Flash phone s23
Cindy -
Hello, I bought an S23 Ultra phone on Aliexpress (given the price, I didn't expect to have such a powerhouse) and I would like to make it a little faster, improve its battery performance, and especially get Google Play Protect certification. My problem is that I don't know where to start; I still have a lot to learn. Could someone help me? Don't hesitate to ask if you need information about the software already installed? Thank you in advance for your help.

Hello,
The question is somewhat unclear.
The purchase price does not affect the performance of the phone, which is not known to be that bad.
If the price of a new phone is slashed, assuming it hasn't been stolen, it's often because it's meant for a foreign market, particularly China, and thus lacks Google Play.
You can install it manually.

That said, the effectiveness of an Android antivirus is not proven, and if there were to be one, Play Protect is generally regarded as being ineffective.
Hello,
Yes, sorry I wasn't precise enough.
To improve the phone's performance, I had seen that it was possible to install a new ROM, but which one to choose and how to install it?
I initially tried to flash the phone using download mode, but it's impossible; the ODIN software doesn't even recognize the phone.
As for Google Play, I do have the app, but I can't download anything because the settings clearly show that Google Play isn't certified. I'll check with your method.
Thank you for your response.
Hello,
There is no point in flashing a recent phone; this process is meant to install a recent version of Android on an old phone that doesn't support it because very old Android versions do not support certain applications.
It's an unofficial operation that, when hardware allows, does not improve performance in any way (which performance?), and is not done simply through ODIN but requires rooting the phone, which is dangerous because it can render the phone completely unusable.
If Google Play is present but not Play Protect certified, it means it is a non-certified model (which is not the case), used and rooted (probably not either) or intended for a market without Play Protect certification (here the Chinese market).
One then needs to certify it using its ID, which can be obtained either by an adb command in root mode (impossible if it is not rooted) or with a dedicated application; it’s a vicious circle because downloading is not possible; thus, one must download the apk on a PC and transfer it via USB (phone in USB debugging mode if necessary, data cable and not charging cable, Samsung adb driver on the PC) to the Downloads folder on the phone or wherever desired, and of course allow installation from unknown sources.

Hello,
I agree, but right now the phone is really not performing (it's slow and the battery barely lasts a day with just messaging and calling), I'm not even sure it's the S23 Ultra. I saw that installing a Custom ROM could solve the problem, but I'm stuck on that. I’m aware of the risks, but today the phone is unusable (a commercial solution will be provided by the salesperson, so since I have a phone that's useless, I prefer to give it a try).
Google Play is present, but since it's a Chinese phone, it's not certified. I already tried to certify it with the tutorial you gave me, but it doesn't work. I can't download my daily apps (emails, banking, etc.).
Thank you for your response.
You can find ROMs on phonandroid, xda, and similar sites, at your own risk as I’ve already mentioned; it only takes the wrong version or a mistake in the process to ruin your phone with no hope of recovery.
Even when it works, there are drawbacks (for example, no more updates or warranty).
Now, as for the Chinese products, my thoughts on them...
My old phone died unexpectedly, so I bought one in a physical store at full price (an Oppo for €240, I could have found it on a reliable online site for €180-190), it’s not slow and the battery lasts at least 3 days with "phone and SMS use," isn’t life beautiful?
I am aware of the risks, but this is really a low-end phone.
This phone was originally a backup phone, so I'm giving it a try and I'm going to repair my Oppo Find X, which I actually paid €1 for (broken screen).
I suspected that by buying from AliExpress I wouldn't get the real model, but now it's unusable.
I could very well pay €200 for a phone; I am even an accountant for a major telecom brand, so I know the prices, but unfortunately, I can't afford it; everyone has their means...
