hi
i just now googled it and the price in india is as given below
Micromax W900 Price: approx. Rs. 7500 /-(this is Indian rupees)

THe mobile is good but then I am quite irritated with Windows Mobile 6.1 OS in it. It has bugs and it is not thumb friendly. I have heard that 6.5 is better and its navigation is quite friendly too. I am eagerly looking for it.
I bought it @ Rs 7650 in Hyderabad.
The battery life is just good enough for touch screen.
With normal usage it should come properly for 2 days and on 3rd day some time it should go off.
Micromax guys seems to take more time to judge the customer reviews over this mobile as it was launches just 1 - 2 months ago.
As of now is there any good Windows Mobile 6.5 ROM available?
And do I need to reinstall some pre-installed apps like SPB Home and Sygic GPS for Map my India ?
Just let me know

i told tht
we need 6.1 Rom and we can thn DIY 6.5 out of it

Hi,
I have bought a W900 myself last week. It is a chinese phone at heart with the NEXPERIA 5209 board. I am quite technically challenged, but if anyone can help me with the instructions, I will try to extract the WM6.1 from my phone as I need to upgrade as well.
I wiped my phone clean and the applications like MapMyIndia, AdobeFlash n other stuff installed themselves again. So I think they have been included in the ROM itself and can be ported to the 6.5 ROM as well.

I had my iPhone 3G stolen and was looking for a touchscreen with wi-fi. This is the only phone less than 8k running a reputed OS with touch. I bought it for 7800 in Bangalore last week.
And the bloody GPS never works so the maps are of no use anyway.

How do I go into the flash mode on the W900?? I have tried holding down the volume, camera, Start button while powering up but it does not go into the flash mode. Starts straight up to the Windows icon.

The GPS works for sure. I have tested it in my mobile. Now there are few things which you should check.
1 - Do not try for GPS in office or @ home. The signals r not strong in closed area. Go out in open area and check for valid signals.
2 - The GPS system tries to connect to valid signal and if u see at least 4 - 5 sticks then it normally gets connected.
3 - Initially, before the connection it shows gray screen. the moment u get connected it changes to normal colorful screen and automatically locate ur current location.
4 - Once this is done then the route option gets enabled and u can select ur destination too.
5 - Once ur route is selected and u start moving in ur vehicle then it start prompting for ur directions ... Like "take left after 100 meters". ...
It is one good feature of this mobile ... Do try for it and let me also tell u that it takes a little while before it connects and locate ur self. Once that is done then it is quite fast and decently good... Best of luck.

U seem to have a probable solution. And I am sorry that i didn't get what u r trying to tell me. If u r asking me to check for ROMs then I have found few ROMs which are like tested on HTC mobiles and none r tested on micromax w900 or similar hardware.
And y do we need 6.1 ROM. I mean it is already there in my mobile.
At last y the hell did Microsoft complicate this simple upgrade ... I wish it was just upgrade button click...

What the seniors mean is that we gotta dump the 6.1 ROM already on our W900 so that they can use the same basic stuff that it has but upgrade the OS to WM6.5
Each phone has its own drivers n stuff for the mobo as in PCs. That is why they have a different section for each phone in the forums.

Thanks for the tip.... will try it for sure!! Were you able to activate the Sygic maps?? I tried to go to their website for activation but it asks for the product code.... n I haven't got one listed anywhere

