  • I am using huawei u8520 and i am facing a problem that a few keys like "delete" and "L" are not working on keyboard. How to resolve the issue? please do reply. I am really very worried about my set.

  • My Huawei dual sim phone (U8520) gives a problem. It says my memory is full and I cant receive incoming messages any more. I have deleted all email, some apps, and all messages to get space on the memory. Although things are deleted, the overview is still the same in the phone storage. What should I do?

  • Does it ask's security code to unlock?

  • Dual active SIM worked great. Used one for work and one for private and only carried one phone. Had a few problems with phone turning itself off. Left and right margins of touch screen died 3 months after warranty.

  • I had this phone before, problem is the phone gets hot easily and sometimes reset automatically. This phone is excellent in features however due to power problem, this phone loses points. Reliability is a thumbs down. other than that a great phone to use.

  • Have read the booklet that came with phone but?? - does anyone know how to change the time setting

  • Hello, does anyone know if the connection behind the grommet, bottom left of battery with cover off, is for a patch lead to an external antenna? If so what size plug is it? Thanks Syd

  • no its not normal it is faulty

  • Does anyone know how to upgrade Android 2.2.2 to higher version for this mobile phone? How Skype video calling works, I can only use it for skype voice call?

  • so good & smart my u8230 mobil set

  • Yes it is normal that it turns of by itself don't worry i got one too.

  • good device

  • I bought one Huawei U8520 Duplex mobile phone,it is good but not working for other SIM except TATA DOCOMO. Pls tell us can it work for all other SIM Card through customer care!

  • i got one,it´s the my first one huawei..can you tell mi if it´s normal the reinitiation of the sistem several times for day??thanks

  • i saw it is 149 Eur in Portugal, is this price good?

  • why u not wright the cost of handset

  • is this the cloudfone ice + lock on globe telecom in the philippines? does it have mobile TV?

  • Thanks for the advice on wlan and rebooting. I've the same experience, left wlan off and the rebooting stopped , for 2 days now. At under $150 from Allphones in Australia it's still remarkable value in my opinion (as a first time Android user).

  • To use a Data connection, you need to create an Access point (using the settings supplied from your carrier) - select Menu > Settings > Wireless & networks > Mobile networks > SIM 1 > GSM/UMTS Options > Access Point Names. The minimum information required is APN, username & password and set the APN type to Internet or Default. This device supports 2 SIMs but only SIM1 supports 3G (WCDMA) so make sure your SIM is in SIM1 slot for a faster connection

  • go to settings->Wireless & network settings->Mobile networks->SIM1->(Check Data enabled)->GSM/UMTS Options->Access Point Names->press on the options button on the lower left of the screen->new APN-> put in ur carrier settings-> save and ur done

  • Looking for help... I have this phone in the UK - but I cannot make a data connection because it will not load the GPRS settings from the SIM card. I can't find any way of entering the details - which my carrier eventually supplied - manually. Does anyone have any idea how this could be done?

  • There is no need to root it to use USB Tethering or as Wifi Hotspot. Bought a second hand one at an unbelievable price from a local store and it works fine. The only problem I face till now is the memory as large apps don't work. This includes Facebook app, G+, etc.

  • I bought the U8520 Deuce from allphones last year. It is far from perfect but works surprisingly well for such poor specs. It occasionally locks up and needs to be reset. The camera quality is poor and Huawei support is woeful! Despite its faults, it does exactly as advertised, only 98% of the time. WiFi Hotspot is a great feature and does not need to be rooted first. The Android os is nice to use and the market has mostly everything I had on my previous iPhone. Overall, I'm happy to continue using it until a high spec smartphone with dual sim arrivals on the market.

  • Skype videocall working?

  • Was very interested in this phone until read manual & discovered that it cannot create either a wifi hotspot or a tethered internet connection, unless you root it. :( For your info.

  • Is selling with no network locks in Australia for $AUD199=$US195 @ dse.com.au It doesn't have much RAM so how well will it work?

