Today I received an answer from DEXP to my question. Although he himself had previously solved the problem by installing additional memory.

>Employee: Expert Valery
>Answer text: Good afternoon. If any message does not fit completely on the screen, then nothing. The message “Error accessing ...” has 2 ending options: 1) to the file 2) to the SIM card If you get this error regularly, you need to hand over the phone for verification to the SC (it is advisable to hand over the memory / SIM card along with the card) on which the error occurs). The addresses of the SC of your city can be found here -https://dexp.club/service-centers/Regards, DEXP Specialist.

I like the phone in general.

And who knows, is it possible to install Java applications on this phone? Does he support?

I also noticed in it the most important drawback is that suddenly the network loses and people can’t get through to me !!! Only reboot helps.

Something on it firmware is not visiblehttp://ftp.dexp.club/Phones/
The last one on Z3. Maybe it would be possible to pick something
I’m thinking of buying a mother in DR

The phone is not bad. For your money (899 rubles). It's definitely worth it.
The reader is clear. The display responds well. It works clearly.
I’m basically a big fan of digging around ... And that’s what I was able to dig up
The processor is defined as Mediatek. Stupidly in D.U. Windows. When connecting a COM port.
Out of the ordinary. Support MRE. * vxp (China Java). But only up to 100kb. I checked and downloaded a couple of games and an FB messenger for the sake of interest. It starts.
BUT !!! It seems there is a GPRS module. But software support does not seem to be implemented.
By the way. If anyone comes across its original Firmware. Throw it, I will be grateful: thank_you:. I'll try to dig up something else

I just wanted to buy, and he is already 1499 re)

I bought such a phone for 999 rubles. a month ago, later in the CSN campaign for 899 rubles. An interesting copy of the phone. The firmware is obviously damp, so to speak, it is slightly unfinished to a convenient use by the consumer. In short, the first copy first sent an SMS to India (I suspect that the old SIM card from Beeline was infected from another phone), and nothing was saved in the sent messages, BUT the old SIM card worked normally in the first slot and in the second. I ran into the beeline and replaced the SIM with a new one, changing the subscriber number. Having inserted a new SIM card into the unit, he began to issue “access error .....” in the first SIM card slot, moved it to the second slot, first the SIM worked, then when trying to get somewhere, it issued a female voice “inaccessible blah blah service blah. " The beeline operator cut off all the phones, replaced the new SIM card with a new one again, but everything was in order with the SIM card and services. I changed the device to the same. Bottom line: the first slot also writes an access error, the second slot is working for now. By the way, if you insert the old SIM card of another operator (for example, body 2) into the first slot, then it will work as it should. Somewhere on the Internet, I read that there may be incompatibility of a new model's SIM card (firmware) with the firmware of the phone slot. I hope I wrote well))

So ))
I carefully disassembled this device. For the sake of interest (I do not care about the guarantee, it's not the phone that you can take there :))
Found such contacts on the testpoint diagram

dm --- = Download manager ????

dp --- = ???

pwr --- = power hike

boot --- = bootloader

vchg --- = contact next to the USB connector, most likely memory control

vbat - === next to the battery contactor

gnd - === well this is earth.

Explain someone. What kind of contacts I did not sign? And correct if you made a mistake in the marking.
And most importantly, what contacts of the testpoint should I close to download Preloader?
I'll try to remove the full via droidtools.
Suddenly someone will come in handy later. Once in the OFF site, they are in no hurry to upload the firmware

I tried to install games with this extension and no more than 100Kb, for some reason there was only one game about the Teddy bear and it was installed in Chinese .... Then I deleted it, but there were several icons on the desktop in the form of several windows.

Well, what about success with backup?
This little miscarriage infuriates my mother: rofl:
I would like to pick out the firmware as someone

Finally, I got the phone in my hands, presented it ... I begin testing ("Flight" mode, without a SIM card).

1) Screen. Bright, horizontal viewing angles (phone in portrait orientation) are good, vertically predictably poor. The normal brightness level is the 2nd (by setting), all in all there are 5 of them ... The 1st is also suitable for reading.

2) Mount for strap. Now it can be met extremely rarely. Although it is not very convenient here, but, most importantly, it is.

