BLU Dash 3.5 - User Reviews

  • This phone has a special place in my heart, my dad found it lying in the street, he brought it home and gifted to me, even though it was a piece of shit it was my first smartphone and I enjoyed playing some emulators and watching youtube videos. The camera didn't even work, the screen was all shattered (but still worked) and it was slow as fuck, but for a 10 yo kid like me, it was great.

  • So may I ask how did you switch your storage from internal to external?

  • So may I ask how did you switch your storage from internal to external?

  • Limit is 16external, that's why 32 didn't work

  • This is a cheap phone, a piece of s***. But it works, you can use WhatsApp, YouTube, Google Translator, 3 common dictionaries, a Phonetic App, facebook Lite, and a game like Geometry Dash, but that's all. Don't root it ! You're gonna make it worse! Don't waste your money on this!

  • i have blue dash 3.5Ce can it connect 3G network

  • Disgusting. No storage space for anything other than the pre-installs, and even with an SD card it remains to be useless. The camera is absolutely pathetic as well. At least it can make calls...

  • Same here. Told the board is gone. Not even 3 months in use

  • My first blu and I'm disappointed. An hour after purchasing phone goes blank...wont turn on. If plug in charger it shows battery charging for about 5 seconds then goes powerless and wont turn back on.

  • Absolutely AWFUL! Zero internal memory, and still does nothing even with a 32GB SD card inserted. Not the phone for the person who likes to download the average applications (facebook, etc) because it will not work.

  • I am a BLU 3.5 II phone, the touch is blocked, how I can resolve this problem?

  • Im not able to see pictures on fb n google n the constant msg ofinsuffient space why?

  • this phone can't accept call forwarding. that's fail function

  • My phone says message memory full but I have no messages on my phone because i deleted all tand I'm not receiveing any message. Can someone please help me, tell me what to do?

  • i want to get my phone screen fixed cause it is now frozen that i can not unlock it call,text or anything at all need help

  • go to key pad and hold down enter on keypad until u see a smiley face then click on it. And there u see emoji cons

  • I have this phone, the Android is 2.3.5 not 4.2.

  • How can I put a game on this phone-- cannot seem to put a game

  • Your specs are wrong. My dash 3.5 has only 169Mb internal memory. except the factory installed apps,(none of which can be uninstalled) I managed to install 4!!! more apps, 2Newsreaders, one weatherforecast and one game with 10Mb. and I cannot use it as a phone, because the Battery(original, 1 week old) empties in about 5 hours. So people, don´t do it. Rather buy any other smartphone, this one is trash

  • It´s so great.

  • Sorry I ment I think the camera is pretty good

  • I think thd camera is pretty good

  • WiFi-good, Tethering-good, Snd/Vid audio Quality-v-good, Generally Rugged. Picture Quality-Poor, Video Quality: v-poor, Icons jump all over the f--kn Place, All my phone contacts disappears, time display suddenly changed, Simcard may move out of position, and system will not boot. You be the Judge. If any Suggestions email me: [email protected]

  • Let me chime in here. I had this phone for 6 months. An absolute piece of trash. Started out OK but quickly developed speed problems. Candy Crush nearly seizing for example. Horrible performance with any non-mobile web page. I really wanted to smash this thing with a hammer the day I turned it in to my service provider. Replaced it with an LG-70 which costs the same and is an AWESOME phone. Don't buy it. It's not worth 25 cents.

  • You need to setup your APN settings on your phone to access you mobile data network with your carrier. You can contact BLU for a helpful programming guide to help you set up the APN settings, but you will still need to contact your service provider. BLU tech support email address is [email protected].

  • There's a real big problem with the microphone. I bought one last month and everyone that I've called told me that call quality was horrible. It was like the mic captures every single background noise of the surrounding. I went to the service centre to get a new one and the problem was the same. I went to the service centre for the third time and they flashed the phone, telling me it was a software issue. Unfortunately same problem arises again. Went to the service centre for the fourth time to get my money back.
