LEMFO LEM P 4gb + 64gb (Prime style watch) support thread

Here is the latest offering from LEMFO
It is an Android 9 dual chip device like the Prime S
Here are the details:

It looks great…
I wonder about Android 9 and battery consumption.

MrTicks, we need you!!! Help!

With a 500W camera, it’s gonna suck the battery like hell !!


Yes it is funny how description is explained :sweat_smile:

Just to be clear…
These Android 9 unisoc chip devices are unable to make calls or receive SMS in the long standby mode (or sports mode as it is called this time).
Unlike the MTK version (Optimus 2) which can.

Nice looking and reasonably priced but lacking the functionality of the slightly more expensive MTK solution.

The new Prime S is exactly like this but with less ram and storage.

A review from Mr Ticks


After testing in the long standby “Sports” mode, the LEM P actually CAN receive calls if the default Airplane mode is switched off in the swipe down screen that appears in this special mode along with a brightness control.

Of course, there’s no calling out, unless…

Button Manager with Organized Drawer (or any other way of bringing up all the apps) will give access to the phone, contacts, call logs, etc., and it works! All the time you’re in Sports mode, not full Android mode.

I don’t have any battery tests to compare the two modes, or if the Sports mode is significantly shorter life with a SIM in and Airplane mode turned off, so not sure how beneficial all this is in the long run.

BTW, it seems that whatever settings for Bluetooth, WiFi and cellular data you set before switching to Sports mode remain in that state in Sports mode with Airplane mode off, and there’s no way to change them without switching back to Android mode to get access to the full controls (unless, of course, you access Settings through Organized Drawer and navigate to network settings and toggle them there.

Have any of you guys tested any of this on your LEM P?

Also, as reported, the LEM P has 5MP images from both cameras while the PRIME S has 8MP sized images from the top camera. My guess is they are both 5MP modules but the PRIME S is up-scaling the images. I haven’t shot comparison shots to confirm though.

Anyway, as a followup to the Genesis, this LEM P is pretty good without having a rotating single camera at the top but two fixed cameras. I still like the Genesis putting the selfie camera on the 9 o’clock side rather than the 3 o’clock side as your fingers invariably cover the camera when touching the watch in that position. It is what it is though, and glad there’s a top camera rather than on the side.


Again, just so everyone knows…
The LEM P, Prime S, Optimus 2 and any of the other supposedly “Dual Mode” watches are not Dual Mode in reality.

Unlike the original Optimus watches that did have “dual operating mode” and the watch would boot into the BT environment.

This is because the Dual System mode is actually just a cut down version of the launcher that prevents the user from using the majority of Android apps and some services. So booting into the BT system is not required and does not happen. The BT system chip in this case is used to handle the sensor information and it does a good job of this.

On these devices, when you use the “other” operating mode you are effectively invoking a strict power saving mode - but only because the launcher changes and prevents you from accessing the regular apps.
Hence if you can get around the restricted launcher - phone calls and everything else still works as normal. You can easily verify this by installing a third party launcher.

I am saying this because I believe it is fair to be honest about the so called “Dual System” mode and I believe that the brands have not been completely transparent about this.
In fact, to the extent that I actually believed (before I got the devices) that they were indeed like the original Optimus watches and we would be booting into the BT chip environment.

Just an FYI…


Excellent explanation @pablo11 as I was wondering how we could be in one mode but access apps that were supposedly restricted to a different mode. So it’s really a magic trick with launching a different, stripped down launcher to keep the user away from some stock apps and all 3rd party apps plus handing off sensor monitoring to a different chip. Yea, not a true dual mode operation at all. Thanks for clarifying. I guess this approach does provide some gain in battery life, if nothing more than keeping users from using the watch as much.

I still like that PRIME S/LEM P fixed camera at the top and hope to see it bumped up in quality and wrapped in a waterproof watch case someday.

Yes, there’s nothing wrong with it and in fact it really does save power… Just not quite the way expected :joy:

The extra system chip for dealing with sensors and BT functions is actually a good idea…if it was the primary point of having it.

Properly implemented it would be very efficient and accurate.

I am talking to Wiiteer about this exact possibility. It’s not easy though because the brands want what they want and it doesn’t always line up with our thinking :grin:

I removed your post because -
This model is made by the same company that makes the Kospet watch and has a different camera set-up, different design ID and a different board. Like the old Genesis, the top camera is facing out and not up.

Domino is the factory that makes both of these models and many more. (like the LEM T, LEM 10, Ticwris MAX, Kospet Note Kospet Prime S as well as their own DM models)

They produce them and brands buy them in bulk and put their name on them.

I have explained this many times in various threads.
Please refrain from making assumptions.

A quick review from Mr Ticks and FYI - it is not like a LEM P - it is a LEM P.
In reality the DM30 is the product name and then the brands call it what they want.

I did get the 1Mb/16Mb model of the LEMP. It works great but the camera quality is more of a 2MP than a real 5 MP.

It feels like there is more upscaling than expected.

Can you compare between the Prime S, the DM30 and Lemfo LEMP 4Mb?

Prime S and the 1+16 version of the LEM P are exactly the same board.

I have a black screen on my lemfo lem P (1/16), what can I do ???
I can no longer use multitasking to recover it because I closed all the applications thinking that it was lack of ram memory to run the operating system, the clock turns on a black screen I can receive calls and I can see the name of the contact and I can answer the call but the launcher does not activate to enter the menu, I connect it to the pc and I can see the files, I deleted all the contents of the clockskin folder thinking that some face was causing problems but it did not work, I have floatingtoucher installed and when the screen went black the button It kept appearing and I was able to enter the menu but I did not know that the damage was already there, if I had known from there I could have recovered it, the problem was that I restarted it and there everything was lost because the floatingtoucher was not configured to start with the system and there it is already dead, the button no longer appears and there is no way to enter the menu, I only get the screen that appears when I leave the power button pressed.
I’m trying the method of sliding my finger from right to left while turning it on with no results yet.
Please help!!!

Connect your watch to a PC, then press the Power button to enter the power down menu. Now you should have access to the watch storage via PC. Uninstall floating toucher.

Ok, I have done some Tests and I’m not sure that you can delete an app by using this way.
If you have closed all recent tasks (we warned to do this), I don’t see any way to solve your problem at the moment.

This is the video that I sent to the lemfo store in Aliexpress and they told me that I will send the watch back for guarantee but it is worth almost $ 30 = shipping dollars and I do not know if to send it, I sent them to say that if they could send me the files to I will flash it and repair it here without sending it, have they answer me.

Yes this has to be returned.
It is a screen connection issue with the FPC cable, inside the watch.
Flashing firmware will not make any difference. I can give you the firmware if you want to try it, but I have to warn you that it is not like flashing the other watches.
You need different tools, drivers and you have to hold the top button down as you connect the usb to your pc.

But as I said, that is a hardware issue that is normally caused by dropping the watch or similar… This makes the screen behave like your video.

I will ask them to clarify the return policy because it seems unfair to charge you for the return postage.
How long have you had the watch?