Its a challenge to expect a Ferrari like experience from a Nano
Hi,
I just bought the Micromaxx W900 last week. Not to own but to experience it!
As i read above somebody has rightly said that it is a Chinese Phone, it has a Hisilicon-K3 (most of the phones which is are assembled in China like HTC have Hisilicon or HUAWEI processors) processor and CPU, of 460 MHz which is ok. It is also using Nexperia chipset, which also i would say OK.
But having said that they cam never be compared with Intels 620 MHz which used come with various PDA assembled in the EU.
I could not make much use of the GPS, i wonder why MapMyIndia chose to partner with them. I could not find any DRM version in the OS settings (Digital Rights Management), Doesn't seem to be a 3D touch flo. the Touch quality of a phone depends on two things - the OS and the Phones Touch quality, Unfortunately none of that supports it to have a great touch quality. there is no place to store the Stylus, you have to carry it separately in your pocket. The SPB Home's registration is also very funny, one needs the registration details for upgrade which has not been provided, at least i could not find the same anywhere in the kit.
I had some more to say but running out of time, would come back again.
regards,

Agree with everything said above EXCEPT for the stylus part. The stylus comes with a thread which you can pass through the holes at the top, just next to the headphone jack and let it hang around. I didn't find the stylus to be very comfortable in use so I've swapped it with a Nokia 5800 stylus thingy so I don't have to unscrew the stylus each time I wanna use it. Threading it thru the holes is another story, took me quite a while to do it and that too, with the help of a safety pin.

Hi,
I purchased w900 last sunday and from monday the Camera stopped working. The Battery life is so poor that if i just browse the mobile it takes around 5% of battery in 2-3 minutes. Really disappointed with this mobile. Won't recommend to anyone.

I read the dumping procedure for upgrading the ROM from 6.1 to 6.5 but i wasn't able to follow exactly what was written. I wasn't even able to locate the '.nbf' files etc. which are required for the upgrade. I need help in this context!
Thanks in advance...

My cam also stopped working so I went to Settings n did a Clean Boot. That fixed the issue for me temporarily....
found out later that Fring disabled the camera when installed. So am looking for a new IM app to stay online on GTalk using GPRS.

Considering Defy, a few questions.

Hi I'm considering the Motorola Defy, sim free from AmazonUK, but I have a few queries.
Are micro SDHC cards compatible with this phone? I know some devices can only use SD and not SDHC. Also is there a size limit for a memory card?
Is Android 2.2 confirmed by Motorola for official release?
Is it possible to selectively turn off 3g? I will be in Wifi zones most of the time I'm on the internet and don't have a data plan.
Can the flash be used as a flashlight? Alright this won't sway me but it could be useful.
What is MotoBlur? and do I need twitter/facebook to set it up or can I just use an email address?
I was also considering the HTC Desire however this phone seemed very similar but £100 cheaper, is there anything I would be desperatly missing? I know this has a slightly slower processor, but anything else.
Thanks I really appreciate you taking the time to read this.

Yes. No size limit.
Yes. Q2 of 2011
Yes.
Yes. download tesla LED from market.
Don't need twitter/facebook. Motoblur is a free service. You use your existing email and it let's you manage things from website including remote wipe.

Thanks disturkis4u.
Also just a couple more questions.
Is the model with white sides the US T-mobile branded model? and are the other models completely black?
Finally, does the OS affect the compatibility of certain apps ie. would some apps be for Android 2.2+ therefore not work on 2.1? Seeing as the Defy is currently behind the latest OS I wondered if app compatibility could be a problem especially if I decide to keep the Defy for quite a while.

white sides is the t-mobile version. Not sure of all black models.
There are some apps that are 2.2 only. From what i've seen those tend to be the google ones like gmail 2.2, youtube, chrome extension etc.

Wait dont buy it
People arround the world reported that the earspeaker becomes unusable after from 1 day to 3 weeks
Motorola Hasnt said anything
android-hilfe.de has polls and discusions, also the motorola support forums has examples

On the Motorola non-US site there are a lot of reports of the phone sounding like it's muted on a call and only speakerphone works. Most of these are from Germany, but they have had the phone the longest. I have seen a very few on the US site. I bought mine when it was first released in the US and so far have no issues. So far. I really like this phone and would rather have to get it fixed than get another phone because I don't like anything else out there... except the Nokia N8. Here's a link to the non-us Motorola Defy forum. Decide for yourself.
https://supportforums.motorola.com/...-android/defy_non_us?view=discussions&start=0

