I am from India. I have purchased Kospet Prime 2 watch. My service provider is AIRTEL. Its band is B40 (TD 2300) LTE interface. I am not able to connect to the Airtel frequency and use my phone for making and receiving calls.
Ragards,

If you use the search function on this forum there is a lot of information on this . The above is just a example

Anyone know how to access the special code ##3646633## or ##4636##. I want to lock my watch into 4g only. Because I am using it as my hotspot and i have put a data sim that is not supporting 3g for data
You can do this by going to Settings, Network and mobile data and set preferred network to 4G.
It does achieve the same thing.
Those access codes are not the same on these devices and I think if you enable USB debugging - you should be able to use the MTK Engineer mode shortcut app from the play store.
I must admit that I have not done this for a while but it used to work as long as developer options were enabled

Prefered 4g still goes to 3g sometimes. Specially inside building without 4g repeaters.
The apps doesnt work its a shame i already enable developer option and with usb debugging.
Oh well, at least we tried.
Itās probably a carrier problem. Even if the LTE (4G) frequency band is within the range of communication support, it may switch from 4G to 3G if the signal is outside the allowable range or low. In addition, some countries allow 4G data, but VOLTE is blocked, so data use is 4G, and 3G is converted when receiving calls or text messages.
Indeed it is a Carrier situation.
Here I use Telstra.
It works fine with LTE but only if the default.prop has the the telstra branding entries.
But I find that it makes absolutely no difference at all to the quality of phone calls.
4G works fine and Voice over LTE is not important.
So I have tried Vodafone sim and volte is available because they do not have these dependencies.
However, I notice no difference in call quality between the Sim that allows VOLTE and the Sim that does not.
It is the same for cellular dataā¦ No difference in performance.
Of course - there is also the internal antenna signal strength.
If it is not good enough it will seek 3G.
Because of this I have set my network to favour 3G because it is more than fast enough for the watch.
It also saves battery by not hunting for cell towers that will accept it.
Telstra is an Australian carrier. In the case of Korea, it is a little different from what it looks like. Due to the policy of IMEI Whitelist, if the carrier does not register IMEI, VOLTE will not work and the call will be connected to GSM, resulting in actual sound quality differences. I am using SKT carrier.
I donāt know what other countries are like, but this is common in Asian countries.
I hope it helped you, @sinlaojd
Just 1 question
When I try to get into library (in youtube) in square mode taping doesnāt work any1 can explain why it works like that???
(Using original firmware)
Yes, if it does not go to square mode then it is whitelisted in the firmware.
I must admit that I havenāt tried it because it is well known that watching video on these devices makes them very hot.
However, I am very surprised that it is excluded and I wonder if it would be the same after a factory resetā¦ 
Otherwise I suggest that you flash a version of stock firmware from before v2.0 etc.
V1.6 deals with formatting differently and to be honest I would probably try that version.
Actually v1.8 should be fine.

Can we get version 1.6 too? Just out of curiosity for testing purposes.
In FAW worked everything perfectly.I better wait for it

Here you go.
Many of these were never released due to bugs.
But test away ā¦

Iāve discovered (well let me rephrase thatā¦.it was pointed out to me) Prime 2 camera that is really a bit of a nuisance. Iāve always struggled to use the camera either on my wrist or in hand when taking pics and until it was brought to my attention, by my wife nonetheless, it hadnāt occurred to me that the pic was backwards. Not sure if itās intended that way or a one off. Iāve scoured the forum and searched multiple ways but nothing came from any of it which means itās not a big problem amongst the vast majority who own Prime 2ās or itās an accepted issue that comes with the territory.
What I mean is that if Iām trying to take a pic of anything, in order to to turn right, I have to turn the camera to the left and vice versa. As an example: using my phone in selfie mode shows me (damn Iām handsome! 
) with a planter to my right and manās best friend to my left. When turning the phone to the right you see more of the planter and no dog and of course turning to the left shows more dog and no planterā¦typical stuff. However, with the watch, everything is backwards so in order to see more of the planter, I turn left and turn right to see more dog. Not natural movements.
I could never understand why it was so hard to bring things into to frame but now I know.
So the questions herein lie, has anyone else experienced this and is there a fix?
In a nutshell, this watch was one of the earliest released when they became available (so that may play a role) and Iām working with the following firmware release.
(Side note): I just realized it happens in selfie mode only.
Donāt compare your phone to your watch. The phone has two separate camera systems and you do not rotate one camera back and forth.
The original Kospet 2.1 also works incorrectly.
Try taking a photo of a text in selfie mode. You will understand everything immediately.
And selfie mode
To avoid being upside down in the photo, you need to change the image.
The problem is that you rotate the image 180 degrees.
The correct solution is vertical mirroring, not rotation.
We also move the camera up and down on the watch, not around its axis.
I hope it is possible to solve the error.
