Apple may have agreed with Google's Motorola Mobility to drop lawsuits against each other, but another lawsuit awaits the Cupertino-based tech giant after a California woman filed a lawsuit claiming Apple failed to delivery texts to her Samsung Galaxy 5 which runs on rival OS Android.

Adrienne Moore accused Apple's iMessage system for iPhone halted sending text message to her Android phone.

It seems Moore is not alone in her predicament. Business Insider reports that other former iPhone users who ditched their units in favour of Android or BlackBerry phones experienced the same problems. Some of them, such as a female Verizon sales representative, lost sales commissions because of Apple's action.

Other former Apple complained that they lost not only money but also suffered broken relationships because their spouses, friends or relatives thought they ignore their SMS.

Another former iPhone user, Katie Becke, claimed she loses $500 per sale of car due to text messages not received. Alexis de Belloy shared that because of SMS that are not sent, he experienced misunderstanding with his wife whom he thought was ignoring his messages.

Business Insider said the other affected former Apple users also plan to file lawsuits against the tech giant.

Apple has instruction on its customer support page how to turn off iMessage so other iPhone users would not continue sending message to the iMessage address no longer used. Apple said the texts are stuck in the iMessage box trying to find the old, inactive iMessage address.

Instead of turning off iMessage prior to switching to an Android phone which often doesn't work, some former Apple users believe their phone number from iCloud must be deleted. But others think the flaw in the iMessage is Apple's way of punishing former users for leaving the iOS system.

Apple introduced the iMessage service in 2011 by letting iPhone users communicate with one another over data and Wi-Fi rather than their respective telecom network, allowing transmission of messages faster that are not counted in the cell plan.

Justin Frazier reverted to his old iPhone and returned the Galaxy S5 he bought because despite turning off all his Apple accounts before switching to an Android-run unit, waited for 10 days to see if the issue would be solved but was only frustrated. He said, "I feel this is something the Apple developers could develop in a heartbeat, but are in no rush as it benefits the company."

However, an Apple tech support specialist told former Lifehacker Editor in Chief Adam Pash that Apple is aware of the problem but "is apparently clueless as how to fix it."
