Motorola teased eager customers on Thursday leaking more details on its upcoming Droid Bionic phone.

The company said the phone is still on track to come in the summer after incessant delays.

The Schaumburg, Ill.-based company was responding to a Tweet from an angry customer ho who threatened to buy Samsung's Droid Charge if the company didn't say when the Droid Bionic would be released.

Motorola, which delayed the launch of the highly-anticipated phone in April, causing customer frustration, added that it was working on new enhancements to the phone after receiving compelling feedback.

The delays were caused by operational mishaps, analysts say, that is creating a hole a number of competitors are taking advantage of.

Coupled with the delay of the Apple iPhone 5, the real winner has been Taiwanese competitor HTC.

The delay was due to network interaction problems with MMI's protocol stack, but in general MMI is executing well and should continue to do so, Motorola CEO Sanjay Jha said earlier this month.

The Droid Bionic will feature hardware from Texas Instruments and feature 4G connectivity, but has bee severely delayed from due to operational problems at Motorola, analyst said.

Apple is expected to release its next-generation iPhone in the fall, so there is still time for Motorola to hit its summer release date and give the Bionic a head start.
