It can be something wrong with the power button

There is four simple step to format . just follow it. remember if ur phone memory have important data so u should be aware that i will erase ur data.but there is no other methods so.. 1- Power down your device. Before you begin the reset procedure, you will need to completely power your device off. If it is frozen, you can pull the battery out to turn it off. 2- Press and hold the recovery buttons. The buttons vary from device to device, so you may need to look up the instructions for your particular phone. You will need to press and hold the buttons for a few seconds. Some of the more common button combinations include:

• Volume Up + Home + Power
• Volume Down + Power
• Home + Power
• If none of the above work, do a web search for your phone's model plus "recovery mode".
• 3-
• Select Factory Reset. Once the recovery menu opens, you can navigate the menu with the volume buttons. You may need to open the Recovery menu to find the Factory Reset mode. Use the Power button, some models use the camera button, to select your menu options.

I remember reading somewhere about an issue with so called off brand phones(Non-Flagship)... as im in the same boat(Using Cubot Brand) and talking with my service provider today. they stated my phone isnt on the list or compatable with the at&t network anymore(atleast the calling part of it) you should still be able to use data & text. Lucky i already have a third party app for a 2nd phone and also use google voice, both of which let me make calls using my data. and if i need to contact someone i can either send a voice/text message as normal.I have read somewhere that i believe blu is trying to get onto the att network. So hopefully they do because ill just switch back sense they are a good phone company. Hope this info helps.:Edit: Even if it is 4g LTE, also spoke with a friend who has a 5g non-flagship whos carrier uses att and she isnt able to make calls from the phone but the speeds are still there. So hopefully something gets fixed because I believe this is some B.S. to lock us out because we dont want to pay for a iphone or samsung

call your cell phone provider for help using a good phone,

Internet works because it uses wifi. Calls use your provider, they have cut you off. Also, if you use another company SIM and if they own the phone on a 2 year contract, they will lock you out with a PUK Lock. Phone them on another phone, or go and visit them. https://www.google.com/search?q=Blu+V90 ..

try swipe down from top and pushing setting button then accessibility menu. is it set up to unlock by voice or if on you, if not try to access google play from a different device to check settings or reset

Go into Setting - Accessibility and uncheck 'Visually Impaired' or 'Text to Speech'. Actually, Blue call it 'Talkback'. See the video. https://www.google.com/search?q=blu+phone+has+started+repeating+out+loud+everything ..

The blank screen while charging is characteristic of cell phones in general.

heHello, Two ways you can get back yourdeleted messages from the phone.

1)From the service provider. WHAT YOU NEDD TO DO TO GET BACK THE MESSAGE FROM THEM IS TO CALL ON THEM FROM THE CUSMER CARE CENTER. 2)From the other side that the message was send from. Thanks.

I think the battery is dead or software problem.To check try to keep charger connected and try to reboot if not then contact the local mobile repairing vendor...

check with provider for unlock or phone has damages hardware

I don't think so, you only lose the info on your cell if you make a factory reset. If you can make a back up with an app.

One or more of your keys may be slightly pushed in causing the phone to blink and the other keys not function properly. Turn off your phone, remove battery and clean your phone keys with a qtip or a soft wipe. Be sure to not soak where solution is dripping, that will cause further damage to your phone. you want to dampen the qtip or soft wipe and gently clean the keys. As you are cleaning the keys you may notice by touch (not visually) one or more keys may be pushed in. Genlty rub the part of the key pushed until it releases. Continue to clean all the keys and the outer part of the phone itself. Replace the battery, turn on phone. Hopefully this resolves the problem.

change the screen. ask the hacker to help you see if you can change your code to a new code.

take it to a phone company where you bought the phone or you could tell them someone gave it to you. they can help you with it.

Your phone may be set for wifi calls. If you've turned off your wifi then your phone goes into airplane mode. Have you tried disabling airplane mode through settings? You could also disable wifi calling in settings. Hope this helps

off the phone and remove the battery for 10 minus then fix it back and on it it will be okay.

Try factory reset if don't really remember the password
