I upgraded from the htc thunderbolt to the s4 and gave the thunderbolt to my 3 year old to play games on. Its been very useful to entertain and keep quite such as at a funeral. Up until about a week ago it connected to wifi so we could get fresh games but now it will not connect it says scanning, connecting, disconnecting and just does that over and over. I tried a factory reset which was dumb because now we dont have any games on it but still same issue happening. A friend has same phone and uses it just on wifi and has no issues. Also no issues with any other devices and have tried other wifi networks. Please if anyone has any ideas or solutions to fix this would be appreciated.
