Yes i have do that : reset, default setting and install Google TTS. Same problem : Speech synthesis unusable by the apps.
After a second full reset of the watch and install official Google TTS from PlayStore : same problem i have explain before, TTS Engine doesnt work correctly and unusable by apps. Sure there is a defaut TTS engine in the firmware at the beginning and he create a conflict when install official Google TTS from playstoreā¦
iām also having problems with signal use. when i try to update weather it says updating but doesnāt. then after 2or more hours it updates. iāve put it to unmetered and to use device mac. to no avail. the net itself runs good.

you need to create a new TTS thread in this kospet prime 2 subforum.

After noticing a similar issue with the built in weather app I found the YoWindow weather app to work much better and with a lot more info / options.

cool app. the built in weather app updating is hit and miss. the way it acts itās the app itself. the internet itself runs great. so weāll see what happens in the next update. i got the stock weather app going again by shutting down the watch and turning it on again. still hit and miss though
Hey Pablo. Did your watch arrive yet?

I already asked myself if you could possibly be a kind of vampire. You seem to never sleep and always, always help here at the forum.
Big kudos and get some rest to get well soon.

Has anyone tested UL always on time on the prime 2 - with no other apps running in background and watch on power saver mode, if none can anyone test and share the results? looking at getting a watch with similar battery (lem14) but as I donāt like the slow wrist gesture response time I prefer to use always on time.
Iāve been using Kospet Prime 2 for almost two weeks. I took root without TWRP to install some applications to optimize Android, and so far I am satisfied with the result.
This does not seem to have the problem of the previous watches with draining the battery with the 4G on.
Itās quite big, at first it scares you, after a few days you get used to it. It is not heavy compared to size.
I had problems with four models of previous watches with the USB contacts behind the watch (corrosive sweat), so I decided to stick an adhesive tape (which leaves no glue) after each recharge of the battery, on the four USB contacts on the back cover of the watch to do not come in contact with skin sweat, it may work.
It seems that Kospet is not registered in the GSMA database, so it is not approved to work in Brazil, I had to change the IMEI number, otherwise it would be blocked.
I made some measurements on the battery capacity, and after about six cycles, there is something close to 1600mAh informed by the manufacturer.
As for the temperature, of the five watches I had, the Kospet Prime 2 is the least heated, under medium and heavy tasks.
The 12 oāclock camera on Kospet Prime 2, in my view, is by far the best camera position. The camera at the 3 oāclock position, for me, is almost unusable.
The system has some bugs, it also needs some improvements.
The orientation of the camera should be done in the system and not only in the native application, if using a third party application, the orientation of the camera is wrong and has to be corrected with further editing.
Most Chinese smartwatches suffer from low quality, low durability and lack of spare parts, as the durability of the Kospet Prime 2, only time will tell.
Overall, so far, I found a good watch.

I have the watch for almost two weeks. So far the only problems that i have is two.
Problem 1 - The bluetooth range is very weak and i can not use bluetooth headset to make calls because the people from the other side of the call they say that can not hear me well. If i close the bluetooth headset and talk from the watch everything is ok but i want my phone calls to be private. I tested with two different bluetooth headsets and with any other phones that i have and they dont have problem.
Problem 2 - The gps signal lost itās position very often. I try to navigate in some places in my area with my car and on google maps and any other navigation program i ve tried show me for some seconds in the correct position i am ,and for some seconds wrong position .
Maybe there is a way to fix to improve that problems in an upcoming update ? Maybe the watch have weak singal general?
I have make reset the watch 3 times with no luck in my problems .
Is there any solution ??

LEM14 does not have same size battery as Prime 2, it only has 1100mA, as you can see in corrections in the LEM14 thread.
Thanks - yes I did see that mentioned on the LEM14 thread. Itās the only A10 watch Iām interested in getting though and the Prime 2 is the closest in terms of battery size.
Thank you for the detailed info.
Are you having any problems with bluetooth with headsets and weak gps signal?(if you didnt test these can you do some testing please?).
Thanks in advance.
Is it true that ips and non-amoled screens were not designed to work well with always on display? In other words Could aod harm kp2 screen ??
AOD donāt affect IPS screens as much as AMOLED screens. AMOLED screens will be affected much faster - in other words.
Does that mean its not recommended to use aod with amoled screens frequently to spare the screen?!
