I have LG Optimus L7 (P705) running 4.0.3. I am using the stock Messaging. Yesterday I received a bunch of messages, and before its notification could pop-up, I deleted one of it. Now, I dont have any unread messages, still the count shows 1. I tried installing Go-SMS pro, but even it shows the unread count of 1. I rebooted the phone, deleted the messaging data, without any results.
Then, I installed SMS Backup & Restore, backed up all the messages, and then deleted all, still the count was showing 1, when there were no messages. Then, I restored all the messages using the same software and was surprised to find that there was 1 unread message in it but now the count had increased to 2. When I deleted that unread message, again the count came back to 1.
Please let me know how to fix this problem.
