[Q] Waterproof Information topic

Hello, I had this smartphone for a month, but I read on the internet that, when the Xperia Z2 is submerged under water, the camera becomes blurred.
I want to know if this problem has come on all devices, or only on bad product. I followed the tutorial to find if my device is isolated pressure sensor (the number changes when I press my device).
So someone used Z2 underwater? How did you find problems after use?

[Q] (Google Play Store) Error retrieving information from server [RPC:S-7 :AEC-7] topic

Greetings,

I had some issues uninstalling xposed on my HTC One M8 that was recently updated to lollipop so I reverted back to a stock lollipop rom directly from Telus. Every time I try and download an app from the Play Store I get the following message.
"nameofapp" could not be downloaded due to an error. (Error retrieving information from server. [RPC:S-7 :AEC-7])

This is what I have tried so far:
- Clear cache on Google Play Services (Framework) and Google Play Store
- removed update from Google Play Store
- updated Play Store manually to newest APK
- rebooted in between these steps
- removed Google Account + cleared cache + all data for all Google Apps and services

Sometimes when I reboot it will let me update or download 1-3 apps, then it will just bring back that error. I'm at a loss as to what I should try as googling this error brings up the same solutions every single time. Other then this issue the phone itself appears to be functioning properly. My phone is unlocked and rooted but I do not have xposed or any other custom mods running. I'm also using the latest version of TWRP. I have also noticed that sometimes when I disconnect from wifi and attempt to download from 4G the download actually goes through. Not exactly a solution as I have limited data available to me. Any ideas?

[Q] Jiayu S3 contradictory information? Help please topic

So this is one of the new chinese flagship smartphones thats suposed to be pretty good.

i've read in many sites that this phone 3g support its only for the 2100 band, but as you might imagine, most of them are a copy paste of somewhere.

This guy in aliexpress has SS of the actual phone in engeniering mode where he claims as many other sellers (not the majority but many) that the phone does suport 850 mhz WCDMA, and the part that confuses me even more is that i can see in one of the SS that it also has the option of GSM on 850 mhz, but in the description part in the bottom ,it says it doesnt suport 2g in 850mhz? just in 3 other bands.

es.aliexpress.com/store/product/JIAYU-S3-FDD-LTE-4G-WCDMA-MT6752-Octa-Core-1-7Ghz-2GB-3G-RAM-5-5/321958_32247923121.html

So as you can see from his post, the SS are original and made by his store personally he has all the signs and stuff suposdly proving those are boxes full of those phones ready for sell aswell as the SS of the phone itself.

Im interested in this because in live in south america now, and 2 of the main cellphone companies here use 850mhz as 2g and 3g bands, and its a great phone and i'd like to purchase it in the case it would be posible to use it here.

So any smart ppl that knows more about this subject than me, and can help me out a little more on this please? :confused::confused::confused:
