It helped a bit for some time. The problem I have now is that wifi works fibe with safari, but when i ipen an app like instagram, facebook or others the phone is losing connection for some reason. Before, the problem happened everywhere including safari.
I hope apple releases a new update soon and tht this priblem gets solved. Else i'll have to look for an android phone. From all I heard from friends and internet they have a more stable connection in general than ios devices.
