Bluetooth Smart / BLE

Hello All,
I've heard from many sources (also official) about BLE availability on Android 4.3 (from software side) for Samsung S3, so just after last update of my phone I've just bought Sigma R1 HRM but... it doesn't work on ANY (I've tried five different) 4.3 ROM. Only CM ROM (4.3.1) could pair properly with this HRM. So this functionality was included in 4.3 or not? Maybe someone could help to pair BLE accessories with SGS3 4.3?
What's more interesting. my girlfriend's Xperia V could pair with Sigma on Android 4.1.2!!! I don't know how it is possible if it is one of key feature 4.3?
P.S. Just for info: Endomondo on Android cannot handle BT Smart, it is not connected with android version.

[Q] Eastcom M3

Hi there, a friend of mine has got himself this Eastcom M3 Dual SIM mobile phone from China on eBay (that's a big mistake in my opinion) anyway, the phone has Kitkat but it just looks dodgy... The boot-loader is all in Chinese too. The actually design looks like a rip-off from Nokia Lumia's early devices.
I have a HTC One M7, is there a way to flash the firmware then instal a European ROM into the M3 to look like the M7 software? Ive found this ROM http://www.needrom.com/download/alps-m3/ but not entirely sure if its right or what to do with it.
Anyone ever had this phone and same / similar problems? i have ADB & Fastboot tools (SDK) etc ..
Thanks for any help in advance, nice one!
Tip to my friend: Don't buy phones from China on eBay!!

Judging by what you're saying it shows, you are compatible, Android Wear is compatible with 4.3 and above. However if your phone only has Bluetooth 3.0 support and not 4.0LE you'll see some battery drain outside the normal amount specified by both users of the device and the manufacturer. This is because 4.0LE maintains a link with the device without actively being connected to it causing it to use less power to communicate, 3.0 lacks this ability so your phone would need to keep an active link with the watch at all times.
That being said, don't let that discourage you from getting it, your phone is completely compatible as it is now and should give you an alright experience with the device. I personally love my LG G Watch and feel that it's the best purchase I've made in a long time.
thank you so much fantastic answer admins can close the thread

Will I be able to update this I9300 to >4.4?

I'm new in Android world, and I have to buy cheapest Android phone that will be able to handle Android 4.4 or newer.
I have found that the best option is Galaxy S3 and that there's one on Aliexpress. I'm aware that it might be a clone but it will not be my primary phone. It just has to be able to handle newer Android.
Can't post a link, search for the top ordered Samsung Galaxy S3 I9300 on Aliexpress.
Has anyone tried it? Will software see it as genuin S3? Thank you!
if it's a real i9300 then you are only able to upgrade via custom rom. Official support via samsung stopped at 4.3
If You need official KK (4.4), then You must search form S3 4G/LTE (9305). Basic S3 ended with 4.3 (as maultasche said).
This must be S3? If not, try search Moto E - it's cheap and small chance to buy fake one - in S3 (generally in Samsung phones) it quite ease to buy fake/copy when your search for cheap phone.
You are right, thank you! And I will check Moto E but what about S3 Neo?
S3 Neo has 4.4.
You can check every Samsung phone here: http://www.sammobile.com/firmwares/
Just type model name/code (S3 or 9301) and it will find all/latest version of firmware.
It you want a phone for calling/texting (and using in general), you should list your needs/requierements/max price and ask what to choice - XDA probably has a place for it.
If you want a phone for testing/development Android apps, you should think about Motorola/Nexus or some new models with offical long support (ie Xperia family).
I just need a >4.5" phone for general use, with at least 4.4 (to use with smart watches and bands). With as low cost as possible. Galaxy S3 Neo is my leader now.
I don't know where I You from, what models ara in your country and in what prices, so it's hard to suggest any model.
I suggest You to use some kind of price comparation site (in our country), choice your requierements and list devices. Then choice what you like (what looks nice to You) and has a good price.
Then paste list of interesting devices.
For example there are couple of cheap models named "Core" or "Grand" (from Samsung) with screen size obove 4.5 inch and new Android.
Downsides are: not so "strong" CPU/GPU (for games) and lack of light sensor - it shoudn't be a issue as You want to use smartwatch anyway.
In my opinion s3 is best choice As long as there is ANY chance to get some cm (official/ unofficial)

You can upgrade it even to marshmallow why KitKat?
As we are expecting the official cm to release tomorrow so I think that s3 is the best choice. And if you just like touchwiz s3 has 4.4.4 ports from touchwiz and you can install them. But I recommend you to install lollipop 5.1.1 rom if you buy a s3 device. You chose the best device if you want any help on how to flash these roms just reply my post.

OnePlus X Bluetooth connection problems?

Hi everyone,
I own a Huawei Watch and had a OnePlus One for about a year. Installed system was Cyanogenmod 12.1. Everything worked fine but I wanted a new phone so I sold it and bought a Moto X yesterday. The first thing I did, as usual, was to set up the system. A problem with pairing to my Wearable came up, several times I tried to pair and finaly it worked. The watch set up and I wanted to install a few apps through the android wear app. But then the bluetooth connection dropped suddenly.
Switching off bluetooth and on didn't solve the problem. so I had to restart the phone. after that the connection worked.....for approx. 5 min.....then it drops.
On the internet I read much about bluetooth problems on Moto X devices all over the world.
So, I have to retour the device to the shop where I bought it. I need another device, the OnePlus X is a really sexy looking thing, so please help me. How is the connection on that device? Can anybody tell something about that issue, maybe flashing of cyanogenmod helps?
thx
Nobody cm on that device?
Hi,
I was having bluetooth problem (drop, disconnecting) with my previous phone (THL2015).
I bought the OPX and i have no more bluetooth problem (with stock rom and now with CM 12.1)
It work very well with CM 12.1 (very fast and smooth) and the OPX has a nice design (so sexy )
Philomen
Thanks mate
