I have just acquired an iPhone SE and it constantly drops connection to wifi. My old 4S stays connected as does my iPad mini, Macbook Air, Apple TV.
The SE, 4S and iPad are all on ios 9.3.1 and I have followed various suggestions to sort out the problem without success. Also Bluetooth in my car is almost unusable on the SE Help!!

Does it have a rattle if you shake the phone gently? My phone has a rattle noise as if something is loose inside the phone. It is also dropping wifi connection and my wifi are extremely slow compared to my other Apple devices. My camera is also blurry at times and has a ghosting effect at times
Below are some general suggestions for Wi-Fi issues. I suggest starting from the top and working down, maybe they will help....
1) Perform a Forced Restart: Hold down the Home and Wake/Sleep buttons at the same time for about 15-20 seconds until the Apple logo appears. Allow device to restart.
2) Reset Network Settings: Settings > General > Reset > Reset Network Settings. Rejoin the Network again.
3) Reboot Router/Modem: Unplug from power for 2 minutes and plug again. Update Router Firmware (check manufacturer’s support website for a newer FW). Also try different bands (2.4 GHz and 5 GHz) and different bandwidths (20 MHz recommended for the 2.4 band).
4) Change to Google's DNS: Settings > Wi-Fi > Click on the Network, Delete all numbers under DNS and enter 8.8.8.8 or alternatively 8.8.4.4
5) Disable device prioritization on the router if this feature is available.
6) Determine if other Wi-Fi devices on network are working well (other iOS devices, Macs, PCs).
7) Try device at another Network, i.e., neighbors’, public coffee house, etc.
8) Restore the Device (ask for additional for details if desired).
