Hi all
I tried going to a Lollipop ROM on my S2 but I only managed to change the recovery, the ROM didn't work (boot loop) so I used ODIN to revert back to the stock ROM (i9100XWLSW) wiped both the data and dalvik cache. I did also have Kingroot installed during all this and I installed it again after flashing the stock ROM but I've since removed that too with another write of the stock ROM via ODIN.
The problem I'm having now is Whatsapp and other apps won't actually do anything if the device is asleep. The WiFi appears to be connected, logo is present at the top if i wake the device but it takes about 10 - 30 seconds of being inside an app (such as Whatsapp) for anything to happen. I'm not sure if this is a WiFi issue or some sort of app issue across the board? I woke up today at 9am checked my phone there was nothing on it. It was only at 10:30am when I went to send a Whatsapp message to someone and opened the app manually that i had messages come in from 8am that morning. I also use Whatsapp Web and some times it won't connect to the phone via WiFi even if the device is awake. I have to reboot and try again. Although if it's connected via Whatsapp Web and asleep messages come in no problem at all both on the PC and the phone??!!!!
It's doing it constantly now, at the start it was touch and go but now it's all the time i have to constantly check the app for messages to come in. This happens on other apps too.
What's going on? Have i damaged my device some how from the flashing process? I'm pretty familiar with ODIN as I used to flash my old Galaxy Apollo all the time but never had this problem.
I was going to get a new phone but I actually really like my S2 and it actually keeps up with most of the phones in my price range and in some cases (camera, AMOLED screen, storage, sometimes RAM) it is better than the new stuff!
Any idea's please?