3) Battery, power consumption. Very good characteristics: continuous video playback for more than 10 (!) Hours with a brightness level of 2 VA. MTK makes cost-effective processors.

4) Charge indicator. Four non-linear states: full, half, quarter, red stick. To put it mildly, not really.

5) USB. Unfortunately, it’s not very fast, the write speed is only about 700 KB / s; and the microSD slot is not so convenient to use a card reader.

6) The buttons below the screen are not touch-sensitive, but quite “push-button”.

7) Sound. Loud, especially in the audio player mode. For higher volume, you need to substitute, for example, the palm of your hand.

8) Communication. I did not check and I am not going to. I already have enough phones. For example, Sony Ericsson Cedar ...

9) Radio. Antenna - headphone wire. The receiver is not bad, sensitivity is normal and the sound is loud, but not stereo. And the duration of continuous operation from a freshly charged battery is one day (!).

10) Interface. The interface, of course, is original, but I'm afraid not for everyone :). Apparently, the lack of memory affected, although today it is strange to talk about it. Folders are only supported in My Files. In all other "menu items" (except, perhaps, the audio player) they are either not visible or are processed incorrectly. The virtual keyboard ("telephone") works clearly, it is convenient to use.

11) Audio player. The sound is not so bad, at least loud :). .Wma files are not supported, apparently only .mp3. Of course, they are too clever with playlists: you must first "add" files, including from subfolders. Audiobooks seem to play correctly. For the current playlist, the current file and position are saved.

12) Gallery. Thumbnails are shown for pictures. Colors are very authentic. I did not check the maximum resolution, but 6 MP is displayed normally.

13) Video player, if you do not take into account the interface, is not bad. "Eats" AVI and MP4 files (both with MPEG4 format), but the resolution should be no more than 320x240, which is solved by converting the file. The current file and viewing location are not saved (!).

14) E-books. The implementation is so-so. It is checked by search, a format - only TXT. They completely refused to try to practice word breaks, and even more so to turn them off. The small print is too small, and the average is too big. Line spacing is large in both cases. The colors of the letters and background are not adjustable. When reading, time and charge are not shown. The page number is displayed only when you touch the screen. When changing the font, the file is opened again (more carefully), auto-scrolling is disabled when the book is opened, manual scrolling - either with the volume buttons or scrolling around the screen. Read at the 2nd level of brightness can be practically in direct sunlight (tested in the spring blinding sun). The current book is not saved, but the current page in it is yes.

Well, everything seems to be.

Cool! How to sit in the car, turn the buttons, pedal, pat the glove compartment, but do not start and wherever to go. Nafik is necessary, I have UAZ-Patriot: rofl:

BV4000,
Read my previous posts on this topic and try to understand a simple thing: I need a player, and there is practically no offer on the market now. So I grabbed onto this phone. And SE Cedar is much more convenient as a telephone, although it’s not bad as a player, and it’s not a dummy camera, it’s shot a whole gallery when it’s in the hospital (there is something to shoot in Akademgorodok). In addition, you should not waste your phone’s battery power in vain - it will come in handy for communication, and the player will be discharged - and yes. Are you see? :)

Adding to the review:
Blue navel, alarm clock, calendar. Everything is quite functional and quite convenient to use.

Link to the original firmware:

Tell me, please, is there a camera there? The site is not listed, but here in the discussions I see. And if so, how simple is it? Can I take text from a sheet?

Yes there is. I tried it, it’s badly smeared, the current if I try to try somehow I don’t know anymore.

I bought this device: rolleyes :. climbed in it :). music here without an equalizer is horror, already ears hurt. in a player with an equalizer more or less. The equalizer is called the audio effect in the options, there are two modes for me the most norms are normal and bass (low frequencies). and looked for vpx applications hereCatalog of games and software for Chinese phonesthere not only applications under 100kb go, some do not go, some go.

So all the same, how is it with the support of real JAVA? Can you try to launch any 240h320 touch toys in jar format?

For example, here from this topicTouchscreen Java Games

no nezya i got through

It’s sad. By the way, he is now in the CSN with a 53% discount, it costs 699 rubles.