  • I want this phone.How can i get this phone as i am from Egypt and how much does it cost($)? I am waiting for your replay. Thanks

  • I have had this phone for over a month now, and I have some significant facts that I believe are worth sharing with the community. First, here is a brief summary of where and how I use the phone (some people might want to use it differently): - the phone works as expected (dual sim standby) - I've used it in Portugal, where I bought it, and I'm currently using it in the US (where I live). I have had my Portuguese sim card (roaming) and my AT&T sim working both here and in Portugal. Quad-band seems to be working just fine. Faults/Defects: 1)It is not possible to configure different ringtones based on sim card (it is however possible to assign different ringtones to different contacts). 2)About the unexpected reboots: when you leave the wi-fi on for a long time the phone can reboot unexpectedly (has happened to me a couple of times in the beginning). I no longer leave the wi-fi on and never I've seen my phone reboot again, current uptime 300 hours. I do use wlan on occasion (switch it on, use the web, and then switch off). I would argue that this is a decent phone for the price, however... 3) my major complaint is the following: recently contacted the provider that sold me the phone (Optimus) questioning them about when to expect a software update (2.2.2 -> 2.3), to which they replied saying "it will not be possible to upgrade the phone", furthermore adding the following enigmatic sentence "Huawei will not make software 2.3 available". I'm not sure if there is some sort of fight between the manufacturer and my service provider, but I'm certainly not happy about this. This is completely unacceptable, and I'm actually considering swapping both (manufacturer and provider). The Samsung Galaxy Y DUOS should be popping out this February, and it seems very similar to this Huawei model. Hope you find this review useful

  • I have been using the U8520, and it has not rebooted for once. mine is working perfectly well. i recommend this model to avoid carrying two mobile phones

  • So where's the link for the updated software (assuming it exists at all) can't find it anywhere out there, without an update I would not recommend buying this phone as it constantly reboots and the Tech Support is non existant saying they are aware of the problem and are working on a solution .... 4 months later - we're still working on it.

  • I suggest to update the software to latest version by MicroSD (you should know how to do it...download from Huawei website or ask help from operator ), my restart problem has solved, aha

  • This model does not know. But accer DX 900 and B 7722 samsung but no letter i, to be occupying one of the other networks give Call-waiting signal and beeps sound through oscultador because it has two antennas, while most do not, only one is if this model. On the other hand mobile phones with two integrated antennas have a high power consumption, providing only for a day or so in 2G if 3G, or one day. The difference is this. Almerindo Abreu - Portugal

  • For all of you who has restarting problem; turn the wi-fi off if you ain't using it, and it won't restart anymore... Mine was restarting too, but when i turn wi-fi off when not using the phone, it doesn't do it anymore...

  • also the same problem: random restart. my was buyed in optimus. now another problem: can´t send mms in both sim card. Now I have a dead mobile phone because he don´t start.

  • Love the phone but I confirm the random restarts, this is my second and with the same problem. Gonna ask for money back

  • when is this phone arriving in kenya,and how much it gon'be?

  • Do you have any problem like random restarts? I buy mine in optimus and he randomly restart...:(

  • I have the same problem. Did you find any fix?

  • Good looks, sounds good, good touch sensitivity, but major problem... This phone keeps rebooting randomly and i don't know why. When i searched the net for support i found several other users with the same issue and no resolution. Today i whent to the mobile shop. I've got a replacement, but, 1.5hours later... The same random rebooting! Too Bad. i'm going to get my money back.

  • Yes, this fone is now in Nigeria check e.tel Thanks

  • this problem is in china off china mobile it want u always charge this is so bad from china mobile

  • quoted "When you are in a call using one SIM card, the other SIM card is out of service and you cannot use it to receive other calls." p.19 Phone Manual

  • Is this available in srilanka? How much its Price?

  • Fine specifications but one thing left out, light for the camera, you not take good pictures at night.

  • i hope it will

  • The above specs say it's a "Dual SIM (Dual stand-by)". Didn't you see it? :)

  • Will this device come to saudi arabia?

  • The phone seems to be close to Gigabyte G-Smart 1310/1345 and ViewSonic V350 regarding the specs. An important question is whether the other SIM remains active during phone calls and/or browsing the net? Current dual SIM Androids on the market are dual standby, however put the other SIM into inactive state while in use. Anyone knows the answer?
