Lithium ion battery), I think that its battery does release small amount of chemical gas which triggers my allergy. So I need to use it in a manner in which I do not get exposed too much to any chemical gas it releases. But that’s my individual health issue which may not be an issue for most people.
Readers who do not want to know the details may please skip reading the rest of this post.

Yesterday (31st Jan. 2018) morning I received the Jio LYF C459 device via courier. Given below are some key points about the setup I tried out so far.
1. The nano SIM (I believe it is called Nano SIM) in the JioFi3 router, 9xxx, was inserted as is in the LYF C459 device SIM1 slot and failed to be recognized. After some frustration, I tried out using the micro SIM holder template that was there in the Jio SIM sachet to hold the nano SIM and inserted the micro SIM holder + Nano SIM in SIM1 slot of C459. This time it picked up the SIM properly.
2. On setup I provided my regular Gmail Id. It needed a PIN code verification which I was able to do. I had thought that I will first provide my regular gmail id to get things going, but later delete the account (for safety purposes). However, later deletion/removal of the account always tripped up saying that administrator is preventing the removal. More on that later.
3. MyJio app. had to first be updated. On running it (after update), it automatically picked up the first SIM details and plan (perhaps I also logged in with my Jio Id). Later I added the other SIM 8xxx (used in Huawei 4G USB dongle). It needed a PIN verification – I was able to get the PIN from SMS sent to 8xxx number via MobileParter program on PC.
My Vouchers for the 8xxx number lists the 50*8 vouchers (got from purchase of Rs. 399 plan sometime in Jan 2018) as well as another 5 GB or something like that add on voucher. It was good to see that MyJio app. showed this voucher credits properly (note that the website jio.com does NOT show the vouchers and that these vouchers can be redeemed only through MyJio app on mobile device).
4. Hotspot was very slow in my initial attempts. Later it showed better speed. Perhaps there was some setup issue that tripped it up.
5. The C459 device is a rock-bottom price LYF device and so its RAM of 1 GB was almost full. Further the device seems to have a poor response speed. So I deleted the following apps to free up memory and storage: JioCinema, Yatra, Opera Mini, JioMags, …
6. Net Velocity app forced an update on running it but after the update was downloaded, failed to run it claiming that some security setting needs to be changed. I solved the issue by updating from Google Play store where this security issue did not crop up.
7. Fast.com on Chrome shows up properly. Opera Mini has some issues with fast.com display. Decided to delete Opera mini and use only Chrome.
8. Downloaded and installed Ookla Speedtest app. But after factory reset, I have not downloaded it again as I think Net Velocity and fast.com on Chrome may be enough as speed tests.
9. Simply could not remove my regular gmail account from the phone. So went in for factory reset. Restart and setup after factory reset seemed to be slower than setup that I did in the morning. Created a new gmail id for the Android phone. I do not want to have my regular gmail, Facebook and other accounts on this mobile device as of now due to security concerns that I have, of the phone being misplaced or lost at which time my main accounts could be vulnerable to hacking or worse.
4th Feb. 2018
After above-mentioned factory reset (point 9), I repeated some of the earlier steps but with more confidence and knowledge. Barring the Hotspot feature, other essential features that I needed worked. The Hotspot feature did work but I got blindsided by a large automatic Windows Update from my PC over the WiFi connection to the Hotspot, leading to poor speed test results on desktop PC. Once I figured that out and resolved the issue by making the WiFi connection to the Hotspot a metered one (which then does not get used automatically by Windows Update), the speed test results on desktop PC WiFi connection to C459 phone’s Hotspot gave healthy Mbps speeds.
Overall the phone meets my limited needs for it – primarily as an Internet access device with small usage of its free phone calls facility as well as MyJio app related freebies/cashback vouchers.
P.S. Dual SIM on this phone (and other low priced Dual SIM phones) means that one SIM can be 4G but the other SIM will operate only as 2G. In other words, in these low-priced phones the Dual SIM feature does not allow for dual 4G SIMs to be used at the same time. But I think one can change which SIM of two 4G SIMs should be used as primary (4G) with the other becoming 2G. But I have not tried that out.