I sold my Htc Desire and got the Defy instead, havent looked back. Only thing I miss is the online rom kitchen over at Modaco, but I see a lot of devs getting the Defy, so I'm confident that we'll see a lot of custom Defy roms soon, or at least a lot of hacks and mods. I love that I no longer have to baby my phone (I tend to break things) and so my german Defy has the best in-call sound I've ever tried, way better than the Desire, whose speaker I broke (6 foot drop onto concrete, my bad) after 3 days.
Oh and Froyo is confirmed for O2 branded Defys from Germany for Q1 2011, so the 2.2 roms shouldn't be that far away. Rumors are also circling that China Mobile will start shipping Froyo-powered Defys "soon"...

That's not 100% true.
I have a Defy with white sides purchased from Carphone Warehouse in the UK - completely unlocked and un-branded.

I asked clove.co.uk about the colors and they said black'n'white were for telecoms only as far as they knew, and that there might be other color schemes eventually.. They carry the all black, that's what on it's way to me, so..
Hello, thank you for the enquiry. We think that there will be colour variants, most probably just black and white however it is also very likely that if this is the case then they will be network exclusives in the UK and only the Black version will be available for sale SIM free. Of course if this situation changes then we will list all variations on the website and offer current customers the choice.

At the end of the day if the earpiece goes I will send it back and get it replaced/repaired, it doesn't really concern me that out of thousands of phones sold a handful have developed faults

Hi, seeing as you had a Desire what are the main things I would be missing if I decided to go for the Defy, the only thing I can really tell is that the Defy has a slightly slower processor, how does this compare to the Desires?
Also I saw in a couple of online videos there is a bit of lag when using pinch to zoom can anyone tell me how bad this is?
Finally if in a wifi zone (which I am connected to eg. at home) when using the browser will the Defy automatically use wifi before mobile internet?
PS. thanks for the heads up on the earpiece problem I think I'll go for it anyway as I have been slightly put off by the Desire due to widespread random reboot issues and to me this is less of a problem (and seems less common), so if need be I'll get it repaired.
Thanks all.

The benchmarks have been pretty good on this phone. In real life I only occasionally notice a lag when pushing through the app drawer.
Wifi: assume you are on T-Mo USA and will have wifi calling app? If so it has a selection to favor wifi connect, or even wifi only. With wifi favored, mine choses wifi over 3G if the wifi signal is good. I suppose it's possible it may differ with different routers.

I can get a free upgrade from the Hero to the Defy. Is the camera a noticeable step up? How does it compare in low light? Is the flash any good?

Not that i have ever noticed. used it on the Cliq and never had an issue. Haven't had the defy long but I don't see any big drain by using Launcher Pro.

Do I have issues with my 10.1-2014?

Hi all, I have had my P600 since Christmas and it has been good. I am running ML1 firmware, no root. It shipped with MJ2.
I have noticed a couple of problems. Firstly, I have occasional bluetooth keyboard disconnects. They really infrequent but definitely occur. They just don't seem to be anywhere near as severe as people have been describing in other threads.
Secondly, this tablet just can't detect my 5GHz wifi connection. My Note II on the table next to it has no problems finding and using that connection. I am downloading MK1 firmware now to see if it is ML1 that is the problem, as I *think* that the tablet originally detected both 2.4 and 5GHz connections. I didn't really take note though. I have noticed this now mainly because I've been trying to turn wifi on and off to test what may be happening with bluetooth.
Thing is, I've never really had a good BT experience in my life, but I need to get this keyboard and a mouse working to use this tablet the way I intend to.
Is the 5GHz failure an ML1 thing, is there some other cause, or is it a hardware fault? Any tips?
Cheers,
Jason

Running ML1 as well. No comment on the BT keyboard since I haven't used mine enough yet, only for a few minutes here and there to test, not long time.
I have a dual band Asus RT AC-66U and I can use both my 2.4 and 5 Ghz networks. Only thing is that the 5 Ghz network gets poor reception from the tablet across my house (to be expected I suppose).

