I bought my ASHA 311 frim slot but I notice the following abnormalities after about 3weeks.
1. Thouch screen started seizing, at times even stop for more than 5hours.
2. The phone does suddenly off and on back by itself several times.
3. The network does disappear for very long time and reappear back.
Then I went to the Nokia store and I met more than 5people complaining for the same reason.
The phone was later changed under warranty and I am still experiencing the same abnormality with the second phone.
I now want to ask my fellow nairalanders that are using the same brand of phone if you are experiencing the same thing
