Smartwatch GT08 / CK3s / Oumax S6
Ok I'll try a short review then...
Hardware
The watch arrived today and on the first sight it looked really cool and good quality. It's big of course but not too big and I like the design very much ( seems they 'borrowed' it from the apple watch) . The belt can not be changed because it contains the nfc antenna. This is bad, because the shutter is really annoying and bad quality. You can insert a micro sim card and a TF card into the watch, so it can be used as a phone itself but I didn't try it out. There is a built in camera but it has only 0.3M and the pictures are really crap (sorry for that). The screen ist colorful and bright but its not IPS and the viewing angles are very small, the touchscreen works very good.
Software
The watch has some strange chinese proprietary firmware and not android wear so it is not possible to install any apps. In fact it feels like a litte time warp to the time before devices had android. There is a filemanager and I've copied some java apps to the watch but the system doesn't know what to to with them. Some of the pre-installed apps don't work either. There is a browser (useless because you don't have wlan or 3g) and a FM-Radio which is also useless, because you have to plug in earphones as antenna and the watch simply has no jack für earphoes. One app is a qr-code to download btnotification software for your smartphone, but the code points to a dead link. There is a pedometer that works, but I don't know what it actually does (at least it doesn't count steps) and some other smaller things (alarm, stopwatch, voice recorder, sleep monitor, etc..)
There are only few possibilities for personalisation: 3 (boring) analog watch faces and 3 themes (meaning backgrounds for the menus).
Bluetooh pairing worked well and after I tried some apps from the playstore I got notifications from my smartphone at last. I was able to remote control my smartphone to make and receive calls with the watch and to access the contact list of my phone. I've tried to use a bluetooth headset with the music player but the sound quality ist so very bad, its abolutely useless. So you have to play the music on the tiny built in speaker but who would want that? So the music player ist also useless, which would have been an important feature for me.
my opinion
Don't buy! I will definately return it to the seller, because it is so very not what I wanted.
Ok, it is a cheap watch with benefits and a telephone funktion. The design and built quality is very good for a chinese smartwatch but when it comes to usability, customisation and all day handling there is hardly anything positive to tell. I wanted to post pictures but I didn't understand how. I clicked the icon and was asked to enter some url? Anyway there are some reviews on youtube, just enter one of the names GT08 / CK3s / Oumax S6 which mean all the same device.
