Have not had time to downgrade firmware to previous version. Currently i tried to switch from my home's 5ghz wifi to 2.4ghz wifi network. Its better now.
While i might not say for sure, but being on 2.4ghz wifi network is giving me better experience for now. Could be some issue with the latest firmware & 5ghz wifi network.
On 4g data i didnt experience such issues.
Very significantly can tell the difference. Previously no matter im on 4g or 5ghz wifi, images from twitter, facebook and instagram loads very fast unlike now on 5ghz network i see a lot of blank spaces due to the pics not loading fast enough.
Another problem noticed to have with this issue is, when downloading of pictures sent from others via whatsapp, usual 4g / wifi will dl the picture almost instantly. With this issue, after u tap to download the pic, there will be this circle that spins for quite some time. Afterwards shows a little progress with slight green curved bar over the circumference of the circular dl icon. All in all, takes a ridiculously amount of time to dl pics which definitely isnt normal.