Thanks for the reply. It prompted me to look further and I realised it's a channels thing. Changed the channel on my router and the Note can see 5GHz now.
Silly me.

Someone has to find what's going on with bluetooth problem. It's very critical to be able to use this tablet with mouse and keyboard , especially bluetooth, as you can charge the tablet in the same time.

I agree. It is stressing me out. I feel a little trapped because a good test would be to install cleanrom 1.1, which at least one person has said fixed bluetooth, but I can't do that without sacrificing my warranty.
I am not even sure whether I have a hardware problem or bluetooth is just a dubious technology.

After reading a lot of reviews, there seems to be 2 major issues with the phone!

I badly wanna buy this phone asap but every time I check out some reviews over the internet across various sites, a lot of people have complained about rapid auto shutdowns and volte issues. Although, there are some who have been using this phone since more than 6 months and everything worked fine for them.
Is there any such issues on this phone like these people have mentioned? Cause both would be horrible for me. Shutdowns can be frustrating and if volte doesn't works properly, then Jio would be useless and I rely on it a lot as its my primary carrier!
Please let me know about the known issues of this phone as it would really help me to boost my confidence to buy it. And I literally cant wait to get my hands on it. Using something with a SD 820 would be like a dream come true!
Your opinions would be much appreciated.
Thank you!

So, according to you, the stock rom has issues and custom ones dont is it? I also wanted to ask you something. I heard from some people that we can still get the warranty for Z2 Plus even after flashing custom roms. Is it? And does these custom roms support volte? I need that the most.
What is your final opinion regarding this phone buddy? Is it worth buying?

About the warranty I don't know.
Volte works in my area
Zui OS is still under development
The fone is great for this money you can't get better one. The only thing for my is the glass back.... It's really slipperie... So you Ned to be carefull with the falls

Facing two very annoying issues.
1. The UI is pretty bad. It needs a custom ROM but that will void warranty so think about that.
2. When charging the touch goes bonkers. A slight touch would react very differently like the phone is broken.
I had VOLTE problem once, it left VOLTE band and didn't want to go back. Then after some changes in the APN didn't happen again.

Every Indian ROM should, I don't intend to unlock the bootloader until the warranty expires. I have a hunch that it will need to see the service center quite a few times. First and last LENOVO phone I would ever spent. Though having a Lenovo laptop I knew about Lenovo quality but couldn't resist the discount now the return window is closed too, regrets.

I don't know who told you that?
I had a lot of android phones since original Samsung Galaxy, LG, Sony, HTC, Amazon phone, Nexus 4-5...
So I find ZUI (China version 2.5.334 ST) snappy and one of the most stable ROMs I ever used...
About the issues, since there is no top developers involved in ROM development for ZUK 2 it seems to me that after unlocking bootloader and messing with various versions of ROMs even flashing India ROM on China based ZUK can cause some serious issues...
It is your call whether to buy or not...only thing I don't like is mediocre brightness of the display...

ZUI is the worst ROM I have ever seen. Period.

What is the difference between XT1794 & XT1797?

As a owner of the XT1797 .. I have noticed issues with 4G / 3G with poor signal with dual or single sim inside the phone this seems to be a common problem with this G5S series after doing some research via google .. am also hoping with Android Oreo they may have solved this problem by then .. overall nice phone i like it a lot .. but can''t really open the phone yet due to being so new on the market and just now i have the bootloader is open and am waiting for developers to start making mods .

Owner of xt1797 here too... It has Lte Cat.4, so maximum download speed is 150Mbps and 50Mbps for upload. Tested on both my iPhone6s and this phone, getting 85Mbps download on my 6s but only 35Mbps on this phone... Wondering why...
